Ancient Chinese culture is the ethnic roots of modern design, dig national heritage, know the trend of the world, is the foundation of modern design.The design of ancient China, from the natural, the natural, farming and hunting for food.Summer clothing, through the mountains on the potential, civil house, production and life practice long, accumulated rich experience and inspiration."
Refer to product design, research data related to the United States, introduced from Europe and other countries, very few Chinese related information, file design in ancient China, a lot of books are interpreted from the other, history, culture and so on, there are very few studies on Chinese ancient human engineering design in relevant.Can China regarding ergonomics long-standing, especially in ancient times of China, the relationship between human, material, environment of the three has always been the main content of design research in ancient china.Human engineering is an important part of design, a good design a lot of ancient China, and these works today is in use, or by reference design.These works are excellent, to some extent, is because of the excellent design works in the development process, and all reflect the human engineering, human nature is reflected design.In terms of a product, the development process is also the human understanding, to their own ability to understand
and use process, all reflect the human engineering ideas naive.Luban, Heavenly Creations, dream pool essays, history of science and technology.Such as "Luban" in the regular size, research and modern human engineering design agree without prior without previous consultation, the ancients have to conduct relevant research.
The traditional design of civil, pay attention to is the most practical, convenient, economical, compatible with the local people, at the time of the life, times have changed, the regional variable, use of population change, design will change.Easy materials selection, to cater to local society, reflected the people's spiritual pursuit, and coordinate with environment.Even a very simple design is the long-term accumulation of experience, is the crystallization of collective wisdom, is the communication between internal and external environment.Bamboo products design southern, northern rural areas still in use such tools are the flail design paradigm, but also the emotional communication between human and nature. 2.3 Reflect on the personal emotions Products put in on details, should be designed according to the physiological, psychological characteristics of different groups, make product design reflect the personal feelings.As a function of the products, different people have different

Introduction In china, as development of the west regions, some large-scale hydraulic and hydro-power engineering would be built for successful transmission of electricity from the western to the eastern region.
In recent years, the demands of rock mechanics and engineering practices have accelerated studies on unloading failure of rocks.
Relationship curves between mechanical indexes and confining pressure Rock failure criterion under the condition of unloading In geotechnical engineering, the Mohr-Coulomb criterion is the most commonly used in practice.

Theoretical Study of The Spherical Bearing Rotational Torque PENG Tianbo1,a, SHI Xianfei1,b, HAN Lei1,c 1 State Key Laboratory of Disaster Reduction in Civil Engineering, Tongji University, Shanghai 200092, China aptb@tongji.edu.cn,b929885801@qq.com,cmvp944630278@163.com Keywords: spherical bearing, rotational torque, bearing design, bearing test.
Considering the curvature radius of spherical bearing in practical engineering is usually larger than 360mm, and according to the mechanical characteristics in rotation of spherical bearing, the following assumptions can be made: a) The spherical cap suffers uniformly distributed pressure along the convex surface, pointing towards the center of the sphere; b) The pressure on the rotating plate imposed by the spherical cap flat surface is distributed as a right trapezoid. 2.2 Model establishment and analysis In the spherical bearing rotational test, two bearings are placed on and beneath the rotating plate respectively.
