摘  要:本文研究P507(K)-醇(正戊醇、正已醇)-正庚烷-水以及SDS-正戊醇-正庚烷-水四组分微乳液(W/O型)的电导率(σ)与渗透阈值(Ф_p)和渗透温度(t_p)之间的指数规律。得到σ与Ф_p的指数值为s=1.20±0.05,μ=1.20±0.05;σ与t_p的指数值为μ=0.99±0.01。The critical exponential law between the electric conductivity and percolation threshold or percolation temperature of the microemulsion composed of P507(K)-alcohol (pentanol,hexanol)-heptane-wa-ter was studied. It is found that the exponents between conductivity and percolation threshold for mi-croemulsions, namely, P507(K)-alcohol-heptane-water and SDS-pentanol-heptane-water, have same values, i. e. , s = 1. 20 ±0. 05, μ = 1. 20± 0. 05. However, the exponents μ between conductivity and percolation temperature is equal to 1. 00.
