测定了三种不同车辆柴油机尾气颗粒硫K边的软x射线吸收光谱。x射线光谱是用同步辐射光束线测量的。光谱采用表面灵敏全电子产率法和体灵敏x射线荧光产率法测定。一辆车将S2−集中在排放颗粒表面；其余的不集中S2−。这种化学状态分析方法适用于柴油排放等过程分析。
Soft X-ray absorption spectra of sulfur K edge were measured for diesel exhaust particles from three different vehicles. The X-ray spectra were measured using a synchrotron radiation beamline. The spectra were measured by surface sensitive total electron yield method and bulk sensitive X-ray fluorescence yield method. One vehicle concentrated the S2−on the surface of the emission particles; the others did not concentrate S2−. This type of chemical state analysis method is useful for the process analysis such as diesel emissions.
