Lately,It has emphasized that an asocial ,narcissistic personality has become characteristic of Americans,and that it is this type of personality that makes for the lack of well-being,because it prevent us from achiving consensus that would counteract a tendency to withdraw into private worlds.

最近有人强调美国人的性格特点是孤僻和自恋。正是这种性格使我们不能达到富足，因为它很难让我们有共同意识，有了共同意识人们才不会再退缩到自我的小天地中

Different kinds of flocculants have different capabilities. The flocculants produced by Aspergillus parasiticus is not steady for heat. The flocculating effect is best at acid conditions, and it is not acute for Ca〓. The flocculant can decolorize soluble dyestuff, even the active gorgeous red X-3B which is difficult to be decolorized, the decolor rate is 62. 1%. The flocculant produced by A-9 is steady for heat. It can flocculate Gaolin suspension well without synergistic effects of CaCl〓, and the dose is only 0.05ml/L. The obvious character of A-9's medium cultured for 3days is very viscosity, and viscosity is a mark for microorganism producing microbial flocculants.

不同的微生物絮凝剂具有不同的性能，寄生曲霉产生的絮凝剂对热不稳定，在酸性条件下絮凝效果好，对Ca〓不敏感，该絮凝剂对可溶性染料具有良好的脱色性能，即使是最难脱色的活性艳红X-3B，脱色率也达到62.1％。A-9产生的絮凝剂对热稳定，絮凝高岭土悬浮液时用量小，仅为0.05ml/L，且不需添加CaCl〓等助凝剂，明显优于其它微生物絮凝剂。A-9菌株培养3天的培养液的明显特征是粘性高，试验发现培养液的粘性与微生物絮凝剂性能有较好的对应关系，因此培养液的粘性可以作为微生物产生絮凝剂的重要标志。

Under the condition of different influent pH value and temperature, DO and ORP went up quickly by a big margin as the organic substance reached to nondegradation degree. This change characteristics of DO and ORP could indicate indirectly the degree of organic substance degradation.

原水在不同pH值与温度条件下，当有机物达到难降解程度时，DO和ORP均会迅速大幅度升高，DO和ORP的这一变化特点可以间接指示有机物降解的程度。

It was revealed that the balanced DO concentration appeared soon after the reaction stage starting,and DO level rose quickly in large range when COD was degraded to its nondegradation concentration under that condition,no matter that change the aeration rate or the MLSS concentration in large range,or change the initial COD concentration gradually or suddenly in the various experimental conditions.

结果表明，无论使曝气量或初始污泥浓度大幅度变化，还是逐渐或突然改变初始有机物浓度等各种试验条件，都会在反应阶段开始不久出现所谓平衡DO浓度现象；当有机物达到其难降解浓度时DO浓度迅速地大幅度升高。

In acid pulp, the depressing abilities of reagents on diaspore are in the order of hydroxamic acid starch＞dialdehyde starch＞carboxymethyl starch＞cationic starch＞primary starch. In addition, hydroxamic acid starch and carboxymethyl starch can activate kaolinite without influence on the recoveries of pyrophyllite and illite, so the two reagents have great potential and prospect to be the depressant of diaspore and the activator of kaolinite in bauxite reverse flotation.(3) By oximation of the copolymer of acrylamide and methyl acrylate, hydroxamic acid polyacrylamide is synthesized.

3对丙烯酰胺和丙烯酸甲酯的共聚物肟化制得氧肟酸聚丙烯酰胺，将它同非离子聚丙烯酰胺、阴离子聚丙烯酰胺、阳离子聚丙烯酰胺和两性聚丙烯酰胺分别应用于四种矿物的单矿物浮选试验，结果显示，改性聚丙烯酰胺对一水硬铝石、高岭石和伊利石均具有活化作用，其中，药剂对高岭石的活化最强，使它的回收率在整个pH值范围达到80％左右，在一定pH条件下超过一水硬铝石的回收率，解决了高岭石难浮选的问题。

However most organizers focus on economic benefits only, but ignore the quality and service. Therefore it will cause difficulty to attract visitors and reparticipate again.

然而许多主办单位仅著眼於经济效益，却忽略活动品质与服务水准，导致品质欠佳的活动无法达到原先设定之举办目的，更难吸引游客再次参与及衍生效益。

The results show that the coverage area of tungsten film on diamond surface is above 90% and the steady tungstenic carbides WC and W2C are created by this technology. The tungsten film coated on diamond is realized.

结果表明，该方法可在金刚石表面镀覆上一层覆盖面达到90%以上的金属钨膜，且生成稳定的碳化物WC和W2C，得到由难熔金属钨包覆的金刚石。

Subtropical and tropical area with high temperature and rainfall cause serious problems in pest and deceases, which need to use more amounts of pesticides.

尤其是身於亚热带地区的我们，在高温多湿的环境条件下，病虫之侵袭危害甚大，为求达到生产及商业品质之目标，农药之使用甚难避免。

Application of PMAC time-base control in the NC machining of noncircular section parts;2. This system solved the problem about the motion s devolving, it is the applying of function of PMAC on accurate and time-base controlling that ensured the synchronization of motion.

为解决感应加热过程中传送运动系统的运动交接难的问题，开发了一种以PMAC运动控制器为核心的运动控制系统，利用PMAC卡运动控制的精确性和时基控制的同步性解决了控制运动的交接问题，经试验证明所开发的系统可以达到控制要求。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
