主　　题：initial layer weighted energy functional multiple scaling asymptotic expansions 

摘      要：In this article we study quasi-neutral limit and the initial layer problem of the drift-diffusion *** from others studies,we consider the physical case that the mobilities of the charges are different..The quasi-neutral limit with an initial layer structure is rigorously proved by using the weighted energy method coupled with multi-scaling asymptotic expansions.
