根3是无理数的证明

根3是无理数的证明

根3是无理数的证明今天咱们来一起看看为什么根3是无理数呢?这就像一场有趣的数学冒险哦。

咱们先来说说什么是有理数。

有理数呀,就像是我们能很容易找到规律的数。

比如说,1呀,2呀,还有像1/2这样的分数。

你看,1就是1个,2就是2个,1/2呢,就是把1个东西平均分成2份,每份就是1/2,这些数我们都能很清楚地知道它们是多少。

那无理数呢?无理数就像是一群调皮的小怪兽,藏在数字的世界里。

根3就是其中一个。

咱们来假设根3是有理数。

那按照有理数的定义,它就可以写成一个分数的样子,就像a/b(这里的a和b都是整数,而且b不能是0哦)。

而且呢,我们可以让这个分数是最简分数,就是说a和b没有除了1以外的共同的约数,就像3/4这样,3和4除了1就没有别的数能同时整除它们了。

那如果根3 = a/b,那把两边都平方一下,就得到3 = a²/b²,然后再变一变,就成了a² = 3b²。

这时候,咱们来想个例子哦。

假如a是个整数,那a²就是a乘以a。

比如说a = 5的时候,a² = 5×5 = 25。

那a² = 3b²这个式子呢,就说明a²是3的倍数。

那什么样的整数的平方是3的倍数呢?咱们可以试试一些数。

像1的平方是1,不是3的倍数;2的平方是4,也不是3的倍数;3的平方是9,这就是3的倍数啦。

其实呀,只有a本身是3的倍数的时候,a²才会是3的倍数。

那咱们就可以说a = 3k(k也是个整数)。

把a = 3k代入到a² = 3b²里,就变成了(3k)² = 3b²,算一算就是9k² = 3b²,再变一变就是b² = 3k²。

这就和前面说a²的情况一样啦,这就说明b也是3的倍数。

可是呢,我们最开始说a/b是最简分数呀,现在a和b都是3的倍数,这就矛盾啦,就像我们说好了一件事,结果发现这件事根本做不到一样。

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?

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.

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#堆场水泥稳定碎石面积为64590㎡,,厚度0.4m,底部设计标高为+5.54m~+5.99m~+5.59m,顶部设计标高+5.94m~+6.39m~+5.99m。

在水泥稳定碎石施工之前,下承层必须验收合格。

二、施工流程:施工准备→测量放线→水稳拌和→运输→第一层摊铺→碾压→第二层摊铺→碾压→接缝处理→养生→报验三、施工工艺1、施工准备(1)根据施工图纸和施工组织设计文件由预算计算整体工程量并经审核后交由材料员组织材料进场,并于进场前送实验室进行试验检测合格后方可进场。

(2)施工前,测量现场地面标高,施工后测量完工后标高,均以测量报验单形式报监理业主审批。

(3)设专人进行天气预报的整理和发布,提前做好预警,保证后期施工工序顺利进行。

(4)建立施工台帐,对施工全过程进行合理、准确的记录,形成文字。

(5)施工所用特种装备需进行设备进出场统计,设备出厂合格证、检测报告和特种操作人员操作证书需齐全。

(6)进场工人进场前需接受相关安全教育及交底和技术交底。

2.施工放线本工程水泥稳定碎石基层下为12%灰土基层,施工前先清理下承层区域内杂物并洒水湿润。

施工测量控制点由业主提供的高程点引水准点至堆场施工沿线,间距为150m,分条分段进行施工,每条宽度约7.5m。

间距10m左右,立上钢筋桩,挂摊铺机用钢丝绳控制摊铺厚度及标高。

3.水稳拌合水稳站内注意事项:(1)站内人员严格按操作规程进行操作,以免发生机械故障和人员安全事故。

(2)在生产过程中,成品料应及时进行取样分析,及时调整,保证稳定材料的质量。

(3)设备在使用前应分别对部件进行单独的启动和停机试验,检查运转是否正常,正常后才能投入生产作业。

(4)在上料过程中不能出现混料现象。

施工程序及操作要点(5)上料应及时,不能出现缺料,缺级配现象。

(6)在开工前的材料进行抽样检测,根据测出的含水量,控制调节整体搅拌过程中的搅拌时间。

(7)进料必须经过实验人员的审核、签字方可计量、进场、堆放须由专人指引,对不合格的材料严禁入场,对材料不同,产地不同,规格不同的进行分别堆放,须备足生产所需的数量。

(8)加料顺序严格按照砂、石子、水泥、水进行。

(9)水泥稳定碎石中水泥用量不宜大于6%,采用标号较低水泥,本次施工采用普通硅酸盐P.O 32.5级水泥,20℃终凝时间在6小时以上。

根据设计要求的水泥稳定碎石无侧限抗压强度进行配合比试验,确定配合比中各种配料的实际掺量,使所用水泥和骨料均满足设计要求和规范规定。

方筛孔尺寸(mm)31.5 26.5 19 9.5 4.75 2.36 0.6 0.075 液限塑指通过百分率(%)100 90-100 72-89 47-67 29-49 17-35 8-22 0-7 <28 <9 集料的压碎值不大于30%,颗粒组成宜采用下表所示级配范围:4.水泥稳定碎石运输混合料的运输采用自卸汽车运输,运距超过5km以上时应覆盖运输,防止混合料表面水分损失较多而产生离析。

汽车运输不可在已完成的基层上行驶,当不得已在已完成的铺筑上通过时,速度要缓慢,减少不均匀碾压或车辙。

卸料时慢卸,防止混合料离析。

5.摊铺采用摊铺机进行摊铺,通过两侧钢丝绳挂线来控制高程、坡度及平整度,确保质量。

控制摊铺机匀速摊铺,要求其速度控制在1.5m-1.8m/min,切勿停机停料或摊铺过快而影响平整度。

分两层摊铺,下层摊铺碾压成型后应尽快摊铺上层,而且上层摊铺前在下层面上洒水让其湿润,必要时考虑洒些水泥,增加两层联结,避免水稳层真的分“两层”而降低承载力。

摊铺过程中螺旋分料器分料不能过少,致使两侧参差不齐,人工培料而使两侧离析严重,也不能过多,要求其熨平板前料控制在2/3高度,松铺系数暂定为1.3,可根据实际情况加以调整。

6.碾压待摊铺全部完成后,采用20t振动压路机先静压2遍,再振动碾压4遍,最后再静压2遍。

整形的水泥稳定碎石基层,宜在水泥初凝前并应在试验确定的延时时间内完成碾压,并达到要求的密实度,同时没有明显的轮迹。

碾压过程中,如有“弹簧”、松散、起皮等现象,应及时翻开重新补充新料再压实,使其达到质量要求。

碾压时,后轮重叠1/2轮宽,压路机的碾压速度,振压4遍采用1.5-1.7km/h,静压采用2-2.5km/h。

在碾压结束之前,再终平一次,使表面顺适,终平应仔细进行,必须将局部高出部分刮除。

严禁压路机在已完成的或正在碾压的路段上调头和急刹车,以保证表面不受破坏。

7.接缝处理纵向接缝:应避免纵向接缝。

基层应分两幅摊铺,每个作业段压实后,施工程序及操作要点在与下一作业段的接茬处及时人工清除松散部分。

人工修接缝处碾压遍数根据实际情况做相应的增加。

一层与二层留出2m间隔,保证与下面水稳接茬处的结合严密。

8.横向接缝:(1)用摊铺机摊铺混合料时,不宜中断,如因故中断时间超过2h,应设置横向接缝,摊铺机应驶离混合料末端;(2)人工将末端含水量合适的混合料弄整齐,紧靠混合料放两根方木,方木的高度应与混合料的压实厚度相同;整平紧靠方木的混合料;(3)方木的另一侧用砂砾或碎石回填约3m长,其高度应高出方木几厘米;(4)将混合料碾压密实;(5)在重新开始摊铺混合料之前,将砂砾或碎石和方木除去,并将下承层顶面清扫干净;(6)摊铺机返回到已压实层的末端,重新开始摊铺混合料;(7)如摊铺中断后,未按上述方法处理横向接缝,而中断时间已超过2h,则应将摊铺机附近及其下面未经压实的混合料铲除,并将已碾压密实且高程和平整度符合要求的末端挖成与路中心线垂直并垂直向下的断面,然后再摊铺新的混合料。

8.养护及交通管制碾压完成并经压实度检查合格后,应立即开始养生。

采用洒水车淡水养生,保湿养生不少于7天,养生期内始终保持表面湿润,如遇过于干燥的天气,可以铺塑料薄膜,养生期满后,经检测合格即可进行下道工序施工。

在养护期间,禁止车辆在已完成的基层上行驶,养生期满后如不能及时进行上部结构施工,需继续洒水。

四、质量控制及工期保证措施1.施工前及时组织材料厂家保障材料供应,并联系实验室出具相关配合比报告。

2.混合料拌和均匀;3.应严格掌握水泥稳定碎石基层厚度和高程;4.应在混合料处于或略小于最佳含水量时进行碾压,直到达到按重型击实试验法确定的98%压实度;5.必须严密组织,采用流水作业法施工,尽可能缩短从加水拌和到碾压终了的持续时间;6.必须保湿养生,不得使水泥稳定碎石表面干燥,也不应忽干忽湿;职业健康安全环保技术措施详见《职业健康安全/环保技术交底》主要附件设计图纸HB1164/S4-2#2-3/4 其他施工草图附图1 其他配料单其他项目负责人技术负责人安全员质量员交底人班组确认序号姓名工种序号姓名工种1 142 153 164 175 186 197 208 219 2210 2311 24附图1+4.99+5.39+5.59+5.99水泥稳定碎石厚度400m m+6.39+5.99地基3#堆场+5.94+5.5458北侧南侧27职业健康安全/环保技术交底编号: 单位工程名称3#堆场工程施工内容水泥稳定碎石交底单位中国交通建设股份有限公司黄骅港矿石码头工程接受交底单 位测量班、试验、物资、施工队、技术员一、安全交底1.本工程施工工序下承层验收合格→测量放线→水稳拌和→运输→第一层摊铺→碾压→第二层摊铺→碾压→接缝处理→养生→报验2.本工程的施工危险源辨识:(1)机械施工不当易发生机械伤人事故;(2)司机与指挥人员配合失误易发生人员碰撞事故;(3)场地道路不通可能导致翻车,易造成人员伤害事故;3. 没有经过三级安全教育和参加技术交底的施工人员不得参加施工。
