【摘要】 本文主要用X-射线衍射法和偏光显微镜观察,对来杭鸡胚胎发育中卵黄囊内的晶态物质—囊球晶作了观测研究,发现其基本成分为CaCO₃,结构为球霰石和方解石型,扫描电镜的观察则给出了囊球晶的众多的亚微观结构形态。文中最后对其意义作了初步讨论。更多还原

【Abstract】 The egg yolk sac spherocrystal emerged in period of the embryo developing of Lai-hang chicken has been studied by X-ray diffraction and polarized light microscopy. The result indicated that egg yolk sac spherocrystal is essentially made up of CaCO3, with the structure both vaterite and calcite. A great amount of sub-microstructure of egg yolk sac spherocrystals have been observed using scanning electron microscope (SEM) . Finally, the significance of the results has been discussed preliminarily.更多还原
