『贰』 有关真空吸尘器方面的英语资料

A vacuum cleaner is a device that uses an air pump to create a partial vacuum to suck up st and dirt, usually from floors. Most homes with carpeted floors in developed countries possess a vacuum cleaner for cleaning. The dirt is collected by a filtering system or a cyclone for later disposal.

简介

Technology

A vacuum's suction is caused by a difference in air pressure. A pump reces the pressure inside the tube. Atmospheric pressure then pushes the air through the carpet and into the tube, and so the st is literally pushed into the bag.

Tests have shown that vacuuming can kill 100% of young fleas and 96% of alt fleas.

Configurations

Vacuum cleaner configurations:

* Upright vacuum cleaners take the form of a cleaning head, onto which a handle and bag are attached. Upright designs usually employ a rotating brush-roll, which removes dirt through a combination of sweeping and vibration. There are two types of upright vacuums; dirty-fan/direct air, or clean-fan/indirect air.

The older of the two designs, dirty-fan cleaners have a large impellor (fan) mounted close to the suction opening, through which the dirt passes directly, before being blown into a bag. The motor is often cooled by a separate cooling fan. Due to their large-bladed fans, and comparatively-short air-paths, dirty-air cleaners create a very efficient airflow from a low amount of power, and make great carpet cleaners. Their 'above-floor' cleaning power is less efficient, since the airflow is lost when it passes through a long hose.

Clean-fan uprights have their motor mounted after the bag. Dust is removed from the airstream by the bag, and usually a filter, before it passes through the fan. The fans are smaller, and are usually a combination of several moving and stationary turbines working in sequence to boost power. The motor is cooled by the airstream passing through it. Clean-air vacuums are good for both carpet and above-floor cleaning, since their suction does not significantly diminish over the distance of a hose, as it does in dirty-fan cleaners. However, their air-paths are much less efficient, and can require more than twice as much power than dirty-fan cleaners to achieve the same results.

The most common upright vacuum cleaners use a drive-belt powered by the suction motor to rotate the brush-roll. However, a less common design of al motor upright, often found in commercial vacuum cleaners, is available. In these cleaners, the suction is provided via a large motor, while the brush-roll is powered by a separate, smaller motor, which does not create any suction. The brush-roll motor can sometimes be switched off, so hard floors can be cleaned without the brush-roll scattering the dirt. It may also have an automatic cut-out feature, which shuts the motor off if the brush-roll becomes jammed, protecting it from damage.

* Canister (or cylinder) designs have the motor and bag in a separate canister unit (usually mounted on wheels) connected to the vacuum head by a flexible hose. Although upright units have been tested as more effective (mainly because of the beaters), the lighter, more maneuverable heads of canister models are popular. Some upmarket canister models have "power heads", which contain the same sort of mechanical beaters as in upright units, although such beaters are driven by a separate electric motor.

* Wet vacs or wet/dry vacuums—a specialized form of the canister vacuum—can be used to clean up wet or liquid spills. They commonly can accommodate both wet and dry soilage; some are also equipped with a switch or exhaust port for reversing the airflow, a useful function for everything from clearing a clogged hose to blowing st into a corner for easy collection.

* Back-pack vacs are commonly used for commercial cleaning: they allow the user to move rapidly about a large area. They are essentially canister vacuum cleaners, except that straps are used to carry the canister unit on the user's back.

* Built-in or central vacuum cleaners move the suction motor and bag to a central location in the building and provide vacuum inlets throughout the building: only the hose and pickup head need be carried from room to room; and the hose is commonly 8 m (25 ft) long, allowing a large range of movement without changing vacuum inlets. Plastic piping connects the vacuum outlets to the central unit. The vacuum head may either be unpowered or have beaters operated by an electric motor or air-driven motor.

The dirt bag in a central vacuum system is usually so large that emptying or changing needs to be done less often, perhaps once per year. The central unit usually stays in "stand-by", and is turned on by a switch on the handle of the hose, or the unit powers up when the hose is plugged into the wall inlet. Such a unit also proces greater suction than common vacuum cleaners, because a larger fan and more powerful motor can be used when they are not required to be portable. Another benefit of a central vacuum system is that unlike a standard vacuum cleaner, which blows some of the dirt collected back into the room being cleaned (no matter how efficient its filtration), a central vacuum removes all the dirt collected to the central unit. Since this central unit is usually located outside the living area, no st is recirculated back into the room being cleaned. In addition, because of the remote location of the motor unit, there is less noise in the room being cleaned than with a standard vacuum cleaner.

* Robotic vacuum cleaners move autonomously, usually in a mostly chaotic pattern ('random bounce'). Some come back to a docking station to charge their batteries, and a few are able to empty their st containers into the dock as well.

* Small hand-held vacuum cleaners, either battery-operated or mains powered, are also popular for cleaning up smaller spills.

* Drum vacuums are used in instrial applications. With such a configuration, a vacuum "head" sits atop of an instrial drum, using it as the waste or recovery container. Electric and Compressed Air powered models are common. Compressed air vacuums utilize the venturi effect.

Most vacuum cleaners are supplied with various specialized attachments, tools, brushes and extension wands to allow them to reach otherwise inaccessible places or to be used for cleaning a variety of surfaces.

Vacuum cleaner specifications

The performance of a vacuum cleaner can be measured by several parameters:

* airflow, in cubic feet per minute (CFM or ft³/min) or litres per second (l/s)
* air speed, in miles per hour (mph) or metres per second (m/s)
* suction, vacuum, or water lift, in inches of water or pascals (Pa)

The suction is the maximum pressure difference that the pump can create. For example, a typical domestic model has a suction of about negative 20 kPa. This means that it can lower the pressure inside the hose from normal atmospheric pressure (about 100 kPa) by 20 kPa. The higher the suction rating, the more powerful the cleaner. One inch of water is equivalent to about 249 Pa; hence, the typical suction is 80 inches (2,000 mm) of water.

The power consumption of a cleaner, in Watts, is often the only figure stated. Many North American vacuum manufacturers only give the current in amperes (e.g. "12 amps") and the consumer is left to multiply that by the line voltage of 120 volts to get the power ratings in Watts. The power does not indicate the effectiveness of the cleaner, only how much electricity it consumes. The amount of this power that is converted into airflow at the end of the cleaning hose is sometimes stated, and is measured in air watts: the units are simply watts; "air" is used to clarify that this is output power, not input electrical power. This is calculated using the formula:
cleaning power (air watts) = airflow (CFM) × suction (inches of water) / 8.5
= airflow (m³/s) × suction (Pa)

Air watts measured at the vacuum's motor can differ by as much as 50% (depending on the type of vacuum) from the air watts measured at the end of the hose. This is most noted in Central Vacuums.

Some smaller vacuum cleaners are light-weight, portable, and rechargeable, instead of using AC power.

当今好莱坞黑人影星中片酬最高、唯一能与老牌黑人影星丹泽尔-华盛顿一争高低的唯威尔-史密斯莫属。他年仅32岁，身高1米83，被人们称为“黑王子”，虽然只主演了为数不多的几部电影，但却被好莱坞紧紧地搂在怀中，并入住过白宫，真是令人惊叹。

威尔-史密斯1968年9月25日出生于美国的费城，父亲维拉-史密斯是个电气工程师，母亲卡罗琳是一所学校的员工，有一个姐姐，两个妹妹。作为家中的独子，他从小就十分机灵顽皮，加上他圆润的口音相当具有魅力，上小学时老师就送给他一个“王子”的绰号，不曾想他日后真成为了好莱坞的“黑人王子”。出众的天生嗓音和演唱才华，威尔从12岁就开始他的说唱事业。1985年他遇到了志同道合的朋友杰夫-汤恩斯，组成了二人重唱组，到各地登台演出，被称为“DJ爵士杰夫和新王子威尔”。1986年起先后录制了《Rock the House》和《He's the D.J., I'm the Rapper》两张白金唱片，在后一专辑中，威尔因金曲《父母就是不了解》(“Parents Just Don't Understand”)而获得了1988年格莱美音乐奖的最佳说唱歌曲奖，并被评为“明日之星”。在歌坛获得巨大成功之后，威尔-史密斯开始表现出对演戏的兴趣。1989年威尔碰到了华纳公司经理本尼-梅迪纳，他给了威尔一个试镜、念剧本的机会，威尔凭着他纯正的嗓音，发挥的异常精彩，本尼觉得威尔就是他们要找的人选，当即拍板决定上戏。

1990年，电视剧《贝莱尔的新鲜王子》(“The Fresh Prince of Bel-Air”)开始播放，并深受广大观众喜爱。《贝莱尔的新鲜王子》的成功使威尔-史密斯与众多好莱坞的演员建立起了亲密关系，为他日后在好莱坞的发展打下了一个良好基础。1992年威尔-史密斯与后来成为他太太的女友简达-萍姬一起来到了好莱坞。当年，威尔就初次登上了银幕，在影片《你在哪里过了一天》(“Where the Day Takes You”)中扮演一位残疾青年。1993年出演了影片《美国制造》(“Made in America”)，同年威尔还出演了影片《六级分裂》(“Six Degrees of Separation”)，在剧中扮演一个混入上流社会的骗子，表演自然流畅，影评界对其赞不绝口。但让他真正走红的还是在1995年与同为黑人演员的马丁-劳伦斯合演的一部惊险动作片《绝地战警》(“Bad Boys”)，他在剧中扮演穿着时髦的缉毒警探麦克-劳里，人们惊呼“除了迈克尔-乔丹，他们还没见过这样迷人的黑色男人”，此片令威尔大获成功。片酬上升到500万美元，片商也纷至沓来。1996年威尔-史密斯拍摄了一部科幻巨片《独立日》(“Independence Day”)，扮演英国海军陆战队上尉史蒂文-希勒，为地球的安危而全力出击。该片赢得了当年好莱坞票房收入冠军，也使威尔的身价倍增。1997年威尔-史密斯在巴里索伦费尔德执导的科幻影片《黑衣人》(“Men in Black”)中，扮演超人特警，一身黑衣、黑超墨镜，成为世界上最酷的警探。这个充满活力的黑人演员，把黑人角色演绎出从未有过的自信、轻松和充满魅力。此片上映后极受欢迎，好评如潮，在当年掀起了一股“黑衣”旋风，并一再创票房新高，位列全美最卖座电影的第十五位。威尔-史密斯以MIB(Men in Black，黑衣人)成为一代黑人偶像。这一年，威尔主唱了《黑衣人》主题曲后，又钻进录音棚，于11月份发行了自《Code Red》(1993年)以来的最新的一张专辑《Big Willie Sytle》。《独立日》和《黑衣人》的巨大成功，将他推上了好莱坞的前排，1998年替代汤姆-克鲁斯出演了惊险片《国家的敌人》(“Enemy of the State”)，扮演一位卷入一宗谋杀案的律师，票房收入不错，威尔的表现更加证明了他的演技，巨星的地位已经确立。1999年威尔又主演了巴里索伦费尔德执导的《西部狂野》(“Wild Wild West”)，扮演一名联邦特工詹姆斯-威斯特，在片中不断展示神奇武器和潇洒扮相，大话、脏字连篇，嬉笑怒骂成了他的招牌，此片反响一般。2000年威尔主演了体育题材的影片《贝格文斯传说》(“Legend of Bagger Vance”)，在剧中扮演一名掌握着完美击球动作、“神秘的黑人球童”贝格文斯，与马特-达蒙、莎莉-塞隆组合成“明星梦幻组合”，魅力实在难挡，上映后一举获得票房季军的佳绩。红运当头的威尔-史密斯，目前正紧张地投身于巴里索伦费尔德的新片《拳王阿里》(“Ali”)的拍摄中，这是两人的第三度合作。威尔将主演拳击界最富争议性的拳王阿里，展现重量级拳王阿里传奇的一生，这对他来说是一次全新的挑战。为了演好心中的偶像人物，威尔进行了密集训练，勤练肌肉和拳法，并增肥15公斤，以达到“重量级”。他的教练之一就是阿里本人，阿里很希望威尔不要把自己给演砸了。冲着阿里的苦心和颤抖的双手，威尔决心要把此片演好，极尽所能诠释一代拳王阿里，相信手脚利落的威尔在拳台上的表现不会让阿里失望。威尔主演《拳王阿里》的片酬将高达两千万美元，从此与好莱坞两千万美元身价的吉姆-凯瑞、汤姆-汉克斯等重量级明星齐名，成为有史以来片酬最高的黑人影星。此片将于明年6月前封镜，届时威尔能为观众带来惊喜吗？明年《拳王阿里》一杀青，威尔就会立即投入巴里索伦费尔德执导的《黑衣人2》(“Men in Black 2”)的拍摄。该片的主演仍由威尔史密斯和汤米李琼斯担纲，威尔-史密斯日前接受采访时称：“对于能够出演动作大片《黑衣人》续集感到非常兴奋”，并说剧本写得“简直棒级了”。续集讲述的是关于银河系间爆发的一场战争，打斗的主要场所也将移至太空，场面必定火爆。

威尔-史密斯年轻干练，拍电影、演电视、灌唱片，样样在行。他多才多艺、口碑极好，甚至还有竞选总统的想法。“长久以来，我一直在努力思考，设法当上第一任美国黑人总统。”他甚至表示“给我10年时间，我会当上美国总统的”。就在1999年的最后一夜他真与斯皮尔伯格等大牌影人一起进入了美国白宫，和总统克林顿共度千禧年之夜，着实风光了一回。在威尔-史密斯的电影事业刚要起步的时候，1992年他与服装设计师舍丽结为夫妻(不久他即与女友简达-萍姬前往好莱坞发展)，这段婚姻维持了三年就宣告破裂，他们的儿子特利由他负责抚养。1998年元旦前夜，威尔-史密斯与多年的女友简达-萍姬终于结为伉俪，他们举行的婚礼是当年好莱坞最为豪华的婚礼。两人婚后互敬互爱，感情甜蜜，威尔也沉静于家庭的欢乐中，同年夏天儿子杰登出世。去年11月，时值他的新片《贝格文斯传说》上映，他家中又再添一个新成员——女儿，真是双喜临门。
