查询词典 operator

This technique,called the rotation operator approach,disentangles the propagator into a rotation operator and,consequently,shifts the cumbersome time-ordering problem into solving the characteristic equations equivalent to the Euler geometricequations long known to describe the motion of a rigid body.

它把相应的传播子分解为量子力学中的空间转动变换算符，把复杂的时序问题转变为求解对应的特征方程，而这些特征方程恰好与描述刚体运动的Euler几何方程完全等价。

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。
