铺画列车运行图，可以参考一下如何画线等语句(plot train diagram)

该程序是用C 语言编写的图形学中的贝济尔曲线,简单实用易懂(this program is Bezier program about computer picture,wich is degn by c.)

这是国外的同行编写的画图板程序，感觉比陈建春的要好些，说实话研究了半天，发现国内的cad水平低不是因为国内的人笨，主要是国外的cad技术不能很快的传递到国人手中，总是参考陈建华等水平有限，工程水平差的书籍造成整体水平低，书中没有详细的流程图，和软件设计思路，而且代码错误连篇。(This is the foreign counterparts of the drawing board to prepare procedures, CHEN Jian-chun than feeling the need to better tell the truth for a long time study and found that low levels of domestic cad because people are not stupid, mainly abroad cad technology should not quickly delivered to the the hands of the people always refer to Chen Jianhua, such as the limited level, engineering level difference caused by the overall level of books low, the lack of a detailed flow chart of the book, and software design, and code errors pack.)

非常强大的光学仿真软件，可以模拟光线的反射、折射、以及绘制各种像差曲线例如球差、色差。(Very powerful optical simulation software can simulate light reflection, refraction, and the mapping of various aberrations such as spherical aberration curves, color)

用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response curve )

a simple ct & pt model in pscad.

cad 转svg矢量图，很好用的工具，很有用，尽管放心使用(CAD SVG vector map, a very good tool, very useful, despite the ease of use)

通过折射率计算色散，并绘制曲线，适合做色散匹配等用途。(Calculate dispersion by refractive index and plot curves)

检查等高线点线矛盾工具，检查等高线节点与高程点是否矛盾(Check contour line point contradiction tool)

可以批量绘制全潮海流观测的流速流向曲线图,以大潮为例.只需将观测数据写为xlsx格式,即可自动出图.可以支持多个xlsx文件批量绘制.(You can draw all tidal currents observed mass flow rate of the flow graph to tide Case observational data simply written as xlsx format, you can automatically plot can support multiple xlsx file batch rendering.)
