The changes in phase structure and Curie temperature of the Sm2Fe17 compound after nitrogen absorption were studied by using X-ray diffraction, differential thermal/thermo-gravimetric analyzer and magnetic measurement. The results of X-ray diffraction showed that the diffraction peaks of the Sm2Fe17 compound shifted toward lower angle after nitrogen absorption, and the characteristic peaks of α-Fe were observed. This showed that the unit cell of Sm2Fe17 expanded, the compound was decomposed to a certain extent and the characteristic peaks of α-Fe appeared.

通过X-射线衍射、差热－热重联用仪以及磁测量等手段，研究了Sm2Fe17化合物吸氮后的相结构及居里温度的变化行为。X-射线衍射表明，吸氮后Sm2Fe17化合物的衍射峰向小角度方向偏移，并且出现了α-Fe的衍射峰，这说明吸氮后化合物的晶胞有所膨胀，并且化合物有一定的分解，产生了α-Fe。

Based on the data of aerosol chemical compositions obtained at WMO GAW(World Meteorological Organization Global Atmospheric Watch) station in eastern China——Lin'an regional background air pollution monitoring station,two methods(referred as Malm method and Stelson method) that were described by Malm and Stelson were used to study the mass closure of sampled aerosols.The inter-comparison of reconstructed aerosol masses with the gravimetric masses showed good agreements,although the tw...

通过在WMO GAW区域大气本底污染监测站——临安大气本底污染监测站采集的气溶胶样品的化学成分的分析结果，分别用Malm(1994)和Stelson(1981)提出的方法(分别记为Malm方法和Stelson方法)重建气溶胶质量浓度，并与称重获得的质量浓度进行对比，发现虽然Stelson方法和Malm方法所考虑的物质组成及所使用的化学成分个数并不相同，其计算结果略有差异，但总的来说2种方法都能较好的反映绝大部分的气溶胶质量，在实际应用中可以根据所分析的化学成分数据情况和研究的目的采用不同的质量重建方法。
