| 摘 要： | 合肥地区6328埃激光大气衰减测量结果表明,衰减系数σ_(6328)与半径大于0.25微米的大气气溶胶粒子浓度有强烈的线性相关,其相关系数为0.91。但和文献[1]的观测结果不同,直至相对湿度高达75％,衰减系数与相对湿度无明显关系。

Atmospheric extinction measurements of He-Ne laser light |
| |
| Abstract: | Atmospheric extinction of the He-Ne laser has been measured in Hefei district. The results show that the extinction coefficients are strongly correlated with the concentration of aerosol particles with the radius of over 0.25 ×m. The value of linear correlation coefficient has been found to be 0.91. Howerer, as opposed to the results of ref. [1], the atmospheric extinction coefficient data seem to indicate that no obvious correlation exists with relative humidity of up to 75%. Therefore, we think that the aerosol present in Hefei during the measuring period is strongly inhygroscopio. |
