可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

this file draw the nyquist diagram of multi input- multi output systems that they are such important kind of systems in control systems

说明：  利用ncl程序绘制eof分析的图，为大气从业或就学者提供参考。(Using the NCL program to draw the EOF analysis diagram, provide reference for the atmospheric practitioners or scholars.)

AUTO CAD 2013破解程序，非常好用，使用多次均能成功。(AUTO CAD 2013 crack program)

C# 两条曲线 实时显示 zedgraph(C# two curves displayed in real time)

一个简单的程序，可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行，而没有在paint方法里进行，可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)

cad中可以像cass一样划线,具有换向，隔点闭合等功能！(cad cass huaxian)

C#的画图控件，包括柱状图，饼图，线图。支持快速缩放。(C#, drawing control, including bar charts, pie chart, line graph. Support rapid scaling.)

对三维融合后的图像进行质量评价，其中包括信息熵、平均梯度、标准差、空间频率、均方根误差、峰值信噪比 (The three-dimensional fusion of the image quality uation, including information entropy, the average gradient, standard deviation, spatial frequency, root mean square error, peak signal to noise ratio)

在前人工作的基础上对三层层状介质的瑞利波频散曲线进行了正演模拟研究，对假定的几组典型模型参数的频散曲线进行了认真分析。通过分析可知，各频散曲线之间是互不相交的，从而对此问题有了一个更清晰的认识。指出当低速软弱夹层存在时频散曲线的特点，并根据分析结果，说明”之“字形频散曲线的形成机理。(On the basis of previous work, the Rayleigh wave dispersion curves of three layered media are studied by forward simulation, and the dispersion curves of some assumed typical model parameters are carefully analyzed. Through the analysis, we can see that the dispersion curves are not intersected with each other, so we have a clearer understanding of this problem. It is pointed out that the characteristic of time dispersion curve exists in low-speed weak interlayer, and according to the analysis results, the formation mechanism of zigzag dispersion curve is explained.)
