To correctly capture cyclic processes, add backward connections to the process model that connect to an upstream activity.
要正确捕获循环流程，请在流程模型中添加连接上游活动的逆向连接。
2
Within the Cyclic Flow activity, connectors can go backwards to a previous activity.
在循环流活动中，连接器可以向后返回到某个以前的活动。
3
When an activity is skipped in an end state, the request targets the next iteration of this activity, for example, if it is located inside a while loop or inside a cyclic flow.
当跳过某个处于结束状态的活动时，请求将指向此活动的下一个迭代，例如，如果该活动位于 while 循环中或者在循环流中。
