带电粒子在组合场中的运动,往往涉及重力场、电场、磁场等知识内容,综合性强,因此它是高三复习的焦点内容。组合场是指电场与磁场同时存在,但各位于一定的区域内,并不互相重叠的情况。带电粒子按照时间与空间依次进入不同的场区,享受着电场、重力场、磁场给他们带来的不同风味,有平抛运动、斜抛运动、圆周运动、直线运动,在运动过程中享受不同的规律。这些题目虽然设计非常巧妙,但我们发现这 The movement of charged particles in the combined field often involves the knowledge of gravity field, electric field, magnetic field and so on. Therefore, it is the focus of the third year review. Combinatorial field refers to the electric field and the magnetic field exist at the same time, but each located in a certain area, do not overlap each other. Charged particles enter the different fields in turn according to time and space and enjoy the different flavors brought by electric field, gravitational field and magnetic field. They have flat throwing action, oblique throwing action, circular movement and linear movement, enjoying different during the movement The law. Although the design of these topics is very clever, but we found this
