synchronized model

In particular, the memory model defines semantics for volatile, synchronized, and final that make guarantees of visibility of memory operations across threads.

特别是，内存模型定义了保证内存操作跨线程的可见性的volatile、synchronized和final的语义。

Based on four different reference frames, namely absolute angle synchronized reference frame, relative angle synchronized reference frame, reference frame in which some machine is taken as reference machine, and inertia center reference frame, methods of forming linear space model of multi-machine systems are introduced.
