Abstract (2. Language): 
In this paper , We liave proved that a projectively Rat Sasakian manifold is an Einstein manifold. Also, if an Einstein Sasakian manifold is projectivelly flat then it is locally isometric; with a aunit sphere Sn (1). It has also been proved that if in an Einsten Sasakian manifold th~e relation R(X,Y),P= 0 holds, then it is locally isometric with a unit sphere Sn.
