水临界点

实验均发现在跨越水临界点时矿物（或岩石）与水反应的动力学涨落。

Those experiments found the fluctuation of reaction rates of minerals in water in the case of crossing the critical state of water .

超临界水处于临界点以上，其密度、扩散系数、粘度、介电常数、溶解度等物性较亚临界发生了明显变化。

In comparison to the subcritical state , the physical properties of the water medium including density , diffusion coefficient , kinematic viscosity and dielectric constant change more greatly when it works above the thermodynamic critical point .

在超临界压力下，水在拟临界点附近物性发生急剧变化，流动和传热相互耦合为复杂的非线性关系，使超临界水堆系统中流动与传热特性极其复杂。

Under supercritical pressure , thermo-physical properties of water experience abrupt variation around the pseudo-critical point , which couples nonlinearly with heat transfer and flow and makes heat transfer and flow features rather complex .

由于水在伪临界点附近的许多物性参数会有非常明显的变化，这种物性参数的剧烈变化会使水在超临界状态下出现一些与次临界状态下不同的流动特性。

Due to the strong variation of the thermal-physical properties of supercritical water in the vicinity of the pseudo-critical point , the behaviors of water in supercritical condition are significantly different from that in sub-critical condition .

2）水溶液的第二个临界点是气水溶液的超临界点（374.15℃，2.21×107Pa）；

Super critical point of the vapor water solution , the second water critical point ( 374.15 ℃, 2.21 × 10 7Pa );

超临界水冷却反应堆（SCLWR-H）系统是一种高温高压的水冷反应堆，它可以在高于水的热力学临界点（374℃，22.1MPa）的工况下运行。

Super critical light water cooled reactor ( SCWR ) is a high temperature , high pressure water cooled reactor , which can operate above the state of the thermodynamic critical point of water ( 374 ℃, 22.1 MPa ) .
