With the reduction of SOM content and the elevation of contamination concentration, the difference between PHE and PYE decreases gradually, while B［a］PYE exhibits a significant difference from them. This could be attributed to the high lipophilicity and large molecular size of B［a］PYE, which make the molecule of B［a］PYE to be more easier to be held in the nanopores of clay and the dense region of SOM.

不同多环芳烃SPMD辅助解吸率差别很大，随着土壤有机质含量的降低，以及污染物浓度的提高，菲和芘的解吸差异逐渐缩小，而苯并［a］芘与上述2种多环芳烃的差异很大，主要是由于苯并［a］芘具有高度亲脂性，并且分子较大，造成其容易滞留在粘土的微孔及有机质的致密结构中。

Not him, nor him, nor him, is that it only it can steal my heart, it not only stole my heart, my soul also is also bordered by a beautiful silver edges, so that sailed the seven seas of the Love began to smolder, since it is has not gone do?

不是他、也不是他、更不是他，是它，只有它可以偷走我的芳心，它不但偷走了我的芳心，还把我的灵魂也镶上了美丽的银边，让那个曾经沧海的爱情又开始蠢蠢欲动，既然是曾经，不是已经过去了吗？

The analysis of SAR reveals that the activities of target compounds are closely associated with the electron-withdrawing substituents at the para position of 1-aryl-1, 2, 4 -triazoles as well as with the substituents such as sulfonyl and methylthio groups at the 3 position of 1, 2, 4 -triazoles; And the introduction of sulfamoyl moiety at the para position of 5-aryl-1,2,4-triazoles also has significant influence on the anti-inflammatory activity of these compounds.
