摘要
考虑到吸附膜与单分子不溶膜的相似性，在不溶膜研究中引入分子间相互作用参数β，用以讨论不溶膜中的非理想性问题．对“６２０１”／Ｃ＿（１８）ＳＯ＿４Ｎａ体系得到了一个与临界值２．０接近的β值，进一步验证了该体系存在相分离的推测．
In consideration of the similarity of insoluble monolayers and soluble monolayers,amolecular interaction parameter(β)was introduced to describe the nonideality of the mixedinsoluble monolayers. From the surface pressure-area isotherms of “6201”/C_(18)SO_4Na mix-tures,a high molecular interaction parameter which was closed to the critical value 2.0 wasobtained,which has further verified the previous guess that a phase separation took place ata higher surface pressure.
