三角形的三遍关系

三角形的三遍关系
嘿，朋友！咱们今天来聊聊三角形的三边关系，这可是个有趣又神
奇的话题。

你想想看，三角形就像一个稳定的小家庭，三条边就如同家里的三
个成员，它们之间的关系可重要啦！要是关系不和谐，这个“家庭”可
就不稳定咯。

那这三边到底有啥关系呢？简单来说，任意两边之和大于第三边。

这就好比三个人手拉手，其中两个人手拉手的长度必须比第三个人伸
出的手臂长度更长，不然怎么能拉得住呀？
比如说，有三条边分别是 3 厘米、4 厘米和 5 厘米。

那 3 + 4 是不是大于 5 呢？当然啦！3 + 5 也大于 4 ，4 + 5 更是大于 3 。

这三边就能组
成一个稳定的三角形，就像一个和谐美满的小家庭。

可要是三条边是 1 厘米、2 厘米和 4 厘米，那 1 + 2 小于 4 ，这就好比两个小个子的人想拉住一个大力士，怎么可能拉得住呢？所以这三
边就组不成三角形。

再想想，如果两边之和等于第三边会怎样？那不就成了一条直线嘛，哪还有三角形的样子！
咱们在生活中其实也能找到三角形三边关系的影子。

你看那建筑工
地上的脚手架，不就是利用三角形的稳定性来保障工人的安全吗？要
是三边关系不合理，架子不就晃晃悠悠，多危险呐！
还有那自行车的车架，不也是三角形结构嘛，要是三边关系不对，
骑起来还不得散架？
所以说呀，三角形的三边关系可不是简单的数学知识，它和咱们的
生活息息相关。

咱们可得好好掌握，不然在解决问题的时候，不就像
没头的苍蝇到处乱撞啦？
朋友，明白了三角形三边关系的重要性和奇妙之处了吧？掌握好它，能让咱们在数学的世界里畅游得更欢快，在生活中也能更聪明地应对
各种问题！。

No hard evidence exists to support that tale, but in any case, by the sixth Awards Presentation in 1934, a Hollywood columnist used the name in his column.3. Walt Disney was honored with one full-size and seven miniature statuettes on behalf of his animated feature Snow White and the Seven Dwarfs.1.T hey are possibly boyfriend and girlfriend.2.In a restaurant.3."It doesn't really matter, does it? I haven't got anything better to do, have I?""I've only been waiting for over an hour.That's all" "After all, my time isn't reallythat important, is it?" well, at least It waslucky you found a barrage to repair yourcar4. If the statuettes don't meet strict quality control standards, they are immediately cut in half and melted down.5.The large boxes are shipped to the Academy offices via air express, with no identifiable markings.The Oscar statuette, designed by MGM's* chief art director Cedric Gibbons, depicts* a knight holding a crusader's* sword, standing on a reel of film with five spokes, signifying the original branches of the Academy: Actors, Writers, Directors, Producers, and Technicians.Born in 1928, years would pass before the Academy Award of Merit was officially named "Oscar". Industry insiders and members of the press called the award "the Academy statuette", "the golden trophy" or "the statue of merit". The entertainment trade paper, Weekly Variety, even attempted to popularize "the iron man". The term never stuck.A popular story has been that an Academy librarian and eventual executive director, Margaret Herrick, thought the statuette resembled her uncle Oscar and said so, and that as a result the Academy staff began referring to it as Oscar.No hard evidence exists to support that tale, but in any case, by the sixth Awards Presentation in 1934, Hollywood columnist Sidney Skolsky used the name in his column in reference to Katharine Hepburn's first Best Actress win. The Academy itself didn't use the nickname officially until 1939.Since its conception, the Oscar statuette has met exacting uniform standards - with a few notable exceptions. In the 1930s, juvenile players received miniature replicas* of the statuette; a ventriloquist* Edgar Bergen was presented with a wooden statuette with a moveable mouth; and Walt Disney was honored with one full-size and seven miniature statuettes on behalf of his animated feature Snow White and the Seven Dwarfs. Between 1942 and 1944, in support of the war effort, Oscars were made of plaster. After the War, winners turned in the temporary awards for golden Oscar statuettes.The traditional Oscar statuette, however, hasn't changed since the 1940s, when the base was made higher. In 1945, the base was changed from marble to metal and in 1949, Academy Award statuettes began to be numbered, starting with No. 501.Approximately 50 Oscars are made each year in Chicago by the manufacturer, R. S. Owens. If they don't meet strict quality control standards, the statuettes are immediately cut in half and melted down.Each award is individually packed into a Styrofoam* container slightlylarger than a shoebox.Eight of these are then packed into a larger cardboard box, and the large boxes are shipped to the Academy offices in Beverly Hills via air express, with no identifiable markings.On March 10, 2000, 55 Academy Awards mysteriously vanished en route from the Windy City* to the City of Angels. Nine days later, 52 of stolenstatuettes were discovered next to a Dumpster* in the Koreatown section of Los Angeles by Willie Fulgear, who was later invited by the Academy to attend the Oscar 2000 ceremonies as a special guest.For eight decades, the Oscars have survived war, weathered earthquakes, and even managed to escape unscathed* from common thieves. Since 1995, however, R. S. Owens has repaired more than 160 statuettes. "Maybe somebody used chemicals on them to polish them and the chemicals rubbed right through the lacquer* and into the gold," explains the company president. "Or maybe people stored them someplace where they corroded." Although he stresses that the statuette is made to endure, Siegel offers this sage advice to all Oscar winners: "If it gets dusty, simply wipe it with a soft dry cloth." Exercise A Pre-listening QuestionEvery January, the attention of the entertainment community and of film fans around the world turns to the upcoming Academy Awards, the highest honor in filmmaking. The annual presentation of the Oscars has become the Academy of Motion Picture Arts and Sciences' most famous activity.

This guy is a dictator and so we have to seewhat he says." The president says the Iraqi leader has a choice to make: disarm peacefully or be disarmed by force: "If Saddam Hussein does not comply to the detail of the resolution, we will lead a coalition to disarm him. It is over. We are through with negotiations. There is no more time. The man must disarm. He said he would disarm. He now must disarm." Mr. Bush spoke with reporters while touring the Washington D.C. police department, a tour designed to highlight his plan to create a cabinet level Department of Homeland Security.

In an interview with Radio Monte Carlo's Arabic service Thursday, Mr. Blair said war could be avoided, if Iraq agreed to disarm."The situation is very clear. If Saddam Hussein agrees to disarm Iraq of all chemical, or biological or nuclear weapons programs and capability, then conflict would be avoided, and his duty is to cooperate fully with the inspectors to tell them exactly what material he has, to cooperate and comply with them in the eradication of that material."The prime minister said he wanted to speak directly to the Iraqi people to try to dispel* what he called myths that have arisen between Christians and Muslims. He said the dispute with Iraq is not about the West versus the East or about oil, but about weapons of mass destruction.Exercise ADirections: Listening to the news item and complete the summary.This news item is about British Prime Minister's stand on the Iraqi issue.Exercise BDirections: Listen to the news again and complete the following sentences.1.Prime Minister Blair warned that Saddam Hussein would suffer theconsequences unless he cooperated with the UN weapons inspectors.

The Security Council gave Iraq this last opportunity to disarm or face serious consequences, a euphemism* for possible war. The United States says it will make sure Iraq disarms, one way or another.But Mr. Blix* emphasizes that his inspectors will not determine the courseof events in the region. He says they will visit suspected sites, conduct interviews with Iraqi scientists, ferret* out information and report back to the Security Council for its members to decide.As for US and British intelligence reports, which the Bush administration says proves that Iraq has banned weapons, Mr. Blix says he is not going into Iraq with pre-conceived ideas of what is there.The next test for Iraq will be December 8th, the deadline for Iraq to present a full accounting of its weapons programs. If Iraq presents, in effect, a blank sheet, Mr. Blix says, he would expect the United States to put its evidence on the table, so it can be verified.Iraq has persistently maintained it does not have the banned weapons. The latest such assertion came in a letter to the UN this week, in which Baghdad accepted the latest Security Council resolution setting out the parameters* for what experts say will be the most intrusive inspections in Iraq, so far.After the preliminary technical work starting Monday, Mr. Blix says, he expects the first wave of inspections to start November 27th. Two months later, he is required to report to the Security Council on Iraq's performance.Exercise ADirections: Listening to the news report and complete the summary.This news report is about Mr. Blix's weapons inspections in Iraq.Exercise BDirections: Listen to the news again and fill in the blanks with the missing words.Mr. Blix emphasizes that his inspectors will not determine the course of events in the region.

3#楼建筑物高度为104.7m，3#楼地下二层，4#楼地下一层，地上均34层；结构形式为剪力墙结构。

本工程施工用电总电源在施工现场内(4#楼西北角配电房)，供电容量暂定3个630KV A，由建设单位提供，目前，用电回路已基本确定，用电负荷见用电机械设备表。

现场线路布置采用埋地敷设，整个配电系统采用TN-S系统敷设，室外分段用总分配电箱接至用电设备，开关箱由末级分配电箱配电，动力和照明分路设置，各大型用电设备做重复接地。

2配电线路及电气装置2.1配电线路具体布置见《施工用电总平面布置图》。

本工程配电线路将严格按照JGJ46-2005施工现场临时用电安全技术规范设置配电线路及其保护设施，在每个施工用电回路分别设置独立的TN—S接零保护系统，在配电室总配电屏处作重复接地，并在配电线路中间处及未端处做重复接地，当部分总箱与分箱间距大于50米以上时，应增加一组重复接地。

接地线应与保护零线（PE线）可靠连接。

正常情况下，所有配电设施，用电设备的不带电金属外壳，均与PE线可靠连接。

专用保护零线由配电室的零线和第一级漏电保护器电源侧零线引出，单独敷设，不作他用，材料选用黄绿双色多组铜芯线，其截面要求不小于工作零线，与设备连接的保护零线截面应大于等于2.5mm2。

接地体采用DN50的镀锌钢管或L50×50镀锌角钢砸入地下2.5m，其顶部距地0.8m。

接地体安装完毕后，应做接地电阻测试，并做好记录归档，接地电阻阻值应不大于10Ω，其中配电总配电屏处接地电阻阻值应不大于4Ω。

2.2防雷系统在工程施工现场内所有外脚手架，均需安装防雷装置。

避雷针采用2米长DN25镀锌钢管。

引下线利用电气连接的设备金属结构体。

接地体安装同TN—S系统，接地电阻阻值不大于10Ω。

2.3配电装置本工程施工用电为三级配电两级漏电保护系统，配电装置主要有总配电箱，分配电箱（即二级配电箱）和开关箱（即三级配电箱）三级，同时本系统遵循动力与照明系统分开的原则，分配电箱又分照明与动力两种。

配电箱（包括总配电箱、分配电箱）和开关箱箱体采用δ=2mm的钢板制作，其进、出线口设置在箱底部，且为光滑圆孔。

配电箱、开关箱均设PE端子板（可与箱体连接），以及加装N线端子板（与箱体绝缘），并必须设箱门配锁。

此外配电箱开关箱骨架为L30×30角钢制作，箱体为全封闭，箱门上方设10cm的挑檐，以防雨水落入。

根据固定式配电箱开关箱的下底与地面的垂直距离应大于1.3m，小于1.5m，移动式的配电箱、开关箱的下底与地面的垂直高度宜大于0.6m，小于1.5m 的规范规定，配电箱与开关箱下方设采用L50×50角钢制作的支脚，支腿高度固定式为1.3m，移动式为0.6m，箱体内外防腐，且外部统一刷黄色调和漆，并设电气标志。

总配电箱的电器配置：设熔断功能总隔离开关1个，总漏电保护开关1个，下设若干分路，每个分路设熔断功能隔离开关1个，漏电开关1个，漏电开关具有短路过载、漏电保护功能，其中总路隔离开关和空气开关为三级，分路漏电开关为4极（带工作零线），进线为三相四线，出线为三相五线。

分配电箱的电器配置与接线：分配电箱分为照明和动力两种，对于动力分配电箱，考虑到三相负荷及单相用电机具的通用性，设置总隔离开关及空气开关1只，若干三相四线动力分路，及一个单相二级动力分路，进出线均为三相五线，单相照明分配电箱，设置三相总隔离开关1只，三相空气开关1只，下设若干分路，每个分路设置双极隔离开关，及空气开关各1只，进线为三相五线，出线为单相三线。

开关箱的电器配置与接线：开关箱是临时用电工程的未级配电装置，根据其负载的不同，其配置分为二种型式，即：三相负载型，单相负载型，均设置隔离开关1个和具备短路、过载及漏电保护功能的漏电开关1只，进出线分别为三相五线和单相三线。

本工程采用二级漏电保护，一级为总配电箱漏电保护，另一级为开关箱漏电保护，根据规范规定，开关箱选用额定漏电动作电流不大于30mA漏电开关，对于在特别潮湿场所使用的开关箱，应选用额定漏电动作电流不超过15mA的漏电开关，漏电动作时间不超过0.1s。

根据“二级漏电开关的额定漏电动作电流和漏电动作时间，应作合理配合，使之具有分级分段保护能力”以免出现误动作的原则，总配电箱内漏电开关，宜选用额定漏电动作电流为50mA（或100mA）动作时间小于0.2s 的漏电开关。

2.4负荷计算本施工现场配电采用三级配电两级保护，整个工程按区划分为四个临时用电施工区，每个施工区临电主要由四路电组成，第一路负责施工现场机械设备用电，第二路生活区、办公区用电。
