摘　　要：The formation and growth of calcium phosphate precipitation pattern were investigated in agar gel system. As an important biologic surfactant, the influence of bile salts on the patterns and composition of calcium phosphate precipitation was discussed. The results indicated that calcium phosphate precipitation shaped the periodic ring pattern in agar gel system. Addition of bile salts will postpone the creation of the periodic ring pattern of calcium phosphate precipitation. NaTC only postponed the creation but not changed the pattern of it. NaC and NaDC not only postponed the creation but also changed the pattern of it. The results of FT IR spectroscopy demonstrated that NaTC have promoted the transformation of calcium phosphate to hydroxyapatite.The formation and growth of calcium phosphate precipitation pattern were investigated in agar gel system.
