不能克服

Considering the effect of the angle of internal friction on the inclination of sliding plane of soils behind retaining wall, circular and catenary, the two shapes of minor principal stress arch are theoretically analyzed. According to the shapes of minor principal stress arch, the coefficients of earth pressure corresponding to different angle of internal friction and that of wall friction are gained.

为克服现有考虑土拱效应的土压力计算方法不能考虑墙土摩擦角变化对挡土墙后土体滑裂面的影响的不足，考虑墙土摩擦角变化对挡土墙后上体滑裂面倾角的影响，对圆弧和悬链线两种拱形分别进行了分析，并与现有方法计算结果进行了比较。

The conditional nonlinear optimal perturbation is a new theoretical method proposed by Mu,et al in 2003, which is an extension of the linear singular vector to nonlinear regimes. It has become a powerful tool to study some issues of nonlinear systems like predictability, sensitivity and so on, because it overcomes the defect of LSV for not representing the fastest developing perturbation of a nonlinear system.

Enzyme as a biological catalyst is very sensitive to the environment , physical, chemical and biological factors.In the other hand it is difficult to purify from the reaction products. What's more it can not make a continuous operation.All those astrict the reaction.Under this condition, enzyme immobilization was put forward and developed.

酶作为一种生物催化剂，对环境十分敏感，易受物理、化学和生物等因素的影响而失活，而且反应后混入产品，纯化困难，不能实现连续操作，这些难以克服的现象大大限制了酶促反应在工业中的应用，在这种条件下，固定化酶的概念和技术得以提出和发展。
