1.带电粒子电性不确定受洛伦兹力作用的带电粒子,可能带正电,也可能带负电.具有相同初速度的正、负粒子进入磁场中,它们的运动轨迹不同,故导致多解.
1. Charged particles are electrically indeterminate. Charged particles acted by Lorentz force may be positively charged or negatively charged. Positive and negative particles with the same initial velocity enter the magnetic field. Their trajectories are different. solution.
