主题：【求助】如何从XRD判断晶面的择优生长

      在论文《Intrinsic Dipole-Field-Driven Mesoscale Crystallization of
Core Shell ZnO Mesocrystal Microspheres》JACS，2009,131,9405-9412.作者通过XRD判断了ZnO晶面的择优生长。原文如下：

      We have found that  the relative intensity ratios of the (100)/(002) and (101)/(002) reflections are larger than the standard values in the JCPDS card
no. 36-1451, especially for the (100)/(002) ratio, indicating preferential orientation growth in the (100) direction.
      1.问：对于ZnO，可以通过这种方法判断出来晶面的择优生长吗？使用峰强比值来判断晶面的择优的生长，这是一种通用方法吗？
   
    Further-more, detailed analysis of the peak broadening using the Scherrer equation shows the coherence lengths of Dhkl of the (100) and (002)
reflections to be D100 37.5 nm and D002 15.1 nm. D100 is larger than D002 and the D100/D002 ratio is 2.45.
      2.问： 通过谢乐公式，可以求出相干长度吗？对于相干长度，它对晶体生长有判断帮助吗？
   
  According to the calculated ratio, it is expected that the primary crystallites will take up a sheet- or plate-like shape in the final ZnO superstructure.
  3.问：如何通过计算，可以得出ZnO形状？
 
    我是刚刚接触晶体，对这些十分不了解，请各位朋友帮忙回答一下，万分感谢！！
