也谈虚位移原理中广义坐标的选择

On selecting generalized coordinates in virtual displacement principle

讨论了在应用虚位移原理时选择广义坐标应注意的问题 。

Some problems in determining generalized coordinates in the application of virtual displacement principle are discussed, it is pointed out that the correct selection of generalized coordinates is based on the correct understanding of the definition of generalized coordinates.
