中文摘要	采用XRD、热失重分析、反射光谱及高分辨FE-SEM对青蛤贝壳韧带的矿物组成,结构色及微结构进行系统研究,结果表明:1)青蛤韧带由78%文石矿物,18%的蛋白质及少量的水组成,文石矿物呈纤维状,纤维的直径约138 nm,相邻纤维中心的间距约164 nm;2)韧带可呈现蓝,黄色结构色;3)韧带具有明显的层状结构特征,生长层的厚20μm~40μm,同一生长层中文石纤维长轴定向排列,而相邻层纤维长轴的定向不一致,并呈现一种新的结构类型“-交叉棱柱层”结构。再者,青蛤韧带中的文石纤维构成了一类特殊的2D准周期光子晶体。; The mineral composition,structural color and microstructure of ligament in bivalve shells of Cyclina sinesis were investigated with powder X-ray diffraction,thermal gravity analyzer,reflecting spectrometer and field emission-SEM.The following results were obtained:1) The ligament was composed of minor water,18%(wt) proteins and 78%(wt) aragonite minerals which occur as fibers with about 138 nm in diameter and 164 nm interval between the centers of adjacent fibers;2)The ligament exhibited structural colors of blue and yellow hues; 3)The microstructure of ligament was characterized by growth lamellae with about 20 μm~40 μm in thickness.In each individual growth lamella,the long axes of aragonite fibers were oriented but clearly different from those of adjacent lamella.So,this new type of structure found in ligament was named ″crossed-prismatic layer″ in this investigation.Furthermore,the arrangements of aragonite fibers in ligament of Cyclina sinesis shells constituted a special 2D quasiperiodic photonic crystal.; 国家自然科学基金(50272035); 广西教育厅基金(教科研200420-6)
