依据生物矿化的基本原理，以β－环糊精（β－CD）作为有机基质，采用仿生 的方法合成了具有独特形貌的文石型碳酸, 其中含有少量的β－环糊精。用X射线 粉末衍射（XRD）分析、扫描电子显微镜（SEM）、傅里叶变换红外吸收光谱（FT－ IR）和电导率测定等手段对所得复合碳酸钙进行了表征，结果发现CaCO3结晶过程 中，β－环糊精与CaCO3之间存在着相互作用，并讨论了这种作用的可能机理。

Based on the basic principles of biomineralization, a novel aragonite (CaCo_3) with specific morphology was synthesized under the control of-cyclodextrin by the biomimetic method. In our experiments, the β-cyclodextrin were used as the organic matrix. The obtained composite CaCO_3 with small amount of β-cyclodextrin were characterized by X-ray powder diffraction (XRD) analysis and scanning electronic microscopy (SEM). Furthermore, according to the results of Fourier transform infrared spectroscopy (FT-IR) and measurement of conductance ratios, the possible mechanism of the interaction between β-cyclodextrin and CaCO_3 during the CaCO_3 formation process was discussed.
