中文摘要：
激光诱导发光的方法是测量燃烧过程中颗粒浓度的有效方法。这种方法最吸引人的特点是粒子经过激光加热后，产生的辐射远高于周围火焰的辐射，这样可以有效地剔除火焰自身的辐射对测量的影响。该文介绍了激光诱导发光法测量碳黑粒子浓度的模型，对激光加热过程中碳黑的粒径和温度的变化进行了计算，并与经典结果进行了对比，验证了计算的有效性，文中最后考察了几个重要因素：初始温度（即火焰温度）、初始粒径、激光器波长和激光器强度对碳黑加热过程的影响。该文的数值模拟计算为进一步测量研究奠定基础。
英文摘要：
The technique based on laser induced incandescence is an effective method of the particle concentration measurement in the combustion process. The most attractive advantage of this method is that the effect of the flame radiation can be eliminated because radiation from laser-heated soot is much stronger than the ambient flame radiation. In this paper the model of the soot particle concentration measurement is presented. The variations of the particle size and temperature during heating process are calculated and compared with the classical results. After proving the availability of the calculation, the effect of the vital factors on the heating process of soot particles, such as initial temperature （flame temperature）, initial particle size, laser wavelength and intensity are discussed, The results of the simulation calculation will be useful for the further measurement research.
