摘　　要：用ＮａＣｌ溶液作为影响由直链十二烷基苯磺酸钠（ＬＡＳ）、聚丙烯酰胺和水组成的泡沫体 系稳定性的因素．ＮａＣｌ浓度越大．泡沫体系的稳定性越差．按其稳定性．在ＬＢ槽 上观察各泡沫体 系单分子膜压缩时的膨胀特性．实验表明．泡沫的稳定性与其表面弹性模数有直接的联系．模数ε 越大，泡沫的稳定性越好．This paper puts forward the varity of the concenteation of NaCl acted as factors to affact the stabilization o foam consisted of sodium Dodecylbenzenesulfonate(LAS) and polyacrylamide(HPAM)and water(LAS/HPAM/H2O).Results showed that sodium chloride was harmful for the stabilization of foam. The more sodium chloride concentration was,the Poorer the foam stability would be. According to their different stability,we observed their dilational properties through compressing their monolayers In LB trough. It is proved that the stabilization of foam is closely related to the surface dilational modulus, the higher the surface dilational modulus Is,the better the foam stability will be.
