【摘要】 本文提出了采用扰流色谱技术［１、２］测定传质系数的原理及计算方法，测定了正己烷、甲醇、乙酸甲酯、丙酮在氮气载气流中的传质系数和扩散系数，并研究了温度、载气流速和搅拌各种参数对测定结果的影响．大量实验结果表明该方法简便、快速、重复性好、准确度高．更多还原

【Abstract】 Flow Perturbation gas chromatography is a new method applied to measure mass transfer coefficients for the evaporation of pure liquids.The necessary mathematical equations were derived and used to calculate the above parameters.The variation of the mass transfer coefficients for the evaporation of some liquids with teh working temperature,the carrier gas flow-rate and other factors was studied.更多还原
