X - ray diffraction at three points along the hair showed clear evidence of the ring at the position furthest from the hair root, a fainter ring at the middle point, and complete absence of the ring close to the root
線衍射在頭發的3處部位出現：清楚的環是在頭發根部的遠端出現；弱環是在頭發的中部出現；在頭發根部則沒有環出現。 -
Fraunhofer - diffraction of the similar circular ring
類圓環的夫瑯和費衍射 -
Used as ring - down cavity, this stable resonator has, firstly, more influence of misalignment of cavity mirrors on its measured reflectivity, but less of length misadjustment ; secondly, shorter cavity length which advantageous in engineering ; finally, less diffraction loss and thus higher metrical precision
結果表明，這種穩定腔用作衰蕩腔，測量結果受腔鏡角度失調影響較大，而受腔長失調影響小；其長度較短，便於工程應用；衍射損耗較小，測量精度高。
