PWM模型，用于电力电子模型中电子器件控制的PWM脉冲模块的使用。(The PWM model is used for the PWM pulse module controlled by electronic devices in the power electronic model.)

It can store company pictures, office documents, Autocad drawings and other information. System data are stored in the database, when users upload, update or overwrite, by default, automatic backup will be carried out to prevent data loss.

求解二维热传导方程，文档中有过程和matlab程序。 本文利用有限差分法来求二维热传导方程的数值解，通过Matlab编程求解并作图，进而与解析 解做出的图进行比较，画出误差图。(Solving the two-dimensional heat conduction equation, there are procedures and MATLAB programs in the document. In this paper, the finite difference method is used to find the numerical solution of the two-dimensional heat conduction equation, and is solved and plotted by Matlab programming. The diagram made by the solution is compared, and the error map is drawn.)

对哔哩哔哩弹幕进行抽取并完成情感倾向的分析和估计(To extract bilibili barrage and complete the analysis and estimation of emotional tendency)

说明：  在esp32上使用ds1302时钟模块，此程序主要使用正点原子stm32程序移植得到(Using DS1302 on esp32)

说明：  这是个关于bpsk载波恢复的例子，我们用simulik来搭建的整个系统，非常有利于对调制解调和载波恢复的理解。(This is a carrier recovery on the bpsk example, we use simulik to build the entire system, very beneficial for modulation and demodulation and carrier recovery understanding.)
