The free phosphonic groups shielded most of the Lewis-acid sites on the surface of zirconia and imparted negative charges on the surface at high pH, resulting in excellent resolution for phenols and a great improvement for the separation of benzoic acids.

在该固定相上，酸性化合物的色谱性能得到明显改善，硝基酚、苯二酚等在氧化锆上通常难以洗脱的酚类化合物，均得到了高效分离。

These reactions increase the probability of incomplete combustion and are more likely to release uncombusted and photochemically active hydrocarbon compounds into the atmosphere.

这些反应增大了不完全燃烧的可能，并且更容易释放未燃烧的碳氢化合物，而这些化合物又对光化学反应很活跃。

Tetrahydroisowuinolin derivatives and phthalide derivatives were designed and synthesized on the basis of a PDE4 inhibitor pharmacophore model set up through computer simulation. Some tetrahydroisowuinolin derivatives synthesized were evaluated on their activity against PDE4 for study on the structure-activity relationship.(7-cyclopentyloxy)-6-methoxy-3,4-dihydroisoquinolin-2(1H)-yl(4-hydroxy-3-methoxyphenyl)methanone (155) and Methyl 7--6-methoxy-2-(4-methoxy- benzoyl)-1-phenyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylate (170) showed good activity against PDE4, which were chosen as the lead compounds to design and synthesize another analogs in order to develop selective PDE4 inhibitors with better activity.

The biological activities of the new heterocycles synthesized were researched, and the results showed that some of them exhibited good fungicidal activities. The best one was compound 3f which exhibited 100% inhibition action against pyricularia oryzae and physalospora piricola in dosage of 5×10^(-5).

并探讨了所合成的新型杂环化合物的生物活性，结果表明部分化合物表现出良好的抑菌活性，其中3f的活性最好，在品质分数为5×10^(-5)浓度时，对稻瘟菌和苹果轮纹菌的抑制率均达到100%。

The crystal structure of the compound consists of norfloxacin cations and picric acid anions.
