The attenuation coefficient ratio (alphalambda/alpha(o.546)) for artificial fogs has been measured at 345 micro, coefficient ratios at 0.436 micro, 1.01 micro, 3.5 micro, 10 micro, and 13.5 micro were also measured so that a comparison between artificial fogs and natural fogs could be made. By comparing our results with others on natural fogs and with the theoretical work of others in the visible and near ir, we have concluded that our artificial fogs closely resemble natural fogs. We conclude, therefore, that alpha(O.345)/alpha(o.546) is representative of real fogs. Artificial fogs are generated and allowed to dissipate during which time attenuation of light at several wavelengths is recorded. The green line of the mercury arc at 0.546 micro was used as the standard of comparison. For radiation at 345 micro,(alpha345/alphaO.546) = 0.014 +/- 0.009 during the generation time of the fog and 0.021 +/- 0.006 during the time the fog is allowed to dissipate.
已测量了人造雾在345微米处的衰减系数比(αλ/α(0.546)),还测量了在0.436微米、1.01微米、3.5微米、10微米和13.5微米处的系数比,以便能够对人造雾和自然雾进行比较。通过将我们的结果与其他人关于自然雾的结果以及其他人在可见光和近红外波段的理论工作进行比较,我们得出结论,我们的人造雾与自然雾非常相似。因此,我们得出结论,α(0.345)/α(0.546)代表真实的雾。产生人造雾并使其消散,在此期间记录几个波长处光的衰减。汞弧在0.546微米处的绿线用作比较标准。对于345微米处的辐射,在雾的产生期间(α345/α0.546)= 0.014 ± 0.009,在雾消散期间为0.021 ± 0.006。
