它将求解域看成是由许多称为有限元的小的互连子域组成，对每一单元假定一个合适的（较简单的）近似解，然后推导求解这个域总的满足条件（如结构的平衡条件），从而得到问题的解。(It regards the solution domain as consisting of many small interconnected subdomains called finite element elements, assumes a suitable (relatively simple) approximate solution for each element, and then deduces that the solution of this domain satisfies the conditions (such as the structural equilibrium condition), so as to obtain the solution of the problem.)

升压斩波电路（Boost）的仿真 针对 Boost 变换电路，完成以下工作： （1） 在 MATLAB/SIMULINK 下搭建 Buck 电路仿真模型，并设置好各个模块的参数； （2） 分别选择 3 个不同的占空比，用示波器同时观察 E，uGE，i1，io，uo 以及电感两 端的电压 uL和流过电容的电流 iL的波形（注意频率的选择）。(Boost simulation model is built under MATLAB / SIMULINK, and the parameters of each module are set up. (2) Choose three different duty cycles and simultaneously observe E, uGE, i1, io, uo and inductance with an oscilloscope.
