Research points out that the three key factors , which determine the nox emissions , are maximum peak temperature , rich oxygen concentration and the duration in which combustion products stay at high temperature zone 船舶柴油机的氮氧化物主要是山于大气中的氮在柴油机燃烧过程中被氧化而成。研究表明高温、富氧以及燃烧产物在高温区的停留时间是决定氮氧化物排放量的三个决定因素。
Research point out that the three key factors , which determine the nox emission , are maximum peak temperature rich oxygen concentration and the duration in which combustion products stay at high temperature , thereby in the section of diesel of diesel emission control measures , for lowing effectively the diesel engine nox exhaust , in the section of diesel emission control measures , respectively narrate the methods to reduce the crucial discharges of diesel engine about nox emission from engine inside disposal and engine outside purge 柴油机的氮氧化物主要是在气缸内燃烧的高温条件下空气中的氮与氧反应而生成。研究表明氮氧化物排放量取决于高温、富氧以及燃烧产物在高温区的停留时间三个因素。为有效降低柴油机氮氧化物排放,本文从机内处理和机外净化两个方面概述了不同的控制技术。
The fluorescence spectrum ( fls ) of lra excited at 280nm and 295nm showed a maximum peak at 338nm . the characteristic peak of tyr did not exist , and it showed that the fluorescence energy of tyr was transformed to trp and strength the fluorescence of trp . when lra was excited at 295nm , the fls showed a maximum peak at 338nm , the max of fluorescence emission spectrum blue - shifted more than 10nm compared with the max of free tyr ( 348nm ) Lra的荧光光谱研究表明在激发光波长为280nm时,其最大荧光发射峰在338nm处,荧光光谱未见有酪氨酸( tyr )残基的发射峰,表明tyr残基的荧光基本上通过能量转移到trp上,使荧光强度增强,在激发光谱为295nm时,其最大荧光发射峰338nm ,比游离trp的最大荧光发射峰( 348lun )蓝移了近10nln ,说明trp周围的极性较弱,处于疏水的微环境。
