光折变晶体用于溶液扩散的研究

Photo-refractive crystal for studying solution diffusion

本文将光折变晶体铌酸锶钡作为全息记录介质,用于测量蔗糖溶液的扩散系数,得到了与文献一致的结果,讨论了实验中应注意的问题。

Using strontium barium niobate photo-refraotive crystal as recording medium, we measured the diffusion coefficient of sucrose solution. The result was in agreement with the data in literature and the experimental conditions were discussed.
