摘　　要：以乙酸乙酯对正庚烷的相对摩尔响应值（Ｓ＿Ｍ）为例，研究了Ｎ＿２，Ｈ＿２流速对Ｓ＿Ｍ的影响，得到了回归方程并求得了最佳操作条件。he effect of hydrogen and nitrogen flow rates on relative molar response(RMR)of ethyl acetate withrespect to n-heptane was investigated by regression analysis.For small sainple size the nitrogen and hydro-gen flow rates have nn effect on RMR,But for larger sample size an equation which best fits the experimentaldata was achieved,in which the effect of flow rate ratio of nitrogen to hydrogen on RMR was revealed.Anoptimum ratio of flowrate of nitrogen to hydrogen was obtained from regression equation,under which RMRis independent of sample size.
