WEBVTT 1 00:00:11.150 --> 00:00:11.680 Well 2 00:00:14.150 --> 00:00:17.090 My topic today is regional urban and rural development. 3 00:00:17.790 --> 00:00:21.330 So I know we have a lot of different majors 4 00:00:21.330 --> 00:00:22.990 Let's take this class 5 00:00:24.590 --> 00:00:27.610 Based on the difference between different majors 6 00:00:28.040 --> 00:00:35.080 I think we are here in this lesson, perhaps my own understanding will have two different levels of the subject. 7 00:00:35.080 --> 00:00:35.910 Content 8 00:00:36.400 --> 00:00:41.840 One content is the target of the area of urbanization. 9 00:00:42.300 --> 00:00:43.900 Everyone should have an understanding. 10 00:00:44.600 --> 00:00:45.050 The second 11 00:00:45.500 --> 00:00:47.020 On this basis 12 00:00:47.260 --> 00:00:56.240 We use our respective professional knowledge to solve the problems in the development of urbanization. 13 00:00:57.070 --> 00:00:59.890 Intelligent urbanization is one aspect. 14 00:00:59.890 --> 00:01:03.790 Is a directional content 15 00:01:03.790 --> 00:01:07.210 But where does this intelligence work? 16 00:01:07.510 --> 00:01:08.800 What is its goal? 17 00:01:09.280 --> 00:01:11.810 This requires our professional work together. 18 00:01:12.270 --> 00:01:15.240 Of course, after we have mastered the knowledge. 19 00:01:15.420 --> 00:01:21.410 It can be said that we can come together for a pair on an object above a certain region. 20 00:01:22.230 --> 00:01:25.720 For him to carry out some targeted research. 21 00:01:25.910 --> 00:01:27.020 Put forward countermeasures 22 00:01:27.530 --> 00:01:32.170 First of all, we have to understand that the basis is the object itself. 23 00:01:32.610 --> 00:01:35.850 What I am talking about today is mainly about the region. 24 00:01:35.850 --> 00:01:38.470 We are all very familiar with each other. 25 00:01:38.730 --> 00:01:44.980 But it is also very strange in urban and rural areas, cities and villages, we are very familiar with. 26 00:01:45.190 --> 00:01:47.400 But understand this feature. 27 00:01:47.580 --> 00:01:49.590 I think we need some time. 28 00:01:49.780 --> 00:01:56.030 And it is necessary to use a different from the ordinary people of such a perspective to look at the problem. 29 00:01:56.610 --> 00:01:59.240 So here I would like to talk about these aspects. 30 00:01:59.240 --> 00:02:01.790 Talk about four major aspects 31 00:02:02.030 --> 00:02:04.820 The first aspect is cities and regions. 32 00:02:05.900 --> 00:02:11.460 So the urban area actually includes the countryside 33 00:02:12.010 --> 00:02:14.190 So in this big relationship 34 00:02:14.190 --> 00:02:17.580 What kind of relationship do we have between urban and rural areas? 35 00:02:18.510 --> 00:02:20.730 We can separate the city from the countryside. 36 00:02:20.940 --> 00:02:23.710 Before in the last century 37 00:02:24.100 --> 00:02:28.710 One of our goals is to narrow the gap between urban and rural areas. 38 00:02:29.510 --> 00:02:31.360 Then there is a gap between urban and rural areas. 39 00:02:31.360 --> 00:02:33.380 It means that these are two different groups. 40 00:02:33.380 --> 00:02:34.690 Different regions 41 00:02:35.410 --> 00:02:36.640 What is the relationship? 42 00:02:37.190 --> 00:02:43.670 In addition, we should pay attention to how to develop urban and rural areas on the basis of this relationship. 43 00:02:44.840 --> 00:02:48.280 Finally, I introduce a case-based. 44 00:02:48.280 --> 00:02:50.480 Introduce a smart city 45 00:02:50.720 --> 00:02:52.320 Or we're talking about intelligence here 46 00:02:52.500 --> 00:02:57.190 In fact, how to apply the technology in the development of the city? 47 00:02:57.190 --> 00:03:01.300 Using some means to solve the problems in urban development 48 00:03:01.300 --> 00:03:03.350 Or lead to better urban development. 49 00:03:03.580 --> 00:03:03.810 Right 50 00:03:03.810 --> 00:03:04.590 So this is 51 00:03:04.800 --> 00:03:05.150 Well 52 00:03:05.150 --> 00:03:06.470 So the first 53 00:03:06.470 --> 00:03:08.740 People are very familiar with the city. 54 00:03:09.510 --> 00:03:10.660 What is the city? 55 00:03:11.000 --> 00:03:12.460 You can think about it. 56 00:03:12.460 --> 00:03:14.300 What can be done in the city? 57 00:03:15.100 --> 00:03:17.400 So this is very simple, it is a common sense. 58 00:03:17.400 --> 00:03:19.800 Everyone lives in the city. 59 00:03:19.970 --> 00:03:21.860 Or living in the countryside 60 00:03:21.860 --> 00:03:23.850 But people who yearn for the city 61 00:03:24.060 --> 00:03:25.710 He has his own answers. 62 00:03:26.120 --> 00:03:32.360 Each individual has a different educational background at different levels. 63 00:03:32.360 --> 00:03:33.950 Will have their own answers. 64 00:03:34.440 --> 00:03:37.870 I think the answer is a classic. 65 00:03:38.080 --> 00:03:43.160 The answer is that there was an international organization in 1933. 66 00:03:43.160 --> 00:03:47.520 An organization for modern urban movement 67 00:03:47.520 --> 00:03:49.720 There was a meeting somewhere 68 00:03:49.720 --> 00:03:52.200 That place is in Athens, Greece. 69 00:03:52.200 --> 00:03:55.010 Then come up with an Athenian charter 70 00:03:55.720 --> 00:03:57.580 The charter States that 71 00:03:57.580 --> 00:04:01.450 The four major functions of a city have four major functions. 72 00:04:01.450 --> 00:04:03.740 Residential work, transportation and recreation 73 00:04:04.140 --> 00:04:05.920 We all know these four functions. 74 00:04:05.920 --> 00:04:06.380 Well 75 00:04:07.060 --> 00:04:08.060 You can also think about it. 76 00:04:08.060 --> 00:04:10.820 Everyone has their own experience according to their own experience. 77 00:04:10.820 --> 00:04:12.320 Think about what else 78 00:04:12.320 --> 00:04:13.300 Is it all here? 79 00:04:13.300 --> 00:04:17.150 Or do I have a fifth? 80 00:04:17.410 --> 00:04:26.820 So what I want to say is what kind of area is our function in? 81 00:04:26.820 --> 00:04:28.050 Bring into play 82 00:04:28.290 --> 00:04:31.970 We are going to pay attention to the living work of this city. 83 00:04:31.970 --> 00:04:34.210 The four functions of traffic game 84 00:04:34.210 --> 00:04:36.380 What are you looking for? 85 00:04:37.740 --> 00:04:43.630 This is what we have to manage our traffic. 86 00:04:43.780 --> 00:04:45.140 Environmental 87 00:04:45.140 --> 00:04:47.230 To fall on an object 88 00:04:47.720 --> 00:04:50.570 So this is the most basic thing we should pay attention to 89 00:04:50.730 --> 00:04:52.840 So I think from the most basic point of view 90 00:04:53.280 --> 00:04:57.230 We should say that there are many kinds of objects. 91 00:04:57.700 --> 00:05:03.530 The first one here is called functional administrative region. 92 00:05:03.730 --> 00:05:04.390 City 93 00:05:05.250 --> 00:05:10.660 Shanghai, Beijing, Guangzhou, Shenzhen, Hangzhou, Nanjing, Suzhou and so on. 94 00:05:11.330 --> 00:05:13.820 The concept of this correspondence is that this is a 95 00:05:13.820 --> 00:05:15.650 Add one to the back 96 00:05:16.240 --> 00:05:16.560 Well 97 00:05:16.560 --> 00:05:18.190 This is a municipality directly under the central government 98 00:05:18.550 --> 00:05:24.740 Like Suzhou, Nanjing, Hangzhou, Ningbo, Qingdao, Shenzhen and so on. 99 00:05:24.850 --> 00:05:27.860 Guangzhou and so on these sub-provincial cities. 100 00:05:28.430 --> 00:05:30.130 There are a lot of prefecture-level cities. 101 00:05:30.320 --> 00:05:31.320 There are also very solo photos. 102 00:05:31.320 --> 00:05:38.170 Even now, some people are saying that there is a need to strive for the establishment of an additional correction market. 103 00:05:38.620 --> 00:05:40.460 Our general town a Cheng 104 00:05:41.070 --> 00:05:42.630 This is a good administration. 105 00:05:42.630 --> 00:05:44.590 This is an administrative concept. 106 00:05:44.770 --> 00:05:45.960 Administrative territory 107 00:05:46.430 --> 00:05:47.770 Area 108 00:05:47.770 --> 00:05:53.400 All three one two three four four pieces add together 109 00:05:54.120 --> 00:05:55.250 How much is added together 110 00:05:55.250 --> 00:06:00.080 About 6700 square kilometers. 111 00:06:00.510 --> 00:06:03.100 I said it probably because I don't know much. 112 00:06:03.340 --> 00:06:06.710 Because the number I know is 6340. 113 00:06:06.710 --> 00:06:08.520 This is the data from the statistical yearbook. 114 00:06:08.700 --> 00:06:11.820 But in fact, the number is now larger than his. 115 00:06:11.820 --> 00:06:16.930 For example, the d growing out of these beaches is constantly changing. 116 00:06:16.930 --> 00:06:17.180 Well 117 00:06:17.180 --> 00:06:20.840 If we engage in the field of land management students know that it is called reserve. 118 00:06:21.020 --> 00:06:23.250 This is the reserve land resources. 119 00:06:24.190 --> 00:06:27.110 So these but let's think about it 120 00:06:27.250 --> 00:06:29.190 A city like Shanghai. 121 00:06:29.190 --> 00:06:31.060 It has more than 6000 square kilometers. 122 00:06:31.460 --> 00:06:33.820 Or a city like Beijing. 123 00:06:33.820 --> 00:06:36.340 It has 16800 square kilometers. 124 00:06:37.680 --> 00:06:43.890 The city of these functions is not the play of such a region is certainly not. 125 00:06:44.240 --> 00:06:45.980 Function of Shanghai 126 00:06:46.180 --> 00:06:48.320 Shanghai according to the requirements of the state. 127 00:06:48.320 --> 00:06:53.110 In accordance with the requirements of Shanghai city to play its own role. 128 00:06:53.110 --> 00:06:56.110 Shanghai must have at least four centers. 129 00:06:56.690 --> 00:06:59.230 Take the word international in front of both. 130 00:06:59.490 --> 00:07:01.060 International economy 131 00:07:01.660 --> 00:07:04.450 Financial trade shipping 132 00:07:05.470 --> 00:07:10.700 So there are a lot of innovation centers that are now being extended, right? 133 00:07:10.700 --> 00:07:12.920 Culture has a lot of this connotation. 134 00:07:13.200 --> 00:07:15.080 So it's obvious 135 00:07:15.080 --> 00:07:17.390 He's not just in this range. 136 00:07:18.660 --> 00:07:20.730 Bigger than much 137 00:07:21.120 --> 00:07:22.650 Let's make it simple. 138 00:07:22.650 --> 00:07:24.220 We are going to fall into this concept. 139 00:07:24.470 --> 00:07:26.610 Call it the role of the city 140 00:07:26.610 --> 00:07:29.290 Give full play to the function of the city 141 00:07:29.290 --> 00:07:32.040 There is another functional area that corresponds to it. 142 00:07:33.140 --> 00:07:37.820 If a city, its functional areas and administrative areas are consistent. 143 00:07:37.820 --> 00:07:38.800 This is the ideal. 144 00:07:39.190 --> 00:07:41.990 But most of them don't match. 145 00:07:42.810 --> 00:07:43.730 Like Shanghai 146 00:07:44.100 --> 00:07:46.680 So how big is Shanghai's regional function? 147 00:07:47.270 --> 00:07:48.700 Let's talk less 148 00:07:48.950 --> 00:07:50.450 100,000 square kilometers 149 00:07:50.730 --> 00:07:57.150 That is, the Yangtze river delta with Shanghai as its center. 150 00:07:57.800 --> 00:08:01.090 The Yangtze river delta refers to 16 cities. 151 00:08:01.650 --> 00:08:03.280 Everyone will be familiar with it. 152 00:08:03.280 --> 00:08:07.150 Let me just say a few words about su Xi Chang a Ning Zhen Yang 153 00:08:07.540 --> 00:08:09.680 Eight States in Nantong 154 00:08:10.130 --> 00:08:10.880 Hang 155 00:08:10.960 --> 00:08:20.440 Hangzhou, Zhejiang Jiaxing Huzhou, Shaoxing, Ningbo, Zhoushan, Taizhou seven eight plus one 16. 156 00:08:20.440 --> 00:08:21.070 City 157 00:08:21.470 --> 00:08:22.250 How much is this 158 00:08:22.250 --> 00:08:24.350 A tree of 100,000 square kilometers 159 00:08:24.810 --> 00:08:26.430 It is not enough to say now. 160 00:08:26.430 --> 00:08:27.890 Why do you count Taizhou 161 00:08:27.890 --> 00:08:28.990 Wenzhou does not count 162 00:08:29.400 --> 00:08:33.670 Why some areas in Anhui near Jiangsu and Zhejiang are not good? 163 00:08:33.670 --> 00:08:35.510 Add these together 164 00:08:35.510 --> 00:08:36.820 Then it might add up 165 00:08:36.820 --> 00:08:37.780 Seven more cities 166 00:08:37.780 --> 00:08:39.440 Could be 23 cities 167 00:08:39.440 --> 00:08:45.810 Plus Wenzhou plus ma on Shan, Wuhu, Hefei, Xuancheng and so on these cities. 168 00:08:46.360 --> 00:08:49.730 It's 23, how many, almost 190, 000 square kilometers. 169 00:08:50.930 --> 00:08:51.810 Not enough 170 00:08:51.810 --> 00:08:53.280 There are some areas outside. 171 00:08:54.350 --> 00:08:58.960 We are talking about Zhejiang, Jiangsu, Jiangsu and Jiangsu provinces. 172 00:08:59.400 --> 00:09:01.760 Talk about Zhejiang except north Anhui province 173 00:09:01.760 --> 00:09:03.480 And south west 174 00:09:03.740 --> 00:09:05.060 And these are not reported 175 00:09:05.060 --> 00:09:08.790 Jiangsu, Zhejiang and Shanghai all together more than 20 million square kilometers. 176 00:09:09.260 --> 00:09:12.510 So now we talk about the Yangtze river delta very clearly. 177 00:09:12.510 --> 00:09:19.200 How big is Shanghai, three provinces and one city this evening? 178 00:09:19.200 --> 00:09:20.620 350, 000 square kilometers 179 00:09:21.020 --> 00:09:21.620 So good 180 00:09:21.620 --> 00:09:22.640 You leave one for everyone 181 00:09:22.640 --> 00:09:24.110 Let's think about it 182 00:09:24.700 --> 00:09:26.140 Within this range 183 00:09:26.450 --> 00:09:27.790 How many people 184 00:09:28.330 --> 00:09:30.990 How many people are there in Jiangsu, Zhejiang and Shanghai? 185 00:09:31.220 --> 00:09:33.010 What is the total population of the country? 186 00:09:33.190 --> 00:09:34.140 This is a 187 00:09:34.470 --> 00:09:38.120 Jiangsu, Zhejiang and Shanghai: what is its total economic GDP? 188 00:09:38.330 --> 00:09:40.150 What is the proportion of the whole country? 189 00:09:40.650 --> 00:09:43.440 So we can think about it and think about it. 190 00:09:43.440 --> 00:09:44.430 So let me tell you something 191 00:09:44.430 --> 00:09:48.930 Now according to 12 years of 12 13 years 192 00:09:48.930 --> 00:09:52.290 It accounts for a quarter of the country's total. 193 00:09:53.310 --> 00:09:56.850 The population is about 16%. 194 00:09:57.660 --> 00:10:03.740 The area of the area, it can be removed 350, 000 square kilometers divided by the area of 9.6, 000 land areas. 195 00:10:03.930 --> 00:10:05.670 So this is a correspondence 196 00:10:05.670 --> 00:10:05.870 Well 197 00:10:05.870 --> 00:10:07.510 We can look at this picture, can't we? 198 00:10:07.510 --> 00:10:08.520 Go check 199 00:10:08.520 --> 00:10:10.850 So look at the picture in the back 200 00:10:10.850 --> 00:10:12.760 Basically, this range is corresponding. 201 00:10:13.210 --> 00:10:16.640 So what is the difference between this and the previous picture? 202 00:10:16.640 --> 00:10:18.430 There are a lot of traffic lines on it. 203 00:10:18.910 --> 00:10:20.060 There are a lot of traffic lines. 204 00:10:20.250 --> 00:10:23.120 Those of us who are going to study transportation may be familiar with us. 205 00:10:23.120 --> 00:10:24.800 Because this traffic line is very important. 206 00:10:24.800 --> 00:10:25.260 Right 207 00:10:25.260 --> 00:10:28.610 What is the most important thing in the development of cities and regions? 208 00:10:28.610 --> 00:10:30.420 The most important thing is vitality. 209 00:10:30.850 --> 00:10:32.550 He will move the living thing. 210 00:10:32.750 --> 00:10:33.470 Right or wrong 211 00:10:33.470 --> 00:10:34.960 So what's moving 212 00:10:35.370 --> 00:10:36.150 Stream of people 213 00:10:36.430 --> 00:10:40.020 Logistics capital flow information flow 214 00:10:40.200 --> 00:10:41.570 And technology 215 00:10:41.570 --> 00:10:42.430 There are others 216 00:10:42.430 --> 00:10:43.900 A lot of it is moving 217 00:10:44.380 --> 00:10:45.250 The more frequent 218 00:10:45.250 --> 00:10:46.800 It means the place is alive 219 00:10:48.190 --> 00:10:52.280 There are places where you go to see him without a floating population. 220 00:10:52.790 --> 00:10:54.860 Only those outside the household registration population. 221 00:10:55.020 --> 00:10:57.160 This place must not develop. 222 00:10:57.420 --> 00:10:58.560 Because there is no energy 223 00:10:58.820 --> 00:11:00.360 There is not much foreign content. 224 00:11:00.360 --> 00:11:01.620 So this has to correspond 225 00:11:01.620 --> 00:11:01.880 Well 226 00:11:01.880 --> 00:11:03.560 We found it in this city. 227 00:11:03.560 --> 00:11:05.060 Do a good job of the whole city 228 00:11:05.300 --> 00:11:09.430 Through this need to drive the development of this place. 229 00:11:11.680 --> 00:11:15.890 So come back and look at this picture 230 00:11:16.570 --> 00:11:17.910 Throughout the region 231 00:11:17.910 --> 00:11:21.250 We know Shanghai knows Suzhou Wuxi Changzhou. 232 00:11:21.710 --> 00:11:23.170 I also know Taicang 233 00:11:23.170 --> 00:11:25.800 Know these Jiangyin 234 00:11:26.250 --> 00:11:27.290 Same as below 235 00:11:27.290 --> 00:11:28.400 Below knows 236 00:11:28.770 --> 00:11:31.600 Jiaxing Hangzhou Ningbo 237 00:11:32.440 --> 00:11:35.140 If we say we should pay attention to its development. 238 00:11:35.690 --> 00:11:40.240 Now this one is not visible along these lines. 239 00:11:40.650 --> 00:11:42.330 What are we going to add? 240 00:11:43.370 --> 00:11:46.880 We learn about the planning of the road network. 241 00:11:47.040 --> 00:11:48.920 Why do you want to add a line here? 242 00:11:50.420 --> 00:11:51.760 Why do you want to add a line here? 243 00:11:51.800 --> 00:11:54.180 Instead of this main set here now. 244 00:11:54.220 --> 00:11:54.780 Right 245 00:11:55.420 --> 00:11:59.730 It should be linked to its economy, its society and its functions. 246 00:12:00.030 --> 00:12:01.920 So there are two different sets of graphs 247 00:12:01.930 --> 00:12:03.360 Give us two different tasks 248 00:12:03.360 --> 00:12:06.000 A traffic line 249 00:12:06.170 --> 00:12:10.900 How can we adapt to the conditions of this traffic development? 250 00:12:11.490 --> 00:12:14.400 To promote urban development 251 00:12:14.840 --> 00:12:16.800 There is no picture in front of the second one over there. 252 00:12:16.800 --> 00:12:21.010 How do we consider the attributes of these regions to connect? 253 00:12:21.020 --> 00:12:22.650 Link the contents together 254 00:12:23.020 --> 00:12:23.840 So this is a 255 00:12:24.060 --> 00:12:28.520 Then of course, just talked about a concept is the landscape, right? 256 00:12:28.810 --> 00:12:30.420 From a management perspective 257 00:12:30.800 --> 00:12:32.820 The city must be different from the country. 258 00:12:33.050 --> 00:12:34.130 Different where is it 259 00:12:34.410 --> 00:12:40.980 It is necessary to put forward the different regional management. 260 00:12:40.980 --> 00:12:44.200 Then I'll look for these four pictures 261 00:12:44.200 --> 00:12:46.250 So these four pictures must be known. 262 00:12:46.290 --> 00:12:48.710 Small rural town 263 00:12:49.240 --> 00:12:51.900 Small cities to big cities 264 00:12:52.120 --> 00:12:52.700 Right 265 00:12:53.300 --> 00:12:54.880 What we can see is different. 266 00:12:56.330 --> 00:12:57.590 The landscape is different 267 00:12:57.950 --> 00:12:59.560 The intensity of development is different. 268 00:12:59.790 --> 00:13:00.120 Well 269 00:13:00.120 --> 00:13:01.790 Behind seeing these 270 00:13:01.790 --> 00:13:03.640 If our classmates in economics 271 00:13:03.950 --> 00:13:07.680 Our students at the school of economics and management may have to pay attention to what's behind it. 272 00:13:08.120 --> 00:13:09.460 Behind it is the economy. 273 00:13:09.790 --> 00:13:13.400 All kinds of social and cultural exchanges. 274 00:13:13.560 --> 00:13:16.270 So I think this is the first we have to understand this object. 275 00:13:16.360 --> 00:13:19.440 What is the object of the area we are talking about? 276 00:13:19.860 --> 00:13:23.330 So this object has 277 00:13:23.330 --> 00:13:25.720 Of course, we are talking about the city now, which is very important. 278 00:13:25.860 --> 00:13:26.300 Right 279 00:13:26.300 --> 00:13:28.490 So this concept of a city like this 280 00:13:28.620 --> 00:13:32.020 It's for the whole area 281 00:13:32.140 --> 00:13:33.280 What are the characteristics? 282 00:13:33.630 --> 00:13:36.150 There are two different explanations. 283 00:13:36.150 --> 00:13:39.510 It can be explained from a different perspective. 284 00:13:40.780 --> 00:13:42.560 I drew a little bit below. 285 00:13:42.560 --> 00:13:43.910 We have many other explanations 286 00:13:44.260 --> 00:13:44.730 Right 287 00:13:44.960 --> 00:13:52.600 This interpretation actually means that we have to put a lot of these elements in this. 288 00:13:52.600 --> 00:13:53.050 Upper 289 00:13:53.240 --> 00:14:00.040 In fact, we can see the space to see this person to see the space of such a human resources, and so on. 290 00:14:00.040 --> 00:14:01.230 A state 291 00:14:01.240 --> 00:14:02.780 Is a state of gathering 292 00:14:03.010 --> 00:14:04.990 Seeing these people is a trait. 293 00:14:04.990 --> 00:14:06.120 Non-agricultural 294 00:14:06.270 --> 00:14:08.170 Engaged in the secondary and tertiary industries 295 00:14:08.630 --> 00:14:10.490 Include non-agricultural 296 00:14:10.530 --> 00:14:12.430 And gather in space 297 00:14:12.430 --> 00:14:13.550 Have a certain density 298 00:14:13.550 --> 00:14:15.210 Have a certain development intensity. 299 00:14:15.670 --> 00:14:16.110 Right 300 00:14:16.370 --> 00:14:17.630 This is his request. 301 00:14:18.180 --> 00:14:23.560 So we should pay attention to the theme of sustainable intelligent urbanization. 302 00:14:23.610 --> 00:14:24.920 We should pay attention to this object. 303 00:14:24.920 --> 00:14:26.520 To see what's in it 304 00:14:27.450 --> 00:14:28.760 What's in it? 305 00:14:28.760 --> 00:14:30.620 It shows first 306 00:14:30.790 --> 00:14:33.480 So I'm going to talk about our subjects 307 00:14:34.400 --> 00:14:39.170 If this is the science of engineering. 308 00:14:39.910 --> 00:14:41.730 Even the liberal arts 309 00:14:41.730 --> 00:14:43.060 Is that we have to study an object 310 00:14:43.070 --> 00:14:46.860 I say the simplest is three key words. 311 00:14:47.210 --> 00:14:48.520 First phenomenon 312 00:14:49.160 --> 00:14:50.560 You must make clear the phenomenon. 313 00:14:50.990 --> 00:14:52.820 By observation 314 00:14:53.240 --> 00:14:55.150 We can observe with human eyes. 315 00:14:55.380 --> 00:14:57.950 Use the data to observe our traffic classmates. 316 00:14:58.000 --> 00:15:04.180 Now why can the entire city trunk road network of traffic so clear. 317 00:15:04.410 --> 00:15:06.030 Because we have technology 318 00:15:06.030 --> 00:15:09.440 Each of us has a cell phone in his pocket. 319 00:15:09.480 --> 00:15:11.250 Is a mobile terminal 320 00:15:11.250 --> 00:15:17.150 The mobile terminal will be with the base station every minute and every minute and every minute and every few minutes. 321 00:15:17.150 --> 00:15:18.170 A connection 322 00:15:18.440 --> 00:15:21.710 Send the signal from your mobile phone to the base station 323 00:15:21.750 --> 00:15:27.330 So this base station can know how fast the mobile phone is moving every once in a while. 324 00:15:27.740 --> 00:15:31.840 Especially in the inner ring viaduct north-south Yanan viaduct 325 00:15:31.880 --> 00:15:32.940 On the elevated line 326 00:15:32.940 --> 00:15:35.080 Just know what the speed of this car is. 327 00:15:35.290 --> 00:15:36.300 We have the means 328 00:15:36.300 --> 00:15:36.870 Well 329 00:15:36.870 --> 00:15:38.140 We have this phenomenon 330 00:15:38.150 --> 00:15:42.140 Second, we need to understand the law of this phenomenon. 331 00:15:43.530 --> 00:15:46.840 Central in central Shanghai started very well. 332 00:15:47.250 --> 00:15:48.070 Eighty kilometers 333 00:15:48.070 --> 00:15:50.900 Sometimes I think the line speed is too slow. 334 00:15:51.220 --> 00:15:52.890 But now it is often blocked. 335 00:15:53.130 --> 00:15:54.180 Where to block 336 00:15:54.230 --> 00:15:56.690 Block where it hit 337 00:15:57.250 --> 00:15:58.350 Just make it clear 338 00:15:58.360 --> 00:16:00.240 Our road is clear. 339 00:16:00.240 --> 00:16:02.550 But with the following ramp 340 00:16:02.590 --> 00:16:03.300 This is the problem. 341 00:16:03.300 --> 00:16:04.290 This is the law. 342 00:16:05.090 --> 00:16:07.370 So what's working on this rule? 343 00:16:07.420 --> 00:16:09.270 This is the third word called mechanism. 344 00:16:09.500 --> 00:16:13.140 So the mechanism of the law of the phenomenon of six words in this 345 00:16:13.180 --> 00:16:17.050 This is the study of all disciplines should pay attention to. 346 00:16:17.340 --> 00:16:20.300 So, as we do research, we often use a few symbols. 347 00:16:20.340 --> 00:16:24.620 Three w1, one H1, one is Y1, and one is what 348 00:16:24.620 --> 00:16:26.810 One is y and there is a number. 349 00:16:26.820 --> 00:16:27.860 And wait 350 00:16:27.860 --> 00:16:29.460 You have to pay attention to these things. 351 00:16:29.610 --> 00:16:30.010 Right 352 00:16:30.050 --> 00:16:32.530 So there are some good things for the city 353 00:16:32.530 --> 00:16:34.040 So we look at it from a city point of view 354 00:16:34.080 --> 00:16:36.370 What do we want to pay attention to this city? 355 00:16:36.690 --> 00:16:38.690 Pay attention to the changes in its development. 356 00:16:38.690 --> 00:16:42.260 Pay attention to what we can see in the course of its development. 357 00:16:42.780 --> 00:16:43.340 Well 358 00:16:43.340 --> 00:16:44.370 This is a
