带电粒子(不计重力)垂直磁感线进入磁场可以发生偏转,我们简称“磁偏转”;如果带电粒子垂直电场线进入电场也可以发生偏转,简称“电偏转”,有时候这两类偏转轨迹极其相似,但在原理上却截然不同.在解答这两类习题时,所用的规律、方法也不同.本文将就这两类偏转的区别作一归类例析,以飨读者. Charged particles (excluding gravity) perpendicular magnetic induction line can enter the magnetic field can be deflected, we referred to as “magnetic deflection”; if the charged particle vertical electric field lines into the electric field can also be deflected, referred to as “electric deflection”, and sometimes these two types of deflection trajectory is extremely Similar, but in principle it is completely different. In answering these two types of exercises, the laws and methods used are also different. This article will be a classification of the difference between the two types of deflection analysis, in order to readers.
