This method can reduce sludge production radically and virtually. The effectiveness of eight metabolic uncouplers in reducing sludge production from activated sludge process were compared to screen effective, cheap and non-toxic available uncoupling chemicals and determined the long-term uncoupler effects of 3, 3', 4', 5-tetrachlorosalicylanilide in activated sludge batch cultures.

Second, the solthe solthe sol-gel solution did not contain alcohol, instead, poly methyl methacrylate, aniline and phosphate salt(calcium phosphate dibasic, manganese phosphate or zinc phosphate) were added.

第二部分是在未加入酒精的状况下，将有机高分子聚甲基丙烯酸甲酯(poly methyl methacrylate， PMMA)加入含有磷酸盐(磷酸氢钙、磷酸锰或磷酸锌)的溶胶中，并利用苯胺的催化，得到奈米级的有机-无机复合皮膜。

Acting as an antenna molecule in the supramolecular system, Mg(superscript 2+)-HA remarkably enhances the photoinduced electron transfer efficiency between C60 and an electron donor, N, N-dimethylaniline.

作为超分子体系中的光捕获分子，Mg(上标 2+)-HA能显著地提高C60与N，N-二甲基苯胺的光诱导电子转移反应效率，生成的C60负离子自由基的电子自旋共振光谱信号强度比未加入Mg(上标 2+)-HA时增强了9倍左右。

The aniline HDN was strongly stressed by the presence of quinoline and DHQ and the HDN of quinoline proceeds exclusively via a pathway which involves fully saturated intermediates on the MCM-41-supported nickel phosphides. The HDN activity of nickel phosphide catalyst was dramatically reduced by the presence of H2S and DBT, probably due to the strong adsorption of H_2S and DBT on active sites which inhibited the adsorption of quinoline.

喹啉和DHQ对苯胺的HDN反应有强烈的抑制作用，喹啉在磷化镍催化剂上几乎全部通过完全加氢饱和路径进行反应。H_2S和二苯并噻吩强烈地吸附在磷化镍催化剂活性中心上，阻碍了反应物分子的吸附，从而对喹啉的HDN反应有强烈的抑制作用。

Based on the-references on the thermal imidization of polyand the polymer composition analysis,the thermal imidization mechanism of SMA with aniline was demonstrated to be a two-stage consecutive reaction,in which a second-order reversible ring-opening reaction of SMA to produce poly(styrene-co-N-phenyl-maleamic acid)and a first-order irreversible intrachain ring-closing reaction to form SNPMI were involved.

论文首先参考聚酰胺酸热环化反应，并通过SMA酰亚胺化产物的组成分析，确定了SMA与苯胺的热酰亚胺化反应机理为一个包含由SMA生成苯乙烯—N-苯基马来酰胺酸共聚物的二级可逆开环反应以及由SNPMA生成苯乙烯—N-苯基马来酰亚胺共聚物的一级不可逆分子内闭环反应在内的串联反应过程，其中第二步SNPMA闭环反应为控制步骤。

The epoxy-based second-order NLO polymer was synthesized through the coupling reaction between p -nitrophenyl diazonium salt and an epoxy-based precursor polymer,which was prepared by the polycondensation of diglycidyl ether of bisphenol-A and aniline Bi-component (BPAN-lA-NT/M2OS) thin films were prepared by spin-coating from the solution of BPAN-lA-NT mixed with certain amount of a cross linking agent M2OS.

通过双酚A-二与苯胺的逐步聚合反应合成环氧树脂类先驱聚合物BPAN ，进一步通过先驱聚合物的后重氮偶合反应，制备了侧链带偶氮生色团的二阶非线性光学聚合物BPAN-1A-NT。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
