• 中文摘要： 本文利用基團貢獻的原理，建立一個可以計算溫度在T/sub r/<0.75範圍的有機液體黏度的關聯方法。並以479種有機液體的4,608個實驗數據產生91種官能基的基團貢獻參數。各個基團貢獻參數以五個常數構成，可以用來計算高達 112mPa．S的有機液體黏度。本方法僅需要化合物的臨界壓力，使用上相當簡便。當本方法用來計算4,608個有機液體的黏度時，與實驗數據的標準偏差為 0.16mPa．S,而平均絕對百分偏差是3.86%。同時比文獻中的van Velzen等人(1972)、Orrick與Erbar (1973)、Przezdziecki與Sridhar (1985)的計算方法準確。
• 英文摘要： A correlation method, based on the principle of group contribution, has been developed for calculating the viscosity of organic liquids at temperature T/sub r/< 0.75. Group-contribution parameters of 91 functional groups were obtained by correlating 4,608 experimental data for 479 organic liquids. The various groups are presented as a five-constant equation and can be used to estimate the viscosity of organic liquids up to 112mPa.bcdot.s. The proposed method is relatively easy to use and only requires the critical pressure of each compound. When compared with 4,608 experimental data, this method produces a standard deviation of 0.16mPa.bcdot.s and an average absolute percentage deviation of 3.86%. In terms of accuracy, it compares favorably with the methods of van Velzen et al. ( 1972), Orrick and Erbar (1973), and Przezdziecki and Sridhar (1985).
