【Abstract】 The UV-spectral irradiance(200-380nm)of high-pressure xenon lamps(150W)has been measured in various operation conditions.The relationship between the UV-spectral characteristics and the operation parameters of the lamps is investigated and an equation for describing the relationship is found.The result shows that in respect of spectral characteristics the xenon lamp is suitable for being used as a secondary standard source of UV-spectral irradiance.更多还原
