crystal axis meaning in Chinese

结晶轴
晶体轴
晶轴线

Not only general suitability of this method is independent of gratings model , geometry structure , medium properly and crystal axis orientation ( including uniaxial crystals and biaxial ones ) , but also physical concepts are clear and formula is concise
该方法不仅不受光栅模型、几何结构、介质性质和晶体取向(包括单轴和双轴晶体)的影响而具有普遍适用性，而且其物理概念清晰、公式简洁。
