In this paper, taking the downward continuation of potential field as an inverse problem of upward continuation, we obtain a convolution type linear integral equation for downward continuation. Making use of the orthogonal symmetry characteristic of Fourier transform matrix, and combining the principles of singular value decomposition of matrix and generalized inverse, we proposed a stable generalized inverse method for downward continuation of potential field, called wavenumber domain generalized inverse algorithm, which doesn't need the computation for inverse matrix. It resolves the instability of potential field downward continuation of large depth.

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。

The interatomic potential for Al-Mg alloys is different from the others used in the paper.

The control principle of electrostatic shaping was introduced according to the balance between electrostatic force and resulting force formed by membrane deformation and the complex shaping process of SMEC. Then, taking the trisection circularity electrode for an example, the distribution characteristic of electric potential in the electrostatic field was analyzed, namely, the expression of potential function in the electrostatic field was deduced by Laplacian equation. And then, by combining the difference equation with electric potential expression, the numerical solutions of electrostatic force in single electrode mode and trisection circularity electrode mode were disposed. Finally, the calculated figure was compared with the ideal paraboloid and comparison shows that more accuracy would be achieved by multi-electrode control.
