The investigation on the concentration of four haloacetic acid s during conventional water treatment process in waterworks and in drinking waters in North China showed that there were only dichloroacetic acids and trichloroacetic acids in waters,and the proportion of TCAA was from 52% to 90%.

对北方某自来水厂常规水处理过程及饮用水体中的4种卤乙酸质量浓度进行了调查，结果表明水体中只存在二氯乙酸和三氯乙酸，其中三氯乙酸所占比例较大，为52%~90%；常规水处理工艺对二氯乙酸有较为明显的去除效果，去除率在15%以上，而对三氯乙酸没有明显的去除效果，但总体而言其对卤乙酸有10%左右的去除率；预氯化对卤乙酸的产生起主导性作用，该处产生的卤乙酸占整个氯化过程产生的卤乙酸总量的60%以上，因此常规工艺有必要从预氯化工艺着手加以改进，来更好的控制卤乙酸的产生量。

The more the number of hydroxyl substitution in phenyl ring, the better the ability of scavenging DPPH free radical. That is, trihydroxy is better than dihydroxy, and dihydroxy is better than monohydroxy. Moreover, when the polyhydroxy exists in phenyl ring and it is ortho-position or para-position, the ability of scavenging DPPH free radical is better too.

当苯甲醯基的苯环上羟基取代数量越多，其清除DPPH自由基的能力越好，三羟基效果优於双羟基、单羟基，双羟基效果优於单羟基；而苯甲醯基苯环上若为多羟基且羟基的位置为邻位或对位的关系时，其在清除DPPH自由基的能力较佳。

In the business card printing and membership card manufacturing process, when post-drying dilative innovativeink, in your design will be increased on a three dimensional stereo effect, if appropriate, then using the expansive ink it can be used as a low-cost alternatives to produce an ornament.

In addition, like ascorbic acid, an important reducing substrate for H2O2 removal, but unlike diphenylene iodonium, an inhibitor of the H2O2-generating enzyme NADPH oxidase, PD98059 and TFP not only reduced exogenous H2O2 levels in guard cells in light, but also eliminated the H2O2 that had been generated during a dark period and promoted stomatal opening.

另外，和H2O2的产生有关的NADPH氧化酶的抑制剂二苯基碘的作用效果不同，而和H2O2的清除剂抗坏血酸的作用效果类似，PD98059和TFP不仅能够降低光下保卫细胞的外加的H2O2水准，而且还能清除由黑暗条件诱导的已经产生的H2O2，并能引起气孔开放。

The insulation of apparatus in the power system is often broken by the very fast transient overvoltagewhich is caused by the operation of disconnector in gas insulate substation In this paper, a new idea for the suppressing VFTO by ferrite is put forward, and the characteristic of ferrite is analyzed.

GIS中隔离开关操作时产生的特快速暂态过电压对电力系统及其设备的绝缘具有巨大的破坏力，本文提出了采用铁氧体来抑制GIS中隔离开关操作时产生VFTO的方法，分析铁氧体抑制VFTO的优点，对VFTO的抑制效果进行了实验研究和仿真分析，探讨了具有理想抑制效果的铁氧体参数的具体要求和对理想抑制参数的铁氧体尺寸的估算方法。

With the development of product placement in commercial movies,its powerful disseminative effects and wealth commercial value have been gradually profound understanding.

El Centro is input, simulation calculations are made on floating-peak tank with circular-ring energy dissipater. The research indicates this control system is effect to apply to decrease earthquake response. History time curves of displacement, absolute acceleration, shearing force and uplift angle are contrasted with and without control. The effect of sets of cirque costing-energy is discussed.

Result shows that the baffle of burner has very little influence on the total resistance characteristic; both the speed of rich side and lean side are affected by the angle of burner as a whole, furthermore, the lean side is influenced more greatly; the separation performance could be enhanced with the increase of burner's angle and the best separation effect could be acquired when the three baffles are dissymmetrically arranged.

结果表明，燃烧器挡板角度的调整对燃烧器的总体阻力特性影响很小；燃烧器挡板偏转对于燃烧器整体以及浓淡两侧的气流速度都有一定的影响，且对淡侧影响较大；燃烧器的浓淡分离效果随挡板偏角的增加而显著增加，且三挡板非对称布置的浓淡分离效果最好。

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase（Rf0.57、Rf0.63）(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.

通过对日本凹顶藻以不同溶剂的粗提、乙醇提取物的极性分离、不同极性的薄层层析和多糖的提取，进行抗菌试验的研究，发现95%乙醇和V甲醇：甲苯为3∶1的提取的活性物质具有较强的抗姬松茸的病原细菌活性，乙酸乙酯相对病原细菌的抑菌强于乙醇的粗提物，而水相基本无抑菌效果，乙酸乙酯相的两个带（Rf0.57、Rf0.63）浓度为0.1g/ml具有较强抗姬松茸病原细菌的活性，对假单孢杆菌抑菌圈达到19.3mm，水相层析带的抑菌活性较弱，多糖的粗提物配成0.25g/g的水溶液对姬松茸病原真菌有较好的抑菌效果对黑曲霉、桔青霉和绿色木霉的抑菌圈分别达到10.8 mm、7.9 mm、5.3 mm。

Our country can apply strategic trade policy to coal industry. This article has proven in our country the feasibility in tradition industry—the coal industry apply the strategic trade policy, simultaneously according to such assumption, uses the model of Dixit, with 2003 data in Chinese coal industry, examine the effect of tax rebate for export, Empirical study has proven showed that, tax rebate for export promote coal volume of exports, indeed shift the profit to our manufacturer and enhanced the national welfare.
