摘要
通过不同年龄组的釉质标本的红外光谱的分析发现CO_3~2的U_3,U_2振动吸收峰与PO_4^(3-)的U_3振动吸收峰的相对强度的比值随年龄增大而逐渐增大。乳牙和恒牙的红外光谱的分析亦有明显的差异。
Infrared spectroscopic analysis of enamels from different age groups revealed that the ratio of relative intensity between the absorption peak of vibration u_3,u_2 of CO_3^(2-) and the absorption peak of vibration v_3 of PO_4^(3-) increases in parallel with the advancement of ages.Difference in infrared spec- troscopic findings also exists between decidual teeth and permanent teeth.
