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。

The inhibitive effect of 1, 2-benzenedicarboxylic acid on the absorption of N, P and K increased with its concentration rising. Low concentration of dibutyl phthalate increased the absorption of N, but decreased the absorption of P and K. Its high concentration restrained the absorption of N, P and K, while the low concentration of diphenylamine could stimulate the absorption of N and K, but restrain the absorption of P.
