摘要：

The effective diffusion coefficient of ethanol in a 4 %(w/v) agarose gel at 25-degrees-C was measured using a diaphragm diffusion cell. The reproducibility was very good; a standard deviation of only 2% was obtained. The mean value (9.5 x 10(-6) cm2/s) agreed well with available theory and previous investigations.
