摘　　要：当力学系统加上约束时,由直角坐标过渡到广义坐标是特别方便的,而且也是十分必要的.引进广义坐标是分析力学的一大特色,而Lagrange方程就建立在广义坐标上的.这个札记提供广义坐标形成的一些史料,并提出一些看法.When the mechanical system is coupled with the constraints, it is very convenient for the transition from the rectangular coordinates to the generalized coordinates, and it is also very necessary. The introduction of generalized coordinates is one of the major features of analytical mechanics, and the Lagrange equation is based on the generalized coordinates. In this paper, some relevant history data of the formation of generalized coordi- nates are provided, and some propositions are given.
