| 摘 要： | 首次利用傅里叶变换红外光谱法对珍珠进行了表征，从碳酸钙红外谱带的位置及形状的变化直接证实了珍珠中亚微米级文石型碳酸钙晶体与有机基质界面之间存在着较强的络合作用。结合ICP-AES成分分析和SEM形貌分析，表明了上述络合作用正是珍珠形成高度有序的层状结构、且具有高强度、高韧性的化学本质。

| Abstract: | Fourier transform infrared spectrometry was firstly used to characterize pearls. The strong complexing interaction between the interface of the submicron aragonite crystals(CaCO 3) and the organic matrix has been directly proved by change of IR band shape and location of calcium carbonate in pearls .Along with composition analysis and micromorphology,it is shown that the above mentioned interaction is the chemical nature of strongly ordered layered structure ,high toughness and intensity of pearls. |
