【摘要】 色谱法测二元系有限浓度活度系数,其数据处理据文献报道,用差分法步骤繁琐。本文将原始微分方程中Q项与y,用实验数据回归求解。不仅计算大为简化,而且提高了精度。更多还原

【Abstract】 One of the methods to calculate the binary finite activity coefficients measured by chromatography is using the finite difference method which is overlaborate. This work solves the Q term and y values in the original differential equations by regression of experimental data. As a result, the calculation procedures are not only simplified, but the precision is also improved.更多还原
