摘要
从场论中正则形式的作用量出发,导出了场论中奇异系统的Poincaré-Cartan积分不变量;讨论了该不变量与约束系统的正则方程、正则变换间的联系;纠正了一些文献中出现的错误。
Baesd on the canonical action for field theory,the Poincare-Cartan integral invariant for singular system was deduced.This invariant in connection with canonical equations,and canonical transformation of constrained Hamiltonian system was descussed.Some confusions in the literature was corrected.
