Furniture is one of the important media, contacts and relationships between building it by their own different shape and size provide comfortable environment for people. Ergonomics is the study of human activity and the claim size on the surrounding environment, how to make furniture to better serve people＇ s life and work. Our research proposed novel paradigm of the man-machine engineering theory which is meaningful.展开更多

Due to the requirement of the air market, the six planes are arranged separately in Nanchang, Shanghai, Fuzhou and Ningbo, thus the six planes are maintained in four places, which is unique among China展开更多
