摘　　要：本文提出了一个反映表活剂在等温条件下损耗特性的数学表达式。The losses of sodium petroleum sulfonates in laboratory experiments reach their equilibrium value quickly and go through a maximum as the concentration of aqueous sulfonates solution is increased, thus the phenomena can not be described satisfactorily by a Langmuir type equation. In this paper a two-parameter equation in form of gamma funcfion is constructed as a result of linear regression analysis (l.r.a.) on computer of a series of experimental data published. It is obtained as.(?)=(?)^(vb)exp b(1-(?)~v), in which (?)=S/S_m and (?)=C/C_c, where S denotes the sulfonate loss at solution concentration C, S_m—the maximum loss observed generally at apparent micellat concentration C_c, v and b—two controllable parameters determined by try and error method in the l.r.a, process.
