The bigger the object’s area, the faster it will radiate heat.

物体的面积越大， 它散发热量的速度就越快。

The bigger the object's area, the faster it will radiate heat.

身体面积越大，光线越多 加热更快。

And it says that heat emitted over time is equal to the emissivity constant x a special number known as the Stefan-Boltzmann constant x the object’s area x temperature raised to the fourth power.

它说随着时间的推移散发的热量等于发射率常数 x 一个称为 Stefan-Boltzmann 常数的特殊数字 x 物体的面积 x 温度的四次方。
