摘　　要：本工作用实验方法研究了两种阴离子表面活性剂溶液经磁场处理后物理化学性质的变化。发现溶液表面张力普遍下降,一般约下降10%以上。这种变化具有弛豫性,至少可维持一周时间,甚至更长。本文对此作了详细报道。More recently,magnetic technology has been used for oil recovery in China.Our interest is concentrated both on its practical applications and theoretical aspects:why the weak magneti fields can make some properties of water changing and how these changes make oil recovery more efficient.It is for this reason,we have started to investigate this project supported by Petroleum Ministry and Academia Sinica.In this paper,changes of surface tensions of sodium p-toluenesulfonate and sodium dodecylsulfonate solutions treated mag- netically have been measured.Results obtained experimentally show that the surface ten- sions of magnetically treated surfactant solutions are decreased by about 10% in comparison with that of untreated ones.The changes of surface tensions can be retained for more than one week.The recovery of the changed surface tensions to their initial values is therefor a relaxation process,which depends strongly on the surfactant structure and the circumstances.
