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.

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。

The contents of mineral elements, like Fe, in LMTCMs were higher than that of nor-LMTCM. The result of analysis of mineral element of 14 LMTCMs by ICP-MS method also showed the content of Fe have something to do with lung meridian tropism effects. The result of the study of platycodon radix approved the laws too. These laws were used to predict if the marine medicines have the lung meridian tropism effects.2. The Compatibility laws of Medicines and their chemical composition in LSP were studied by mining the data of the constituent herbs and their chemical composition. The results showed that the most constituent medicines of lung system prescriptions have lung meridian tropism. Radix glycyrrhizae, herba ephedrae, semen armeniacae amarum, fructus schisandrae Chinese and their compatibility are common in lung system prescriptions. Terpene, alkaloid, steroid, and flavanoid compounds and their compatibility are common in lung system prescriptions.3. The marine phycophyta medicines of LSP were studied by the same method.

对比归肺经中药及肺系方剂主要化学成分构成，萜类、生物碱、甾体类成分可能是归肺经中药及肺系方剂的主要药效成分；结合君臣佐使药的化学成分构成特点及肺系方剂组成中药的归经构成情况，肺系方剂组方设计应该考虑以下几个方面：一、优先考虑归肺经中药，在应用不归肺经中药时要配伍归肺经中药；二、组方时应考虑含萜类、甾体及生物碱类化合物的中药；治疗肺咳病及咳嗽症状时可以考虑含萜类化合物的中药，治疗气喘症状时可以考虑含生物碱类化合物的中药；三、在确定组方中药或化学成分配伍关系时，君药多考虑含生物碱、黄酮类化合物的中药；臣药、佐药可以考虑含萜类及甾体类化合物中药；使药可以考虑含萜类、甾体类及黄酮类化合物的中药。
