有机物偏心因子的计算

Calculation of eccentric factor of organic matter

在根据Riedel蒸汽压方程确定偏心因子计算式形式的基础上,利用物质偏心因子的文献数据,通过非线性回归得出了物质偏心因子关联式;计算了210种有机物的偏心因子,该关联式总平均误差为2.46%,计算准确性优于目前文献各种方法.

Based on Riedel vapor pressures equation, by regression analysis of numerical value of eccentric factor in literature, a correlation of eccentric factor of matter was presented in this paper . The eccentric factor of 210 kinds of organic matter has been calculated by the correlation,the total average error is 2.46%, the correlation is more accurate than calculating method in literature.
