n.不均匀性；异质性；不同类；多相性
The measurement of refractive index inhomogeneity of optical glass with laser hol lography was presented. 介绍了用激光全息照相测量光学玻璃的折射率不均匀性的方法。
In addition, the cosmic microwave background has some anomalous features that could potentially be explained by large-scale inhomogeneity. 再加上宇宙微波背景有一些奇怪的特征也可能会用大尺度上的不均匀性来解释。
