文摘:討論了在雙光子驅動場作用下,三能級原子在光子晶體中的自發發射問題.由於量子干涉和光的局域化作用,兩個上能級中的占據數將具有周期振蕩或準周期振蕩的性質,這不僅依賴于兩個上能級與禁帶的相對位置,同時也依賴于原子的初始狀態,而且還與驅動場的強度、驅動場的入射位相有關.這些性質既與真空中帶有驅動場的原子的自發發射性質不同,也有別于無驅動場作用下光子晶體中三能級原子的自發發射性質One can discover other spiritual themes and imagery in andersens works as well. for example, the following passage from the story the bell 1845 suggests that the author experienced some degree of enlightenment : the whole of nature was a large holy church, in which the trees and hovering clouds formed the pillars, the flowers and grass, the woven velvet carpet, and heaven itself was the great cupola ; up there the flame color vanished as soon as the sun disappeared, but millions of stars were lighted ; diamond lamps were shining, and above them sounded the invisible holy bell ; happy spirits surrounded them, singing hallelujahs and rejoicing
我們在安徒生的作品中還可以發現一些靈性題材和意象,例如,以下節錄自故事鐘聲1845年發表的一段文字,透露了作者某種程度的開悟體驗:整個大自然就是一座神聖的大教堂,以樹木和浮雲為樑柱,以群花和綠草為絲絨地毯,而穹蒼就是它遼闊的屋頂,在那裡太陽一隱身,五彩光輝便隨之消逝,繼而亮起繁星點點,鉆石般的燈火閃閃發光,無形的神聖之鐘從上方傳來陣陣鐘聲,快樂的精靈圍繞著它們,唱著充滿喜悅的頌歌。Milk nutrient extract : pure milk contain abundant levo - vc, effectively and deeply nourish and hydrate skin, smoothen fine lines, improve rough pore, leave skin bright, young, firm and elastic
