基本的原理我们都很清楚，并可以在一分钟内给一个不是科学家的好奇者解释完毕（就像这样：温室气体可以让阳光直接穿透到地球表面，地表受热就会升温，于是就会散发红外辐射，辐射能量被大气吸收，大气就被加热了。
We understand the basic physics just fine, and can explain it in a minute to a curious non-scientist.
冬天太阳高度低，穿透有很高太阳能吸热系数的玻璃加热地板，地板本身也充当热质。
In the winter, the low sun penetrates glass with a very high solar heat gain coefficient, and heats the floor, which in and of itself ACTS as a thermal mass.
