用遗传算法解决TSP模型，为了增加效率，采用了改良圈法初始化种群，效果很好，而且还有模拟结果图像，值得一看！(Using genetic algorithms to solve the TSP model, in order to increase efficiency, using a modified micro-metering initialization population, the effect is very good, but also the simulation results image and worth a look! )

This programm is to calculate a two dimentional conduction problem.

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)
