临界温度：钢材加热使得内部结构产生奥氏体时的温度。通常大部分钢材的临界温度在华氏1350度到1500度之间。
CRITICAL Temperature: Temperature at which, upon heating, a steel transforms into the structure called Austenite. For most steels this occurs between 1350 degrees F. and 1500 degrees f.
淬火。这个工艺是把材料加热到临界温度范围之上，然后迅速冷却到临界温度范围以下，使钢材明显变硬。
Hardening. This is the process of heating to a temperature above the critical range, and cooling rapidly enough through the critical range to appreciably harden the steel.
临界点或者临界温度是指钢达到其最合适性能时的点。
The critical point, or critical temperature, is the point at which the steel has the most desirable characteristics.

临界压力与临界温度一起用来确定流体存在的状态(液体或气体)，并用来计算压缩因子。
Critical pressure is used along with critical temperature to determine the state in which a fluid exists (liquid or gas) and to calculate compressibility factors.

使气体临界温度时液化所需要的最小压力就是该气体的临界压力。
The minimum pressure required to liquefy a gas at its critical temperature is its critical pressure.
临界温度附近的吸附机理低压下为单分子层，高压下转变为多分子层； 远离临界温度时吸附机理仅为单分子层。
