Recently, the results of experimental and theoretical investigations have revealed that, in vaterite, two or even more crystalline structures coexist. In this communication we report evidence of diverse vaterite structures in biogenic samples of different origin. In addition, it is shown that the synthetic vaterite precipitated in the presence of poly-l-aspartate has structures similar to those of biogenic samples.
最近，实验和理论研究结果表明，在球霰石中，两种甚至更多的晶体结构共存。在本通讯中，我们报告了不同来源生物样品中存在多种球霰石结构的证据。此外，研究表明，在聚-L-天冬氨酸存在下沉淀的合成球霰石具有与生物样品相似的结构。
