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 axis crystal.

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；

We study the beam paths in uniaxial crystal with arbitarily oriented optical axis in general conditions, by it′s plane and ellipsoid of refraction index and Fresnel law.

从菲涅耳定律出发，利用单轴晶的折射率面和光率体，讨论了在一般情况下单轴晶内部的光路问题。

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

利用二轴晶的光波面，对光轴与光线轴的关系进行了研究。

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。

We intentionally render the rotational axis of growing crystal to deviate from the symmetry axis of the temperature field, the temperature fluctuations with sinusoidal form in meniscus are produced.

使晶体转轴与温场对称轴不一致，则在晶体弯月面内会产生随时间变化的正弦波式的温度分布。
