| 摘 要： | 本文应用能量守恒原理,在一定假设基础上,首次从理论上导出具有一定物理意义的不同温度下液体密度计算公式。对153种液体1632个数据点的计算结果表明,本文公式在很宽的温度范围内(熔点到沸点)具有极高的精确性,优于文献上的其它方法。

NEW METHOD FOR CALCULATING LIQUID DENSITY AT VARIOUS TEMPERATURE WITH HIGH PRECISION |
| |
| Abstract: | Based on the law of energy conservation and certain assumptions, a formulae with some physical siganificance, for calculating the liquid density at various temperature is derived first time. The results calculated for 153 kinds of liquid including 1632 data points show that the formulae has an excellent precision in a wider temperature range (from mp to bp) and is much better than the any other methods published. |
