This is due to the different surface properties between a cleavage face and a crystal face. The non-saturated bonds on a crystal face must be readjusted during the growing and the late period. So the growth activation of a crystal face is low at the beginning stage. However, a cleavage face is cleaved artificially and recently. There are many non-saturated bonds on it and these non-saturated bonds can accelerate the growth rate.

其原因是：晶面不同于解理面，晶面上的悬键已在生长过程和后期过程中经过调节达到了新的平衡，所以晶面在初始时期的生长活性很低；但解理面是人为破裂形成的，其上的悬键未能达到平衡，所以解理面的生长活性是很大的，导致其生长速度非常快。

This law needs to watch the trend of the step on face of CdSe crystal cleavage only, can determine the C axis direction of CdSe crystal, namely the C axis direction that the direction with the outspread step on cleavage face is CdSe crystal, used law of X ray diffraction to undertake test and verify to the result.

此法只需观察CdSe晶体解理面上台阶的走向，便可确定CdSe晶体的C轴方向，即解理面上台阶延伸的方向为CdSe晶体的C轴方向，并采用X射线衍射法对结果进行了验证。

For example, alkaline elements can affect diffusion velocity of Zr, Si and O ions although these alkaline elements cannot exist in crystal structure of zircon. However, K rich media and Na rich media exert different effects on the growth of crystal form: in the K rich media, growth speed of prism faces in the vertical direction is much higher than that of pyramid faces, and {111} growth speed in the vertical direction is higher than {311},which decides the formation of bipyramids dominated by {311} pyramids; in the Na rich media, both prism and pyramid grow to a certain extent, but the former is smaller than the latter.{100} growth speed in the vertical direction is lower than {110}, while {111} growth velocity in the vertical diredtion is lower than that of {311},resulting in the growth of the crystal form characterized by {100} short prism and {111} pyramid.

例如，尽管碱性元素并不进入锆石晶格，但它们可以影响Zr、Si、O离子的扩散速度，但是富钾和富钠的介质对锆石晶形发育的影响是有差别的，表现为：在富钾的介质中，将导致柱面的法向生长速度较锥面快得多，而锥面中，｛111｝的法向生长又较｛311｝快，由此决定了形成以｛311｝锥为主的双锥状晶体；在富钠的介质中，柱面和锥面都有一定程度的发育，但前者弱于后者，而柱面中，｛100｝的法向生长较｛110｝慢，由此决定了形成以｛100｝柱和｛111｝锥为主的短柱锥状晶体。

Based upon a point-charge plus point-dipole model, the crystal-field splitting parameters for α-TiCl3 layer crystal and β-TiCl3 fiber-shaped crystal were evaluated and estimated, respectively, and the results were used to interprete the diffuse-reflectance spectra of these crystals recently reported in the literature.
