The flow coefficients of the orifice-plate flowmeters are experimentally studied with or without a rectifier at the lower reach of a space elbow in the measuring pipe of flow.
通过实验研究，观察分析了流量测量管路中空间弯头下游有(或无)整流器时对孔板流量计流量系数的影响。
The normal work of the diode is guaranteed by the heat dissipation of a conducting pole plate, which can improve the reliability of the auto rectifier, and prolong the service life of the rectifier.
通过导电极板散热来保证二极管的正常工作，可提高汽车整流器的可靠性，延长整个整流器的使用寿命。
