说明：  在dotnet平台下，用c#语言开发的类似foxmail换肤功能。(Under the dotnet platform, it is similar to Foxmail skin changing function developed by C #.)

1. SMPP网关概述（联系dotphoenix@qq.com获取更多信息） 1.1 包含一个标准的SMPP Server（SMPP模拟器），一个SMPP Client 和 SDK 1.2 支持标准的SMPP V3.4，支持如下功能：多种bind模式，unbind,submit_sm,delivery_sm,enquire_link,generic_ack 1.3 SMPP Server可运行于LinuxWindowsOSXEmbeded Linux 1.4 SMPP Client可运行于WindowsLinuxOSXAndroidiOSEmbeded Linux 1.5 SDK支持WindowsLinuxOSXAndroidiOSEmbeded Linux，可被JavaC#C++MFCPHP等调用，并提供基于json的HTTP API 1.6 支持MYSQL和SQLITE数据库 1.7 支持自定义计费，支持自定义业务系统 1.8 支持大吞吐量（使用数据库可支持500/秒，不使用数据库可支持8000条/秒) 1.9 兼容性良好，可以和几乎所有主流和非主流的网关及客户端正常工作( SMPP Gateway System（Contact dotphoenix@qq.com to get more information） 1 Including a standard SMPP Server（SMPP Simulator），a SMPP Client and SDK 2 Implement SMPP V3.4，Support PDUs including：3 bind modes，unbind,submit_sm,delivery_sm,enquire_link,generic_ack 3 SMPP Server supported platforms: LinuxWindowsOSXEmbeded Linux 4 SMPP Client supported platforms: WindowsLinuxOSXAndroidiOSEmbeded Linux 5 SDK supported platforms: WindowsLinuxOSXAndroidiOSEmbeded Linux，supported languages: JavaC#C++MFCPHP，and also including HTTP API based on JSON. 6 Suppored s: MYSQLSQLITE 7 Support customizing billing system and business system 8 Small delay, good reliability and large throughput (500 PDUs/s if need ，8000 PDUs/s if no need ) 9 Good compatibility, can co-work with nearly all the mainstream and non-mainstream gateways/servers/clients )

说明：  使用PT100传感器检测温度，然后控制风扇转动，达到降温的效果(Use PT100 sensor to detect temperature, and then control fan rotation to achieve cooling effect.)

计算地波传输衰减的程序,可以设置高度，大气条件等(Ground wave transmission attenuation calculation program, you can set the height, atmospheric conditions, etc.)

说明：  实现BPSK的载波同步，采用的方法是锁频环，最大似然法频率估计(BPSK carrier synchronization is realized,the method is frequency - locked loop and maximum likelihood frequency estimation)
