It is concerned with the material characteristics of ice, containing material nonlinearity, geometric nonlinearity and nonlinear boundary conditions, and other uncertain factors, which make it difficult to calculate the collision force precisely.
To save the calculation time, the concrete of pier adopted linear elastic material model.

A Study of Antioxidant Activity About Seleno-polysaccharide of Cordyceps militaris from different areas of China Qin Li1,a Chi Zhang2,b 1School of Biological Science and Technology,Hubei Institute for Nationalities, Enshi 445000,Hubei,People/s Republic of China 2School of Biological Science and Technology,Hubei Institute for Nationalities, Key Laboratory of Biologic Resources Protection and Utilization of Hubei Province , Enshi,Hubei,445000,People/s Republic of China a email,1342260627@qq.com,b correspondence email ,zhtzu@163.com Keywords:Cordyceps militaris; seleno-polysaccharide;reducing power;superoxide anion radical;hydroxyl radical Abstract.In this article,Cordyceps militaris,that from Hubei and Yunnan,were used as the research objects, to extract seleno-polysaccharide ,then the antioxidant activity of seleno-polysaccharide were determined by reducing power,the scavenging capacity on superoxide anion radical and hydroxyl radical.The results indicated that,the content of
Research materials, reagents and equipment Materials.Two kinds of Cordyceps militaris fruiting body respectively from Yunnan and Hubei.
So the processing condition would be taken into account in the further research or production.Try to reduce the damage to the active materials under mild conditions to process,it really reflected the efficacy of commercial Se-rich Cordyceps militaris.

Utilization of mining slag varies with its treatment, with water slag mainly used in the production of cement and concrete and dry slag mainly as surfacing materials.
Steel slag Steel slag originates from oxidizers caused by the oxidization of various elements in the process of steel smelting and other smelting materials, whose release rate is 15-20% of the total raw steel.
Nowadays, Steel slag can be used as raw materials for cement, surfacing materials in the place of stone pieces and phosphate fertilizer.
