commutation condition

基本解釋

On the condition that there is no material commutation with outside, healing of internal crack and hurt of material depends on the move of internal material and the change of structure.
在與外界無物質(zhì)交換的條件下，材料內(nèi)部裂紋與損傷的愈合靠內(nèi)部物質(zhì)遷移及結(jié)構(gòu)變化完成。
In this paper, the condition of commutation is analyzed, the lead angle is studied when the rotary direction of motor is changed, and the commutation logic with different lead angle is proposed.
本文較全面地分析了換向條件，研究了正反轉(zhuǎn)時位置反饋信號與旋轉(zhuǎn)電勢的相位關系，并給出了不同超前角時的換向邏輯。
This paper compares the commutation failure different results caused by AC system fault and missing pulse in the condition of prediction extinguish angle in ABB HVDC control and protection system.
比較了在ABB直流控制保護系統(tǒng)中采用預測型關斷角的前提下，由于交流系統(tǒng)故障和丟失脈沖所引起換相失敗的不同后果。
