In this study, we isolate, purify and characterize endo-β-glucanase by Ascomycete Xylaria regalis. The cellulose-containing medium is used to induce the production of the cellulose-degrading enzymes. When these enzymes are produced at maximum level, we harvest and filtrate the culture medium. The filtrate is purified by anion exchanger column and hydrophobic interaction column (phenyl-650M). The purification fold of endo-β- glucanase increases 4.3 times, the specific activity approaches 3.7 unit/mg, and the recovery is 27.6%, respectively.

为了分离且纯化此株菌产生在培养基中的endo-β-glucanase，先将此菌在cellulose液态培养基中大量培养，在此酵素达到最高峰时，利用滤纸过滤将菌丝及菌液分开，收集粗酵素液，再经过阴离子交换树脂及疏水性层析管柱(Phenyl-650M)等步骤予以纯化，所得到最终酵素纯度为 4.3倍，比活性为3.7 unit/mg，回收率为27.6%。

By Faradic impedance technique,a significant increase of the interracial electronic transfer resist- ance R_ was determined when the SH-ssDNA probe/Au electrode hybridized with its comple- mentary sequence.

实验中对DNA探针的自组装时间、杂交温度、杂交时间和阻抗测量液等实验条件进行了观察和优化；通过选择自组装液中SH-ssDNA探针和RSH的浓度，减少DNA在金电极表面的非特异性吸附，同时保证金电极表面自组装的SH-ssDNA探针有合适的疏密度，提高了杂交效率。

It was presumed that treatment with NaOH could extracted LB-EPS from the surface of ceils so as to increase the hydrophobic property of cells, which was favorable to flocculation among sludge flocs and hence the membrane filterability of mixed liquor.

推测碱液处理使细胞表面的LB-EPS脱落，从而使细胞表面疏水性增加，有利于絮体颗粒之间的絮凝，从而有利于混合液膜过滤性的改善。

In this Ph. D. dissertation, reverse microemulsion method was fully used infabricating and modifying polyacrylamide with functional and high-relative moleculeweight. The copolymerization of 2-acrylamide-2-methylpxopanesulfonic acid, fluorescent monomer 4-methoxy-N-(2-N\', N\'-dimethylamino ethyl)naphthalimide alkyl chloride quaternary ammonium salt, fluorescentmonomer 4-(N\'-methyl-1-piperazinylallyl)-N-butyl-naphthalimide chloride quaternaryammonium salt, Cationic monomer dimethylethylammonium bromide and hydrophobical monomer octadecylacrylate with acrylamide and properties of the copolymers werestudied. The interaction between five polymers and Al_2O_3(012) crystal surface have beensimulated by Materials Studio 3.0 program package, binding energies and non-bondinteraction energies and deformation energies have also been acquired.

Cloud point extraction is related to the conventional liquid-liquid extraction. CPE based on the solubility and cloud point phenomenon of aqueous solutions of surfactants, upon alteration of the experimental conditions such as pH value of solution, ionic strength, temperature, and the solution is separated into phases, which results in the separation of hydrophobe and hydrophile.

浊点萃取(Cloud-Point Extraction， CPE)是近年出现的一种新兴的液-液萃取技术，它以表面活性剂胶束水溶液的溶解性和浊点现象为基础，通过改变实验参数，如溶液的pH值、离子强度、温度等引发相分离，从而将疏水性物质与亲水性物质分离。

Summing up the reasons for the above situation is that there is the possibility of transformation between the status of two contacts (Cassie state and the Wenzel state) on super-hydrophobic surface, which can be promoted in different external conditions.

观察水在制备的超疏水涂层表面冷凝和蒸发情况，发现液滴可以在极易滚落和被紧紧粘在表面上无法下流，这两种状态之间相互转化，出现上述现象的原因可能在于超疏水表面上的两种接触状态（Cassie态和Wenzel态）之间存在着相互转化的可能性，不同的外界条件可以促使向不同方向的转化。

When the condensate water temperature gradually increased, the membrane began to evaporate liquid-filled box, the membrane box pressure rise, driven diaphragm valve heart Needle Valves to move off in the condensate to saturation temperature before the trap is completely closed, the membrane box with the steam temperature change control valve switch, play a role in blocking the drainage steam.

当冷凝水温度渐渐升高，膜盒内充液开始蒸发，膜盒内压力上升，膜片带动阀心向关闭方向移动，在冷凝水达到饱和温度之前，疏水阀完全关闭，膜盒随蒸汽温度变化控制阀门开关，起到阻汽排水作用。有开阀温度低于饱和温度15℃和30℃两种膜盒供选择。& bellows steam trap &是由中国疏水阀网提供的国际阀门新闻，译文仅供参考。
