晶体习性的形态变化是由于组成晶体的晶面的相对生长速率的差异。对于平衡，面的生长速率与从晶体中心到相应的hkl面的距离成比例。根据BFDH定律，这样的距离与面间距离成反比。因此，观察到的晶面是具有最大晶面间距的晶面。本文试图解释一些特殊的晶体形态推导出的BFDH法律，并表明，晶体的几何形状的影响形态的重要性的面，由于晶体的几何形状，最大的面间距的面不一定是最大的面在BFDH形态。(C)2004 Elsevier B.V.保留所有权利。
The morphological variety of crystal habits is due to differences in relative growth rates of faces of which the crystal is composed. For equilibrium, the growth rates of faces are proportional to the distances from the centre of the crystal to the respective hkl faces. According to the BFDH law, such distances are inversely proportional to the interplanar distances. therefore the observed crystal faces are those with the largest interplanar distances. This paper tries to explain some peculiarities of the crystal morphology deduced from the BFDH law and shows that the crystal geometry influences morphological importance of faces and because of crystal geometry, the faces of the largest interplanar distances are not necessarily the largest faces in the BFDH morphology.
