电线是由一根或几根柔软的导线组成,外面包以轻软的护层;电缆是由一根或几根绝缘包导线组成,外面再包以金属或橡皮制的坚韧外层。

电缆与电线一般都由芯线、绝缘包皮和保护外皮三个组成部分组成。

常用电缆的特性如下:

CEF——乙丙橡胶绝缘氯丁橡胶护套,船用阻燃电力电缆。

CVV——聚氯乙烯绝缘,聚氯乙烯护套船用阻燃电力电缆。

氧舱电线常采用BV,BX,RV,RVV系列电线,其中:

BV——铜芯聚氯乙烯绝缘电线,长期允许温度65℃,最低温度-15℃,工作电压交流500V,直流1000V,固定敷设于室内、外,可明敷也可暗敷。

BX——铜芯橡皮绝缘线,最高使用温度65℃,敷于室内。

RV——聚氯乙烯绝缘单芯软线,最高使用温度65℃,最低使用温度-15℃,工作电压交流250V,直流500V,用作仪器和设备的内部接线。

RVV——铜芯聚氯乙烯绝缘和护套软电线,允许长期工作温度105℃,工作电压交流500V,直流1000V,用于潮湿,机械防护要求高,经常移动和弯曲的场合。

皮皮

电线一般电压低,截面小,外径也小。则电缆相反。这是广义上来讲,狭义上估计分的更细了!~

上海浦东电线电缆集团下属有:矿用公司、特种公司、分支公司、矿物质公司、船舶公司等17余家,国内外销售公司、品牌旗舰店、办事处300多家,以上海总部为中心,云南、广西、重庆、辽宁为四大生产基地、是以实业投资为主体,外向型、高科技、多元化的大型综合性集团企业。

里论外几

电线电缆是用以传输电(磁)能、传递信息、实现电磁能转换和构成自动化控制线路的基础产品。电线与电缆二者并无严格的区别,广义的电线电缆亦可称为电缆。

通常将结构简单无外护套、外径较小的产品称为电线,将结构复杂、有坚固密封外护套、外径较大的产品称为电缆。电线的主要结构为“导体+绝缘”,电缆的主要结构为“导体+绝缘+护套”;导体一般由铜、铝或其合金制成,绝缘和护套一般由橡胶、聚乙烯、聚氯乙烯等材料制成。下图为某款扁电缆横切面图。

南yi

在国家标准GB/T2900.1-2008《电工术语 基本术语》中有明确定义(等同于国际电工委员会IEC60050-151标准)

GB/T2900.1-2008 3.3.47

电线:英文wire,又名“导线”。有或无外包绝缘的柔性圆柱形导体,其长度远大于其截面尺寸。(注:导线截面可能有任何形状,但“导线”一词一般不用于条状或带状导体。)

IEC60050-151-12-28:flexible cylindrical conductor,with or without an insulating covering,the length of which is large with respect to its cross-sectional dimensions

NOTE-The cross-section of a wire may have any shape,but the term "wire" is not generally used for ribbons or tapes.

GB/T2900.1-2008 3.3.55

电缆/光缆:英文cable。具有外保护层并且可能有填充、绝缘和保护材料的一个或多个导体和/或光纤的组合体。

IEC60050-151-12-38:assembly of one or more conductors and/or optical fibres,with a protective covering and possibly filling,insulating and protective material.

区别:电线以1根为主要型式(单芯线)(若为多根,则每根的用途目的一致,如多导体紧密或非紧密绞合,有或没有外护套的电线,俗称“多股软线”),护套不填充。电缆以多根为主要型式,单根护套填充/保护的,即为电缆。

慧慧

电线一般用于承载电流的导电金属线材。有实心的、绞合的或箔片编织的等各种形式。按绝缘状况分为裸电线和绝缘电线两大类。电缆是由一根或多根相互绝缘的导电线心置于密封护套中构成的绝缘导线。其外可加保护覆盖层,用于传输、分配电能或传送电信号。它与普通电线的差别主要是电缆尺寸较大,结构较复杂等。电线与电缆的区别在于电线的尺寸一般较小,结构较为简单,但有时也将电缆归入广义的电线之列。

cloud123

电线电缆是指用于电力、电气及相关传输用途的材料。“电线”和“电缆”并没有严格的界限。通常将芯数少、产品直径小、结构简单的产品称为电线,没有绝缘的称为裸电线,其他的称为电缆;导体截面积较大的(大于6平方毫米)称为大电缆,较小的(小于或等于6平方毫米)称为小电线又称为布电线。

马老四

电线是由一根或几根柔软的导线组成,外面包以轻软的护层;电缆是由一根或几根绝缘包导线组成,外面再包以金属或橡皮制的坚韧外层。

左迁

电线:通常把只有金属导体的产品和在导体上敷有绝缘层外加轻型保护(如棉纱编织层、玻璃丝编织层、塑料、橡皮等)、结构简单,外径比较细小、使用电压和电流比较小的绝缘线,叫做电线。

电缆:把既有导体和绝缘层,有时还加有防止水份侵入的严密内护层,或还加机械强度大的外护层,结构较为复杂,截面积较大的产品叫做电缆。

小菜G

电线与电缆的区别在于电信的尺寸一般较小,结构较为简单,但有时也将电缆归入广义的电线之列。

1、电缆与电线一般都由芯线、绝缘包皮和保护外皮三个组成部分组成。电线是由一根或几根柔软的导线组成,外面包以轻软的护层;电缆是由一根或几根绝缘包导线组成,外面再包以金属或橡皮制的坚韧外层。

2、两者并没有严格的界限。通常将芯数少、产品直径小、结构简单的产品称为电线,没有绝缘的称为裸电线,其他的称为电缆;导体截面积较大的(大于6平方毫米)称为大电线,较小的(小于或等于6平方毫米)称为小电线,绝缘电线又称为布电线

电缆一般有2层以上的绝缘,多数是多芯结。

可可

电线一般只有单层聚乙烯或聚氯乙烯绝缘材料包裹。

电缆有双层绝缘材料附着,如聚乙烯绝缘护套线,橡胶绝缘电缆(其中包括带金属保护铠装电缆)

gitcloud

电线就是家家户户用的电的线叫电线,更细,电缆线就用在高压上的线叫电缆线,耐冻耐牢粗壮。

max笔记

广义讲电缆也称之为电线

狭义讲电线指单芯无护套电线

电缆指多心有护套电线

wio

电线一般十平方是大的了电缆的平方和粗细都是够用的也是够粗的

英语问题!!高手场!

第一题中arrived并不缺宾语,所以不用which第二题中where是地点状语,主句缺一个地点状语。翻译:要做的就尽全力,半途而废从来不是正确的。第三题中which i think 是插入语,去掉后不影响句子意思,而is是句子的谓语动词。第四题我个人认为,as充当了两个句子成分,一个是后半句的主语,来指代前面的句子,还有一个意思就是:如同(仔细品一品,确实有如同的含义)。后半句翻译是:这在上文中已经被证明了。第五题中where指的是日用电器那个环境,在那个环境和场所内,电是用来发热的。第六题中in which指的是accident,在那个accident中有五十个人被杀,应该也可以用where.

什么是主语从句?后接动词什么形式,谓语用单双数?

主语从句 一、概述:在句子中起名词作用的各种从句统称为名词性从句。根据它们在句中的语法作用,这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。 二、 几个共性问题: 1.连接方式 (1) 在由连词that, whether, if引导的名词性从句中,引导词在句中不做成分,在宾语从句和表语从句中,that可以省略。 (2) 在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中,其连接代词在句中起名词性作用,担当一定成分。 (3)在由连接副词when, where, why, how引导的名词性从句中,其连接副词在句中作状语。 2.whether和if的区别 (1)whether在引导的主语从句中可以置于句首,而if则不能。 (2)whether可以与or not连用,or not可以紧跟在whether之后,也可以置于从句末尾;if一般不能和or not连用。 (3)表语从句、同位语从句和介词宾语从句(即在系词be和介词之后),只能用whether连接,而不用if。 (4)从句是否定式时,一般用if, whether很少用在否定式从句中。 例如:I don"t care if he doesn"t e . 如果他不来,我也不介意。 The problem is whether we can carry out the plan. 问题是我们是否能实施这项计划。 三、 主语从句 1.主语从句主要有三类: (1) 由连词that引导的主语从句。 例如:That you will win the medal seems unlikely. 你想获得奖牌看起来是不可能的。 That you are so indifferent bothers me. 你如此冷淡使我很烦恼。 That she survived the accident is a miracle. 她在事故中幸免于难简直是奇迹。 (2) 用连接代词或连接副词if, whether 引导的主语从句。 例如: Which of them escaped from the prison is still a mystery. 他们哪一个是从监狱里逃跑的,仍然是个谜。 When they will e hasn"t been made pubic. 他们什么时候来还不知道。 Whether she is ing or not doesn"t matter too much. 她来不来都无关紧要。 (3) 用关系代词引导的主语从句。 例如:What you need is more practice. 你所需要的是更多的训练。 What I want to know is this. 我想知道的就是这事。 Whatever we do is to serve the people. 我们无论做什么都是为人民服务。 主语从句可以直接放在主语位置上,也可以用it作形式主语, 而将从句放在句末(尤其是当谓语较短时)。 例如:That light travels in straight lines is known to all. 光沿直线传播,这是众所周知的事。 =It is known to all that light travels in straight lines. 众所周知光沿直线传播。 When the plane is to take off has not been announced . 飞机何时起飞还没有宣布。 = It has not been announced when the plane is to take off. 还没有宣布飞机何时起飞。 当what引导的主语从句表示“…的东西”时,一般不用it作形式主语。 错:It is a book what he wants. 对:What he wants is a book. 他想要的是本书。 如果带主语从句的句子是疑问式,则必须用it作形式主语的结构。 例如:Has it been settled who will be sent to carry out the task ? 谁将被派去执行这项任务决定了吗 ? 3.固定用法和译法 (1) It is +名词+从句 It is a fact that… 事实是…… It is good news that … ……是好消息 It is a that … ……是个问题 It is mon knowledge that … ……是常识 类似的名词还有:a pity;a wonder;a good thing; no wonder; surprise等。 例如:It is a mystery to me how it all happened. 这一切是怎么发生的是个谜。 It is mon knowledge that the whale is not a fish. 鲸鱼不是鱼,这是常识。 It is no surprise that Bob should have won the game. 鲍勃会赢得这场比赛,这不足为奇。 (2) It is +形容词+从句 It is necessary that … 有必要…… It is clear that … 很清楚…… It is likely that … 很可能…… It is important that … 重要的是…… 类似的形容词还有:strange; natural; obvious; true; good; wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while; surprising; interesting; astonishing, etc. 例如:It is obvious that conductors and insulators are both important in industry. 很明显导体和绝缘体在工业中都很重要。 It is doubtful whether she will be able to e. 她是否能来令人怀疑。 It was really astonishing that he refused to talk to you . 他拒绝和你说话真是令人惊讶。 It is essential that he should be here by the weekend . 周末之前,他应该到这里是必要的。 It seems obvious that we can not go on like this. 很明显我们不能这样下去了。 (3) It is +过去分词+从句 It is said that … 据说…… It is reported that … 据报道…… It has been proved that … 已证明…… It must be proved that… 必须指出…… 类似的过去分词还有:known; estimated; expected; believed; thought; hoped; noted; discussed; required; decided; suggested; demanded; made clear; found out,etc. 例如:It is thought that he is the best player. 大家都认为他是最好的选手。 It is estimated that the vase is 2000 years old. 据估计这个花瓶有2000年的历史。 It is used to be thought that a new star must be due to a collision between two stars. 过去一直认为新星是由于两颗星星之间碰撞产生的。 It has not been made clear when the new road is to be opened to traffic. 还没弄清楚这条路将开始通车。 (4) It +不及物动词+从句 It seems that … 好像是…… It happened that… 碰巧…… It follows that … 由此可见…… It has turned out that … 结果是…… 类似的不及物动词还有:seem, appear, occur, follow, happen, turn out, etc. 例如:It turned out that nobody remembered the address. 结果是无人记得那个地址。 It now appears that they are in urgent need of help. 看起来他们急需帮助。 It does not matter if I missed my train, because there is another later. 没有赶上这趟火车没有关系,稍晚还有一趟。 It happened that I saw him yesterday. 碰巧我昨天看见他了。 当“及物动词 + 宾语”较短时,也可用这种结构。 例如:It shocked me that Peter did not tell anybody where he was. 让我吃惊的是彼得没有告诉任何人他在哪里。 It does not interest me whether you go or not. 我对你去不去不感兴趣。 It +某些固定结构+ 主语从句。 例如:It doesn"t make too much difference (It doesn"t make any difference / It doesn"t alter the situation),whether it rains or not . 下不下雨都没有多大关系。 It does not make any difference whether it rains or not . 下不下雨没什么分别。 It does not make the least difference to me what you do. 对我来说你做什么都无关紧要。 Is it of much consequence to you that Mr. Wang has failed to do it ? 王先生没有做成这件事对你有什么重要影响吗?

D。由下文的like when taking your kid to the park or having dinner with yourwife可推断,此处是说某些“时刻(moments)”。55. A。上文提到人们在某些时刻可以把手机留在家里,也就是说人们有时实际上并不“需要(need)”来自脸谱网等的通知。56. D。由下文的wondering if someone"s trying to ... in an emergency可推断,Light Phone使人们在休息的同时不用“担心(anxiety)”别人会不会有急事与自己联系。57. D。由第四段中的the ability to receive forwarded calls from your phone可推断,Light Phone可以使使用者转接到打给智能手机的电话,因而使用者不必担心有人需要紧急“联系(reach)”他们。58. C。“如果(if)”享受生活的机会还不够吸引人的话,使用者随后还可以看到智能手机上所有的通知等。59. B。由下文的and notifications可推断,此处是指来自智能手机的不太紧急或重要的信息。故选emails。60. B。由上文的isn"t attractive enough可推断,使用者随后能够看到来自智能手机的电子邮件和通知,这就像是给使用者的“款待(treat)”。语法填空:61. it。考查代词。设空处指代上文的the closest U.S. port city to Europe,故填it。62. of。考查介词。consist of是固定短语,意为“由……组成”。63. is。考查一般现在时。由前句可知,设空处描述的是客观事实,故填is。64. overlooking。考查动词-ing形式作定语的用法。peninsulas与overlook(俯瞰)之间是逻辑上的主谓关系,且overlook所表示的动作正在进行,故填overlooking。65. became。考查一般过去时。由in the 18th century可知,become所表示的动作发生在过去,故填became。66. which。考查关系词。设空处引导非限制性定语从句,指代前面整个主句的内容,故填which。67. the。考查定冠词。序数词前要加定冠词the。68. geographical。考查形容词作定语的用法。设空处修饰名词position,故填形容词geographical。69. equipped。考查过去分词作定语的用法。equip与ships之间是逻辑上的动宾关系,且equip所表示的动作已完成,故填equipped。70. that。考查连接词。设空处引导宾语从句且从句中不缺成分,故填that

定语从句和主语从句的区别

定语从句:一:概说 1 定义:在复合句中起定语作用的从句叫做定语从句。 (定语从句一般放在它所修饰的名词或代词——即先行词之后) 2 种类; ⑴限定性定语从句:限定性定语从句对说明句子意义来说必不可少,如果省略句子意思不 完整,有时甚至会被歪曲,限定性定语从句不用“,”和句子的其他部 分隔开。 ⑵非限定性定语从句:非限定性定语从句对说明句子意义来说未必必不可少,如果省略 句子意思仍然完整,非限定性定语从句通常用“,”和句子的其他 部分隔开。 例句:①限定性定语从句:正在睡觉的那个男孩是汤姆。 The boy who issleeping is Tom. ②非限定性定语从句:水,一种清澈透明的液体,很有用途。 Water,which is aclear liquid,has many uses. 3 限定性定语从句与非限定性定语从句的区别: ⑴限定性定语从句不能省略,如果省略,句意不完整; 非限定性定语从句可以省略,如果省略,句意仍然完整。⑵限定性定语从句不用“,”把它和句子的其他部分隔开; 非限定性定语从句用“,”把它和句子的其他部分隔开。⑶限定性定语从句可以用that引导; 非限定性定语从句不可以用that引导。⑷限定性定语从句的关联词有时可以省略(一般做宾语时省略); 非限定性定语从句的关联词不可以省略⑸限定性定语从句一般只能用来修饰先行词; 非限定性定语从句可以用来修饰先行词,也可以用来修饰整个句子或句子的一部分。 4 关联词:  ⑴关系代词(6个):who 谁(主语)whom 谁(宾语)whose 谁的(定语)which 哪个(主语,宾语)that (主语,宾语)as 像~(主语,宾语) ⑵关系副词(3个):when ~时候where 哪里why 为什么 主语从句主语从句一 定义 : 在复合句中起主语作用的从句叫做主语从句。二 位置: 一般与陈述句基本结构中的主语相同。但多数情况下用it做形式主语,而把主语从句放在主句之后,避免头重脚轻。三主语从句的种类(1) 由连词that引导的主语从句。 例如:That you will win the medal seems unlikely. 你想获得奖牌看起来是不可能的。That you are so indifferent bothers me. 你如此冷淡使我很烦恼。That she survived the accident is a miracle. 她在事故中幸免于难简直是奇迹。(2) 用连接代词或连接副词if, whether 引导的主语从句。例如: Which of them escaped from the prison is still a mystery.他们哪一个是从监狱里逃跑的,仍然是个谜。When they will come hasn"t been made pubic. 他们什么时候来还不知道。 Whether she is coming or not doesn"t matter too much. 她来不来都无关紧要。(3) 用关系代词引导的主语从句。例如:What you need is more practice. 你所需要的是更多的训练。What I want to know is this. 我想知道的就是这事。Whatever we do is to serve the people. 我们无论做什么都是为人民服务。主语从句可以直接放在主语位置上,也可以用it作形式主语,而将从句放在句末(尤其是当谓语较短时)。例如:That light travels in straight lines is knownto all.光沿直线传播,这是众所周知的事。=It is known to all that light travels in straight lines. 众所周知光沿直线传播。When the plane is to take off has not been announced .飞机何时起飞还没有宣布。= It has not been announced when the plane is to take off. 还没有宣布飞机何时起飞。当what引导的主语从句表示“…的东西”时,一般不用it作形式主语。错:It is a book what he wants.对:What he wants is a book. 他想要的是本书。如果带主语从句的句子是疑问式,则必须用it作形式主语的结构。例如:Has it been settled who will be sent to carry outthe task ?谁将被派去执行这项任务决定了吗 ?四 主语从句常用结构(1) It is + 名词 + 从句It is a fact that… 事实是……It is good news that … ……是好消息It is a question that … ……是个问题It is common knowledge that … ……是常识类似的名词还有:a pity;a wonder;a good thing; no wonder; surprise等。例如:It is a mystery to me how it all happened.这一切是怎么发生的是个谜。It is common knowledge that the whale is not a fish. 鲸鱼不是鱼,这是常识。It is no surprise that Bob should have won the game. 鲍勃会赢得这场比赛,这不足为奇。(2) It is + 形容词 + 从句It is necessary that … 有必要……It is clear that … 很清楚……It is likely that … 很可能……It is important that … 重要的是……类似的形容词还有:strange; natural; obvious; true; good;wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while;surprising; interesting; astonishing, etc.例如:It is obvious that conductors and insulators areboth important in industry.很明显导体和绝缘体在工业中都很重要。It is doubtful whether she will be able to come. 她是否能来令人怀疑。It was really astonishing that he refused to talk to you .他拒绝和你说话真是令人惊讶。 It is essential that he should be here by the weekend .周末之前,他应该到这里是必要的。It seems obvious that we can not go on like this.很明显我们不能这样下去了。(3) It is + 过去分词 + 从句It is said that … 据说……It is reported that … 据报道……It has been proved that … 已证明……It must be proved that… 必须指出……类似的过去分词还有:known; estimated; expected; believed;thought; hoped; noted; discussed; required; decided; suggested; demanded; madeclear; found out,etc.例如:It is thought that he is the best player. 大家都认为他是最好的选手。It is estimated that the vase is 2000 years old. 据估计这个花瓶有2000年的历史。It is used to be thought that a new star must be due to a collision between twostars. 过去一直认为新星是由于两颗星星之间碰撞产生的。It has not been made clear when the new road is to be opened to traffic.还没弄清楚这条路将开始通车。(4) It + 不及物动词 + 从句It seems that … 好像是……It happened that… 碰巧……It follows that … 由此可见……It has turned out that … 结果是……类似的不及物动词还有:seem, appear, occur, follow, happen, turnout, etc.例如:It turned out that nobody remembered the address. 结果是无人记得那个地址。It now appears that they are in urgent need of help. 看起来他们急需帮助。 It does not matter if I missed my train, because there is another later.没有赶上这趟火车没有关系,稍晚还有一趟。It happened that I saw him yesterday. 碰巧我昨天看见他了。***** 当“及物动词 + 宾语”较短时,也可用这种结构。例如:It shocked me that Peter did not tell anybody wherehe was.让我吃惊的是彼得没有告诉任何人他在哪里。It does not interest me whether you go or not. 我对你去不去不感兴趣。***** It +某些固定结构+ 主语从句。例如:It doesn"t make too much difference (It doesn"t make any difference / It doesn"t alter the situation),whether it rains or not . 下不下雨都没有多大关系。It does not make any difference whether it rains or not . 下不下雨没什么分别。It does not make the least difference to me what you do.对我来说你做什么都无关紧要。Is it of much consequence to you that Mr. Wang has failed to do it ? 王先生没有做成这件事对你有什么重要影响吗?

Throughout history there have always been people who can make other people laugh

Throughout history there have always been people who can make other people laugh. Early clowns often both annoyed and delighted listeners with their comments and songs. They were not the silent performers seen in today"s circus rings. Clowns lost their voices when the big three-ring circuses made it impossible for the audience to hear them.Circus clowns give performances in various ways. Walk-around clowns use an animal or something, like a huge rubber hammer, as part of their performance. A carpet clown moves around, talking with the audience and performing while the acts change in the rings. Then there are acrobatic clowns, riding clowns, juggling clowns and others.Everything a clown does looks easy, but it is not. Making people laugh can be hard work. Clowns must be in good physical condition to prevent injuries. Each funny move is carefully timed and well-rehearsed (排练). Most clowns have also been trained as acrobats, jugglers or aerial artists, and many include such skills into their acts.Generally, there are three types of circus clowns—whiteface, auguste and character. Each has a special makeup and clothes. Each has a typical act as well.The neat whiteface is usually a strict, in-charge character who sets up the punch line (the point of a joke) with a partner who is typically an auguste. His facial makeup is neatly detailed in red or black, and his clothes look so loose with a ruffle around the neck.Old circus stories have it that the auguste clown got his name from a German nickname for someone who is clumsy, acting in a careless and stupid way. The auguste wears light-coloured makeup, but white is used around the mouth and eyes, and there"s a big red nose. This clown performs a great deal of humour. An oversized suit or baggy trousers allow freedom of movement for all the clumsy acts. He also wears big shoes.Character clowns perform as different characters—cowboys, grandmothers or concert conductors. The most famous character clown, however, is the tramp (流浪汉). Tramps wear different styles of makeup and torn clothes. Some tramp clowns are happy-go-lucky. Others are extremely sad. Still others act like gentlemen who just happen to be out of money.1. By saying that clowns “lost their voices”, the author means they ________.A. became silent to avoid annoying peopleB. began to perform silently because of larger audiencesC. realized audience members often spoke another languageD. discovered that three-ring circuses were becoming more popular2. How is Paragraph 3 mainly developed?A. By describing details. B. By listing effects.C. By making comparison. D. By giving explanations.3. If a clown is dressed in baggy clothing, which set of clowns does he belong to?A. The auguste and the whiteface. B. The walk-around and the tramp.C. The carpet clown and the cowboy. D. The riding clown and the conductor.4. In what way is the whiteface different from the auguste?A. He has a larger audience. B. He wears more attractive clothes.C. He performs in a special circus ring. D. He plays a leading role in performances.5. Why did the author write this article?A. To give some basic facts about clowns. B. To express his opinion on circus clowns.C. To tell readers about the history of clowns. D. To describe the hard work circus clowns do.答案:AACDD

was to be expected as

楼主理解有些偏差1文章整体为过去,这里用过去将来时表将来,说得通2be expected被动,主语是人,后边给出是settler3as是有词组与expect构成be expected as,可是这里行不通(如果硬要说成是搭配的话,后边的那些单词完全孤立,语法错误)……as这里引导一个状语从句,as相当于“当什么什么时候”或者表示伴随,意为“随着”。再之后的eventually引导分词状语,表结果……句子分析完毕说个题外话,一般这些文章中的被动式比较多,搞得迷惑得很,建议楼主直接主动理解,别按照原文翻译,效果更好:例如:随着,居住者对这片土地的侵占,他们对动物(鹿)的(需求)状况更加严重……

1、制作U盘启动盘,进入PE模式,运行DiskGenius,看能不能找到你的固态硬盘,很好识别,看容量就可以,如果可以找到,点击右键直接格式化,不要用快速格式化。2、第二步,如果你的固态硬盘是启动盘,将其设置为“活动”主分区,机械硬盘全部转换为逻辑分区。3、如果进入PE不能识别固态硬盘,打开机箱,更换数据线或者端口。4、排除以上问题后,还是读取不了,估计是写保护了 ,需要维修了。当然问题不大的话,可以用DiskGenius的磁盘坏道修复程序进行修复,不过时间较长,你的耐心等待,一般修复完毕就可以使用了,注意备份资料。你需要用到优盘去装系统,先把机械重新格式化掉 因为第一次安装新硬盘 会检测原来系统有引导 会默认取消bootmgr100m 。所以固态没有这个引导了 你只能把机械格式化 固态重新装个系统,关于bios不用设置。bootmgr引导会自动首选第一个检测到的系统而自动启动(不过你现在开机可以使用快捷用固态启动,因为固态没有引导 所以你可以利用bios快捷启动了,按我上面方法才能修改启动盘)、将固态硬盘连接到主板的SATA0接口,将机械硬盘连接到SATA1,然后重启电脑即可识别。如果仍无法识别,我们可以将机械硬盘先取下,只留一个固态在主板上再进入bios里看看能不能识别,如果可以识别在bios里设置后关机,把机械硬盘装上重启就可以了。如果还是没有办法识别,我们就进入bios里找到:load setup defaults,回车,把bios里的设置重置一遍就可以了。如果上述方法都不行,很有可能是固态硬盘没有分区所导致的,我们只需要进入PE系统里将固态硬盘分一区就可以解决问题了。最后仍无法识别的话,就要考虑固态硬盘是否损坏了,因为固态硬盘比较脆弱,使用寿命也比较短,使用大概五六年了就很有可能是损坏导致的。
