查询词典 quenching

It demonstrated that the molecular size matching and the sterically arrangement of groups of studied compounds with nucleoside phosphates are very important for the interaction of them. And the quenching ability depends on the interaction of these species strongly. Evidently, this phenomenon can be used as a method for the molecular recognition of nucleoside phosphate by the changing of fluorescence intensity of these compounds.

实验结果表明，分子尺寸的匹配和化合物中基团的空间合理排布是化合物和核苷磷酸盐间能发生相互作用的重要根据，而猝灭则强烈地依赖于这类物种间的相互作用，因此可利用化合物荧光强度的改变来识别各种不同的核苷磷酸盐。

Crassipes and P. stratiotes, while in A. philoxeroides both qE and state transition dependent quenching played importment role in photoprotection. E. crassipes had the best adaptability to changing light environment, and P. stratiotes took the second place among three plants.

强光下水葫芦和大薸非光化学淬灭的主要组分是能态淬灭，而空心莲子草的主要组分是qE和状态转换淬灭。3种入侵植物中水葫芦的适应能力最强，大薸次之，空心莲子草最低。

The problem of fluorescence quenching of the studied compounds by ctDNA was also been investigated. The results indicate that the compound with tripedal has a stronger interaction with ctDNA than that of other compounds for which one or two pedals were contained.

工作还研究了ctDNA对该类化合物荧光的猝灭问题，提出具有三足多胺结构的该类化合物比其他两种化合物-双足及单足多胺化合物有着更强的与DNA相互作用的能力。

And the chelation-enhanced fluorescence effect of tripodal naphthylethylamide derivative appeared when it was complexed with transition metal ions such as Cu〓 which have quenching potential.

其原因在于络合的过渡金属离子抑制了化合物的PET和化合物的三足结构又屏蔽了过渡金属离子对荧光体的直接猝灭作用。

However, in electric field computation, the BEM has not much unfould and most of them are limited in the conventional BEM. In the flow field computation, although some achievements have been gained in solving the constant and uncompressible fluid flow by using BEM, but to the inconstant, compressible, nonlinear, transonic flow, such as the flow in the arc quenching chamber in SF6 high voltage circuit breaker, no any report has been published up to now for the reason that the basic solution of this kind of flow has not been found.

目前，在电场计算领域所开展的工作相对较少，而且仅限于传统边界元方法的应用；在计算流体力学领域，近年来虽然一些学者应用边界元法，在解决定常、不可压缩等问题进行了相当深入的研究，获得了若干研究成果，但是对于像SF_6高压断路器灭弧室中存在的非定常、可压缩、非线性、跨音速、具有复杂而且变边界的气流场由于至今尚未找到基本解，而未见研究工作的报道。

The natural vanadiferous rutile was modified by heating, quenching and electron irradiation, and the different photoactivities of samples under different treatments were studied.

天然含钒金红石样品经过1273K加热、淬火和高能电子辐照处理后性质发生不同程度的变化。

Based on a brief review of semiconductor photocatalytic mechanism and researches in the past 30 years on TiO2 heterogeneous photocatalysis, this paper emphasizes that the natural vanadiferous rutile and its modified products, which have not been investigated by either Chinese or foreign research groups, degrade halogenated organic contaminants. By means of grinding, heating in situ, heating, quenching and electron irradiation, the natural rutile could be modified.

在简述半导体光催化理论及TiO2多相光催化作用近30年研究现状的基础上，重点对国内外一直处於空白状态的天然含钒金红石光催化性能进行研究。
