Above the critical temperature and under high pressure the vapor may become as dens and as incompressible as the liquid at lower temperature.

在临界温度以上和高压下，蒸汽密度可能变得象在低温下液体那样稠密且不可压缩。

FERRITE: a room temperature structure of steel formed when slow cooled from above the critical temperature. Low in carbon and relatively soft.

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.

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。

To maintain the critical temperature, Dr Zheludev uses a small electronic heat pump known as a Peltier cell.

At this temperature, the mirror was able to flip between high and low reflectivity over a million times a second suggesting that, if it can be kept reliably at this critical temperature, gallium will make a fast (and also small and cheap) optical switch.

Now, a study has uncovered a third part of the brain that, at least in mice, shows positive signs of neurogenesis: the hypothalamus, associated with body temperature, metabolism, sleep, hunger, thirst and a few other critical functions.
