摘　　要：得到了局部对称拟常曲率黎曼流形中的拼挤常数,使得常曲率空间形式的相应拼挤常数是它的特例.The pinching constant of locally symmetric quasi-constant curvature Riemannian manifold is obtained. It indicates that the pinching constant of constant curvature space form is special case of locally symmetric quasi-constant curvature Riemannian manifold.
