从自己的经验中,每一个人都知道:在高温的情况下,物质具有比“正常”——地面上大多数的情况不同的另一种性质.我们只要回想一下,物质的熔化和蒸发、发射光线、开始化学反应(例如燃烧).物质的性质也随压力的改变而改变,实质上物质的熔点和沸点依赖于压力.本文论述在继续增加温度和压力时发生的新性能,以及如何解释物质在这些条件下取得的新性质. 开始我们应当明了“温度”概念所表示的意义.
From their own experience, everyone knows: In the case of high temperatures, the substance has a different nature than the “normal” - most of the conditions on the ground. We just have to think about the melting of the material and Evaporation, emission of light, initiation of a chemical reaction (e.g., combustion). The properties of the substance also change with changes in pressure. Essentially, the melting point and boiling point of the substance depend on the pressure. This article discusses the new properties that occur when the temperature and pressure continue to increase, and How to interpret the new nature of the material under these conditions. At the beginning we should understand the meaning of the concept of “temperature”.
