某小型公司有四类人员：总经理、技术人员、销售经理、推销员。设计一个基类Person，并派生出Employee（职员）(A small company has four categories of personnel: general manager, technical staff, sales manager, salesman)

有关MATLAB的技术手册，可以方便大家查阅学习软件(about matlab handbook)

地质统计学中——实验变差函数的计算，对于空间分析很有帮助！(The experiment becomes poor function of computation)

常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)

API的英文全称(ApplicationProgrammingInterface)，WIN32API也就是MicrosoftWindows32位平台的应用程序编程接口。(API s English name (ApplicationProgrammingInterface), WIN32API is MicrosoftWindows32 platform application programming interface.)

利用遗传算法解决电力系统最优潮流问题。程序opf1为最优潮流的模型建立部分，gaopf是主函数，求解最小燃料费用。(By using the genetic algorithm to solve the power system optimal power flow problem.Program opf1 for optimal power flow model is established in this part, gaopf is the main function, and solving the minimum fuel costs.)

说明：  对被噪声污染的灰度图像进行滤波，是一种自适应滤波器。(denoiseing for the gray scale image)

说明：  波束图定义为当阵列输入为平面波时，阵列输出与平面波入射角的关系。阵列天线的方向图是全方向的，但阵列的输出经过加权求和后，却可以使阵列接受的方向增益聚集在一个方向上，相当于形成一个波束，(The wave beam chart defines to work as when array input for plane wave, array output and plane wave incidence angle relations. Array antennas s directional diagram is entire direction, but array output after weighting summation, actually may cause the directive gain which the array accepts to gather in a direction, is equal in forms wave beam, )
