With the extension of the application,it is necessary for certain software to be transplanted from one operating system to another.An abstract layer of operating system is constructed by using the object oriented method.When an application program is transplanted,it needs not to be modified and only several parameters in the interface of the abstract layer need amending.It is convenient for the application programs to be transplanted.The abstract layer can supply a unified operating system interface to the applications,and define the exact operating system by using the macro definition mode inside the interface.Practical results indicate that the combination of two methods has good effect.
