摘要：

In this paper, Noether symmetries of some spacetime metrics are studied. Considering invariance of the action integral under one parameter Lie group of transformations, it is shown that a large class of Noether symmetries is found. In particular, it is shown that the isometries form a sub-Lie algebra of Noether symmetries.
