该程序是用java3d来做的简易传送带模型-The program is easy to do with the belt model java3d

用Ｐｅｔｅｒｓｏｎ算法实现两个传送带互斥，保证工场的分拣器正常工作的小算法。可以看做一个并发系统的基础理解-Peterson algorithm with two conveyor belts mutually exclusive, guaranteed workshops sorting algorithm to work properly small. Can be seen as a basis for understanding concurrent systems
