中文拼音 [zhǎidàixīshōu]
窄帶吸收
英文
narrow-band absorption-
( 4 ) the results of ftir showed that the ftir spectrum of decaying remainders at all periods was near to that of original samples, and was far to that of soil humus
（ 4 ）紅外光譜分析結果，腐解物原樣的紅外光譜各主要吸收帶均較窄且強度較大，而腐殖酸的紅外光譜各主要吸收帶均較寬且峰尖平緩。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。( 3 ) ln the fourth chapter of this dissertation, a tunable single - longitudinal - mode erbium doped fiber ring laser is achieved by using the very narrow bandpass characteristics of the self written grating formed in a section of erbium doped flber withoat undergoing pumping by stable standing wave in it. tl1e tunable laser ' s wavelength tuning range is 40nm, from l 523. 79llm to l563. 92nm
三、在本文第四章，利用駐波干涉和飽和吸收誘發的自寫入光纖光柵的窄帶濾波特性及反射波長自適應特性，研製成可調諧摻鉺光纖環形腔單頻激光器，其波長連續可調諧范圍達40nm （ 1523 . 79nm ?安激大學碩士學位論文摘要1563Road vehicles - electromagnetic compatibility test procedure of automotive components - part 5 : qualification of the immunity to narrowband interference according to theabsorptive chamber procedure
道路車輛.汽車組件的電磁兼容性試驗規程.第5部分:根據吸收室規程進行抗窄帶干涉性的合格鑒定Eight samples of erythrocytes in bone marrow coming from patients affected by acute myeloid leukemia and nine samples from patients suffered from chronic myeloid leukemia were studied by ftir spectroscopy. spectroscopic differences of leukemic erythrocytes were observed between aml and cml samples. the ratios of the integrated areas of the band at 1540cm
研究了急性粒細胞白血病aml和慢性粒細胞白血病cml患者的骨髓血紅細胞的紅外光譜差異性：與cml紅細胞相比， aml紅細胞酰胺帶較寬1540cm - 1與1 084cm - 1吸收峰面積之間的比值較低，范圍較窄。Because of the anatase ' s broad eg ( 3. 2ev ), the absorption thresholds correspond to 380nm for the tio2. consequently, only the ultraviolet fraction of the solar irradiation can be active in the photoexcitation processes using pure tio2 solid. the high recombination rate of charge carrier and low efficiency of quantization are also the deficiencies of pure tio2
由於tio _ 2的帶隙較寬（約3 . 2ev ） ，半導體的光吸收波長范圍窄（主要在紫外區） ，故其太陽能的利用效率低，且還存在半導體載流子的復合率高，量子化效率低等缺陷。分享友人
