生色作用

Auxochromes: An auxochrome is a group which does not absorb significantly in the region 200-800nm, but which affect the spectrum of the chromophore to which it is attached. Examples of auxochromes are

C。 助色团：一些原子和原子团不吸收200-800nm范围内的光，但与生色团结合后，具有能使生色团的吸收峰向长波或短波方向移动的作用，这样的原子或原子团称为助色团。

Three N-pivot lariat ethers with picrylamino group as side arms have been prepared, and the selective coloration of above chromogenic ethers for alkalic metal salts and amines have been studied conveniently by UV-Vis spectra.

设计合成了三个具有分子隙缝的、以苦胺基为侧臂的N-支套索冠醚，利用其生色基和UV-Vis吸收光谱，简便地研究了冠环大小、键连基团对碱金属盐和有机胺选择变色作用的影响。

This may be overcome, as suggested in the present investiga- tion by assuming that the vicinal actions are due to the interactions of various chemical bonds in the molecule with the chromophoric electron.

指出旋光度應由分子中各化學鍵，而不是分子中各原子對於生色團電子的微擾作用來計算，兩者的主要不同點在於是否考慮鍵的多極矩。

The result shows that:(1) the color of turquoise is controlled by Fe~(3+),Cu~(2+), and surface weathering intensity.(2) The structure of turquoise can be described asmicrocrystal-squama texture and spherulitic texture.

结果表明：(1)绿松石颜色除与致色元素Fe~(3+)、Cu~(2+)的含量有关，还与表生风化作用的强度相关，随表生风化作用的增强，颜色变浅，致密程度降低。

The effect of cruciform structure on the two photon absorption action cross-section of fluorescence chromophore was reported. 1,4-Di(9'-ethyl-carbazolyl)-3'-vinylbenzene (R1) is a classic two photon absorption chromophore with D-π-D structure.

报道了十字形结构对荧光生色团的双光子吸收作用横截面积的影响。1，4-二（9'-乙基咔唑基）－3'-乙烯基苯(R1)是经典的具有D-π-D结构的TPA生色团。

The effect of particular saturated bridge during the course of ET and HT in rigid, covalently linked donor-bridge-acceptor dyads has captured the attention of scientists'in this field.

饱和桥在双生色团的给体-桥-受体体系的分子内电子转移和空穴转移过程中的作用一直是此领域的科学家们关注的焦点。

A series of new resonance Rayleigh scattering or resonance light scattering methods for the determination of proteins have been developed.

虽然金属离子及其无机配合物与蛋白质的反应也是蛋白质与小分子相互作用的重要研究内容，且对于了解蛋白质的生物化学性质也有重要作用，但是由于它们不具备生色团，通常认为用吸收光谱和共振瑞利散射光谱法研究有一定困难，迄今报道不多。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
