信号数据预处理程序，包括低通滤波，带通滤波(Signal data preprocessor：including a low pass filter, band-pass filter)

说明：  模型以永磁直驱同步发电机组为研究对象，对包括风力机、发电机及其控制系统等各部分进行控制建模与仿真，接着通过坐标变换，分析并网逆变器在d／q坐标系下的模型，采用基于d轴电网电压定向矢量控制，并通过前馈补偿，实现有功、无功的解藕独立控制.(The model takes the permanent magnet direct drive synchronous generator set as the research object, and carries on the control modeling and simulation to each part, including wind turbine, generator and its control system, and then analyzes the model of grid-connected inverter in d coordinate system through coordinate transformation. The voltage oriented vector control based on d-axis power network and feedforward compensation are adopted to realize the decoupling independent control of active and reactive power.)

说明：  进行多目标优化，主要是使用了NSGA-2的算法，在代码中进行了必要的标注(In the process of multi-objective optimization, nsga-2 algorithm is mainly used and necessary annotation is made in the code)

用R/S估算法计算时间序列的HURST指数(With R/S method to estimate time series HURST index)

求小圆柱波浪力，主要是波浪理论里面的狭长小圆柱体求解片段(wave force)

可在Matlab上阅读地震数据SEGY格式，并进行编辑(reading on the seismic data in Matlab SEGY format, and edit)

空间直角坐标（XYZ）和大地坐标（BLH）相互转换matlab函数(Space Cartesian coordinates (XYZ) and geodetic coordinates (BLH) conversion matlab function)

作为MATLAB的一个重要组成部分，Simulink由于它所具有的上述的两大功能和特色，以及所提供的可视化仿真环境、快捷简便的操作方法，而使其成为目前最受欢迎的仿真软件。 本章主要介绍Simulink的基本功能和基本操作方法，并通过举例介绍如何利用Simulink进行系统建模和仿真。 (As an important component of MATLAB, Simulink because it has the two above-mentioned functions and features, as well as provide visual simulation environment, quick and easy methods of operation, which makes it the most popular simulation software. This chapter introduces the basic functions of Simulink and basic operation methods, and through examples of how to use Simulink for system modeling and simulation.)

说明：  在新材料制备过程中，会遇到大贡的实脸数据需要处理的问题，利用visualBasic6.0调用Matlab可解 决这一问题。介绍了基本原理，执行办法，以及曲线拟合的理论方法，并给出了实现的程序和编制软件的部分界面。 (Abstract The preparation process of the new materials will meet the real face great tribute to deal with the problem of data, using visualBasic6.0 call Matlab solve this problem. Introduced the basic principles, implementation, and the theoretical curve fitting method, and gives the implementation process and the preparation of some of the software interface.)

说明：  利用C#创建窗体，通过设置按钮，同时利用按钮实现各种功能。此代码实现的功能是1、调用函数；2、显示照片，同时还能消除照片；3、通过调用MATLAB，实现图像显示的函数。(Use C# to create a form, by setting the button using the button at the same time to achieve various functions. This code implements the function is 1, call the function 2, display photos, while eliminating photographs 3, by calling MATLAB, the function of image display.)
