论文摘要
给出了Sundman Infitice Air-Itimal-timer-AparameTryation的几何方法，并使用其某些应用来说明一般理论。特殊的重点是机械类型拉格朗日描述的地球运动和系统。 Jacobi指标似乎是Sundman转型的特殊情况。
A geometric approach to Sundman infinitesimal time-reparametrisation is given and some of its applications are used to illustrate the general theory. Special emphasis is put on geodesic motions and systems described by mechanical type Lagrangians. The Jacobi metric appears as a particular case of a Sundman transformation.
