Study on uv-light induced photodegradation of 17-ethynylestradiol in aqueous solutions 雌二醇水溶液紫外光降解的研究
The sweet music and dim lights induced in the couple a feeling of euphoria 甜美的音樂(lè)和朦朧的燈光激起這對(duì)戀人歡快的感覺(jué)。
The result shows that with increase of teos content, the transmittance in the visible region of the hybrid materials decreases, uv light induced aging-resistance of the hybrid materials increases 結(jié)果表明,隨著teos含量的增大,雜化材料在可見(jiàn)光區(qū)域的透光率有所降低,耐光老化性相應(yīng)提高。
Inversely, when kt was present in the medium the light induced inhibition was also decreased . it is an independent process of light and kt on inhibition of hypocotyl elongation and they showed multiplication effect on the process 不同光質(zhì)下可降低kt對(duì)下胚軸伸長(zhǎng)的抑制效應(yīng);反之,kt的存在也降低了不同光質(zhì)對(duì)下胚軸伸長(zhǎng)的抑制作用。
Although several reports have been published for the components involved in signaling pathway of light-controlled pigmentation, evidence of extracellular ca2 + and cam involved in blue light induced anthocyanin accumulation and chs expression is still limited 盡管對(duì)藍(lán)光誘導(dǎo)的反應(yīng)機(jī)理和信號(hào)轉(zhuǎn)導(dǎo)途徑已有一些研究,但對(duì)胞外鈣離子和鈣調(diào)素(cam)是否參與反應(yīng)仍不清楚。
By measuring the ultraviolet-light-induced absorption coefficeint change, we believed that the ultraviolet-light induced absorption changes were ascribed to the generation of the small polarons o ( superscript-) under the illumination of uv lights 通過(guò)對(duì)不同組份摻鎂鈮酸鋰晶體紫外光致吸收的動(dòng)態(tài)暗衰減過(guò)程的測(cè)量,我們認(rèn)為摻鎂鈮酸鋰晶體中紫外光致吸收的淺能級(jí)缺陷中心是o(上標(biāo)-)小極化子。
Moreover, azo dyes find wide applicability in reversible optical data storage . the storage process utilizes the light induced trans-cis-trans isomerization of the azo dye, thereby utilizing the local variation of the refractive index of the medium 另外,偶氮類染料在可逆的光信息存儲(chǔ)(全息和數(shù)字)得到廣泛應(yīng)用,存儲(chǔ)過(guò)程就是利用光致偶氮類染料的反式?順式?反式的異構(gòu)化過(guò)程,從而利用介質(zhì)折射率的局部變化來(lái)進(jìn)行存儲(chǔ)。
39 % of total conversion efficiency at pump level of 600mw 858nm is obtained experimentaily with our single-resonant, external ring frequency-doubler pumped by tr . sapphite laser at room temperature ( about 21.50c ) . the conversion efficiency is seriously limited by what is called " blura " ( blue light induced infrared absorption ) and thermal effects . yet, up to 137 mw of cw blue light at 429nm at pump level of 565 mw has been achieved and stabilized over a hour when the cavity is locked via pound-drever-hall ( pdh ) technique 泵浦功率為600mw時(shí),由于兩種效應(yīng)“藍(lán)光導(dǎo)致紅外吸收(bliira)”和“熱效應(yīng)(thermaleffects)”的嚴(yán)重影響,室溫下(約21.5)獲得了39的倍頻轉(zhuǎn)換效率;采用邊帶鎖頻技術(shù),565mw的泵浦光獲得137mw的藍(lán)光輸出,在沒(méi)有外界強(qiáng)烈的干擾下可以鎖定1小時(shí)以上而不失鎖。
