Day 47 臨界點 Critical point

指由一種狀態變成另一種狀態前,應具備的最基本條件。例如臨界溫度便是氣體能液化的最高溫度。後亦用以形容事態發展的待變狀況。臨界點達到臨界時所具有的值稱之。臨界點的由來由 物理學而來,物理學中因為 能量的不同而會有相的改變(例如：冰→水→ 水蒸氣),相的改變代表界的不同,故當一事物到達 相變前一刻時我們稱它臨界了,而臨界時的值則稱為臨界點 。

Refers to the most basic conditions that must be met before changing from one state to another. For example, the critical temperature is the maximum temperature at which the gas can liquefy. It is also used to describe the changing situation of developments. The value that a critical point has when it reaches criticality is called. The origin of the critical point comes from physics. In physics, there are changes in the phase due to different energy (for example: ice→water→water vapor). The phase change represents the difference in the boundary, so when a thing reaches the phase change, At the moment we call it critical, and the critical value is called the critical point.
