In this paper, we treat the convex polygon domain as locus of points and give its equation.

在传统解析几何中，平面区域未被作为点的轨迹来看待，因此没有研究平面区域的方程问题。

Kinematic equation of five-bar mechanism with multi-straight-line locus was derived from the theory of mechanics, and animation simulation for the mechanism was programmed by MATLAB language.

基于平面机构运动学理论建立了五杆多直线导向机构运动学模型，提出了由各构件运动方程生成该机构动画的新方法，并在MATLAB平台上开发了该机构动画仿真程序。
