构效关系分析发现，在三唑环1位芳基的对位引入F、Cl、Br吸电子基团以及3位引入磺酰基和甲硫基，对抗炎活性有重要的意义；在三唑环5位芳基的对位引入氨磺酰基，对抗炎活性有较大影响。

And it is noted that the velocity field in a hydrocyclone is divided to two areas, i.e. the outer para-free-vortex and the inner para-forced vortex. The boundary surface of the velocity field is the maximum tangent velocity track surface, which is a cylinder when the hydrocyclones structure is reasonable.

分析研究结果表明，旋流器的切向速度场由外部准自由涡和内部准强制涡两个区域构成，其分界面为最大切向速度vtmax的轨迹面，结构设计合理时，此轨迹面为一圆柱面。

The para-/ortho- product isomer ratio is 6.2 for the nitration of chlorobenzene at 18℃ for 8h with n/n(NH4NO3)=5. The para-/ortho- product isomer ratio is 14.0 for the nitration of bromobenzene at 0℃ for 8h with n/n(NH4NO3)=5. The pars-product, p-nitrobromobenzene, from the nitration of bromobenzene in [HSO4] under 0℃ precipitates with 98% purity, which facilitates the separation of the pure isomert.

其中氯苯在18℃下反应8h，三氟乙酸酐/硝酸铵为4时产物的对邻比达到6.2，而溴苯在0℃下反应8h，TFAA/硝酸铵为5时产物的对邻比可达到14.0，并且生成的对硝基溴苯可以从反应液中析出，得到对硝基溴苯含量为98%的产物。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a&和4a&也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。
