引言作为一个对于许多含水层反应问题进行分析的工具,数字模型曾代替了电拟模型。然而,电阻一电容模拟模型将继续应用,充当含水层发展中特殊目的的处理工具。在某些条件下,电拟模型还优越于数字模型。主要优点是:(i)它能够应用大量的网格,在这种情况下,数字模型也许需要过量的计算储存容量,太昂贵;(ii)它能够用于研究多层含水层,而有用的三向数字模型费用浩大;(iii)它还提供了在示波仪上直接观 INTRODUCTION As a tool for analyzing many aquifer response problems, the digital model replaced the electro- model. However, the resistance-capacitance simulation model will continue to be used as a processing tool for special purposes in the development of aquifers. Under certain conditions, the eigenmodel is also superior to the digital model. The main advantages are: (i) it is capable of applying a large number of grids, in which case the digital model may require excessive computational storage capacity, too expensive; (ii) it can be used to study multiple aquifers while useful The three-way digital model is costly; (iii) It also provides a direct view on the oscilloscope
