一、前言电模拟装置又称电模型,或称电模拟计算机。电模拟方法得以应用的前提在于不同物理现象用同一数学形式(如微分方程、积分方程等)描述。本文所介绍的解抛物型偏微分方程定解问题的电模拟方法不仅可解不稳定渗流问题,而且还可以解邻近物理领域中诸如热传导、质点的聚集或扩散、高频电流的集肤效
I. Introduction The electric simulation device is also called the electric model or electric analog computer. The premise of applying the electric simulation method is that different physical phenomena are described in the same mathematical form (such as differential equations, integral equations, etc.). The electrical simulation method for solving the definite solution problem of the partial differential equations for solving parabolic equations introduced in this paper not only solves the problem of unstable percolation, but also solves the effects of near-physics such as heat conduction, aggregation or diffusion of particles, and the skin effect of high-frequency currents.
