Through above study, the theoretical analysis of the inherent fault tolerance of feed-forward neural networks has been extended from hard-limit activation functions to differentiable activation functions; 2. By using above method, fault tolerance of discrete Hopfield feedback neural networks have been also analyzed. It means that the above method can be applied not only for feed-forward neural networks but also for feedback neural networks; 3. For the feed-forward neural network with the Sigmoid activation function, Chebyshev Inequality method was presented.

Forty-eight hours after transfection, cells were harvested to determine luciferase activity by illuminometer. In the presence of RU486 a 40-fold maximum activation of the luciferase reporter gene was observed in cultured cells, whereas in the absence of RU486, no significant activation was observed. There was a positive correlation between the luciferase activation and RU486 concentration in a definite range. The results showed that the RU486-inducible regulatory vector was successfully constructed, which can be used to regulate the expression level of genes of interest in appropriate time by the inducer RU486. This inducible expression vector provides a platform for the research of gene regulation and gene therapy.

加入诱导剂RU486后，可以诱导表达荧光素酶，并在一定范围内两者呈正比，最高可以实现荧光素酶的40余倍的表达，而没有RU486时，几乎没有报告基因的表达，表明RU486诱导调控载体构建成功，可实现对目的基因的表达时间和表达水平的精确调控，为进一步的基因调控研究和和基因治疗提供了良好的工具。

Results In all 12 normal children, the blood oxygen level-dependent signal was negative, and the maximum response appeared to be located in the anterior and superior part of the calcarine fissure, which may correspond to the anterior region of the primary visual cortex.

In the experiment section, there"re three experiments investigating implicit attitude and dual-attitude model. In the first experiment, the author studies the effects of attitude strengthen on attitude"s automatic activation effect. In the second experiment , the author studies the effect of delay condition on the attitude"s automatic activation effect. Delay condition make experiment approach to mere exposure of attitude object, and two experiment demonstrate attitude"s automatic activation effect is the result of noncognitive processing.

第一个实验，探讨了态度强度对态度自动激活效应范式的影响，结果发现态度强度不是影响态度自动激活效应的因素；在第二个实验中，探讨了时距对态度自动激活效应的影响，时距控制使得实验更接近于态度物的单纯呈现，结果发现时距没有对自动态度激活效应产生影响，从而论证自动态度激活效应可能是非认知系统作用的结果，具有普遍性。

This experiment aimed to systematically investigate and analyze the ethanol activated rates of mouse oocytes, affected factors of oocytes activation, types and development of parthenotes, and the organization and roles of the cytoskeleton during pronuclear formation and migration and early embryo cleavage by ethanol activation of oocytes, embryo culture in vitro and immunofluorescence cyto-chemistry. The results:(1) The ethanol activation of mouse oocytes showed that the activated and developmental rates of oocytes increased significantly with the increase of ethanol concentration and extension of exposure time, but over concentration and exposure time would result in increased fragment rates significantly. 7% ethanol treated oocytes for 7min was the optimum activated condition.
