I opened the learning platform to strengthen the country and clicked into the water conservancy course. what comes into view is introduction to civil engineering8, water conservancy and hydropower engineering. Soon the video stopped to show professor chenLingli. the keynote speaker of shanghai university. She didn't have much opening remarks and directly entered the content of water conservancy and hydropower projects. I quickly spread out the class notes. Record what She left on the screen. I listened to her systematic explanation. Not only can you understand every sentence, but also there is no pressure in your heart.
译，我打开学习强国平台，点击"走进水利”课程，映入眼帘的是土木工程概论–8（水利水电工程），很快视频就停了下来，显示"上海大学，主讲陈伶俐教授"。她没有多少开场白，直接进入水利水电工程内容，我迅速展开课堂笔记，记录她留在教学屏上的内容。我聆听着她系统的讲解，不仅句句能懂，而且心情舒畅。
I've heard a lot of lessons from famous masters. More or less nervous. Some are because of the speaker's introduction, Some are because of the speaker's clothes, Some are because of the entourage of the speaker. Listen to professor chen's class today. It is the greatest enjoyment of my teaching career. In short ,Listen to her water conservancy and hydropower engineering class. It seems to be satisfied with water conservancy knowledge, catharsis of farmer's emotions and confidence in future water conservancy research.From her class, I heard what the tourists wanted to understand, the natural water in china is characterized by the pattern of waterlogging in the south and drought in the north. But I have never made such a concise summary, what's going on in karez, xinjiang, She illustrated the structure of the karez, Groundwater irrigation leads to farmland intuitively. what's more wonderful is that She uses her travel experience. Describe the stability of Dujiangyan water conservancy project, After wenchuan big , She travels there, the temple on the mountain has been repaired for a long time, But it hasn't been repaired yet. But dujiangyan water conservancy project was not damaged in the earthquake. From her class. Learned about the role of jiangdu water control project station in the south-to-North water Transfer，Show the world the strength of electric drainage and irrigation projects in china's water conservancy.
译，我听过名家大师的课很多，或多或少都紧張过，有的是因为演讲者的介绍；有的是因为演讲者的衣冠；有的是因为演讲者的随从阵势。今天听陈教授的课，是我听课生涯中的最大的亨受。总之，听她这一节水利水电工程课，仿佛得到水利知识的满足，农民情感的宣泄以及对未来水利工作研究的信心。从她课堂上，我听到旅游者们想明白的内容，我国自然水的特点是南涝北旱的格局，但我从未作过这么言简意赅的总结，(对于)新疆的坎儿井，是怎么回事？她用坎儿井结构示意图，直观表达出，地下水引出地面，灌溉农田的过程，更精彩的是她用自己的旅游经历，描述都江堰水利工程的稳固性。汶川大地震后，她去那里旅游，山上的寺庙修了好長时间，还没修好，可都江堰水利工程，在地震中没有受损。从她课中，我了解江都水利枢纽站，在南水北调中的作用，向世界展示中国水利中，电力排灌工程的实力。
She can always tell the working principle and development basis of different froms of hydropower stations in simple terms, She has her own unique viens on Hydropower station development and development of clean energy and all kinds of energy, Especially the explanation of the function of pumped storage power station . Redistribute energy in time, It is both appropriate and unforgettable , I also associate this sentence with my learning experience. the57year old listening to a young professor today is also a redistribution of energy. the working principle of tidal power station is explained more vividly and intuitively, Use the potential energy of the water level difference between rising at falling tides to generate electricity. with a little knowledge of physics, I grew up by the sea and understood the truth after listening to it.
译，她总能深入浅出的说出：不同形式的水电站工作原理和开发依据。她对水电站开发，发展清洁能源和各类能源的应用，都有自己的独到见解。尤其是抽水蓄能电站作用的讲解，那句”在时间上，把能量重新分配"，既贴切形象，又令我难忘，我还把这句话，联系我的学习经历加以理解，57岁的我，在听年轻教授的课，也是种知识能量的再分配。潮汐水电站的工作原理，讲解得更加形象直观，是利用潮水漲，落发生的水位差所具有的势能发电，稍有物理知识，又在海边成長大的我，听后即刻明白其中的道理。
Hydraulic structures, her unique classification, the past events come clearly into view, from flood control planning and flood control works to river regulation, Finally，the structural form, function and precautions of the construction of the reservoir hub project are explained, It's like a special finale course for me, Because I am now engaged in the construction of reservoir hub project, Information on this is being collected She explained the reasons for the reduction of library capacity intuitively and clearly.
译，水工建筑物，她独到的分类，往事让我历历在目，从防洪规划，防洪工程，水到渠成的引入河道整治话题，最后又道出水库枢纽工程建设的构造形式，作用及注意事项。这仿佛是为我专门开设的人生压轴课程。因为我现在就从事水库枢纽工程建设，现在正收集有关这方面的资料和信息，她把库容量降低的原因，诠释得直观明了。
From the class, you can still hear her avant-garde thinking,the advanced rubber dam project has been tried out in the shine water conservancy project in xinyang, Henan province, china,Germany's light steel structure flood control technology can be used for reference, and the cost is too expensive to be taken,Sponge city is a part of flood control project, the role of flood discharge area planning should be fully explained in the four words of storage treatment and discharge, She succinctly stated the river regulation method, when I returned home this spring Festival, many leaders introduced the river regulation to me ,There are many languages which are difficult to express the content of the rectification work , of course, there are also Some leaders who are not professional and do not do in-depth and meticulous work, But from adjusting river regime, cutting bend and straightening, river widening and other words. unique understanding of sponge city construction. Lack of analysis and Research on flood control benefies ,During the hearing period, the water in the city is difficult to discharge,
改These problems have led to the closure of rivers and canals around the new city, She has a deep research on these aspects, It not only provides a thinking basis for the water conservancy planning department, provide reference for new urban infrastructure construction in urban development, Avoid the historical tragedy of turning the city into reservoir during the news period.
译，从她的课堂上，还能听出她思维的前卫，先进的橡胶坝工程，在我国河南信阳浉河水利中已试行；德国的轻钢结构防洪，技术上可以借鉴，造价太贵。不可取；海绵城市是防洪工程的一部分。她用蓄，治，用，泄四个字，把泄洪区规划的作用讲透，她简洁的说出河道整治方法，今年回乡，许多人向我介绍河道整治情况，用了很多语言，都难以表述清，整治工作的具体内容，当然还存在一些人不专业和工作不细致的问题。但从她总结的"调整河势，裁弯取直，河道展宽"等词语；对海绵城市建设独到的理解；像城市规划大量开发的失误；缺乏防洪效益分析研究；汛期城中积水难以泄出（城郊沟渠）。这些问题，导致新城周边河渠封闭，她对这些方面，有着深刻的研究，不仅给水利规划部门提供了思考依据，也给有关部门，在城市开发中，提供新型城市基础建设的参考，避免汛期城中再变成蓄水池的历史悲剧。
Although professor chen's podium experience is still insufficient , After listening to this class, I want to listen to the ontine open class of shanghai university again, As the saying goes, a teacher is a school sign. From this class, I know more about the collective sense of honor, which is created by each member of the collective, This is probably when Listen to professor chenLingli's open class at Shanghai university，Understanding of mechanics and Engineering science.
译，尽管陈教授讲台经验还存在不足，但我听了这堂课，想把上海大学所有网上公开课听一遍。俗话说，一个老师，就是一所学校的品牌，从她这节课，我更想了解上海大学，从而更认识集体荣誉感，是靠集体中每个成员创造的。这大概就是我听上海大学，陈伶俐教授公开课，对力学与工程科学的新理解。
