用VB做的一个摄影测量的单向空间交会程序 相比VC虽然没有这么简洁，但是很有启发性(Using VB to do a photogrammetric procedure compared with one-way space rendezvous VC Although there is no such simple, but very instructive)

根据Lennard-Jones 分子相互作用模型，利用计算机数值模拟方法，对一定空间内有 限粒子的运动情况进行模拟，分析粒子的运动位置、速度分布(According to Lennard-Jones molecular interaction model, the use of computer simulation methods, for certain limited space to simulate the movement of particles, particle motion analysis of position, velocity distribution)

本程序实现了自动检测远程或本地主机安全性，发现远程服务器的各种TCP端口的分配及提供的服务。-the program automatically detects the remote or local host security, found the remote server TCP port allocation and provision of services.

说明：  仿真一个4QAM信号通过莱斯因子为2的随机衰落信道和AWGN信道的过程，计算不同信噪比下的误码率。在Visual Studio下使用IT++仿真。(A 4QAM signal passes through the random fading channel with rice factor 2 and AWGN channel to calculate the bit error rate under different SNR. Itpp emulation.)

网络编程中经常要用到的对ip地址＆端口的扫描，此例程提供了一种端口扫描方法-network programming to the regular use of the ip address & port scan, the routines provide a port scan methods

说明：  一个简单的用Android编写的弹出框程序，适合初学者(Android Programming, Android Initial Architecture, Android Developers Necessary)

用来检测内存泄露，只要添加到VC里面就可以了，有txt文件说明(Used to detect memory leaks, added to the VC inside the txt file)

五种飞行轨迹，轨迹中包含各种飞行姿态，适合初学者。(Five Kinds of Flight Trajectories)
