函數(shù)和shell腳本的妙處之一是，通過向單個函數(shù)或腳本傳遞參數(shù)能夠使它們表現(xiàn)出不同的行為。

　　Part of the beauty of functions and shell scripts is the ability to make a single function or script behave differently by passing parameters to it.

　　納米SiO2的獨特結構使其表現(xiàn)出一些特殊的光學特性，但文獻對其紫外區(qū)光學性質的報道不一致。

　　The unique structure of nano SiO 2 makes it show some special optical properties. However, the reports about it's optical properties in ultraviolet region are different.
