请以光通量为亮度标准，发光强度仅供参考。

Please take Luminous Flux as standard parameter, Luminous Intensity is only for reference.

因此建立一个高精度的光谱辐照度和光谱辐亮度标准是非常必要的。

The Gauss model of point target image irradiance and the calculation model of the infrared radiation power are established.

这两种图景之间的差异可能会与超新星被当成“标准烛光”(也就是亮度已知的天体)来测量遥远宇宙距离的方式有关。

The difference between these two scenarios may have implications for how these supernovae can be used as "standard candles" — objects of a known brightness — to track vast cosmic distances.
