A simple tension calculation algorithm as well as a ratio index,a quality index,and a global quality index is proposed to measure the size and shape of the workspace of wire-driven parallel kinematic manipulators.

To improve the effectiveness of the elevator traction drive,three crucial parameters including car quality coefficient,accelerated speed,and balance coefficient that influence traction drive were analyzed and optimized.

On the basis of using quality coefficient to quantify the quality,the theory of value engineering(VE) is used to found the time-cost-quality optimization model.

A conception of mass coefficient was put forward to simplify cool consumption calculations of exterior protected construction.

The mass coefficient was brought forward to assess the activity factor of original coal gangue.

The concep- tion of mass coefficient was introduced to simplify heating consumption calculations of exterior protection construction.

According to the current situation of transmission and distribution sectors in China, and based on the existing research results and the prevailing tariff regulation methods in the world, this paper proposes a refined price cap regulation model which takes the environment-related factor and the power quality factor into consideration.

Test results show that the freeze thaw durability and strength of GGBS concrete are greatly affected by the strength grade,curing regime and GGBS replacement level.
