摘　　要：Java虚拟机（JVM）作为Java程序与操作系统之间的桥梁，解决了Java程序在异构操作系统上运行的问题．但现有JVM功能模块之间的强耦合性，给JVM结构和指令集的扩展带来了困难．本文基于抽象机模式设计的JVM．通过将JVM的静态特性和动态特性定义为分离组件来分散关注点，以及抽象机模式与JVM固有特性的结合实现的JVM具有松散的耦合度．可扩展的结构和指令集．以及易分配的指令语义．As a bridge between Java programs and operating systems, Java V＇Lrtual Machine （JVM） solved the problem of executing Java programs on different operating systems. But the strong coupling properties among current JVM function modules have brought difficulties to the extension of JVM structure and instruction set. This paper describes JVM, which is based on Abstract Machine pattern. Through the separation of concerns which is implemented by defining the static and dynamic features of JVM as separate components, and the combination of the Abstract Machine pattern and the inherent features of JVM. It implemented a JVM, which is of loose coupling, extensible structure and instruction set, and assignable instruction semantics.
