critical temperature [计] 临界温度
- The steel is first slowly heated to just above its critical temperature.
首先慢慢把钢加热动略微超过临界温度。 - On exceeding the critical temperature, the structure of the metal begins to change.
一当超过临界温度,金属结构就开始改变。 - Secondly, we can heat the steel above a certain critical temperature, and then allow it to cool at different rates.
其次,可以把钢加热到某一临界温度以上,然后再让它以不同的冷却速度冷却。
critical temperature \crit"ic*al tem"per*a*ture\ (Physics),
A certain temperature, different for different gases, but
always the same for each gas, regarded as the temperature
above which no amount of pressure can produce condensation to
a liquid; the temperature above which a gas cannot be
liquified.
