摘要
在力学上，虽然对体系的拉氏函救Ｌ的选择有一定程度的任意性，但在由Ｌ得出体系的三维哈密顿函数Ｈ时，选择Ｌ的任意性受到了限制。要根据实际情况才能选定Ｌ。
This paper points out although the choice of Lagrangian for the motion of charged particles in the electromagnetic field has some arbitrariness, yet the arbitiarriness is limited, if we wand to obtain a correct three dimensional Hamiltonian, for we must consider the physical situation.
