The ohio state chemists determined that , when excited by ultraviolet light , these three bases dissipate energy through the dark state anywhere from 10 - 50 percent of the time 俄勒岡州化學家認為,在紫外光刺激下三種堿基在10 % 50 %時間內通過”黑暗狀態“轉移能量到各處。

Because these forms of radiation have much shorter wavelengths than the ultraviolet light currently used in photolithography , they minimize the blurring caused by diffraction 由于這類型輻射的波長遠較現在光蝕刻使用的紫外光來得短,因此可以減少因繞射而造成的模糊。

In addition , the authors study ultraviolet light response of sodium titanate nanowire - based devices and find that uv light may induce a large photoconductivity 另外,還研究了紫外光uv照射納米線對器件電學特性的影響,發現紫外光可以使納米線產生很大的光電導。

If you want to combat your skin ' s biggest enemy , ultraviolet light , then artistry has the answer . the pure white system is the best way to beautiful skin 要全面對抗美白肌膚的大敵人?紫外光,雅姿的美白系列能日夜呵護您白皙幼嫩的肌膚!

If the experiment calls for measurements in the ultraviolet , the cuvette holder can be optimized to more efficiently transmit ultraviolet light 如果實驗要求在紫外線區域進行度量,那么可以優化小型管固定器使其更有效的傳輸紫外光。

Then , by measuring the total amount of rest - frame ultraviolet light , researchers can estimate the number of high - mass stars in the galaxy 然后,經由測量靜止座標光譜中紫外光的總量,研究人員就能夠估計該星系里大質量恒星的數目。

Others have created skin - tissue cultures that glow colourfully under ultraviolet light by splicing in a gene from a species of coral 另一些則發明了表皮組織培養技術,通過導入珊瑚的基因使其在紫外線下發出色彩斑斕的光。

And we do not need to spend any money to buy light boxes and do not need to worry about the side effects of ultraviolet light 難怪同修修行之后,心情越來越開朗,而且不用花錢買光線盒,也不用擔心有紫外線的副作用。

Others have created skin - tissue cultures that glow colourfully under ultraviolet light by splicing in a gene from a species of coral 另一些人通過剪接一種珊瑚的基因,發明了能在紫外光下發出彩色光的皮膚組織。

Eprom : erasable programmable read only memory : switch pattern in circuit can be erased by exposure to ultraviolet light 可擦可編程只讀存儲器:可擦可編程只讀存儲器:暴露于紫外線光就可以擦除電路控制方式。

Cholecalciferol is produced by irradiation of 7 - dehydrocholesterol with ultraviolet light either from the sun or from an artificial source 膽鈣化醇是7 脫氫膽固醇經日光或人工來源的紫外線照射而產生的。

However , the most important ones are b1 , b2 , g1 and g2 , distinguished by their fluorescenct colour under ultraviolet light 最主要分為b1 、 b2 、 g1及g2四類。它們在紫外光下各具易辨的熒光色。

Ionizing an atom of hydrogen takes an energy of 13 . 6 electron volts , an amount delivered by a photon of ultraviolet light 游離氫原子需要13 . 6電子伏特,相當于一個紫外光光子所能提供的能量。

Red , blue and green fibres ( randomly embedded in the paper ) visible under ultraviolet light . multitone and highlight watermarks 在紫外光下可看到紅、藍、綠三色纖維不規則地分布在鈔票上。
