直流
The converter units generate harmonics which flow in the AC and DC lines. 換流器單元產(chǎn)生的諧波會(huì)流過(guò)交流和直流線路。
Numerical experiments were performed to investigate the instability of flow and heat transfer in a heated rotating cavity with cool air axial throughflow. 利用數(shù)值模擬的方法對(duì)冷氣軸向通流旋轉(zhuǎn)盤腔的流動(dòng)過(guò)程進(jìn)行了研究。
