土方计算

还很好 -also very, very good very, very good

数据结构实验：实现两表达式算术求和 任务：能够按照指数降序排列建立并输出多项式； 能够完成两个多项式的相加、相减，并将结果输入； -experimental data structure : achieving two arithmetic expressions Summation tasks : According to index in descending order and the establishment of export polynomial; to complete the combined two polynomials, subtraction, and the results input;

对于通信时隙分配的ＴＤＭＡ仿真，对其ＭＡＣ协议进行了详细的模拟(TDMA slot allocation for the simulation of communication, its MAC protocol in detail the simulation)

北大群论讲义，作为老师讲的讲义，还算通俗易懂。(North group theory lectures, as teacher handouts, fairly easy to understand.)

目前国内唯一一本介绍通用变频器的书籍，各大变频器厂商都将其作为工作手册使用。对目前国内较缺的矢量变频器 高压变频器作了一般性介绍。对DSP电机控制有指导作用。(At present, only a general-purpose inverter, introduced books, major inverter manufacturers will use its position as the work manual. Than the current lack of domestic vector converter high voltage inverter a general introduction. DSP motor control of the guiding role.)

一个好看的界面，可以移植到pb的程序中使用-A nice interface, can be transplanted to the procedure used pb

作了个小程序，主要是为了验证将结构体存储到ini文件中去到底是怎么回事，没有弄明白的是为什么结构体中不能包含CString类-Made a small program, mainly in order to verify the structure stored in ini files in the end to how the matter is not understood why the structure can not contain CString Class

说明：  TRF7970A阅读器读卡模块参考设计，包含I2C接口源码和UART接口源码，包含硬件原理参考文档(Trf7970a reader card reading module reference design, including I2C interface source code and UART interface source code, including hardware principle reference document.)

说明：  鞍点问题 这是C语言中一个常见问题，此代码有助于更深的理解(This is a C language code about saddle point problem.)

唐山市用ARC做的地图矢量化，是进行系统开发的准备和前提条件。-Tangshan City to do with ARC map vectorization is to carry out system development and prepare a prerequisite.
