从奇异拉氏量系统相空间路径积分的量子化形式出发,导出了系统在增广相空间整体变换下的广义正则Ward恒等式和量子水平的守恒荷,一般这些守恒荷有别于经典Noether荷.给出了在杨-Mils场论中的应用,找到了新守恒荷Starting from the quantization formalism of the phase-space path integral for a system with a singular Lagrangian, the generalized canonical Ward identities and conserved charges at quantum level are deduced under the global transformation in extended phase space. In general, the quantal conserved charges are different from classical ones. We give a preliminary application to Yang-Mills theory,the new quantal conserved charges are found.
