根据7针状电极系上的电势,利用边界元积分方程建立以针状电极系线电荷密度为未知量的离散方程,通过求解线性方程组计算针状电极系上线电荷的不均匀分布.由针状电极系上的不均匀线电荷分布计算真空状态下空间任意一点的电势分布,实现了由边界元法对7针状电极系场分布的数值计算.

According to the electric potential on the seven-needle electrodes in vacuum, the discrete equations based on the indeterminate linear charge density (LCD) are established by the boundary element integral equations. The non-uniform distributions of LCD on the needle electrodes are calculated through solving a set of linear equations. With the help of the LCD, the potential and the electric field intensity generated by the multi-needle electrodes at any point in vacuum have been obtained. In this paper, we have realized the numerical calculation of the static field distributions for multi-needle electrode system by the boundary element approach.
