Results from whole-cell patch clamp showed: 1 BmK Ⅰ(α-like neurotoxin) was found to prolong the duration of action potential and promote the amplitude of action potential. The effects could be attributed to the selective action of BmK Ⅰ on the TTX-S Na〓 channel: slowing the inactivation process of Na〓 channel, increasing the amplitude of peak Na〓 currents; 2 BmK abT, a new-type neurotoxin with higher sequence homology to β-type scorpion neurotoxin, was found to slow the inactivation process of Na〓 channel and prolong the duration of action potential in DRG neurons.

全细胞膜片钳研究发现：1）类α型哺乳动物毒素BmK Ⅰ可延长部分DRG神经元全细胞动作电位的时程，增加动作电位的幅度，这些效应可归咎于BmK Ⅰ选择性地作用于DRG神经元TTX—S钠通道，延缓TTX—S钠电流的失活化相，峰钠电流幅度增加；2）BmK abT，一个与β型毒素同源性较高的新型蝎毒素可抑制DRG神经元全细胞钠电流失活化过程，使动作电位时程增加。

Then through dynamical analysis, every instantaneous acceleration distributing of slope under dynamical earthquake can be got too. According to this result, adding earthquake force to structure by way of inertial force, this paper analyses the slope stabilization by using FEM strength reduction method and gains every instantaneous safety factor and its corresponding slide. Curves of safety factors versus duration can be made by curvefitting. By safety factors versus duration curves and slides, we can value structure's quakeproof stabilization and point its slide out. By these principles, programs of FEM stabilization analysis for each moment are organized.
