For confirming the method's efficiency, the turn-off transient mathematical model based on the chopper circuit is developed according to the proposed mathematic model of the turn-off transient current through IGCT, in which the RC-snubbers of IGCT, the stray inductance of chopper circuit and DC-link choke are taken into accounts.

该文建立基于斩波电路的IGCT关断暂态特性的数学模型。该模型充分考虑IGCT阻容吸收回路、线路杂散电感及限流电抗器对IGCT关断暂态过电压的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
