摘　　要：本文精确测定了ｐＨ值在１．４～３．０，温度在３００．１５～３１９．１５Ｋ范围内氟铍酸三甘肽（简称ＴＧＦＢ）的溶解度，拟合出溶解度与ｐＨ值的经验方程。用静态体视显微法测定了溶液的ｐＨ值，溶液中杂质离子（ＦｅＦ－３６，ＳｉＦ２－６）浓度及表面活性剂（十二烷基磺酸钠，十六烷基三甲基溴化铵）浓度与ＴＧＦＢ（１１０）晶面生长速率的关系曲线，并进一步讨论了它们的影响机理。The solubility curves of triglycine fluoroberyllate (TGFB) crystal in the condition of pH value 1.4? ?.0 and temperature 300.15—319.15K have been accurately determined,and an empirical formula has also been summed up by curve fitting. The relationship curves of pH value of solution, concentration of inorganic impurity (FeF 3- 6,SiF 2- 6), and concentration of surfactants (sodium dodecyl sulphonate,cetyl trimethylammonium bromide) with the growth rate of (110) crystal face were determined by stereoscopic microscopy, and the affecting mechanism of medium on TGFB crystal growth was discussed.
