A person inside will radiate body heat, which moves around the igloo by convection, and is lost through the walls by conduction.

冰屋里面的人会辐射热量，通过对流作用，热量不断地在屋内流动，但这些热量，由于传导作用，会散发出去。

Others, like the fennec fox, have large ears that radiate body heat, helping to cool them down.

其他动物，如耳廓狐，则有大耳朵，可以散发体温，帮助身体降温。
