文摘:通过求解电势的拉普拉斯方程，讨论组合圆柱面电容中的电势、电荷和电容 - There are many kinds of ways to solve the electrostatic field of two - dimensional laplace ’ s equation or the poisson ' s equation , like the separation of variables , green ’ s function or alternative means . but if their boundary shapes are quite complex , it is extremely difficult to use these usual methods , and , in general , it is impossible to work out even there is such peculiar instance as analytic solution , or obtains the approximate solution
对二维拉普拉斯方程或泊松方程的平面场的解法有多种,如分离变量法、格林函数法或者其他方法,但如果它们的边界形状比较复杂,用这些通常的方法求解会非常困难,即使对于存在有解析解的特殊情况,一般说来也不可能求出,而且求得的只能是近似解。 - Review of linear algebra , applications to networks , structures , and estimation , lagrange multipliers , differential equations of equilibrium , laplace ' s equation and potential flow , boundary - value problems , minimum principles and calculus of variations , fourier series , discrete fourier transform , convolution , applications

采用经验公式来计算三偏心蝶阀的动水力矩，误差比较大，本文根据三偏心蝶阀的结构特点，利用理想流体的定常、无旋流动的假定，用有限差分法在直角坐标系中求解拉普拉斯方程，得到蝶板截面上的压力分布，从而计算出蝶板在各个开度下的动水力矩，设计出了求解的程序，给出了程序运行的结果并进行了数据处理从而得到了动水力矩曲线，总结了它的变化规律。
