黑碳气溶胶的光散射特性研究

摘要

The paper studies the light scattering properties of black carbon aerosols by using photoelectric detection. Black carbon particles scatter light under the role of laser, which are detected by photodetector. The paper uses the leading edge of scattering light to fit the full Gaussion function of particle's scattering light. Then by the constructed Gaussion function we can analysis the size of Black carbon particles.%利用光电检测法研究黑碳气溶胶粒子的光散射特性,根据粒子的光散射特性来分析它的尺度谱.黑碳气溶胶粒子在激光的作用下产生散射光,利用光电检测器检测黑碳气溶胶粒子发出的散射光.提出了利用散射光信号的前沿部分进行拟合,得到粒子散射光信号的完整高斯分布.
