三相点

Some practical problems arising from the adoption of the absolute scale ol temperature as standard in place of the Celsius scale are discussed.

本文对在给定水的三相点的绝对温度以一定的数值(例如T_3=273.1700)，同时以绝对温标代替摄氏温标以后所引起的一些实际问题作了讨论。

Concepts such as "absolute zero" and "triple point of water" are defined.

如"绝对零度"和"水的三相点"概念的定义。

Note that all of these isotherms have a three-phase point, repre sented by the horizontal, broken line.

注意，所有的等温线都具有三相点，且均用水平的虚线段表示。

Temperature Zone 3: From the balanced triple-point of hydrogen(13.803K) to the freezing point of silver (961.78℃). T90 is defined by platinum resistance thermometer.

第三温区为平蘅氢三相点（13.8033K ）到银的凝固点（961.78℃）之间， T90是由铂电阻温度计来定义，它使用一组规定的定义内插法来分度。

For spin-3/2 Isingmodel with transverse crystal field,the tricritical phenomena havebeen observed for the square and simple cubic lattice,but there isno tricritical point for the honeycomb lattice.

横向晶场中自旋为3/2的Ising模型中，对于蜂窝点阵晶格来说，系统相变没有三相点，而正方点阵、简立方点阵晶格却有三相点的存在。

Above the critical point,the second-order phase-transition line between the superfluid and the normal phase is determined.

在三相点温度以上，超流和正常相之间有二级相变。

The curves represent the temperatures and pressures where two phases coexist in equilibrium (at the triple point, the three phases coexist).

图中的曲线代表了两相共存的温度和压力，在三相点三相共存。

In this work, taking into account the molecular fraction and the presence of the 4-atom, we calculated the Gibbs free energy and studied, the influence of the percent of 4-atom on the parameters of the triple point and the critical point.

本文进一步考虑4-原子的存在，计算了有空格点存在时系统的吉布斯自由能，研究了4-原子所占百分数对三相点t_t，P_t值以及临界点t_c，p_c值的影响，获得了具有三相点和临界点的完整相图。

The point at which the incident wave, reflected wave, and mach fronts meet is called the "triple point"

入射冲击波、反射冲击波与马赫波波阵面汇合之点叫做"三相点。"

Firstly, all of univariant line equations are attained; secondly, a crossing point (φ i , pH i ) is got by solving univariant line equations including a main component one another; thirdly,φ i is compared with the chemical potentials φ of other components in this crossing point by chemical potentials minimization.

提出了一种新的绘制φ—pH 图的方法，即先求出所有的单变线方程，再选取某一种组分Mi 为主组分，把含有该组分的所有单变线方程两两求解，求出交点，然后用化学势约束原理法，将主组分同其它组分在该点的化学势作比较，若前者的化学势小于后者，则该点为所求的三相点。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
