SAT2物理有关固体热胀冷缩的问题
书上说:“brass expands more than iron.when heated,the bimetallic(这个是有iron和brass组成的一个双金属条)strip bends,with the brass forming the outside of the curve.in cooling,the reverse happens;"没有明白这个reverse的过程究竟是怎样.是指brass冷缩的变化也比iron大还是其他意思?

你说的是对的.
指冷却时,brass冷缩的变化也比iron大,这样iron就是the outside of the curve.
