It indicates that the direction of ray axis and optical axis is identical by discussing the uniaxial crystal at last.
最后对一轴晶进行了讨论，结果表明此时光轴方向与光线轴方向一致。

The results show that the grain size of produced ZA20, ZA27 alloy powder for cold spray is homogeneous, and the phase of the coat is equal axiscrystal.
研究结果表明，制备的冷喷涂用ZA20、ZA27合金快凝粉末粒度分布均匀，组织为细小的等轴晶；

The relation of ray axis and optical axis is discussed by using the optical wave camber of biaxial crystal.
