用于abaqus粘弹性材料的计算模拟及验证(Computational simulation and verification of ABAQUS viscoelastic materials)

用matlab对Buck电路进行了仿真,简单直接可用，BUCK电路就是一种DC-DC转换器，简单的讲就是通过震荡电路将一直流电压转变为一高频电源，然后通过脉冲变压器、整流滤波回路输出需要的直流电压，类似于开关电源(The BUCK circuit is a kind of DC-DC converter, which is simply to convert a DC voltage to a high frequency power supply through a concussion circuit, and then output the required DC voltage through a pulse transformer and a rectifier filter circuit, similar to a switching power supply.)

说明：  MFC实现滑动窗口协议是一个基于对话框的程序来模拟协议工作过程及原理，分发送端和接收端，开始时设置发送窗口和接收窗口及重传计时器等相关参数，点击开始发送即可开始模拟数据发送过程。设置出错帧时，可以随机产生错误帧，也可以手动指定错误帧。(The sliding window protocol implemented by MFC is a dialog-based program to simulate the working process and principle of the protocol, distribute the sender and receiver, set the relevant parameters such as sending window, receiving window and retransmit timer at the beginning, and then start to simulate the data transmission process by clicking on the start of sending. When an error frame is set, the error frame can be generated randomly, or the error frame can be specified manually.)

利用V.Mise屈服准则和粘塑性方法来分析平面应变问题，以此为基础以后还可能扩展到轴对称问题(V. Mise yield criterion and the use of visco-plastic approach to the analysis of plane strain problems, as a basis for the future may also be extended to axisymmetric problems)
