查询词典 luminosity

The luminosity of the most of extraglactic H2O megamaser sources is between tens and hundreds L ⊙, but one of the extragalactic H2O megamaser source TXFS 2226-184 is 6100 L ⊙. It belongs to the class of radio galaxy and is not general. It is mainly caused by its wide spectral profile.

多数河外H2O超脉泽源的光度在几十至几百个 L ⊙之内，但TXFS2226－184源的河外H2O超脉泽源的光度达6100 L ⊙，它属于射电星系类型，是主要由于其谱线轮廓较宽所造成的一种例外情况。

At a distance of 750 light years, we calculate Sadalmelik to have a luminosity 3000 times that of the Sun, rendering it about 60 times the solar diameter, large, but nowhere near as large as the truly great supergiants that would fill the orbit of Jupiter.

将其置于750光年的距离处，可算出它的亮度为太阳的3000倍，大小是太阳系的60倍，这个尺度使仅能够填充木星轨道的真正巨星望尘莫及。

The observed gamma-ray luminosity implies an upper limit of 60 millisecond pulsars present in 47 Tucanae.

根据测量的伽玛射线光度我们得到47 Tucanae中毫秒脉冲星的数量上限为60个。

The unsurpassable luminosity of the dials in conditions of extremely poor light is just one example that nevertheless gives an idea of the company's tireless commitment to research.

这些产品凭借在当时具有突破性意义的高科技打造出一系列非凡的特色，很快在市场上取得独树一帜的地位。

Single-Chip Microcomputer software actualizes its judging by luminosity to stop the switches working even though there is voice in the daytime.

单片机软件实施对光度的判断，使开关在白天时即使有声音也不工作。

Emptiness is the true nature of the mind, but the mind also possesses a quality of all-pervasive luminosity at the same time.

心的本质乃为空性，同时心亦具有一种无碍的光明。

Cepheids that have identical cycle times of brightening darkening and brightening again also have identical or nearly identical luminosity.

造父有相同周期的时候，翩翩喷砂和翩翩再次也有着一致或接近一致的亮度。

By observing Cepheids with very similar properties at near-infrared wavelengths in all seven galaxies, and using the same telescope and instrument, the team was able to more precisely calibrate the luminosity of supernovae.

通过很相似的方法，在全部7个星系中用相同的望远镜和仪器，在近红外波段观测造父变星和超新星，团队能够更加精确地校准Ia超新星的光度。

The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个&阶梯&：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。

The "luminosity" of a collider is a quantity proportional to the number of collisions per second.

碰撞的亮度是与每秒钟碰撞次数成正比的。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
