【Abstract】 In this paper,we discussed some properties of Lie groupoids as a bundle,and obtained the conclusion that its Inner subgroupoids is a principal bundle.Studied the actions of Lie groupoids on its Inner subgroupoids,proved the result that its Maurer-Cartan forms acting on left invariant vector field is a constant.A proposition about the morphisms of Lie algebroids is generalized.更多还原
