柔和燃烧的火焰面分散，燃烧反应在空间较大范围内发生，火焰亮度低，OH信号强度和脉动都非常弱。
The flame of mild combustion is distributed in a large space, flame luminosity as well as OH intensity is very low.
相反，根据量子力学的怪异说法，黑洞就像行将熄灭的火焰里那飘摇的灰烬，其光亮度应该是微乎其微的。
Instead, because of the quirks of quantum mechanics, they should glow ever so faintly, like smouldering embers in a dying fire. The implications were huge.
深色可以给火焰增加亮度，而且要确保你的注意力在火焰本身上，保持背景的简单是很重要的。
A dark color adds intensity to the fire and keeping the background simple to begin with is important to ensure that you concentrate on the fire itself.
