In this thesis, soft starter equipment realized by thyristors power transform circuit is studied. To improve equipment performance, we apply variable reactance technique to AC motor soft starter study. The high voltage AC working winding of reactance is in series with motor winding, while low voltage control winding and thyristors groupware with intelligent controller constitute close loop circuit. We adopt thyristor phase control voltage-regulator mode to control low voltage winding, then control the reactance of high voltage winding, and then arrive at the goal-control the current and voltage of motor AC to realize motor soft starting.

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
