近三年的高考压轴题多以带电粒子在复合场中的运动为主。带电微粒在电场、重力场和磁场三场共存的复合场中的运动问题是近年常考不衰的问题。这类题对学生来说难度较大。解决这类问题重要的就是训练学生熟练、灵活应用数学知识解决物理问题的能力。
Nearly three years of the college entrance examination pressure axis to the majority of charged particles in the field of play-based. The movement problem of the charged particles in the composite field where the electric field, the gravitational field and the magnetic field coexist is a problem that is not deteriorated in recent years. Such questions are more difficult for students. The key to solving such problems is to train students to be skilled and flexible in applying mathematical knowledge to solve physical problems.
