摘　　要：本文采用激光全息相衬干涉显微术研究了有机非线性光学晶体一水甲酸锂晶体的生长 ,计算了晶体生长的界面过饱和度。我们的研究结果表明 ,晶体生长的界面过饱和度随体过饱和度的增加而非线性增加 ;不同晶面的界面过饱和度不同 ;当体过饱和度增加到一定程度时 。Using holographic phase-contrast interferometric microphotography, the solute concentration distribution was measured during lithium formate monohydrate (LFM) crystal growth at 312.25K in-situ, and the interface supersaturations were calculated. The results show that the interface supersaturation increases nonlinearly with the increase of the bulk supersaturation under a free convection state; different faces have different interface supersaturations at a low bulk supersaturation, and almost have the same interface supersaturation at a high bulk supersaturation for the growth of (021) and (010) faces of LFM crystal.
