A sudden slowing in the rate of temperature increase in a metal being heated, caused by endothermic structural changes and resulting in a darkening of the metal.

吸热（变黑）正在加热中的金属，其温度的升高速度骤然减慢，由吸收了热能的结构变化引起，并导致金属的颜色变黑。

Of course, if Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature and pressure will drop until Hell freezes over.

当然，如果地狱膨胀率高于灵魂的入地狱率，那么温度与压力就会降低直到冰封地狱。

With increase of dispersant concentration or decrease of storage temperature, sedimentation rate decreased and final sedimentation ratio increased accordingly.

随着分散剂浓度的增加或储存温度的降低，沉降速度降低，最终沉降比增加。

We know the exact rate at which seawater expands with temperature, and the expected increase in sea level calculated from the observed increase in temperature matches the observed rate of increase of sea level.

FORBES: What If Mike Bloomberg Is Right And A Climate Change Nightmare Is Here?

Since what matters is not just the absolute temperature level but the rate of change as well, it makes sense to try to slow down the increase.
