Direct Torque Control is a novel torque controlling technique which was proposed in 1980's. Although this technique has received a successful application in high-power ac drives recently, there are also a great deal of problems in the theories and practics which deserve to research. Centring around how to find and solve these prombles, theorical analyses, computer simulation and experimental studies are carried out in this dessertation.

直接转矩控制是八十年代提出的一种新型感应电机转矩控制技术，目前该项技术在国外电力牵引中的大功率交流传动上已获得成功的应用，然而作为一项新技术，它在理论上和实践中仍存在许多值得研究和探讨的问题，本文的研究正是围绕着这些现存问题而展开的。

In teaching process's teachers and students relations,"teach for the leadership, studies is the main body" expression, regardless of being theoretically or as if is accepted in the practice utilization by the general pedagogues, but the teaching actual massive facts indicated that "teaches for the leadership" often to become "teaches for the control".

教学过程中的师生关系，&教为主导，学为主体&的表达，无论是在理论上还是在实践运用上似乎都被广大教育者所接受，但教学实际的大量事实表明&教为主导&往往变为&教为主宰&。

Shihu gold deposit in Hebei Province, belonging to pyrite sulfide type,is characterized by multistage mineralization,but the main stage of mineralization is almost coincident with the mass separation of sulfideThe sulfur in sulfide and mineralizing hydrothermal solution is derived from anatectic granitic magma.

河北省石湖金矿属于黄铁矿硫化物型金矿，具有多期次成矿的特点。但金的主要成矿阶段与硫化物的大量析出阶段在时间上基本一致。硫化物及成矿热液中的硫来自深熔花岗质岩浆。从微观结构和晶体学理论上对金的赋存机理进行了讨论。

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。
