What is called unidirectionalcircuit is a circuit whose branches airflow directions are uniform.
所谓单向回路就是风路风流方向相同的回路。

If the two endpoints of a route are the same node, the route is a circuit; if the two endpoints of a path are the same node, the path is a unidirectionalcircuit.
当路径的两个端点重合时就是回路,通路的两个端点重合时就是单向回路。

An equivalent circuit model of these 3-phase unidirectional transducers is discussed as well as their adjustment and fabrication.
