氧气

One Nitroso-bacteria named N1(GenBank registered number: EU647556) was isolated from the SBBR one-step completely nitrogen removal process, and was identified as Nitrosomonas sp. The characteristics of N1 were studied. Results showed that the optimal temperature and pH of N1 were 8.0 and 30℃respectively and sufficient dissolved oxygen was demanded.

N1(NCBI数据库中注册号为EU647556)，该菌株对氧气需求量存在较严格要求，pH及温度对其氨氧化活性具有明显的影响，最适条件分别为pH8.0和30℃，在氨氮浓度80～800mg/L较宽的底物浓度范围内具有活性，当氨氮浓度高达800mg/L时，其氨氧化活性没有受到明显的抑制。

Hill reaction The reaction, first demonstrated by Robert Hill in 1937, by which isolated illuminated chloroplasts bring about the reduction of certain nonphysiological electron acceptor with accompanying evolution of oxygen.

希尔反应：是1937年由罗伯特希尔首先证明的一种反应。离体叶绿体在光下可使某些非生理性的电子受体还原，并伴随着氧气的释放。

The traditional transformer online monitoring system generally adopts oxygen carrier gas, chromatographic column. And the equipment is not simple with many shortages such as periodic calibration of chromatography column and sensor, low reliability of equipments and overelaborate detection procedure of gas composition.

由于变压器传统的在线监测系统一般采用色谱柱，需要消耗氧气和载气，而且色谱柱和传感器需定期标定，装置可靠性不高，检测气体成分过程繁琐，因此第6章根据比尔-朗伯特(Beer-Lambert)定律，按照光纤气体差分吸收的原理，设计了一套基于光纤气体传感器的变压器在线监测系统。

And we have demonstrated through differential scanning calorimetry, thermogravimetry,XPS and SEM analysis that the formation of highly reflective and conductive silver layers on polyimide film is a result of the silver-catalyzed and oxygen-assisted decomposition of the polymer overlayer and the self-accelerated aggregation of silver clusters on the film surface.

并通过差示扫描量热、热失重、XPS和SEM分析证明了聚酰亚胺表面高反射高导电银层的形成是在银催化下、氧气辅助的表层聚合物降解和表层银颗粒自加速聚集共同作用的结果。
