摘要：
A study of Kantowski-Sachs and Bianchi type III spacetimes according to their proper curvature collineations is given by using the rank of the 6 x 6 Riemann matrix and direct integration techniques. It is shown that when the above spacetimes admit proper curvature collineations, they form an infinite dimensional vector space.
