染料

This eliminates the reabsorption loss by ensuring that light is re-emitted at a frequency which the dye molecules cannot then reabsorb.

这种方法通过确保重新放射的光线以染料分子不能重新吸收的频率放射，消除了重吸收带来的损失。

There are exponential functions between the reaction rate constants and electrode potential, NaCl concentration respectively, while the rate constant and initial dye concentration are related with the reciprocal function. Furthermore, the decoloration rate was reduced obviously by high temperature.

脱色反应符合一级动力学，反应速率常数分别与阳极电位、氯化钠浓度存在指数函数关系，与染料初始浓度存在倒数函数关系；高温明显降低脱色降解反应速率。

The thermo-optic coefficients of polymer solution by using Abbé refractometer were demonstrated at natural light and a series of single wavelength lights, respectively.

合成了侧链含染料发色团的聚氨酯－酰亚胺，采用红外光谱、示差量热扫描、热失重分析等手段对合成的PUI进行了表征。

The country has prohibited clothes manufacturers from using resolvable toxic aromatic amine dyes for clothes production.

国家已经禁止服装制造商在生产衣服的时候使用有毒的可溶性芳香胺染料。

While resolvable toxic aromatic amine dyes can make the clothes more brightly-colored, and maintains the color for a longer time.

而有毒的可溶性芳香胺染料则可以使衣服颜色鲜亮，并能使颜色鲜亮维持的更久。

When the 〓I〓 and 〓F〓 states of Er〓 were resonantly pumped by a laser diode at 808nm and a pulsed dye laser at 658nm respectively, we have observed two upconversion bands near 553nm and 413nm.

分别用波长为808和658nm的半导体激光和脉冲染料激光共振激发晶体中Er〓的〓I〓和〓F〓态观测到波长在553和410nm附近的上转换荧光发射。

The excited states of dye DCI monomer are populated by the 532nm laser pulses and the J-aggregate state is near resonantly excited by the tunable dye laser pulses.

这是在复杂染料分子溶液系统在低温下少见的现象，它是与J型聚集体中强烈分子相互作用有关。

Resonant laser ablation is a two-step process, occurring within a pulse of a tunable laser, in which the leading edge of the laser pulse ablates the surface of the solid sample to produce neutral atoms or molecules that are then resonantly ionized by the trailing edge of the same pulse.

共振激光烧蚀技术是指发生在同一激光脉冲时间内的两步过程，它是指用波长可调谐的染料激光取代固定波长输出的激光，并调谐激光输出波长实现所研究原子或分子电子态之间的共振跃迁，激光单次脉冲的前沿对样品进行烧蚀，烧蚀的物质在激光光束内形成粒子气团，同一次激光脉冲的后沿实现对气相原子或分子的共振电离。

Optical properties of Ag nano-particles and Rhodamine B doped PMMA polymer films were investigated.

研究了掺杂银纳米颗粒的染料聚合物薄膜的光学特性。

The degradation process of Rhodamine B, which is refractory to degrade, is investigated with two-dimension-electrode method and three-dimension-electrode method.

采用二维和三维电极法研究了羟基自由基的发生过程及其对公认的难降解的罗丹明B染料废水的降解作用。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
