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。

在双氧水体系中，以HPA-2为催化剂，考察了反应时间、反应温度以及剂油比对脱硫率的影响，实验结果表明，剂油比对脱硫率的影响最大，剂油比越大脱硫效果越好；反应时间的影响次之，脱硫率随着反应时间的延长而提高，在60min左右脱硫反应基本完成；随着反应温度的升高，脱硫率也提高。

Results In the condition of obturation and humidity, Neisseria gonorrhoeae in the leucorrheas survived longer in middle quantity than in few and mass. The survival time of Neisseria gonorrhoeae was short in dryness. In a few quantity (10/ml), karyote could phagocytize Neisseria gonorrhoeae and shorten its survival time, but in the quantity above 300/ml, karyote could prolong its survival time.

结果 在密闭保湿状况下，白带标本中的淋球菌在中量时存活时间长，少量或大量时其存活力相对较低；在干燥状况下，淋球菌存活时间短；在菌量很少(10/ml)时，有核细胞可以吞噬淋球菌而导致淋球菌存活时间减少，但在菌量较多时（大于300/ml）时，有核细胞可以延长淋球菌存活时间。

The fresh weight and basal diameter of the cut curcuma flowers decreased with time after harvested without inserted them into water immediately. Thus, the vase life decreased. The even of the off-water time is only 30 minutes. One gram of fresh flower can absorb 30-40mg of fresh water, and the vase life increased 2-4 days if the stem base were recut, The curcuma flower per se after carting didn't posses peak of respiration and release of ethylene as well.

姜荷花切花采收后随著离水时问增长，鲜重与花茎基部直径渐减，瓶插寿命亦随之缩短，离水仅0.5小时切花即明显受要影响，花茎基部重新切除可增加10-20mg/gF.W的吸水量，而延长瓶插寿命，但同样随著离水时间延长而降低瓶插寿命。

The experimental results are as follows:(1) Without EAF the fouling resistance increase along with addition of time and change of the heat transfer coefficient is just contrary to the result. However, with EAF fouling resistance still enhances at the beginning of experiment and later, it gradually minishes after experiment has started for some time. Of course, the change of heat transfer coefficient still is contrary to the outcome. But when experiment lasts longer time, fouling resistance and heat transfer coefficient change in the same trend as the fore results at the beginning of the experiment. However, They all go to the tranquilization until the last.

实验结果表明：(1)没有经过电磁处理时，污垢热阻随着时间的增加而增加，换热系数随着时间的增加而减小；一旦经过电磁场的处理，污垢热阻开始时仍呈上升趋势，经过一段时间以后，便逐渐下降，换热系数的变化与此正好相反，即在实验开始时呈下降趋势，后来逐渐上升；当实验时间延长时，发现污垢热阻及换热系数在实验开始时的变化趋势与前面的实验结果基本相同，但到后来，二者的数值则分别均趋于稳定。
