UMERICAL METHODS FOR A MODEL OF COMPRESSIBLE MISCIBLE DISPLACEMENT IN POROUS MEDIA
一类可压缩流体驱动问题的有限元方法

For a model of compressible miscible displ cement,two semi-discretization procedures areestablishel using finite element or mixed element methods.First,local existence of the solution ofthe procedures is proved.Then,the optimal error stimate is derived while the solution is extendedalternately to the total time region 0,T].
