最后，探讨了三相孔隙介质的孔隙度和饱和程度对非连续分叉的影响。

Based on the theoretical analysis of the disturbance effect during vertical drain construction, in this paper, probability analysis is adopted, and the impact of variability of parameters with larger uncertainty or discreteness on consolidation reliablity is analyzed, which is very useful in the design and construction of soft clay ground treatment.

本文在理论分析竖井施工扰动效应的基础上，采用概率分析的手段，对由扰动效应引起的不确定性或离散性较大的参数，分析其变异性对固结可靠性的影响，对于饱和软黏土地基处理的设计和施工具有一定的指导意义。

Superoxide dismutases family are thought to be one of the first lines of antioxidant defense and are highly efficient in protecting cells and tissues against oxidative stress by catalyzing the dismutation of superoxide radicals to form hydrogen peroxide and molecular oxygen.

但由于活性氧分子反应的非特异性，它们也会破坏宿主机体细胞内的功能蛋白分子、不饱和脂肪酸分子和核酸等，对细胞造成严重的伤害，进而导致机体生理机能的损伤和免疫系统的破坏。

Then,the tradition manner of crystallization was evaporating and crystalline,but this paper made the other method . The salt-mixture solution of the disodium hydrogen phosphate and the monometallic odium orthophosphate was put in ethanol.

传统的结晶方法是通过加热蒸发结晶，而本文则采用了一种新的结晶方法，在精调后的正磷酸盐混合溶液中加入乙醇，由于正磷酸盐不溶于乙醇，就会使正磷酸盐溶液达到过饱和，再通过搅拌，析出晶体。

The microgels prepared by dispersion polymerization in polar medium can be used to improve the tensile strength of unsaturated polyester products.
