Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds.

在活动星系核中，Blazar天体是具有极端性质的一类，它以大幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。

The new apochromats were rare instruments, however, as totally apochromatic reflectors began to dominate astrophotography.

然而，当这种新型复消色差镜还是很稀罕的时候，真正的全消色差折射镜正将主宰天体摄影领域。

In the title of the window, the speed and direction of the apparent motion for the object is displayed.

在该窗口的标题栏上显示了该移动天体视运动的速度及方位角。

Its areas of current emphasis are: Computer-Aided Drug Design, Macromolecular Modeling, Pharmacology, Neuroscience, Astrochemistry and Astrobiology.

目前，它的科研重点是计算机辅助的药物设计，大分子建模，药理学，神经科学，天体化学和太空生物学。

In the regions of astrodome physics, solid physics, photochemistry and medicine, measurement and calibration of spectral irradiance of ultraviolet and vacuum ultra-violet have become more and more important research means and instrument.

紫外和真空紫外光谱辐照度的测量和定标，在天体物理、固体物理、光化学及医药学等领域中已成为越来越重要的研究手段和工具。

A set of new theory and method of astrometry are being modified, we should catch up with development of this field.

新的一套天体测量理论和方法正在变更之中，我们应及时跟上这个领域的发展步伐。

Astrometry is a field where bad measures are generally of little or no use.

低质量的天体测量数据是很少有用或无用的。

Also, ensure that you report the magnitudes with the astrometry: do not say "Photometry to follow"!

当然，请确保你使用的是天体测量方法，请不要说"以后再用正规的测量方法"！

The Earth's rotation and revolution Movement was originally astrometry and ground studies of common research topics, but the methods and goals of different.

地球的自转运动和公转运动本来就是天体测量学和地学共同的研究课题，但方法和目的有所不同。

In this sense the astrometry and radial velocity planet-hunting methods complement each other, each excelling in the other method's blind spot.

从这一意义上说天体测量和视向速度行星搜索法是互为补充的，各自在彼此方法的盲区表现出色。

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.

交际能力和语法的关系应该是目标与途径的关系。
