2．3有限元素法与以前的解析方法比较上一次介绍了有限元素法的基本考虑方法和计算步骤。本节介绍有限元素法与以前的解析方法的比较。因为弄清有限元素法与以前所用的解析方法之同异，不但有助于理解有限元素法，而且根据所要解决的问题考虑选择最佳方法也是有益的。将以前用
2.3 Finite element method compared with the previous analytical methods Last introduced the basic considerations of finite element method and calculation steps. This section describes the comparison of the finite element method with the previous method of parsing. It is not only helpful to understand the finite element method but also to select the best method according to the problem to be solved because it is helpful to understand the same elements of the finite element method and the previous analytical methods. Will be used before
