摘要
用干涉测量法测定了若干条件下蔗糖溶液的扩散系数Ｄ。并测定了表面活性剂对Ｄ值的影响。当温度为１５．５℃（室温）时，浓度为５％的蔗糖溶液的Ｄ值为４．６２×１０^（－６）ｃｍ~２／ｓ。相同条件下含有１％表面活性剂的蔗糖溶液的Ｄ值为３．７３×１０^（－６）ｃｍ~２／ｓ。结果表明表面活性剂可降低蔗糖溶液的Ｄ值。
The diffusion coefficients of sucrose solution and the effect of surfactant were measured with holometric method. The results show that the diffusion coefficient D can be reduced from 4. 62x10￣(-6) to 3. 73 x10￣(-6) cm￣2/s with the addition of 0.1 % surfactant at 15. 5℃ and 5% sucrose solution.
