停留

The calculated results show that the enhancement factor increases with the increase of absorbability of particles.

计算结果表明：增强因子随微粒吸附容量的增大显著增加；微粒距离气液界面越远，微粒吸附能力对气液传质的增强越小；在相同粒径与微粒距离气液界面距离的条件下，增强因子随微粒在气液停留时间的增加而增加，但是当停留时间超过一定值后，随着停留时间的增加，增强因子下降；粒径增大，增强因子减小。

However, because of settling problems in the clarifier, the AS could only be operated at a maximum SRT of 20 days.

由于在澄清器停留的问题，故AS的最大停留时间为20天。

The gasification efficiency increased and the molar fraction of H2 decreased with an increase in the reaction temperature. The decomposition of PVA was more complete at higher temperatures. At 24 MPa, 500℃ and 120 s, the TOC remove rate, the carbon gasification rate and the hydrogen gasification rate were up to 71.46%, 67.97% and 157.24% respectively. A change in the residence time had no significant effect on the molar fraction of gas production but an increase in the residence time could enhance the gasification efficiency of PVA. It was found that the intermediates were mainly alkane, cycloparaffin, aromatic hydrocarbons, and low-molecular weight acids. It was supposed that PVA was degraded into small molecules through breaking of C-C bonds. Parts of the molecules were converted into H2, CO, CH4 and CO2 while some was converted into aromatic hydrocarbons.

过程探索发现：反应温度的升高能提高PVA气化效率，但气体产物中H2的含量随反应温度的升高有所下降；随着反应温度的升高，PVA分解趋于彻底，在压力24MPa、温度500℃、停留时间120s的条件下，TOC去除率、有机碳气化率和氢气化率分别达到71.46%，67.97%和157.24%；停留时间的变化对气体产物含量没有明显的影响，但延长停留时间能提高PVA的气化效率；PVA气化反应中间产物主要为链状烷烃、环烷烃、芳香烃及小分子酸，根据中间产物出现的顺序推测PVA的降解为由C-C键断裂形成小分子物质，这些小分子物质一部分转化为H2，CO，CH4和CO2，一部分形成难降解的芳香族化合物。

The results revealed that the conversion was 92.4% when aniline concentration was 1 mol/L, feeding temperature was 25℃ and residence time was 11 s. With feeding temperature being the main factor, the effect of residence time decreases successively. The diazotization anomalies could be caused at aniline concentration above 1.5 mol/L. The proper feeding temperature which can lead to the highest conversion was 20~30℃.

试验结果表明，在苯胺浓度为1 mol/L，进料温度为25℃，停留时间为11 s时反应转化率达92.4%；苯胺浓度、进料温度、停留时间对反应影响程度各不相同，其中进料温度的影响最大，停留时间次之，苯胺浓度高于1.5mol/L后，对反应影响加剧，导致反应异常；从进料温度对反应的影响试验分析可得，反应转化率最高的进料温度在20~30℃之间。

研究结果表明，甲苯转化率受温度和停留时间的影响较大，尤以温度影响更为明显；主产物选择性受温度和停留时间的影响较小，但停留时间延长，会加剧苯甲醛向苯甲酸转化。

The results show that biomass owns higher NO removal efficiency than pulverized coal. NO removal efficiency of three kinds of fuels increases by different extent through the increase of reburn fuel fraction and the decrease of the excess air ratio. NO removal efficiency of corn straw is the most efficient; rice husk is medium, pulverized bituminous coal is the lowest. Within the certain reburn resident time (650 ms), NO removal efficiency increases quickly with the resident time.

研究表明：生物质脱硝能力明显高于煤粉，提高再然比例及减小过量空气系数，3种燃料的脱硝率有不同程度的提高，其中秸秆脱硝率最高，稻壳中等，煤粉最低；在一定的再燃停留时间内(650 ms)，延长停留时间，脱硝率增加，超过这一停留时间，脱硝率增加缓慢。

The main resultsshowed that the average removal efficiency on Total Nitrogen with planted Phragmites communis and Canna indica were higher than 90% for 1 day and 3 days, but the removal efficiency with planted Scirpus validus and Acorus calamus changed from 51.90% for 1 day to 90.90% for 3 days; The removal efficiency was not significantly different from each other on Total Phosphorus except for Phragmites communis; The combination of Phragmites communis and Canna indica, Typha orientalis and Acorus calamus were good at removing COD; the removal efficiency on NH_4~+-N was the highest with planted Acorus calamus.

结果显示，芦苇和美人蕉组合对总氮的去除率在停留1天和3天时均达到90％以上，而水葱—菖蒲组合变幅较大，从停留1天的51.90％增加到停留3天的90.90％；植物对TP的去除率除了芦苇组合偏低以外，其它植物差别不明显；芦苇—美人蕉组合和香蒲—菖蒲组合对COD去除较好；菖蒲组合对NH_4~+-N去除效果最好。

The sense of texture intertwines with the sense of strokes, giving us not only a powerful impact on our sight, but also strong impacts on our minds. Audience cannot help but stop before his works, pondering at the pictures, at the relationships between shapes of colors, at the aesthetic sensations and imaginations. In this process, we do not only have a better understanding of the images portrayed in the works of art, but feel the excitement from the interaction between his works and our minds.

质感与手感的相互融合，不仅有视觉直观的挑衅性，而且有视觉心理的冲击力，让人不得不停留于画面本身，停留于颜料构造的形式关系，停留于审美感动与审美想像里，领受心物之间互相摩擦、磨合所带来的兴奋与激动，而不仅仅是关于人物形象的认识。

See Webster's Third New international Dictionary, 'integrity.' The pleasure seeker is guilty of shallowness, the approval seeker of artificiality, and the profit seeker of expedience of the worst sort.

参见Webster's Third New international Dictionary对'integrity'的解释寻求愉悦者停留于肤浅；寻求赞许者停留于造作；利益寻求着停留于最低劣的不择手段。

Residence time detection is carried out for wiped film molecular distillation by the impulse response method.

文章采用脉冲示踪法测量了刮膜式分子蒸馏中物料的停留时间分布，研究了示踪剂浓度和电导率强度的关系及刮膜转速、进料速率和物料粘度对停留时间的影响，并与降膜式分子蒸馏停留时间作了比较。
