二苯胺

Silver nanowires with clean surface were synthesized via the redox reaction between Sodium diphenylamine sulfonate and AgNO in the absence of surfactant, seed, and nanoporous membrane and at room temperature for the first time.

首次在室温，和不用表面活性剂、无机硬模板、晶种的条件下，通过二苯胺磺酸钠和硝酸银的氧化还原反应，制备了表面洁净的银纳米线。

Diphenylamine has been found to be an excellent coupling agent for the identification of aromatic amines.

本文推荐了二苯胺作为鉴芳胺化合物的偶合剂，其优于β-萘酚之点在于在酸性介质中即可偶合，试剂稳定便于貯藏，尚可进一步进行酸硷颜色变化试验及氧化还原颜色变化试验。

It is found that the fluorescence intensity is increased with the elevation of temperature when the quencher diphenylamine is added to PU-DFY, which is an inverse phenomenon against the general fluorescent materials.

研究还发现，加入二苯胺猝灭剂的PU-DFY，荧光强度随温度的升高而增强，与一般荧光物质荧光强度的温度特性相反。关键词：聚氨酯-分散荧光黄；高分子荧光染料；水分散体；荧光

Diphenylamine method) and 2600mgkg-1NO3-. Based upon the results from nitrogen nutritional diagnosis.

确定了春小麦用两种方法进行氮素诊断的临界值分别为2.55（NO3-N色阶，二苯胺法）和2600mgkg-1（NO3-，反射仪法）。

Diphenylamine contents in single base propellants were determined by means of a single-sweep-square-wave polarography after the treatment of nitrosation of DPA.

将单基发射药亚硝化后用单扫描方波极谱法测定溶液中的二苯胺含量，用丙酮溶解单基发射药试样，使用组成与待测样品相同的单基标准样品作工作曲线。

Two quick test methods (diphenylamine method and nitrate test strip) for diagnosising nitrogen nutritional status in spring wheat were studled in field expriment.

通过田间试验研究了两种快速诊断方法，二苯胺法和反射仪法在春小麦氮营养诊断中的应用。

Methods The learning and memory capability of mice was investigated by Y-water maze test and step-down test. The contents of protein, DNA and RNA were investigated by Lowry methods, the diphenylamine reagent method and Oricinol reagent method.

用Y-型水迷宫法、跳台法测定小鼠的学习记忆能力，Lowry法测定小鼠脑内蛋白质，二苯胺试剂显色法测定DNA，Oricinol试剂显色法测定RNA的含量。

According to Griess reaction, diazonium-salts formed from aromatic amines such as sulfonamides etc., react with NaNO_2 in acid medium and may be coupled with α-naphthylamine or diphenylamine to produce red colored compounds.

一按Griess反应芳香族胺类的重氮化鹽，如对氨基苯磺醯胺类药物等，在酸性溶液中皆能与α-萘胺或二苯胺分别偶合成偶氮色素而显紅色，过多之亞硝酸可与氮色素再作用使紅色消失而呈棕黄色。

The complexation of SCnA also results in a bathochromic shift and a decrease in optic intensity of the absorption spectrum of DS.

在水溶液中磺化杯芳烃可与二苯胺重氮盐形成包结物，导致DS的化学位移向高场移动，同时使其吸收光谱红移，强度下降。
