Preferred orientation in the shell of the domestic fowl is shown by x-ray diffractometry to develop gradually throughout the shell, beginning immediately after the start of shell deposition and reaching a maximum at the exterior surface. Only 2 out of 20 shells examined exhibited a single preferred orientation: This was one in which the pole of the (001) plane lies parallel to the shell surface normal. The remaining shells had two preferred orientations present simultaneously, one in which the (001) pole is parallel and the other in which the (104) pole is parallel to the surface normal. Previous work has resulted in conclusions that are in conflict with these; they are discussed in relation to the present work.
通过X射线衍射测定法表明,家鸡蛋壳中的择优取向在整个蛋壳中逐渐形成,从蛋壳沉积开始后立即开始,并在外表面达到最大值。在检查的20个蛋壳中,只有2个呈现单一的择优取向:即(001)面的极平行于蛋壳表面法线的那种取向。其余的蛋壳同时存在两种择优取向,一种是(001)极平行,另一种是(104)极平行于表面法线。先前的研究得出了与这些结果相矛盾的结论;将结合当前的研究对它们进行讨论。
