中学物理教学中的隔离体解题法(简称隔离法),可以运用于求解动力学问题,也常用来处理静力学问题,应用范围很广,差不多所有研究物体客观性质的力学都离不了它。在中学阶段,应当对学生进行必要的训练,使他们掌握隔离法的技巧。一、隔离法和它的理论基础所谓隔离法,就是根据问题的要求,把需要研究的那部分物体想象地从与之联系着的周围物体中分离出来,单独分析它的受力情况和运动情况的方法。被单独隔离出来进行研究的那个物体(或几个物体组成的物体系),一般就叫做隔离体。
In the physics teaching of middle school, the problem of isolated body solution (referred to as isolation method) can be used to solve kinetic problems and is also often used to deal with the problem of static mechanics. It has a wide range of applications. Almost all the mechanics of the objective properties of the studied objects are inseparable from it. In the secondary stage, students should be given the necessary training to equip them with the techniques of isolation law. Isolation method and its theoretical basis The so-called isolation method is based on the requirements of the problem, the need to study that part of the object imaginary from the surrounding objects associated with it, separate analysis of its force situation and movement Methods. The object (or a system of objects) that is isolated and researched separately is generally called a barrier.
