采用了双离子化室技术,用Xe共振光(波长为160nm)测定了乙基胺类化合物的总的先吸收横截面积。所研究的乙基胺类化合物为一乙胺、二乙胺、三乙胺。 发现了压力对这些样品的总的光吸收横截面积有很敏感的影响。当压力增高时,这些样品的总的光吸收横截面积会出现一个峰值。而且,乙基取代胺中的氢原子愈多,出现总的光吸收横截面积峰值的压力就愈低。
Dual ionization chamber technology was used to measure the total first absorption cross-sectional area of ethylamine compounds using Xe resonance light (wavelength 160 nm). The studied ethylamine compounds are monoethylamine, diethylamine and triethylamine. The pressure was found to have a very sensitive effect on the total light absorption cross-sectional area of these samples. As the pressure increases, the total light absorption cross-sectional area of these samples shows a peak. Moreover, the more hydrogen atoms in the ethyl-substituted amine, the lower the pressure at which the overall peak of light-absorption cross-sectional area appears.
