1.变压器运行中如漏油、油位过高或过低,温度异常,音响不正常及冷却系统不正常等,应设法尽快消除。
2.当变压器的负荷超过允许的正常过负荷值时,应按规定降低变压器的负荷。
3.变压器内部音响很大,很不正常,有爆裂声;温度不正常并不断上升;严重漏油使油面下降,低于油位计的指示限度;油色变化过快,油内出现碳质;套管有严重的破损和放电现象等,应立即停电修理。
4.当发现变压器的'油温较高时,而其油温所应有的油位显着降低时,应立即加油。
5.变压器油位因温度上升而逐渐升高时,若最高温度时的油位可能高出油位指示计,则应放油,使油位降至适当的高度,以免溢油。
您好!这次我您不为别的,只是在生活中有许多问题困扰着我,于是便想到与您倾诉。曾几何时,雾霾进入了我们的生活,与它的每一次亲密接触,都让我们感到窒息;曾几何时,天空不再湛蓝,反而蒙上一层灰尘,没有阳光,连视线也受到阻碍;曾几何鸿,有多少动物被人类残忍的***害,而人类的***还在无线膨胀。人类,是否能维护自己赖以生存的家园呢?而地球母亲,您是否在黯然神伤,在痛恨人类的种种罪行呢?
前面提到雾霾,相信地球母亲应该有所了解。雾霾是特定气候条件与人类活动相互作用的结果,细微颗粒(PM2.5是形成雾霾的原因。PM2.5是指直径小于等于2.5微米的颗粒物,与我们一根头发丝比起来,它可小多了,甚至我们人眼是无法觉察它的存在的。但它的危害可不容小觑,肺癌就是因它而起。这可绝不是危言耸听,它就象一条寄生虫,攀附在人的肺泡上,短短几周就能***人于无形。
还记得发生在英国伦敦的烟雾事件吗?那时,人类才真正意识到您的惩罚,慢慢学会反思。那是的伦敦的天空,灰蒙蒙的,曾经的蓝天烟消云散,路人的能见度很低,连司机都需要警察拿着火把来辨别方向。人类因呼吸道感染死亡的人数,还在不断上升,这些都是人类在自食恶果。
而动物们的`生存空间越来越少。每年因为人类乱砍乱伐,动物的生存领域遭到空前破坏,有些动物濒临灭绝。生活在我国长江流域的白鳍豚,已经犯焉了两千多万年。科学家沿着长江沿线调查白鳍豚的数量,结果一头都没有看到。一个经历了漫长时间考验的五种,竟然在短短几十年濒临灭绝。还有些动物被端上餐桌,有的还被人类肆意捕***,人类为了满足一己私利已经蒙蔽了双眼。
针对以上时间,我想到几种办法:
(1应该减少PM2.5的排放,少烧煤等污染较大的资源
(2汽车尾气是污染空气的原因之一,减少汽车尾气,多种树来吸收二氧化碳
(3低碳出行,出行可选用自行车或公交车,少乘坐私家车
(4国家应该明禁止捕***动物的行为,对于某些濒临灭绝的物种,可以设立自然保护区
(5变废为宝,如用过的纸可以重塑为再生纸。
地球本不属于人类。然却需要人类。让我们还地球母亲一个美好的蓝天,让他永保青春。

电力变压器是一种改变交流电压大小静止的电力设备,是电力系统中核心设备之一。如果变压器发生故障,将影响电力系统的安全稳定运行。笔者结合10多年的工作经验和电力技术规程,就电力技术标准对变压器的运行维护和事故处理做以下论述。
关于尊严,无论你的地位尊卑、财富多寡、文化高低、体貌美丑、衣着丽陋、职务高低,人的自尊是神圣而不可侵犯的。人与人之间应该是平等的,都有各自的性格,各自的为人,各自的自信与尊严。古往今来,有多少人为了昭显自己的尊严而留下豪情壮志的诗篇……譬如“横眉冷对千夫指,俯首甘为孺子牛”的周树人,“仰不愧于天,俯不怍于人”的孟轲,“安能摧眉折腰事权贵,使我不得开心颜”的李太白……他们有哪个不是世人所推崇的?他们就是活得有尊严,有价值,有意义。
俗话说“士可***而不可辱”,这也就是说宁愿丢掉性命,也“不可自暴自弃自屈”,我们要活得有尊严。丢失了尊严,丢失了自尊,也就是丢掉了做人的根本,没有尊严就等于没有了骨气。当你不如意或遭遇不幸时,总有人刻意践踏你的尊严你的人格,而这时候你要挺起胸膛捍卫尊严,不要让尊严受辱。别人的尊重要使你更坚强而非一味退让,懦弱屈服。维护尊严是你不受污辱的保障,不要让别人的不尊重成为尊严的枷锁。没有人可以污辱你,让你蒙羞。珍惜每一位可以称做朋友的人,因为那是可以让漂泊的心驻足的地方,也是上苍赐给最美丽的缘份。
古人说:“少成若天性,习惯如自然。”坏习惯是我们打不开的心锁;坏习惯是我们转不过的'弯,好习惯要保持,坏习惯要改正,永远别让坏习惯左右我们的未来。霍元甲说过:“人的地位虽有高低之分,但不应有人格上的贵贱之别。”尊严是一个民族的血脉,是一个民族的灵魂。没有尊严的人尚且行尸走肉,没有尊严的国家又将何去何从?相信大家都看过十二集大型纪录片《大国崛起》。在列强用鸦x和大-炮打开中国的大门的之后,将整个中国几乎搜刮一空。中国陷入了前所未有的窘境。经过了百余年艰苦卓绝的斗争,终于,一个昔日的泱泱大国再度在世界的东方崛起!
太在乎自己,亦是一种自我伤害,只有把自己放到这个残酷的世界中,去打拼,去历练,去忍受,最终你才能含泪播种,含笑收获。有人说:这个世界是蹂躏、践踏、埋葬我们尊严的地方,是产生并破碎、制造并毁灭我们梦想的地方。在别人维护你的尊严之前,不要妄谈尊严;在梦想没有成真之前,不要痴迷幻想。生活总以一种高压的姿态,肆意考验着我们脆弱的神经,让我们叹息或者窒息。这个世界真的很拥挤,我们难以寻找一方精神的栖息地。与其在风雨中逃避,不如在雷电中舞蹈;即使淋得透湿,也是领略生命的快意。
不要抱怨与哀叹;不必嫉俗与愤世,只有当心灵坚强了,心头那些洪水才会慢慢退去。曾数次击败反法同盟,建立了不可一世的功业的拿破仑,在征服一个小国家后,在这个国家的君主面前趾搞气昂地说:“臣服于我,就能得到这世界上任何你想要的东西。”岂料那君主说道:“我只想得到你脚下的那一寸土地。”尊严是上限,它是人精神领域最高贵的部分,不容许人轻易触碰,因此拿捏尊严的程度,尺度对我们来说至关重要。尊严,有时就像个顽皮的孩子,既不可过于溺爱,又不能过于严厉。当你对他微笑时,他也会给你一个更甜美的回应。
尊严要建立在相互信任的基础上,如果一个连信用都没有,那他何谈让别人尊重自己。让我们跟着奥运的步伐一同踏上尊严之旅,让尊严照亮整个世界!人生路上,挫折是难免的,低潮是必然的,孤独与寂寞如影随形。总有寄人篱下的时候,总有遭人诽谤与暗算的时候。这时候你必须冷静,要懂得潮涨潮落,波谷波峰的道理,只要你能够耐心等待,受得了折磨,守得住底线,一切都会证明,生活不会抛弃你,命运不会舍弃你。当你损害了对方的尊严时,实际上就是打中了他最薄弱的部位,这怎能让人忍受。所以说,为人处事最重要的就是尊重对方,维护对方的尊严。
一个有人格尊严的人,必定的是尊重一切有尊严的人格。同样,如果你侮辱了一个人,就等于侮辱了一切人,也侮辱了你自己。春秋时齐国连年灾荒,有个姓黔敖的富户在路边设了一个粥摊来周济逃荒的穷人。一天,黔敖看见一个人用袖子蒙着脸,没精打采地走过来,就高声喊道:“喂,来吃粥。”来人抬眼看着黔敖说:“我因为不吃嗟来之食才落到这样的地步。”说完他辞谢了黔敖又向前走了,终于饿死在路边。这个故事告诉我们,再小的人或事都是有尊严的,任何想践踏他人尊严的人不过是自取难堪。尊严是做人的下限,只有维护自己及保全他人尊严的人,才会得到他人的尊重。
Nowadays, many famous university campuses have become one of the popular tourist attractions. It has been shown on TV and on the radio that every year thousands and thousands of middle school students visit Tsing Hua University and Peking University and other famous universities in China. In the place far away from the capital city, the local students also visit the universities famous in their own province.
So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists? Different people have different opinions. On one hand, some people argued that it is a good thing for the students to visit the famous university campus in that it can enable the middle students to get more information about the university and they can have enough time and opportunity to prepare themselves with the chance to get into the university. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the public tourism will have negative effect on the universities because it will not only do harm to the environment but also to the intellectual atmosphere.
In my opinion, the tourism to the universities is not a good thing. The campus is mainly a place for study. With the increasing tourism on the campus, it will ruin the spiritual atmosphere in this learning field.
首先,提纯范文 “谋篇布局”及结构模板。
第一段:提出问题或现象。Nowadays, … … have become one of the popular … …. It has been shown on TV and on the radio that … ….
第二段:正反列举人们的看法。So far as the present situation is concerned, is it a good or bad thing to … …? Different people have different opinions. On one hand, some people argued that it is a good thing for … … in that … …. On the other hand, some people hold a negative view about this phenomenon. In their opinion, … … will have negative effect on … … because it will not only do harm to … … but also to … ….
第三段:摆明自己观点。In my opinion, … … is not a good thing. … … With the increasing … …, it will ruin … ….
其次,提纯范文“段落写作”。
段落写作分为统一性,连贯性和完整性三方面。
统一性(unity:段落开头的主题句应该做到不可太宽泛,也不可太具体,做到有较强的概括性才能使下文做到有的放矢的展开。范文第二段首句以设问的方式提出一个问题is it a good or bad thing就有很强的概况性。下文自然会一方面从好的方面说明,另一方面从坏的方面说明。
连贯性(coherence:关联词是使文章段落之间相互连贯的必要条件。范文中nowadays, on one hand, on the other hand, in one’s opinion即以“启承转合”递进的顺序是文章条理清晰,层层展开。
完整性(completeness:以设问句“So far as the present situation is concerned, is it a good or bad thing to open the university campus for tourists?”开头,这是平时较少运用的段落写作方式——设问法。“On one hand … …. On the other hand, … ….”是段落写作分类列举法的典型用法。
再次,提纯范文“句子写作”。
1. It has been shown that … …
类似句型:It is known to us that … …
It is said that … …
It is reported that … …
It is controversial that … …
2. “… … Tsing Hua University and Peking University and other famous universities … …。”——并列句。并列句是简单的复杂句。但其运用方法并不简单,注意练习并接句的使用,会使句子显的更加饱满。
3. enable v. 使…能够
I gave him full directions to enable him to find the house.
4. in that = because
表“因为”的连词还有since, for, as,如:
The boy was absent because he was ill. = The boy was absent since he was ill.
此句以我们常用的人称开头,句式简单,我们可以通过把since提前改变句式,如:
Since the boy was ill, he was absent. 句式多样化。
最后,提纯范文“措辞”。
1. attraction n. 具有吸引力的事情。
2. thousands and thousands 成千上万的
形容“多”的表达方法:millions and millions
a multitude of
a great deal of
a large amount of
plenty of
many a
3. “some people argued that … …”中的“argue”并不是“讨论,辩论”的意思,而是“认为”。
I argue that … …
I maintain that … …
I claim that … …
I insist that … … = I think that … …
I hold that … …
I assert that … …
I assume that … …
4. negative adj. 否定的.,相反的
hold negative view = hold opposite opinions
5. phenomenon n. 现象
social phenomenon 社会现象
natural phenomenon 自然现象
6. intellectual adj. 聪明的= intelligent, bright, clever
(选词策略:使用最近所学的单词,如intellectual > intelligent > bright > clever
在分析并掌握范文之后,我们需要运用范文知识练习仿写。笔者运用2005年12月范文中的模板结构仿写了2006年12月的四级作文,以供参考:
1. 许多人喜欢在除夕夜看春节晚会
2. 但有些人提出取消春节晚会
3. 我的看法
Nowadays, the Spring Festival Evening has become one of the popular topic and attractions during every traditional New Year’s Eve. It has been shown on TV and on the radio that every year thousands and thousands of Chinese people appear to be accustomed to enjoying the sights and sounds of a brilliant feast, while gathering with their beloved family.
However, an increasing number of people have voiced different opinions towards it. So far as the present situation is concerned, is it a good or bad thing to cancel the Spring Festival Evening? Different people have different opinions. On one hand, some people argued that it is a good thing to amuse the audience in that it is composed by a numerous adequate programs, such as the emotional song, the graceful dance, the funny short sketch, the amusing comic dialogue, the delightful magic, and the marvelous acrobatics and so on. On the other hand, some people hold a negative view about this phenomenon. In their opinion, the Spring Festival Evening will have negative effect on the family harmony because it will not only do harm to having the talks between family members on the Spring Festival Eve but also to enjoying the gourmet meal in a fancy restaurant.
In my opinion, the Spring Festival Evening is a good thing. It may not remain a must for all people, but it can bring us a strong sense of festivity and serve as an alternative among the variety of holiday activities. With the increasing audience of the Spring Festival Evening, it will ruin a distinctive culture during the Spring Festival vacation.
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。

Secondly,of course, taking exercise more often and taking good sleep to build your body are wise choices for you to reduce the risk of being infected.
Last but not the least, if you are unlucky to be infected with the slight flu cold, try to stay at home,and take some medicine. Do pay attention to your daily body temperature. If you have a high fever, go to the hospital without delay for further treatment. Make sure you are not expected to come back to school before the cold or flu is cured.
Only by doing like this can you prevent or defeat the A flu in the end.
