In this case, the delegation model is a proper graph (with cycles), and so a deadlock can occur as a result of particular class relationships and thread usage.
在本例中，委托模型是一个正确的图(带有循环)，所以死锁的发生可能是使用特定的类关系和线程的结果。
The required alternative input criteria cannot be defined in the basic editing mode, so most backward connections drawn in basic editing mode add a deadlock to the model.
由于在基本编辑模式下无法定义所需的可选输入条件，因此在该模式中绘制的大多数逆向连接都会导致模型死锁。
A deadlock is always a modeling error: some of the desired process behaviors are missing due to non-executable activities in the model.
死锁始终是一个建模错误：因为流程中无法执行某些活动，所需的部分流程行为丢失。
