  1. In the third chapter, the influence of current density, solution concentration, erosion time and aging in ambient air on the pl spectra of ps suggests that peak would blue shift with current density increasing, and with erosion time and aging time prolonging ; with the increasing of solution concentration, peaks would red shift when solution concentration less than 1 : 1 but blue shift when solution concentration greater than 1 : 1. above phenomena can be explained by quantum confinement and light center model, but do not deny the action of si - h bonding and defect on the surface in the process of photoluminescence. at present, radiation mechanism is still one of the primary problems in the study of ps

    就反射率的日際變化而言，最大反射率為0 . 24 ，最小為0 . 11 ，相差一倍以上，其峰值均出現在輻射比較強，地表比較乾燥的日期，而谷底一般是在前期降雨較大，表層土壤濕潤時出現。
  4. The infrared results showed that the ir characteristic value l080cm - lof cubic crystal sio, and the absorption peak 460cm - l of mgf, caused by the interaction between f - - mg ' + - p elastic vibration and photon radiation, appeared in the ir spectra. ellipsometric analysis showed that the typical absorption peaks 58lnm, 589nm and 606nm, resulting from the surface plasma resonance of cu panicles and reflecting the absorption on composite film system, appeared in the extinction coefficient k curves of cu ( voll5 % ) mgf, cu ( vol20 % ) mgf, and cu ( vol30 % ) mgf, cermet films, respectively. with the component of cu increasing, the peak site presented red shift, which was in accordance to the results of ultraviolet - visible spectra

  5. At first, we investigated the photoluminescence characterization of theion - implanted samples by spectroanalysis, found that the ion implantation would damage the crystal lattice structure and affect the optical radiation of characteristic. moreover, the crystal lattice structure will be restored after annealing, which can be determined by the change of fluorescence peak intensity and blue migration of wavelength

    發現mn ~ +離子、 c離子的注入都會損傷樣品的晶格結構，從而影響樣品的發光特性，而退火處理對這些損傷有一定的修復作用，這可以從發光峰強度的變化及波長的藍移來判定。
  6. According to this, we propose a new way to renew the traditional method of subjective image quality evaluation, different to only use mse ( mean square error ) and psnr ( peak signal - to - noise ratio ) to evaluate merely on radiation distortion, and complemented quantitative description on compressed image distortion o it is significant to choose the format of video transferation and measuring precision calculation of tracking and measuring systems based on images

    中國科學院長春光機與物理研究所博士學位論文據此提出了不同於傳統的僅用均方誤差（ mse ）和峰值信噪比（ psnr ）來評價圖像灰度輻射畸變的新思路，補充了對壓縮圖像幾何畸變的定量描述。這對于基於圖像的測量跟蹤系統中數字圖像傳輸方式的選擇，以及評價壓縮解壓演算法對測量精度的影響有重要意義。
