查询词典 reduces

This paper presents an efficient approach of designing a special dome and its aberration corrector, using the method of Wassermann-Wolf differential equations to generate the optimum contour of the corrector through a macro in CODE V. This corrector reduces spherical aberration and coma which are introduced by the dome and improves the imaging quality of the system.

The research results have shown that the configuration of the magnetic bearing reduces overall system size, and has high efficiency. The axial and radial suspension forces have great linearity. The symmetrical characteristic strenuously, and movement of every degree of freedom around balanceable position has no coupling and the control flux of every degree of freedom is independent. It is beneficial to simplify and design the controller and the circuit power amplifier. The magnetic bearings operate stably with decentralized PID controllers.

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。
