企业档案管理系统 概要设计说明书 需自行转化为doc文件(enterprise file management system outlined the need to design brochures into doc documents)

海力士 DDR2 操作手册，时序说明，很强大，适合初学者(ddr2 Operation Manual)

关于chirp信号的频率估计和定时估计的论文，对研究chirp信号有一定的帮助(About the frequency of the chirp signal estimation and timing estimation of thesis, has the certain help to the study of chirp signal)

在Microsoft Visual C++软件环境下，用C++ 语言实现整个仿真。将整个产生系统分为C/A码产生，信号产生，量化三个模块，经过编写和调制实现产生的基本功能，即输入导航电文及控制数据，例如 选取卫星信号，多 普勒频移，采样周期。最后可以得到加入服从高斯分布的噪声信号的数字离散中频信号。 (We use the C++ language to archive the simulation in the Microsoft Visual C++ circumstance. The entire generating system is divided into three parts,including C/A Code, Signal Generating and Quantizer. After writing codes and checking and confirming, I archive the basic functions. If you input the guiding codes and controldata like satellite selecting signal, Doppler frequency movement, sampling period, at last you can get the digital middle frequency signals with gauss distributing noise)

图书管理系统 一些基本的功能： 1：添加图书以及图书编号 2：能够实行基本的借书还还书的功能。 3： 删除图书信息等 (Some of the basic functions of the library management system: a: ​ ​ Add Books and Book Number 2: the ability to implement basic library book functions. 3: Remove the book information)

这是有关于stm32中的实验板子上的原理图，如果大家认真学习的话，肯定会了解stm32的(This is the experiment on the stm32 schematic diagram on the board, if you carefully study, you will certainly understand stm32 the)

This is the program for 2D ADI FDTD method introduced by Namiki. This works fine with non-uniform cell, but for uniform cells, the program is not correct.

guideline design PCB layout to reduce noise

较详细的论述了IPM模块的驱动及保护电路 (More detailed discussion of the IPM module driver and protection circuits)

说明：  SD卡的SPI方式驱动，SPI方式简单速度也可以，很多处理器都有SPI功能，没有也可模拟。(SD card SPI mode driver, SPI is simple speed can, many processors have the SPI function, does not and can simulate.)
