The main results of this thesis can be summarized as follows : 1. based on the huygens - fresnel principle, we have derived the propagation expressions of the partially coherent beams passing through an annular lens optical system. the influence of the spectral degree of coherence, fresnel number and truncated parameter on the focused intensity distribution and focal shift is analyzed
主要工作包括: 1 .從惠更斯-菲涅耳原理出發，推導了部分相干光束通過環形透鏡系統的傳輸公式，分析了空間相干度、菲涅耳數、攔截系數對系統中光束的聚焦光強和焦移的影響。 -
Abstract : after reading two papers, spectral blue shift of themal radiator and some problems related to it in infrared physics and a discussion on spectral blue shift of thermal radiator, some doubts on measurement were presented. spectral blue shift was in process, which is not against the three thermal dynamic laws
文摘:看了《紅外物理中熱輻射的光譜「藍移」及與之有關的問題》和《熱輻射光譜「藍移」問題的商榷》兩文，本文對其測試條件提出質疑，並著重闡述了光譜發生「藍移」是「過程中」的現象，並不違反熱力學三定律。 -
Spectral shift of partially coherent spatial soliton
部分相干空間孤子的頻移 -
Detailed emission and excitation spectral characteristics have been analyzed and discussed. in addition, spectral red - shift has been found in both charge transfer bands in nanocrystalline y2o3 : eu 3 + compared to the bulk material. the number ratio of s6 sites to c2 sites is also smaller in nanocrystalline y2o3 : eu3 + than that in the bulk one
與體材料相比，兩種格位的電荷遷移帶在納米材料中都發生紅移；相對于c _ 2格位的電荷遷移帶， s _ 6格位的電荷遷移帶強度在納米材料中比在體材料中明顯降低。 -
The calculated density of mgf2 with iad was increased from 0. 70 for conventional process to 0. 97. meanwhile we find that the spacer layer has a great influence on the spectral shift. the further the layers are away from the spacer, the less the effect ; in the same way, the iad reduces the spectral shift of nb205 / sio2 narrow band interference filters from 29. 4nrn to 12. 4nm ; the iad reduces the spectral shift of tio2 / sio2narrow band interference filters from 24. 7nm to 8. 4nm
同時發現間隔層對光譜漂移的影響最大，越遠離間隔層的膜層，其影響越小；而nb _ 2o _ 5 sio _ 2多層膜窄帶干涉濾光片漂移從常規工藝的29 . 4nm降到12 . 4nm ； tio _ 2 sio _ 2多層膜窄帶干涉濾光片漂移從常規工藝的24 . 7nm降到8 . 4nm 。 -
Blinking of the sers spectra and the poisson statistical distribution of the raman signal were observed. moreover spectral diffusion of raman shift with time was reported by the first time according to our knowledge, which could be due to the difference of interaction between varied single molecules and varied silver particles surface, for instance, due to the different adsorption states of dab molecules on the silver surface, which should be a powerful evidence for single molecule detection by sers
我們採用一種簡單的方法，將含有dab分子的銀膠體溶液滴在鋁箔上，激發光聚焦在液滴上直接進行測量，觀察到了分子sers信號的「 blinking 」現象，並首次報道了其sers拉曼頻移隨時間產生波動，這是由於個體分子和銀納米顆粒的相互作用及其在銀納米顆粒表面的l吸附狀態不同而導致的。 -
The typical result shows that the spectral shift of zns / mgf2 narrow band interference filters is less than 0. 5nm. the formula for estimating packing density of the films was put forward in terms of the measured. and the packing density of mgf2 layers in the filters was calculated
計算了濾光片中mgf _ 2膜層的聚集密度，離子輔助使mgf _ 2的聚集密度從常規條件下的0 . 70提高到0 . 97 ，增幅達38 。
