It points outthat there is a problem about AND-JOIN. To solve the problem, the synchronized semantic of AND-JOIN in extend-ed Xinpai-driven model is defined formally. It puts forward the concepts of synchronizedarea and asynchronizedarea. It gives the solution of true-and-false token rules in synchronized area and true token rules in asychronized area,and some other issues arisen from the solution are studied systematically and completely. The constrain issues of con-trol structures in synchronized area and asynchronized area are discussed, and its solution is put forward.
