通过透射电子显微镜和扫描电子显微镜在珍珠层的有机基质层中直接观察和测量了生物矿化中称为矿物桥的纳米结构类型。统计分析给出了有机基质层中矿物桥的几何特征和分布规律。实验表明，纳米结构显着影响的有机基质层的机械性能。力学分析表明纳米结构对有机基质层行为的影响，分析结果较好地解释了相应的实验现象。研究表明，矿物桥对珍珠层有机基质层的力学性能起着关键作用。所得结果对合成材料的界面设计具有指导意义。(C)2003爱思唯尔科技有限公司。保留所有权利。
The type of nanostructure referred to in biomineralization as a mineral bridge has been directly observed and measured in the organic matrix layers of nacre by transmission electron microscopy and scanning electron microscopy. Statistical analysis provides the geometric characteristics and a distribution law of the mineral bridges in the organic matrix layers. Experiments reveal that the nanostructures significantly influences the mechanical properties of the organic matrix layers. In addition, the mechanical analysis illustrates the effects of the nanostructures on the behaviors of the organic matrix layers, and the analytical results explain the corresponding experimental phenomena fairly well. The present study shows that the mineral bridges play a key role in the mechanical performances of the organic matrix layers of nacre. The results obtained provide a guide to the interfacial design of synthetic materials. (C) 2003 Elsevier Science Ltd. All rights reserved.
