石鳖齿舌牙齿中的磁铁矿物质
Magnetite in the radula teeth of chiton

磁铁矿是地球上非常重要的磁性物质，目前有多种物理化学方法人工合成纳米磁铁矿物质，而生物体内早就存在生物合成的纳米磁铁矿物质. 本文主要就石鳖齿舌主要横向牙齿中的纳米磁铁矿的形貌及合成过程做了描述，可为人工生长一维磁性阵列提供一种很好的借鉴.
Magnetite is the very important magnetic substance in nature, and there are many physicochemical method to artificially synthesize nano-manetite, while there are biosynthesis nano-magnetite existing in the living beings. In this paper, the pattern and synthesis process of nano-magnetite in the radula teeth of chiton are described, this can affords us good lessons to artificially synthesize unidimensional magnetic material
