Abstract：
When constraints of a system form a function group, the path integral quantum amplitude can exactly be beduced without adding the restrictions {χ _i,χ _j}=0 which are imposed on the gauge conditions or the "weak" concept. It can be shown that the contraints produced by symmetry just form a function group. Most of the interesting systems in physics are such symmetrical systems.
