Using a Molybdenum target mounted at the axis in our φ800 mm low density shock tube as a phototn detector to monitor the flux density of the precursor vaccum ultraviolet photon ahead of the shock waves, some useful resulta are obtaind. (1) The photon flux density as a function of the distance ahead of the shock, i.e. the radiation profile, is determined experimentally. A simple model is proposed, in which the illumination by the radiation of high temperature shock waves of finite size and absorption by the gas ahead of the shock waves are considered. The agreement between the experimental results and theoretical estimation based on the simple model are resona-ble. (2) The mechanism and the exitation kinetics of the vaccum ultraviolet radiation in argon are investigated. The intensity versus frozen temperature is an Arrhenius plot with an activation energy 11.4 ev which is just the first exitation state of argon. And the intensity is proportional to the square of the initial pressure. The mechanism which fulfils these experimental facts is the nonequilitorium resonance radiation exited by argon-argon collision. The cross-section coefficient is dertermined in the present work 8*=1.2×10-17 cm2 ev-1. (3) The vaccum ultraviolet radiation produced by strong shock in air is due to the electronic transition b1∑→X1∑ of nitrogen molecule, the measured photon flux density Versus frozen temperature is an Arrhenius plot with a apparent activation energy 8.1 ev which contradict to the value 12.9 ev obtained by molecular spectra. The photon flux density is proportional to the initial pressure. In order to fit these experimental facts, a simple modle of the radiative shock front structure is proposed, in which effective thickness of the rediative layer is related to the dissociation relaxation of oxygen. The radiation is nonequiliibrium and the controll process is the exitation X1∑→b'1∑ by molecule-molecule collision, then the activation energy 12.1 ev is obtained and the exitation cross-section of molecular nitrogen is determined in the present work Q*=2×10-16 cm2

The fluorescent contribution to the total spectral radiance factor, which results from fluorescent colorant excited by the ultraviolet or the short-wavelength visible light, is not considered in Kubelka-Munk theory. The fluorescent power emerging from the colorant can only be measured by the optical instruments, but not be calculated quantitatively by theory. For this reason, it is impossible to make color matching in computer. In this paper, a model of transforming the excitation spectrum into the fluorescent...

The fluorescent contribution to the total spectral radiance factor, which results from fluorescent colorant excited by the ultraviolet or the short-wavelength visible light, is not considered in Kubelka-Munk theory. The fluorescent power emerging from the colorant can only be measured by the optical instruments, but not be calculated quantitatively by theory. For this reason, it is impossible to make color matching in computer. In this paper, a model of transforming the excitation spectrum into the fluorescent spectrum is developed by using the concept of the generalized quantum efficiency based on Kubelka-Munk theory. A formula for calculating the total spectral reflected radiance factor of fluorescent colorants is derived, and some important conclusions are also obtained.

在库贝尔卡-芒克理论中,没有考虑紫外光或短波可见光激发荧光色料产生荧光对总光谱反射辐亮度因子的贡献。色料激发辐射的荧光只能用光学仪器来测量,无法进行理论上的定量计算。因此无法进行荧光色料的计算机配色。本文在库贝尔卡-芒克理论基础上,运用广义量子效率概念,导出了荧光色料的总光谱反射辐亮度因子公式,得到了一些重要结论。
