说明：  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.)
