Abstract: Using p-open sets,the authors give  the definition of Pi(i=0,1,2,3,4) spaces and discuss their characters.The author also define p-cover and discuss the relations between Pi(i=0,1,2,3,4) spaces and Ti(i=0,1,2,3,4) spaces.A new compact space——P-compact space is defined,and the characters of P-compact space and the relations between P-compact space and Pi-space are discussed.Thus,several conclusions are drawn.

Key words: p-cover, P-compact space, Pi(i=0,1,2,3,4) space
