摘要:
目的：在电场作用下，多细胞相对位置对电场应力分布的影响。方法：对于单细胞，通过求解满足边界条件的拉普拉斯方程，对于多细胞利用电磁场仿真软件ANSYS-Maxwell求解细胞内外电场分布。用麦克斯韦应力张量法分析细胞电场应力分布。结果：与单个细胞相比，电场作用于3个细胞时，细胞表面电场应力分布仍具有一定的对称性，细胞间距变化时，细胞间感应强度也相应发生变化。在细胞间距足够大的情况下，各细胞间的相互影响非常小，可以将其近似为单细胞模型处理。结论：细胞数目和细胞间距都会影响细胞表面电场应力的分布情况，细胞在电场作用下发生的形变与细胞表面所受电场应力有关。
Abstract:
Abstract: Objective To study the effect of the relative positions among multiple cells on electric field stress distribution under electric field. Methods The electric field distributions both inside and outside a single cell were obtained by solving the Laplace equations that satisfied the boundary conditions, while those of multiple cells were obtained by electric field simulation software ANSYS-Maxwell. The corresponding electric field stress distribution was analyzed using Maxwell stress tensor method. Results The distribution of electric field stress on the cell surface had certain symmetry for 3-cell system, compared with that of a single cell. The induction intensity between cells changed with cell spacing. When the cell spacing was large enough, the interaction between cells turned negligible, and it could be approximated as a single cell model. Conclusion The distribution of electric field stress on the cell surface is affected by the number and spacing of cells. The cell deformation under electric field is related to the electric field stress on the cell surface.
