AbstractCTS-9905581Wooldridge/University of MichiganAn argon-ion-pumped ring-dye laser system is acquired and is used to obtain in situ quantitative gas-phase species concentration, temperature, particle diameter, number density, and volume fraction measurements in particle formation and growth studies. Two diagnostic approaches are used: in one, the narrow line, tunable emission features of the ring-dye laser are used to obtain species profiles in particle-growth studies under controlled experimental conditions; in the other, the argon-ion laser is used as a high-power, monochromatic emission source for particle scattering studies.

摘要：本文获得了一种氩离子泵浦环形染料激光系统，用于颗粒形成和生长研究中原位定量气相物质浓度、温度、颗粒直径、数量密度和体积分数的测量。采用了两种诊断方法：一种是在受控实验条件下，利用环形染料激光的窄线、可调谐发射特征来获得粒子生长研究中的物种概况；另一方面，氩离子激光器作为高功率单色发射源用于粒子散射研究。
