选择研究对象是解决物理问题的首要环节.在很多物理问题中,研究对象的选择方案是多样的,研究对象的选取方法不同会影响求解的繁简程度.合理选择研究对象会使问题简化,反之,会使问题复杂化,甚至使问题无法解决.隔离法与整体法都是物理解题的基本方法.隔离法就是将研究对象从其周围的环境中隔离出来单独进行研究,这个研究对象可以是一个物体,也可以是物体的一
Selecting the research object is the first link to solve the physical problem. In many physical problems, the research object selection scheme is diverse. Different research object selection methods will affect the complexity of the solution. Reasonable choice of research object will simplify the problem, and vice versa. It will complicate the problem and even make it impossible to solve the problem. The isolation method and the holistic method are the basic methods of object understanding. The isolation method is to isolate the research object from its surrounding environment and carry out independent research. This research object can be An object can also be an object
