gland

The phenomenon of interference is presented when the x - ray beam hits the thin layer sample at glancing angle , the angles corresponding maximal and minimal intensity of x - ray fluorescence are described when the phenomenon of double - beam interference or multiple - beam interference is occurred 介紹了掠射x射線與薄膜樣品作用時產生的干涉現象,給出了x射線雙光束干涉和多光束干涉產生極值的條件。
