（ 3 ）變生態礦物拉曼光譜的強度很弱、譜線寬而彌散，而退火晶態礦物的拉曼譜峰強而尖銳。In the paper, we describe the whole configuration of the joint transform correlator ; introduce the correlative theories of joint fourier transform in detail ; in order to achieve better correlation result, the nonlinear processing of joint transform power spectrum ( jtps ) is put forward, the effect of jtps laplace sharpening and binary processing to the correlation image is given ; the method of the best binary threshold is determined ; we analyse the correlation image, present the way that removes liquid crystal diffraction spot, direct current spot and image noise, and binarize the correlation image finally
本論文主要對提出的聯合變換相關的整體結構進行了描述；詳細介紹了聯合傅里葉變換的相關理論；為了得到更好的相關結果，本文提出對聯合功率譜進行非線性處理的方法，給出了聯合變換功率譜的拉普拉斯銳化和譜的二值化處理對相關峰圖像的影響及二值化最佳閾值的確定方法；對相關峰圖像信息進行了分析；提出了消除液晶衍射光斑、直流光斑和圖像噪聲的方法；最後對相關峰圖像進行了二值化處理。At the same time, we show that under a proper nitrogen doping concentration, due to the " concentration quenching " effect, the full spectrum of the nn3 center ( i. e., its zero phonon line and various phonon replicas ) is revealed without the interference from the spectra of other higher energy centers ( especially nn4 - nn6 )
Gapi . xn :的發光譜在低組分下由尖銳的nn 。線及其聲子伴線組成，隨著組分x的提高，這些尖銳的的譜線逐漸展寬，並向低能端移動，在這個過程中，激子的能量傳輸起著重要作用In this article, low temperature photoluminescence measurements have been performed on as - irradiated and postannealed n - type 6h - sic, the postannealing temperature is up to 1650 ?. three sharp lines at 478 ^ 483. 3 and 486. 1nm respectively were observed for the first time in the as - irradiated samples and argued to be due to vacancy - like induced by irradiation
對經輻照后未退火的n型樣品的低溫光致發光實驗中，首次觀察到三條尖銳的譜線，分別位於478 . 6 、 483 . 3和486 . 1nm位置，該系列譜線可能與輻照誘生的點缺陷有關。分享友人
