铁路定测中的中桩坐标计算程序，此程序只是计算曲线部分，其方法主要依赖于任一点极坐标法-Railway will be measured in the coordinates in the pile program, this program is only part of the calculation curve, mainly relies on its way to any point in the polar coordinate method

本课程设计以尖顶从动件偏心盘状凸轮机构为例，基于Visual Basic软件编写凸轮轮廓计算机辅助设计程序，实现了既能可视地展示机构的运动，又能给出凸轮轮廓上各点所对应的极角和极径，实现计算机辅助设计。-This course is designed to spire discoid eccentric cam follower, for example, based on the Visual Basic software development, computer-aided design
