静电

In static analysis, small deflection theory of circular plate and electrostatic actuating theory are adopted to simulate electrostatic-structural coupled process. In modal analysis, harmonic response analysis and nonlinear transient dynamic analysis of pump membrane, the fluid in the pump is regarded as an additional mass acting on the pump membrane to approximately substitute the effect of fluid field on pump membrane, which reduces the amount of calculation and improves simulation efficiency.

其中在静态分析中，利用圆型薄板的小挠度变形理论和微机电系统中的静电力驱动理论来模拟静电－结构耦合过程；在泵膜的模态分析、谐响应分析以及非线性瞬态分析中，把腔内的流体当作附加质量作用在泵膜上，近似代替流场对泵膜的影响，从而减小计算量，提高了仿真效率。

Since the dismutation of superoxide radicals by SOD is a reaction that is rate-limited by diffusion and enhanced by electrostatic guidance, all these structural features may be related to GP-MnSOD's high catalytic activity: first, Lys38 may increase the effective enzyme-substrate association rate by enhancing the electrostatic gradient at its substrate channel; second, an excess of acidic over basic residues makes the negative surface potential of GP-MnSOD more larger than those of other known MnSODs. This may enhance the reaction rate by reducing futile collisions of superoxide radicals with GP-MnSOD's surface.

因此，GP-MnSOD的上述结构特征可能与GP-MnSOD的较高酶活有关：首先，Lys38增加了底物通道口的正静电势梯度，从而可能促进了GP-MnSOD的活性中心与底物的有效结合速率；其次，GP-MnSOD表面覆盖的过量酸性残基使得它比其它MnSOD在底物通道以外的蛋白表面更多地被负静电势所覆盖，这可能有效地减少了超氧阴离子与GP-MnSOD表面的无效碰撞，从而提高了反应速率。

刮板制卡和会员卡制作的速度降低，原子核周围的电子云处于相对稳定的状态，但是即使制卡和会员卡制作速度变慢，刮板压力过大时，原子核周围的电子也会处于不稳定状态，电子会在刮板压力下游离出来，产生静电，因此，只有当刮板制卡和会员卡制作速度慢，同时刮板压力适合的情况下，才能避免静电的产生。
