So the control system should be started under large Angleofflow in order to avoiding striking the cylinder.
启动电流随导通角的增大而减小，控制系统应以大导通角启动，可防止撞缸现象。

A five hole probe is used for measuring the tangential Angleofflow, axial velocity, static pressure of flow and swirl number in the flow sections of the conveying system.
应用五孔感头测定沿程截面内气流的切向角、轴向速度、气流静压和旋流数的分布。

When the submersible heads at an Angle into the oncoming flow, the pressure sensors detect the formation of eddies and start the small cylinders spinning.
