查询词典 stellar

Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1 stellar radiation may be represented by some black body equivalent and 2 within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear.

本文對着當前的發展，綜述了照相方法在恆星光度学中的地位。接着用兩個簡單的假设，即星体幅射的黑體近似和累積亮度範圍中的直线近似，把恆星光度学中的基本定義(如有效波長、等光波長和色指数等)和主要问题(如空間红化，亮度效应等)表以公式。

We calculate the inclinations of the stellar disks of these galaxies from observational data archives and discuss whether there is a relation between the orientations of the stellar disks and the accretion disks generating masers.

计算得到了这些源的星系盘的倾角，并分析讨论了这些水脉泽源星系盘和脉泽盘的倾角可能存在的相关。统计发现只有大约10%的盘脉泽源的星系盘侧面对着我们的视线。

Based on the results of the contrast of star to sky background in daytime, the detectable stellar magnitude limits are computed and analyzed as functions of observing heights, solar zeniths angle, wavebands and stellar spectral types for 3°×3° field of view.

根据恒星和白天大气背景辐射的对比度，计算和分析了3°×3°视场下，可探测星等极限值随观测高度、太阳天顶角、波段和恒星光谱类型的变化情况。

Mr Cameron—who has an "implementation unit" devoted to working out how his policies will be put into practice, and a stable if not stellar shadow cabinet—claims to be readier for power than any recent incoming prime minister.

大卫·卡梅伦，就像是一个"应用元子"，专心将他的政策付诸于实践；又像是杰出的影子内阁，或者更像是一个饲养千里马的马厩——宣称自己比任何一位首相候选人做出更充分的准备。

In stellar spectra, the H - epsilon line ( transition 7-2) is often mixed in with another absorption line caused by ionized

在恒星光谱中，H -ε线(7跃迁至2)经常会与其他的吸收谱线混合，天文学家都知道电离的

Several explanations have been proposed, including cycles of magnetic activity somewhat similar to our own Sun's sunspot cycle, the action of companion stars orbiting around the dying star, and stellar pulsations.

现在有几个被提出的解释，包括像我们自己的太阳黑子周期的磁场周期活动，围绕衰老的恒星轨道有规律运动的伴星。

The time has finally arrived for the fall albacore blitzes, and this was nothing less than stellar for fly anglers along the Jersey coast as hordes of false albacore invaded our inshore beaches.

这个时刻终于来到了属于鳍闪电的，这是任何低于恒星为苍蝇钓鱼沿线泽西海岸散户虚假鳍入侵我国近岸海滩。

If the stellar spectrum is known, the albedo of the dust can be obtained

如果恒星的光谱已知，就可得出尘埃的反照率。

By complete discrimination system of polynomial algebraic equation and resultant theory, a symmetry class of quartic systems with stellar node is studied.

利用多项式代数方程的判别系统理论和结式理论，讨论了具有星形结点的一类对称四次系统的代数分类，并对系统进行全局分析。

It is likely that the pre-stellar gas has more angular momentum in theprimordial case, and this is borne out by cosmological simulations.

在原初时期，形成恒星的气体很可能具有更多的角动量，这已得到宇宙学的数值模拟的证实。

He became prime minister in 1997 and won international acclaim for his role in the Northern Ireland peace process.

他在1997年成为总理，并且因为在北爱尔兰的和平进程中发挥的作用受到国际社会的赞许。
