| 摘 要： | 大气气溶胶的虚折射率是大气气溶胶的一个重要物理参数,它表示气溶胶对光辐射的吸收特性。大气气溶胶中的元素碳是重要的吸光物质。因此,对大气气溶胶中元素碳的测量及与大气气溶胶虚折射率测量的相关性研究具有重要意义。 本文提供了利用240C元素分析仪测量大气气溶胶中元素碳含量的方法,并对大气气溶胶元素碳含量与大气气溶胶虚折射率的测量结果作了相关性分析。结果表明,两者之间存在明显的正相关。

| Abstract: | The imaginary refractive index of atmospheric aerosols is an important physical parameter, which characterizes the absorbing property of the atmospheric aerosol. The elemental carbon is the essential absorbing material of atmospheric aerosols. Therefore, it is important to measure the content of the elemental carbon in atmospheric aerosols and to correlate it with the imaginary refractive index of atmospheric aerosols. In this paper, we present a method to measure the elemental carbon in atmospheric aerosols with the "Model 240C Elemental Anlyzer" and then make the correlation analysis with the imaginary refractive index of atmospheric aerosols. The result shows apparently positive correlation between them. |
