摘要(Abstract):

本文探讨了金属卤化物灯中汞蒸汽压的各种测定方法;并用Bartels方法测量了NavarNEC10000K70W金卤灯等离子体温度轮廓,用Abel转换测定Hg577nm和579nm谱线的发射系数,在此基础上,通过比较两次诊断的灯管中心温度进而确定此金卤灯额定功率稳态运行过程中的Hg蒸汽压。
The methods used to determining mercury vapor pressure in discharge lamps are introduced.Bartels method is used to measure the temperature profile of the NavarNEC 10000K 70W metal halide lamp.The emission coefficients of the two mercury lines in 577nm and 579nm are calculated by Abel Inversion.By comparing the temperature determined by these two methods,the mercury vapor pressure can be deduced.
