At the same time,a tension stress is applied on theγ′phase interfaces along the direction parallel to the stress axis,which results in the lattice expansion ofγ′phase to trap the Al,Ta atoms with the bigger radius.This brings out the accumulation of the solute atoms to form the N-type rafted structure.Al,Ta atoms with bigger radius diffuse to the {100} plane to form the linked bond of the heterogeneous atoms and the stable stacking mode,this is a main reason of promoting the transformation ofγ′phase into the N-type rafted structure.And the change of the strain energy density in different interfaces of the cubical-likeγ′phase is thought to be the driving force of the elements diffusion and theγ′phase directional growth during creep.

拉伸蠕变期间，类立方γ\'相中与施加应力轴垂直的界面受水平切应力，使晶格收缩可排斥较大半径的Al、Ta原子；与应力轴平行的界面受拉伸张应力，使晶格扩张可诱捕较大半径的Al、Ta原子，由此引起的原子偏聚形成γ\'相是自由能降低的过程；其中，较大半径的Al、Ta原子扩散迁移至{100}晶面，形成异类原子结合键及稳定的堆垛方式，是促使γ\'相形成N-型筏状结构的主要原因；而γ\'相不同界面的应变能密度变化是元素扩散及γ\'相定向粗化的驱动力。

Four substances including 2-methyl ethyl acetoacetate and barley straw extract distilled from bulrush as well as cetyl trimethyl ammonium bromide and isothiazo lintone were used for the comparison experiment in inhibiting the growth of Microcystis aeruginosa in various phases. Result showed that inputting chemicals in the lag phase has better effect than in the log phase, and adding in lag phase can effectively inhibit the algae growth. Although feeding allelopathic substance at log phase can lead to certain restraining effect, it cannot result in the effective inhibition of algae growth, which can be well achieved by feeding CTAB and isothiazo lintone below 10mgl/L during log phase.

由于对断相运行给电机造成的危害认识不同，因此在对电机实行断相保护时产生了两种不同的意见：认为断相给电机造成过热损坏的观点要对电机实行过热保护或过流反时限特性保护，由此产生了热继电器方案、热敏电阻方案、断相过流延时保护方案以及其他一些方案；认为断相给电机绕组造成高压反电势击穿的观点，对断相采取瞬时动作保护方案，于是一些电子式保护器问世。

The morphology and structure of reconstructed tissue was detected by microscope and scanning electron microscope.Results:(1) Compared with the control group, the cellular proportion of laminin group increased in 62 ~M phase, and decreased in Go~Gi phase significantly. As shown by the microscope, the cells of control group were in low density. The cells in mass connected tightly. The microfilament appeared reticular formation. The nucleus were the same in size. The cells of laminin group were in high density and put out so many lamellipodia, filopodia, which connected with the surrounding cells. The microfilament increased, elongated, and changed from reticulodromous to sarciniform, which reached to the pseudopods. The nucleus were different in size .(2) As shown by the inverted microscope and the cell growth curve, comparing with the controlgroup, cells of each test group increased evidently. The cellular proportion of each test group increased in S phase and G2 ~M phase, and decreased in Go~Gi phase significantly, but there was no considerable interations between LN and EGF;(3) As shown by the morphological observations, the cultured cat corneal endothelial cells formed an integrated membrane, and attached to the Descemets membrane closely, which was similar to the natural tissue. The cells connected tightly to each other, and some of them arranged in hexagon approximately.
