能譜展寬
英文
broadening of energy spectrum-
At the same time broaden the spectrum as result of energy loss fluctuations.
與此同時,電子譜由於能量損失的漲落而展寬。The results displayed that the spectra were wider than that of one single dye and there were energy transfer between c102 and rh6g. in silica films the energy transfer efficiency was higher than that in ethanol solutions
C102 : r上6gh元混合染料間存在著能量傳遞,將其摻雜到isio 。凝膠中,發現與無水乙醇溶液中相比;能量轉移效率增加,光譜i展寬,原因可能是出。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According to the current problems such as low quantum efficiency. limited available sun energy spectrum range, and inefficient recovery, resulted from the practical using of photocatalysis, using the narrowband semiconductor cds ( eg = 2. 5ev ) to compound with tio2 seems to be an effective solution. since it will not only enlarge the region of the absorption with the proper narrow band of cds but also improve the photodegradation efficiency on account of the band overlap of the two, which makes the photo induced electron and holes separate more easily
本文針對光催化技術應用中存在的tio _ 2光催化量子效率低,吸收利用太陽能光譜范圍有限,催化劑回收困難等問題,通過窄禁帶半導體cds ( e = 2 . 5ev )的復合,對納米tio _ 2進行了改性研究,一方面,由於cds的窄禁帶寬度可以擴展薄膜的光譜吸收范圍,另一方面,由於能帶的交疊,提高了光生電子和空穴的分離效率,從而提高了薄膜的光催化降解效率。In recent years, radio technology has developed very quickly in our country. however, a radio monitoring receiver with broad frequency scale ( 20 - 3000 mhz ), high scanning rate ( above 1ghz / s ) and whole spectrum real - time display has not developed. some imported monitoring receivers with broad frequency scale can only scan slowly and could n ' t meet actual needs. not only these imported receivers " price is high but also those developed countries usually limit the quantities of imported receivers and related technology is not open
近年來我國無線電技術水平已經有了很大發展和進步,但對于頻率覆蓋范圍寬( 20 - 3000mhz ) 、掃描速度快( 1ghz / s以上)並具備快速全頻段實時頻譜顯示和記錄的無線電監測接收設備,目前我國尚不能生產,國內現在已經進口的寬頻段監測接收機一般也只能進行低速掃描,無法滿足實際的需要。The 0 - 15kev energy slow - positron beam was used to measure the dopple broadening in sio2 / sic. both the s and w parameters clearly showed that the density of defect in sio2 layer had decreased after annealing in n2
利用0 - 15kev的慢正電子多譜勒能量展寬測試sio _ 2 sic的缺陷情況,發現不管是n型還是p型,氧化層附近其s參數經過n _ 2退火明顯減小, w參數在這個部位增大。The research on spectral signal analysis is useful to advance performance of spectrometer and extend application range of spectrometer
開展這方面的研究,對提高微型光譜儀的性能,拓寬應用范圍都有著重要的理論和現實意義。This is by two reasons : the first, as the development of military communication technologies, it transit from digital to software implementation, intelligence, broad band implementation and network implementation. many new technologies such as adaptive frequency hopping, burst communication, broadband modulation and complex coding accelerate the research about pertinence algorithms of signal sense and signal processing. the second, three hotspots of modern signal processing - spectrum estimation, high - order statistics ( hos ) and time - frequency analysis theory become more and more consummately and being used in communication jamming and anti - jamming field
應用於軍事通信對抗的信號處理理論發展非常迅速,這得益於兩個方面的動力:其一,軍事通信的技術和手段不斷更新,在數字化的基礎上逐步走向軟體化、智能化、寬帶化和網路化,出現了自適應跳頻、突發通信、寬帶調制和復雜編碼等新的實用技術,推動了具有很強針對性的信號偵測和處理領域的演算法研究;其二,現代信號處理的三大熱點? ?譜估計、高階統計量方法、時頻分析的理論和技術日臻完善,並逐漸應用於通信對抗領域。分享友人
