使用独特设计的结晶器对蛋壳膜上侧和下侧形成的花状羟基磷灰石团聚物进行了深入研究。首先从理论上计算离子驱动力。此外，利用FESEM、TEM和XRD等手段详细研究了温度、pH值、保温时间等各种因素对团聚体形貌和结晶度的影响。研究发现，在较高的温度、较大的pH值和适度的保温时间下，可以生成高结晶度的花状羟基磷灰石团聚体。产生的信息与骨的形成过程有关。
Flower-like hydroxyapatite agglomerates formed on the upper side and lower side of an egg-shell membrane were intensively investigated using a uniquely designed crystallizer. First the ion driving force was calculated in theory. In addition the influences of various factors, such as temperature, pH value, and holding time, on the morphology and crystallinity of the agglomerates were studied in detail by means of FESEM, TEM and XRD. It was found that flower-like hydroxyapatite agglomerates with high crystallinity can be produced under higher temperature, larger pH value, and moderated holding time. The information generated is relevant to the formation process of bone.
