Due to the poor thermal conductivity of concrete materials, leading to the concrete structure in the solar radiation, the effect of sudden temperature drop, the structure of the surface temperature change, however, the most region of internal structure remains the original state of the temperature, so that the temperature gradient appears.
In domestic, concrete box-girder temperature field experimental the first study was researched by Ministry of Railways academy of sciences southwest.
Fig.3 The finite element model The sensitivity analysis under the overall heating and cooling With reference to the local weather bureau of material, YouXian perennial average temperature is 17.8℃, the highest temperature is 40.5℃, the minimum temperature is 4℃.

By overloading or reducing material strength, the limit equilibrium state of arch dam foundation system is judged with convergence criterion or abrupt change criterion [2], and multiples of overloading or of material strength reduction is the global safety factor of arch dam foundation system.
Dam concrete and foundation rock are simulated as perfect elasto-plastic material with Drucker-Prager yield criterion.

A study on the Photolysis Behavior of Photoacid Generators Weimin ZHANG1,a, Wenguang WANG2,b, Jialing PU3,c (Beijing Area Major Lab of Printing & Packaging Material and Technology, Beijing Institute of Graphic Communication, Beijing 102600) zhangweimin@bigc.edu.cn, wangwenguang@bigc.edu.cn, pujialing@bigc.edu.cn Key Words：photoacid generator, photolysis; acid generating efficiency Abstract.
If added the acid proliferation generator (APG) in the imaging system, it was can be get more acid production efficiency, and higher chemical amplified, high-sensitivity imaging material system.
Therefore, it is important to quantitatively evaluate the acid yield of PAG and provide decisive information to the design of PAG and the related material system.
