P11 Cancelling Partial Joint 取消部分合并

Pattern 11 Cancelling Partial Join 取消部分合并 The convergence of two or more branches (say m) into a single subsequent branch following one or more corresponding divergences earlier in the process model. The thread of control is passed to the subsequent branch when n of the incoming branches have been enabled where n is less than m. Triggering the join also cancels the execution of all of the other incoming branches and resets the construct. 合并多条路径，进行部分同步，只执行一次后续活动，同时取消所有其他路径的执行。 例子：在三个分支中的任意两个到达之后启动后面的活动。
