摘要：

Let R be a commutative Noetherian ring,I and J be two ideals of R,and M be an R-module.We study the cofiniteness and finiteness of the local cohomology module H;（M）and give some conditions for the finiteness of Hom;(R/I,H;（M）)and Ext;(R/I,H;（M）).Also,we get some results on the attached primes of H;（M）.
