为什么我们会说一套做一套? The Attitude-Behaviour Gap: Why We Say One Thing But Do The OppositeIt's only natural to think a person's attitudes and behaviours are directly related. If someone says, while truly believing it, that they're not a racist, you'd expect them to behave consistently with that statement. Despite this, psychologists have found that the link between a person's attitudes and their behaviours is not always that strong. In fact people have a nasty habit of saying one thing then doing the opposite, even with the best of intentions. You see it all the time. People say they're worried about global warming and yet they drive around in a big gas guzzler. They say that money isn't their God, yet they work all the hours. They say they want to be fit but they don't do any exercise. The discovery of the extent of people's blatant hypocrisy goes back to 1930s America and the work of a Stanford sociology professor, Richard LaPiere. In the early 30s he was on a tour across California with some close friends who happened to be Chinese. LaPiere was worried that they would encounter problems finding welcoming restaurants and hotels because of his Chinese friends. Out of the 128 restaurants and hotels they visited, all but one served them courteously. At that time in the US there had been lots of stories in the media about how prejudiced people were against Chinese people. LaPiere and his friends were, therefore, pleasantly surprised to find that out of the 128 restaurants and hotels they visited, all but one served them courteously. Nowadays the fact that one place refused to serve them would rightly be considered an outrage - but those were different times. So it sounds like a happy ending: perhaps the papers had just exaggerated people's negative attitudes towards Chinese people? But when LaPiere got home he started to wonder why there was such a gap between what the newspapers were reporting about people's attitudes and their actual behaviour. To check this out he decided to send out a questionnaire to the restaurants and hotels they had visited along with other similar places in the area (LaPiere, 1934). The questionnaire asked the owners about their attitudes, with the most important question being: "Will you accept members of the Chinese race in your establishment?" The answers they could give were: Yes. No. Depends upon the circumstances. Incredibly 90% of respondents answered, no, they wouldn't accept members of the Chinese race into their establishments. Incredibly 90% of respondents answered, no, they wouldn't accept members of the Chinese race into their establishments. Imagine LaPiere's surprise when he looked at the results. People genuinely did say one thing and do the complete reverse. They didn't even select 'it depends'. What on Earth was going on? LaPiere himself argued that the problem lay in the questionnaire. The questions themselves cannot represent reality in all its confusing glory. What probably happened when people were asked if they accept Chinese people was that they conjured up a highly prejudiced view of the Chinese which bore little relation with what they were presented with in reality. Here was a polite, well-dressed, well-off couple in the company of a Stanford University professor. Not the rude, job-stealing, yobbish stereotype they had in mind when they answered the questionnaire. This study has actually been subsequently criticised for all sorts of reasons. Nevertheless its main finding - that people don't do what they say they will in many situations - has been backed up by countless later studies, although in more sophisticated fashion. The question is: why? It all depends on how you ask the questions. Many psychologists effectively agree with LaPiere that it all depends on how you ask the questions and what stereotypes people are currently imagining when they give their answers. In some ways an attitude is like a snapshot of the prejudices the respondent has available to memory just at the moment they are questioned. This has led to a whole raft of studies and theories searching for connections between people's attitudes and their behaviour. Many a lengthy tome has been dedicated to explaining the divergence. Some of the factors that have been found important are: Social norms. Accessibility of the attitude. Perceived control over behaviour. Despite these findings, the picture is extremely complicated and frustratingly inconclusive. Perhaps as a result interest in this area has been waning amongst psychologists. The exact way in which people's attitudes and behaviour are connected remains a mystery. All we can say with certainty is that people are frequently extremely inconsistent.查看更多 0个回答 . 2人已关注

节能型全径向串塔氨合成新工艺简介? 节能型全径向串塔氨合成新工艺简介 为满足合成氨装置挖潜增产、节能降耗的需要,南京国昌化工科技有限公司开发了节能型全径向串塔氨合成新工艺,在不改变原有合成系统的基础上,在原有的废热锅炉后串联一个由国昌自主开发的GC型Φ1800全径向合成塔和一台废热锅炉,利用提高出口氨含量、增加氨净值的方法提高产量,具有投资少、建设周期短、阻力低、见效快、占地少等特点。山东瑞星化工在对原Φ1800氨合成系统增产降耗改造时,率先采用了该工艺。投入运行后,串入的GC型Φ1800全径向合成塔达到了年产6~7万吨氨的生产能力,原系统日产合成氨由545吨提高到了751吨。 串塔工艺流程是:循环气经 循环压缩机 加压至25MPa~26MPa后,进入原1# 氨合成塔 进行氨合成反应,反应出来的气体(304.5℃)进入原1#废热锅炉,副产1.1MPa~1.3MPa的中压饱和蒸汽,1#废锅出口气体约195℃进入新增的2#氨合成塔,经下部换热器加热后,进入催化剂床层反应,反应气体换热后(245℃)出塔进入新增的2#废热锅炉,副产1.1MPa~1.3MPa饱和蒸汽后,降至195℃左右,再进入原合成系统的 热交换器 、水冷器等设备,分离出产品氨后,循环气重新返回循环压缩机,进入下一循环。 串塔工艺与新建大型装置、并联建设装置相比特点和优势在于: 1 产量提高30%。使用串塔工艺后,氨的产量大幅度提高。其中1#塔产量545吨/日,2#塔产量206吨/日,即2#塔使总产量提高了37.8%,实际产量达到设计值的124.85%,串联的2#合成塔具备了年产6万~7万吨氨的生产能力。 2 氨净值提高3%~5%。南京国昌化工科技有限公司开发的具有自主知识产权的GC-R002Y型氨合成塔内件,满足了串塔工艺的特殊要求,独特的专利技术——不均匀开孔的多孔板及鱼鳞板二次分布器结构,气体分布均匀,同柱面温差仅为9℃,使催化剂活性得到充分利用,从而保证了氨净值提高3%~5%。 3 系统阻力减少0.2Mpa以上。串塔工艺选用的GC-R002Y型氨合成塔内件,分上、下两段床层的径向结构,使气体多次折流,气固相得到更好地接触,更有利于氨合成反应的进行,同时配用低温、高活性的小粒度催化剂,从而提高了催化剂的活性系数,有利于氨的充分合成反应和提高氨净值。采用全径向结构,大大降低了催化剂床层的阻力,因此,在串入一台GC型全径向氨合成塔及另一台废热锅炉后,合成塔系统阻力得到有效控制。 4 能耗降低30%。由于系统阻力减小和氨净值提高,串联的合成塔出塔气量减少,同时因提高氨净值而增加的氨量在水冷凝器中已被冷凝,故循环机与冰机总电耗在改造前后基本相等。在生产中,改造前后循环机与冰机开用台数相同,但产量提高了30%以上,所以,吨氨循环机与冰机的功耗下降30%左右。 5 投资省、建设周期短、见效快。以山东瑞星串塔工程为例,投资与其他方案相比节省了30%以上,而且在保证原系统生产的前提下,利用原有的一些设备,不但对生产的影响很小,而且原有的设备得到充分利用,使投资的费用远低于其他扩大生产规模的方案。由于工程量较少,占地面积小,可以利用原有生产设备的空隙地方插入,避免了征地等麻烦,加上精心的布置,新增的设备与原来的设备连接十分紧凑,现场施工量减少,建设周期从设计施工至投产仅用不到一年时间。见效快的另一个方面是由于设计上下了很大功夫,包括氨合成塔内件、整个工艺的配置、催化剂的选型、升温还原方案等都是精心设计,使催化剂还原结束后,便可以立即投入生产。 查看更多 0个回答 . 4人已关注
