ChatClient
利用C++实现的一个即时通讯系统的客户端。传输层采用的是TCP协议。这是本科时候的毕业设计，最后评定为优，希望对一些朋友能有所帮助。(The use of C++ implementation of an instant messaging system client. Transport layer protocol used is TCP. This is the time of undergraduate graduation project, and finally classified as gifted, in the hope that some of my friends can be helpful.)

zemax源码：
This DLL models a standard ZEMAX surface type, either plane, sphere, or conic
The surface also demonstrates a user-defined apodization filter
The filter is defined as part of the real ray trace, case 5
The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y.
The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)]
The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)]
where
x^2 + y^2 = r^2
R = semi-diameter
The tranmitted intensity is maximum in the center.
T is set to 0 if semi-diameter < 1e-10 to avoid division by zero.

GSM
利用通讯模块进行数据通信，就是将数据体作为短消息的内容，从发送方的通讯模块发送出去，通过短消息中心进行转发，接收方通讯模块收到此短消息后即存储在SIM卡上，模块外接的控制器（如单片机、计算机等）从模块中读取短消息后，根据需要将无用的信息去除，取出有效信息，然后将SIM卡中的短消息删除，这样就完成一次单向数据的传输。利用通讯模块的短消息方式实现数据的发送和接收具有通信成本低、系统容量大、抗干扰能力强等优点，而且短消息经过服务中心再到达目的地的特点使通讯模块无需24小时开机，降低了系统功耗，特别适合遥控、遥测、远程信息处理和通信等领域。(GSM)
