说明：  步进电机正反转调速系统设计，使用51单片机(Design of forward reverse speed adjustment system for stepping motor)

实现ARQ协议的简单模拟，包括发送，确认号，等待，出错重发等等。(Realise a simple Model as ARQ Protocol)

C语言的配套学习课件 适合计算机专业学生(C Programming Language supporting courseware)

说明：  直接通过ODBC读写Excel表格文件。基于数据库编写源程序。(Directly through ODBC to read and write Excel spreadsheet file. Prepared based on the source database.)

此工具支持国密各种算法：SM4对称加解密，国密密钥对的生成，SM3信息摘要，SM2数字签名以及验证签名，SM2非对称加解密，PKCS7签名数据包形成以及PKCS7验签， 生成PKCS7数字信封已经解PKCS7签名数据，后续会添加PKCS7签名数字信封相关功能。输入输出格式都严格按照国家密码管理局的相关规定。形成一个本地工具方便大家使用。(This tool supports various national algorithms: SM4 symmetric encryption and decryption, national secret key pair generation, SM3 information summary, SM2 digital signature and verification signature, SM2 asymmetric encryption and decryption, PKCS7 signature data packet formation and PKCS7 checkin, PKCS7 digital envelopes have already solved PKCS7 signature numbers, and then PKCS7 signature digital envelopes will be added. Related functions. The input and output formats are in strict accordance with the relevant regulations of the State Encryption administration. The formation of a local tool is convenient for everyone to use.)

说明：  linux中busybox的mesg的代码实现，源码(linux busybox mesg function)

这是一个用vc6.0写的数据库，里面有ado，dao，adb编程！(This is a database used vc6.0 write, there are ado, dao, adb programming!)

这是一个对于L2范数下的Earth Mover Distance的VC实现。(This is an L2 norm for the Earth Mover Distance realize the VC.)
