In the second part, the theory of numerical simulation is introduced, including description of body configuration, elastic-plastic large deformation constitutive equation and finite element formula. It is followed by the derivation of equation from the basic theory of elastic-plastic deformation. The solution to temperature field, thermal stress, thermal strain, equivalent effective stress and equivalent strain is achieved then. In addition, we exposit the relation between machine load and thermal load in coupling analysis.

Results. Semiquantitative assessment of histologic changes indicated that 4-week-old rabbit was equivalent to fetus to 2-year-old human and 160-week-old rabbit was equivalent to 11- to 30-year-old human, particularly 11- to 16-year-old, which corresponds to transition period from notochordal to fibrocartilaginous NP.

Regarding the equivalent educational qualifications examinee , in the exams for postgraduate schools process the policy type hard stipulation is together the insurmountable wall , for many years has been ambitious innumerably self enhancement outstanding equivalent educational qualifications crowd heartless blocking in the wrong side of the door .

对于同等学力考生来说，考研过程中政策性的硬规定是一道不可逾越的墙，多年来把无数有志自我提高的优秀同等学力人群无情的拦在了门外。

However, such tidal overheight is often ignored in the current regional numerical simulation due to intensive computational requirement. Only the mean sea level is used as the fixed seaward boundary, which may wrongly predict the groundwater table position. Therefore, we aim to determine an equivalent seaward boundary through numerical modeling. The equivalent seaward boundary takes into account the tide-induced overheight effects.
