If they have the X-ray powder diffraction patternsof materials, even if being non-expert on X-ray crystal structure, they can conveniently get the index of diffraction lines and cell parameters.

对于非专业X 射线晶体结构人员，只要得到材料衍射图谱后，能很方便计算点阵常数和衍射线指标化。

This article based on the MTN, and put emphasis on the parameters of liquid crystal display (LCD), such as the elastic constants, dielectric constant, pretilt angle and cell gap.

本文主要针对MTN模式设计，着重关注液晶弹性常数，介电各向异性，预倾角度，以及盒厚变化对显示效果的影响。
