摘　　要：对常见的点合成运动题型分析发现:这类题目可以形象地分为五种类型,即相接型、相切型、相交型、相傍型和相望型。阐述这五种类型的各自特点,给出相应的动点—动系的选取。The frequently used exercises and examples relevant to composite movement were surveyed systematically. It is found that they can be categorized exclusively into five classes, viz., the touching, tangential, intersecting, juxtaposing and non-touching classes. The properties of these five classes are investigated, and the optimal selection of moving coordinate systems and moving points is presented.
