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 (Malm et al.,1994) and Stelson (Stelson and Seinfeld, 1981) were used to study the mass closure of sampled aerosols.

本文通过在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，但总的来说两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。

The great potentials for exploration of litho-stratigraphic reservoirs do not appear until new methods and technologies have been applied and in-depth understandings have been gained. In recent two or three years, big discoveries have been made in Jilin oilfield, in which 80 percent of reserves are found in some areas of thin sand-shale interbedding of its delta front. There still exist petroleum potentials amounting to 6×10^8 t for exploration in this area, especially in southern Songliao basin where the litho-stratigraphic traps will be more important domains and deserve extra attention. Hence, geologically speaking, this study on the hydrocarbon accumulation of litho-stratigraphic reservoirs in Songliao basin is of vital significance to exploration of the southern Songliao basin.

但通过新方法、新技术的应用和地质认识的不断深入，岩性－地层油气藏展现出了较大的勘探潜力，吉林油田近2-3年来的大发现和新增储量的80％是在有一定面积的三角洲前缘薄互层中获得的，在这个领域中仍有6×10^8t的石油资源有待勘探，特别是松辽盆地南部地层－岩性圈闭是未来油气勘探的重要领域，具有进一步解剖研究和勘探价值，因此，对松辽盆地岩性－地层油气藏成藏规律进行研究，对于松辽盆地南部勘探有着十分重要的意义。
