  1. As the main-sequence mass of the star increases, the mass of the final remnant left as a white-dwarf star also increases.

    在恆星在主序的質量增加時，作為白矮星留下來的最終殘骸的質量也增加。
  2. The star used to be like the sun, a “ main sequence ” star that burns hydrogen by nuclear fusion, producing helium

    該恆星和太陽一樣是一顆主星序恆星，氫元素通過核裂變生成氦元素。
  3. When a massive proto-star approaches the main sequence, its surface temperature is low and it can not ionize the ambient gas.

    當一個大質量原星接近主星序時，它的表面溫度是低的，因而不能電離周圍的氣體。
  4. When a star is at the main sequence stage, its interior continuously fuses four hydrogen nuclei i. e. protons into one helium nucleus

    在主序星階段，恆星內部不斷把四粒氫原子核即質子融合成一顆氦原子核。
  5. We will discuss what will happen to a main sequence star with a mass over about 8 solar masses

    假若恆星的質量超過八個太陽質量的話，它會怎樣演化呢？
  6. Post - main - sequence star

    主序后星
  7. Particles in the star move around rapidly due to high temperature creating a high gas pressure. together with the radiation pressure generated by the photons, they exert pressure pushing outward to balance gravity s inward pull. then, a star becomes stable and now enters the main sequence phase

    恆星內部所產生的高溫，會令粒子急劇運動，產生向外的氣體壓力，再加上光子的輻射壓力抵消掉向內的引力，令恆星保持穩定，進入主序星階段。
  8. It takes about 0. 1 to 100 million years for the cloud to become a main sequence star

    這個收縮過程需要十萬至一億年，才能演化成一顆主序星。
  9. A heavy star at the upper end of the main sequence has a rather different later history.

    在主序上端的大恆星具有很不相同的晚年史。
  10. The main sequence stage lasts for a long time in the life of a star

    對于大質量的恆星，由於它們的核反應速率很快，大約
  11. After it reaches the main sequence, the star will stay there for millions to billions of years

    一般恆星會在主序星階段逗留一百萬至一百億年。
  12. For example, light emits from the surface of a typical main sequence star falls mainly in the optical window. that is why we can see our sun in daytime and countless stars at nighttime

    例如，大部分主序星表面發射出來的輻射是可見光，因此我們能夠在日間看見太陽，夜間看到漫天星斗。
