摘　　要：本文详细地研究了胆酸 磷酸 钙三元络合物的结构特性 ,得到一些很有价值的结果。The aim of this paper was to examine the calcium-cholate-phosphate tenary complexes by FTIR spectroscopy. The results indicated that the mole ratio of cholate to phosphate were 1:3 and 1:4 in ternary complexes respectively when the initial mole ratio of cholate to phosphate were 3:1 and 1.5:1 in reaction. The FTIR spectroscopic results demonstrated that in the ternary complexes Ca2+ was coordinated with O in both COO- and PC43- groups.
