摘要：

Procedures and design leading to accurate anisotropic diffusion coefficients of water in lyotropic liquid crystals are described. It is shown that, by using simple controls on the important intrinsic and environmental variables, one can achieve subpercent accuracy of the measured diffusion coefficients, The accuracy is tested by comparing results from different diffusion experiments.
