chromophotograph

It also has stronger hydrogen bond which can result in partly physical crosslinkage in polymers , which can fasten orienting of chromophore . all these benefit to obtain high nlo coefficient . in chapter one , some basic conceptions about lc and the advance in lcpu are described , especially the synthesis methods on lcpu and the influence factors of lcpu formation liquid crystalline phase 聚氨酯液晶是分子排列具有一定取向的聚合物材料,可為非線性光學聚氨酯提供一種較好的非對稱取向的介質環境,聚氨酯中還存在較強的氫鍵作用,使得聚合物材料有部分物理交聯,能固定發色團的取向,這些因素有利于獲得較大的非線性光學效應。

Ag + and fe2 + caused the fluorescence of trp residues in g6pd quenched ; mg2 + and edta made fluorescence intensity of g6pd increased , this indicates that they caused trp residues wrapped and came to the inner core and located in the hydrophobic area ; while zn2 + or mn2 + made fluorescence intensity of g6pd decreased , this indicates that they made the conformation of g6pd relaxed and chromophores exposed to polarity environments . in native condition and in the far circular dichroic ( cd ) region , g6pd exhibited two characteristic negative band centered at 208nm and 222nm respectively , thus it is estimated to contain about 41 . 2 % a - helix , 20 . 6 % - pleated sheet and 38 . 2 % random coil and turn Ag ~ +和fe ~ ( 2 + )引起色氨酸( trp )殘基的熒光淬滅; mg ~ ( 2 + )和edta均使g6pd的熒光強度增強,說明它們使trp殘基重新包裹在分子內部而處于疏水的微環境中; zn ~ ( 2 + )和mn ~ ( 2 + )均使g6pd的熒光強度變小,說明它們使酶分子構象變得疏松,原來處在分子內部的發色團暴露在極性環境中。

This course concentrates on the chemical characteristics of dyes and pigments , with emphasis on attempts to interpret their colouring and fastness properties in terms of the essential structural features of colourant molecules . some important intermediates and their uses in the synthesis of major chromophores are also indicated 本課程主要針對染顏料化學結構與化學性質對其染色性、色光以及牢度的關聯予以探討,當然也探討一些重要染顏料以及中間體的制備。

Six quaternary ammonium tetraphenyl borates salt photobase generators were synthesized with the use of p - methoxy phenacylmethylene or 2 - naphthoymethylene as chromophore , and triethylene diamine , pyridine or 3 - methyl pyridine as tertiary amine 摘要以對甲氧基苯乙酮、萘乙酮生色團為母體、雜環叔胺三亞乙基二胺,吡啶, 3 -甲基吡啶和四苯硼鹽為原料,合成了6種四苯硼季銨鹽光產堿劑。

Beer - lambert law , more commonly known as beer ' s law , states that the optical absorbance of a chromophore in a transparent solvent varies linearly with both the sample cell pathlength and the chromophore concentration 比爾-朗伯定律,更多的被稱為比爾定律,是指在透明溶劑中發色團的光束吸收度隨著樣品電池路徑以及發色團濃度的變化而呈線性變化。

Some metal ions made g6pd conformation changed and caused the micro - environment of chromophores varied , which made the ultraviolet absorbance peak of g6pd in 276nm wider and flatter 部分金屬離子使g6pd的構象發生改變,發色團所處的微環境隨之發生變化,使紫外吸收峰變寬變平。

Most often , lignin fragments form chromophores that impart a yellow - brown color to the effluent ; making colored paper also causes residual dyestuffs to infuse the effluent with colors 盡管廢水其馀參數均皆合格,廢水之顏色常令人有不潔凈之感,也因此導致環保抗爭問題。

In practice , beer ' s law is accurate enough for a range of chromophores , solvents and concentrations , and is a widely used relationship in quantitative spectroscopy 事實上,比爾定律對一系列發色團、溶劑和濃縮物品而言都是非常精確的定律,在定量光譜學中被廣泛運用。

Reductive treatments were effective against ligneous chromophores , but this was often not so for chemical dyestuffs 還原劑處理對木質素色質有去除效果但對廢水之染料常無效。
