在金刚石的(100)，(110)和(111)面上分别获得了单晶金刚石膜和金刚石多晶粒子。

Epitaxial diamond films and polycrystalline diamond grain were obtained on (100), (110) and (111) surface of synthesized single-crystal diamond substrates.

就所包含晶粒数相同的多晶集合体来说，在确定晶粒随机取向时，选取不同的方法对它的各向异性程度也有一定的影响。

Even for the same number of grains when taking the different methods to determine the random orientation, the degree of anisotropy of simulated is different.
