说明：  ahp层次分析，一个简单的实例来诠释ahp的整个过程，完全符合整个开发流程。(ahp-level analysis, a simple example to explain the whole process of ahp entirely consistent with the overall development process.)

模拟雷达，对雷达的功能进行分析，可以根据对参数的修改方便地看到输出的图形结果(simulated radar, the radar functional analysis Based on parameters can be amended easily see the graphics output results)

本例用五点差分法求解一个二阶偏微分方程，其间用SSOR预处理的CG法处理，此实验可分别选取N=4，8，16，32(This example uses a five-point difference method for solving second order partial differential equations, during which the CG with SSOR pre-treatment, were selected for this experiment can be N = 4,8,16,32)

说明：  扩频通信中的两大常见扩频方式，直接序列扩频和跳频(Direct sequence spread spectrum and frequency hopping are two common spread spectrum methods in spread spectrum communication)
