摘要
在“相交”与“相切”、“边界内”与“边界外”、“相对静止”与“相对运动”相互转化的物理过程中,灵活运用相应的物理知识和方法深入分析,挖掘其中的临界条件,建立起正确的物理模型,从而达到开发、挖掘学生的开拓创新的思维能力的目的。
The thesis is mainly about the physical process in the interchange of "intersection" and "intercut", "inside the border" and "outside the border", and "relative static" and "relative movement", through using flexible physical knowledge and methods to analyse and dig out the " Critical Conditions", and build the correct physical model, in order to achieve the target of developing students" creative thinking.
