hydrogen main sequence的意思|示意

They calculated that they could be almost twice as common as "main-sequence stars" - such as our own Sun - which are still burning through their hydrogen fuel stock.

他们计算出这种星体的数量是我们“主星序星体”的两倍。我们的太阳就属于“主星序星体”，现在仍然通过燃烧氢燃料发光。

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 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。
