扫描电子显微镜在鹌鹑蛋壳表征中的应用

Application of Scanning Electron Microscopy in Quail Eggshell Characterization

利用扫描电子显微镜对鹌鹑蛋蛋壳的横截面、内外表面进行观察,蛋壳由内向外分别是壳膜、乳突层、海绵层、垂直晶体层和角质层.外表面分布有深褐色、浅黄色的不规则颜色斑点,深褐色区域比浅黄色区域的角质层厚,其差异来自于角质层.对深褐色区域与浅黄色区域进行外表面能谱分析,深褐色区域的C、O和N元素含量相对高于浅黄色区域,浅黄色区域的Mg、P、S和Ca元素含量相对高于深褐色区域.

The microstructure of the outer surface and cross section of quail eggshell has been observed using a scanning electron microscope(SEM). The results showed that the quail eggshell was composed of shell membrane, mastoid layer,sponge layer, vertical crystal layer and stratum corneum from inside to outside. The outer surface was distributed with dark brown and light yellow irregular color spots. The stratum corneum in the dark brown area was thicker than that in the light yellow area. The difference comes from the stratum corneum. The energy spectrum results showed that the contents of C, O and N in the dark brown area were relatively higher than those in the light yellow area, and the contents of Mg, P,S and Ca in the light yellow area were relatively higher than those in the dark brown area.
