When the Sun first became a main sequence star, it radiated only 70% of the current luminosity.
当太阳首次成为主序星，它的辐射只有当前光度的70％。
A star during most of its life is a main-sequence star, which consists of a core, radiative and convective zones, a photosphere, a chromosphere and a corona.
一颗恒星其生命的绝大部分处于主序星阶段，在这一阶段它包含一个核心、辐射区和对流区、光球层、色球层和日冕。
The greater the mass of such a star, the more quickly it will use its hydrogen fuel and the shorter it stays on the main sequence.
恒星的质量越大，它消耗氢燃料的速度也就越快，它在主序中停留的时间也就越短。
The sun is thought to be about 5 billion years old and halfway through its lifetime as a "main sequence" star.
太阳现在的寿命大约是50亿年，作为一颗“主序”恒星，也只是过了生命的一半。
The star used to be like the sun, a "main sequence" star that burns hydrogen by nuclear fusion, producing helium.
这颗恒星曾和太阳一样，是颗“主序星”(“main sequence”)。它通过核聚变燃烧氢，从而产生氦。
The second Death Star's firing sequence differed as the central "eye" punched through the tributary beams, something the Death Star from Star Wars did not do.
第二颗死星的开火镜头有所不同，其中央“眼”射穿分支激光束，这是《星球大战》的死星所不具备的。
A heavy star at the upper end of the main sequence has a rather different later history.
在主序上端的大恒星具有很不相同的晚年史。
The zero-sequence differential protection ought to be added at the star winding of extra-high voltage transformer.
接线绕组的超高压变压器应增设零序差动保护。
When a massive proto-star approaches the main sequence, its surface temperature is low and it can not ionize the ambient gas.
当一个大质量原星接近主星序时，它的表面温度是低的，因而不能电离周围的气体。
Multiple Sequence alignment (MSA) is a typical NP-Complete problem. Star alignment is an effective algorithm for MSA.
多序列比对(msa)是一个典型的NP完全问题，星比对是一种有效的多序列比对算法。
