| 摘 要： | 对甲基九氟丁醚(HFE7100)在279.15~321.15K温度范围内的液相密度和表面张力进行了实验研究,得到了22组实验数据.利用得到的实验数据,拟合得到了HFE7100的液相密度与表面张力计算方程.密度实验值和拟合方程计算值相比,平均相对偏差仅为-0.00809%,最大相对偏差为-0.00986%;表面张力方程计算值和实验数据之间的绝对偏差在±0.015mN·m-1以内.采用5种理论推算方程对HFE7100的表面张力进行了理论计算,Zuo-Stenby(Z-S)模型计算得出的表面张力值与文中实验值相比误差最小,最大偏差为-1.899%.所获得的密度和表面张力实验数据和计算方程,可为HFE7100的工程应用提供基础热物性数据.

| Abstract: | The liquid density and surface tension of nonafluorobutylmethylether(HFE7100) were measured over the range from 279.15 K to 321.15 K and 22 groups of the experimental data were obtained.These data were used to fit the equations of the liquid density and surface tension.The average relative deviation and the maximum relative deviation between the experimental values and the calculated ones of density were only-0.008 09% and-0.009 86%,respectively,and the absolute deviation between the calculated surface tens... |
