type supernovae的意思|示意

Type Ia supernovae are so luminous that they outshine their host galaxies for several weeks.

Ia型超新星如此之亮，以至于在几个星期内它的寄主星系的光芒也相形见绌。

By the late 1980s, a suitable standard candle had been indentified: type Ia supernovae.

到上世纪八十年代末，一个合适的标准烛光出现了，它就是Ia型超新星。

The other six galaxies recently hosted Type ia supernovae that are reliable distance indicators for even farther measurements in the universe.

其他6个星系最近都爆发了Ia型超新星——测量遥远宇宙距离时更可靠的量天尺。

One particular sort, though, known as type Ia supernovae, always explode with about the same energy and are therefore equally bright.

不过，有一类被称为Ia型的超新星爆炸时释放的能量始终基本相同，因此量度也相同。

Type Ia supernovae all explode with nearly the same amount of energy and therefore have almost the same intrinsic brightness.

Ia超新星爆发时辐射的能量几乎相等，因而具有几乎相同的本征亮度。

Supernovae of this type have been observed for decades and we have learned that they are very predictable in the way they evolve.

这种超新星已经被观测了好多年，我们也知道了它们是能够按照它们的演变规律可以预测的。
