带电粒子在复合场中的运动是近年高考的重点和热点.命题常以构思新颖、情景复杂、综合性强为特点,常把场的性质、运动学规律、牛顿运动定律、功能关系及交变电流等有机的结合起来以计算题命题考查,难度中等偏上,对考生的空间想象能力、综合分析能力和运用数学方法解决问题的能力要求较高.一、带电粒子在复合场中的运动情况 The movement of charged particles in the compound field is the focus and hot spot of the college entrance examination in recent years.The proposition is often characterized by novel ideas, complex situations and strong comprehensiveness, often the field nature, kinematics law, Newton’s law of motion, functional relationship and alternation Current and other organic combination to calculate the title of the test test, the difficulty of the upper middle of the candidate’s spatial imagination, comprehensive analysis capabilities and the ability to use mathematical methods to solve the problem of higher requirements.
