0.2MPa低压蒸汽如何综合利用? 楼上说的相当对,就这点量,上网没戏。只能偷偷自用。总之,发电是不划算的,如有可能可以考虑带个不太重要的设备(比如水泵什么的)。查看更多

关于电脱盐的一点疑问? 主要是控制注水量,破乳剂量,看电脱盐的混合效果!如果静态混合器的压降大那么混合效果就好,电脱效果也就好点,另外增加一下油在电脱罐的停留时间,可能能起到一定的作用!查看更多
2009年职称英语理工类AB级精选试题四? 2009年职称英语理工类ab级精选试题四—补全短文 第五部分:补全短文(每题2分,共10分) 阅读下面的短文,文章中有5处空白,文章后有6组文字,请根据文章的内容选择5组文字,将其分别放会文章原有位置,以恢复文章原貌。请将答案涂在答题卡相应的位置。 the arctic ice is thawing father christmas may have to move his “workshop” from the north pole because global warming is thawing the ice beneath his feet and his reindeers' feet as well. his “workshop” is in dire straits. the “platform” for the “workshop” is melting, said stefan norris of the world wildlife fund environmental group's arctic program. 来源:中国职称英语考试网 an eight-nation report by 250 scientists published recently predicted the arctic ocean could be ice-free in summer by 2100 because of a build-up of heat-trapping gases in the atmosphere, mainly from burning fossil fuels in cars or factories. the north pole is getting more and more inhabitable to father christmas. ___1___. young people learn that father christmas' “workshop” produces millions of gifts delivered by him on a flying, reindeer-drawn sleigh. hollywood movies like "the polar express" tried to make viewers believe that father christmas lives at the north pole. ___2___. the "fortress of solitude" is near the north pole that could be under threat in a warmer world. alan boldt, spokesman of the danish ministry of science, suggested ways to rescue father christmas. ___3___. another alternative, he argued, would be building some electrical facilities to ensure the ice stays on the north pole for him. "this should be a subject for the united nations," he said. “danmark could build windmills to provide father christmas with power." denmark says father christmas’s real home is greenland, which will help, denmark thinks, to strengthen its position in claiming the sovereignty over the pole. ___4___. "doesn't he already speak danish?" boldt said frostily when asked if father christmas would be forced to learn danish if denmark won international recognition of its claim to the pole. last month's arctic report said the region is warming twice as fast as the rest of the globe, partly because dark ground or water, once uncovered, soaks up more heat than ice or snow. finland has been most favored by father christmas and it has about 500,000 tourists a year to visit its christmas center in rovaniemi in lapland6. ___5___. 来源:中国职称英语考试网 a.however, nordic nations all reject it by claiming that their countries are his home. b.therefore the north pole is the most attractive place in the world. c.if denmark’s claim were accepted internationally, it would have the legal right to search for oil and gas at the north pole. d.one of them would be building a giant floating ice rink for the workshop if the pole thaws. e.maybe father christmas has already moved to rovaniemi. f.he may have to move from the north pole within our children's lifetimes.  标准答案:f,a,d,c,e 来源:中国职称英语考试网 解  析:1.f “空1” 前面两个句子讲的是,受全球气候变暖的影响,北极的冰正在融化,估计到2100年夏天北极将成为无冰的世界。北极越来越不适合圣诞老人居住了。于是,读者或许会猜想,在这种情况下,圣诞老人该怎么办呢?选项 f 说, “he may have to move from the north pole within our children's lifetimes”,其意思与上文配合得天衣无缝,北极住不下去了,只能移居他处。因此 f 是答案。 2.a “空2”前面一句说,好莱坞电影 “极地快车”想让观众相信圣诞老人的故乡在北极。下面该填什么呢?选项a说, “however, nordic nations all reject it by claiming that their countries are his home”,北欧国家不同意这种说法,都声称自己的国家才是圣诞老人的故乡。意思和上文配得上,但意思正好相反。 所以,“空2”句子的句首用 however 与前一句接起来。a 是答案。 3.d “空3”前面一句说,丹麦科学部发言人提出拯救圣诞老人的几个办法。 “空3”的内容应该涉及具体的拯救办法。选项 d 符合这个要求。d 说其中一个办法是:如果北极的冰融化,就人工造个浮冰场地,上面可以承载圣诞老人的工场。 从上下文意思的连接上,从 one of them (指代前一句的 ways) 的用词上,都可以确定,d 是答案。 来源:中国职称英语考试网 4.c 选项 c 的句子一开始就用 “denmark’s claim”重复“空4”前面一句的 “claiming (to the sovereignty over the pole)”,从词汇重复上,我们可以判断,填入“空4”的句子应该是 选项 c 的句子。我们再从意思上分析一下。丹麦认为,说圣诞老人的故乡是格陵兰有助于加强丹麦声称自己拥有北极的主权的地位。选项 c 说,如果丹麦的这一要求得到国际社会认可的话,它就拥有合法的权利去勘测北极的石油和天然气。上下文意思是连贯的,所以 c 是答案。 来源:中国职称英语考试网 5.e “空5”前面一句说,“ finland has been most favored by father christmas and it has about 500,000 tourists a year to visit its christmas center in rovaniemi in lapland”。当看到 选项 e 中重复出现 rovaniemi,就知道 “空5”的位置上应该是选项 e 的句子。圣诞老人如此眷顾 rovaniemi,每年约有50万游客来参观 rovaniemi 的圣诞中心。e 的句子说 “maybe father christmas has already moved to rovaniemi (说不定圣诞老人已经移居罗瓦涅米了) ”,是对前一句 “眷顾”的颇有风趣的总结,也是对与“空1”的句子 “he may have to move from the north pole within our children's lifetimes” 遥相呼应。选项 e 是本题的答案。查看更多

关于双回路和双电源? 双回路供电一般是指某一负荷的电源有两回,此电源接自上级配电所不同的开关,正常运行时由其中一回电源供电,另一回处于备供状态;当一回电源停电时,由用户侧的自动切换装置将电源进行切换,保障负荷的不间断供电; 双电源供电一般特指两回电源来自不同的变电站(或配电所),这样就不会出现两回电源同时失压的情况,这种模式一般运用在特别重要的用户供电上,例如机场、火车站、医院等(上述场所还具备自行发电能力)!查看更多
