Song Li [1] (1166—1243) was born in Qiantang (now Hangzhou) in the Song Dynasty. He was born in poverty and worked as a carpenter when he was young. A good painting is far away. Li Congxun, a court painter, accepted him as his adopted son, who taught him painting skills and eventually became a generation of famous artists. Song Guangzong, Song Ningzong and Song Lizong have three generations (1 190- 1264) of painting academies, and people respectfully call them "the old painters of the Three Dynasties". In painting, people have to learn from teaching, especially in border painting. The figure painting is meticulous and full of vitality; Flower-and-bird painting is exquisite and rigorous, and does not feel complicated and plain; Landscape painting is managed by artists and fascinating. There is no ruler in boundary painting, and the rules of palaces and pavilions are all prepared with rope ink, which is extraordinary. The painting themes are rich and colorful, from the palace to the folk, from the city to the countryside, from production to life, from eating and drinking to entertainment, from the fairy mountain to the Dragon Palace, from history to reality, all of which are reflected in the painting to reflect the rural customs and farmers' lives. There are exquisite courtyard paintings and more than 50 recorded works. Such as "Huang Ming Cockfighting Map" and "Hua Lantu"; There are genre paintings with simple lines and light colors, such as the map of the peddler; There are also landscape paintings rendered in ink, such as the West Lake. Handed down from ancient times, there are four years of Jiading (12 1 1), such as the volume of the peddler's map, the page of Hua Lantu, and the picture of the skull, which are collected in the Palace Museum. The West Lake Map is collected in Shanghai Museum; Listen to Ruantu and see the lake. There is also a landscape painting handed down from Song Li called Liangshuitang, which is collected by the National Palace Museum. Other works that have been handed down from generation to generation include Cow in Spring, Tian Shi, Lotus Picking, Tide Watching and so on. Later painters wrote, "Shi Li knows the interests of farmers best."

Song Li's genre paintings are more famous. He painted many genre paintings of rural life that showed the life of the lower class, and described the life of the working people as an aesthetic object, which was of great significance in the history of the development of ancient art in China.

There are many kinds of books in the map of the peddler, among which the Palace Museum is the best. This painting depicts a vendor in the countryside, surrounded by children, full of strong local flavor. The central axis of the "Fantasy Picture of Skeleton" in the Palace Museum has a good expression, and there are head and tail patterns on the clothes, mostly straight lines, thin and powerful.

[Edit this paragraph] Second, Associate Professor Tsinghua University

brief introduction

199 1, Xi jiaotong university got a bachelor's degree in engineering mechanics, 1994, Xi jiaotong university got a master's degree in vibration, shock and noise, 1999, and Tsinghua University engineering mechanics got a doctorate in fluid mechanics. Since then, he has been teaching at school. He is currently an associate professor at the Institute of Fluid Mechanics of Tsinghua University Institute of Aeronautics and Astronautics, and a member of China Aerodynamics Association and Industrial Aerodynamics Professional Committee.

Research direction: design method and new product development of high-performance fan, fan noise mechanism and numerical prediction method, aerodynamic noise mechanism and control, internal flow field analysis and airflow organization of dust collector, etc.

He has been responsible for and undertaken the scientific research and application development research of fan design and new product development, noise prediction and control, internal flow field analysis and airflow organization of dust collector, nonlinear acoustics, membrane distillation and other disciplines. He has published more than 20 papers in important magazines and international conferences at home and abroad, among which 6 papers have won invention patents and 2 utility model patents.

Major projects under study

National Natural Science Foundation Project "Study on Mechanism and Application of New Qualcomm Air Gap Membrane Distillation System"

Research on Combustion Noise Control of Aeroengine (International Cooperation Project with GE Company of America)

In 2002, two domestic central air-conditioning fans (international cooperation projects) were developed for GE Company in the United States.

In 2003-2004, he cooperated with Daikin Company of Japan in "Noise Analysis of Indoor Unit of Embedded Air Conditioning" (an international cooperation project).

[There are many new product development projects for fans, including new high-performance fans for large boilers and sintering, mine anti-cyclones, large high-pressure centrifugal fans, fans for range hoods, new fire-fighting smoke exhaust fans, axial fans, and fans for various air conditioners.
