BCB 矢量绘图程序，具备 点、线、圆、文字 等基本图形，支持 复制、粘贴、等距排列等多种操作，图元的组合、拆分等已开发，放缩、存储等未完善，希望对广大BCB工作者有所帮助！(BCB vector drawing program, with points, lines, circles, text, and other basic graphics, support copy, paste, equally spaced and other operations, the combination of elements, split, etc. have been developed, zoom, storage, etc. are not perfect, I hope the majority of workers in BCB help!)

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.)

这是在MATLAB-2008a环境下编写的NURBS曲面生成程序，可以通过调整控制顶点和各个顶点的权重来调整曲面的形状。(This is a MATLAB-2008a environment, prepared by the NURBS surface generation program, you can adjust the control points and weights of all vertices to adjust the surface shape.)
