本研究涉及辐射传热;其目的是 开发一种技术，这将是第一次， 同时测定折射率、尺寸和 光散射法测定火焰中碳烟颗粒浓度 测量. 煤烟颗粒的折射率的知识是 用于确定火焰的辐射热传递， 评估火焰中碳的形成和增长的机制， 激光诊断 火焰下这些指数的测定 条件是一个可怕的问题，可靠的价值观还没有 确立了习 在拟议的研究中，一种用于推断 将开发从现场光学测量得到的折射率。

This investigation concerns radiative heat transfer; its purpose is to develop a technique which will allow, for the first time, a simultaneous determination of the refractive index, size and concentration of soot particles in flames from light scattering measurements. Knowledge of the refractive indices of soot particles is required for determining radiative heat transfer from flames and for assessing the mechanism of carbon formation and growth in flames using laser diagnostics. Determination of these indices under flame conditions is a formidable problem and reliable values have yet to be established. In the proposed study, a technique for inferring refractive indices from in-situ optical measurements will be developed.
