查询词典 developing dye

It is found from experiment that when pumped by skew light along the fibre's axis, both transverse electric wave and transverse magnetic wave exist in WGM lasing emission simultaneitly. With the increase of refractive index of cladding dye solution, the wavelength spacing between TE and TM waves of which the radial mode number and angular mode number are the same value decreases, and the central lasing wavelength of WGM bluely shifts to short wavelength direction.

实验发现，在抽运光以偏斜光线方式沿光纤的近轴向抽运时，回音壁模式的光纤激光辐射中，既存在光电矢量和光纤径向垂直的横电波，也存在光电矢量和光纤径向平行的横磁波；随增益包层染料溶液折射率的增加，径向模式数和角模式数相同的TE波和TM波之间的波长差单调减小，回音壁模式激光辐射的中心波长向短波方向移动，辐射的波长范围变窄。

研究了溴酚兰、甲基橙、澳甲酚绿、溴甲酚紫、结晶紫等染料对金纳米粒子溶胶共振散射光谱的影响，发现不参与纳米反应的游离分子吸收是产生共振散射峰和共振散射谷的一个重要原因。

In this study, we developed the ammonia sensing material by using MCM-41 impregnated with bromocresol green. MCM-41 is one kind of mesoporous molecular sieves. It can be applied to many fields due to well-defined pore shapes, narrow distribution of pore sizes, large pore volumes, high surface area, excellent thermal, hydrothermal, chemical and mechanical stability. And the bromocresol green dye is commonly used as a pH indicator with colorimetric from pH 3.8 to pH 5.4.

本研究之目的是结合变色染剂及中孔洞分子筛MCM-41进行氨气吸附，研究中所选择之变色染剂溴甲酚绿是一种偏酸性之大分子有机染剂，其变色范围在pH 3.8到pH 5.4；而MCM-41由於其孔洞大小分布范围狭窄、孔洞体积大、高比表面积、具有良好的吸附容积、表面反应性强及易於改质等优点，故期望利用此复合材料，经气体吸附达到氨的移除并同时在吸附饱和前能产生显色效果。

Resonance light scattering spectrum of cadmium- phenanthorline- bromophenol blue system has been studied. The effects of interference substances and optimization of procedure have been investigated. In the presence of Tris-HCl(pH=9.60),Cd2+ reacts with Phen to form the chelate cation, which further reacts with acid dye of BPB to form an ion-associated complex. Then, the complex molecules are accumulated to particles by virtue of hydrophobic forces and other molecular forces. This results in significant enhancement of RLS intensity, and the enhanced intensity of RLS at 638nm is proportional to the concentration of Cd~(2+).

研究了镉-邻菲罗啉-溴酚蓝体系在碱性条件下的共振光散射光谱特征，考察了体系的影响因素和最佳反应条件，研究表明，在pH=9.60的Tris-HCl介质中，镉与邻菲罗啉形成络阳离子，再与酸性染料溴酚蓝形成离子缔合配合物，在疏水力等分子间作用力下，缔合物分子聚集形成缔合微粒，溶液的共振散射光显著增强；在638nm处RLS增强程度与镉浓度成线性关系，线性范围为0-3.20mg/L，检出限为4.50ug/L。
