用于求解各阶贝塞尔函数和汉克尔函数零点，希望对大家有帮助。(besselj and hankel functions)

二维绘图，包括直线，矩形，圆，多边形等绘制(Two-dimensional graphics, including lines, rectangles, circles, polygons drawn)

针对ANSYS开发的APDL，该命令流用于生成中国60kg钢轨，从而避免了繁琐的多曲线建模，十分方便。另外，基于该命令流，用户可以推演出更复杂的型面优化建模。(Developed for ANSYS APDL, the order flow is used to generate Chinese 60kg rails, thus avoiding the cumbersome multi-curve modeling, very convenient. In addition, based on the order flow, the user can deduce a more complex profile optimization modeling.)

简单的图形学SRGP教学包运用实现。 A．实现一个下拉菜单软件包，其高层设计见2.2.6节、2.3.1节、2.3.3节中的代码段。软件包通过从输入文件读入字符串来初始化菜单条和菜单体。程序可以通过关闭菜单条使标题消失，也可以激活一个菜单（以各菜单标题在菜单条上的水平位置作为参数）来使菜单出现。 (Simple graphics SRGP realize the use of teaching packages. A. The realization of a drop-down menu package, and its high-level design, see section 2.2.6, section 2.3.1, section 2.3.3 of the code segment. Package from the input file is read into the string to initialize the menu and menu body. Procedures can be closed so that the title menu disappear, but also can activate a menu (in the menu heading in the menu bar on the horizontal position as a parameter) to make the menu appear.)

PSCAD仿真,可以设置各种故障,故障类型可以自由设置,并且得到故障仿真图形,本程序中附有单相故障(PSCAD simulation, you can set a variety of failures, fault types can be set free, and get fault simulation graphics, the program with a single-phase failur)
