3 4指南各项目标及建议

3 4指南各项目标及建议最近在做“3 4指南各项目标及建议”这块，有点心得要说说。

这“3 4指南”啊，目标看起来就挺复杂的。

先说这其中的3个大目标吧。

我觉得第一个目标就是得理清框架，就像建房子得有个蓝图一样。

我刚开始的时候就很懵，完全不知道从哪儿下手。

有一次啊，做一个小项目就得按照这个3 4指南来，结果第一步就卡壳了。

我当时就瞎搞，到处乱找资料，完全没有章法。

后来我觉得啊，对于这种要理清框架的目标，一开始就得静下心来好好研究指南的介绍文档，哪怕是枯燥也得看进去。

虽然这个建议听着简单，但做起来真不容易。

还有就是多向有经验的人请教，我就找了个以前做过类似的前辈，他一点拨，我就感觉思路清晰多了。

不过呢，我也知道这个方法有局限性，因为不是随时都能找到这么合适的人请教。

替代方案嘛，就是在网络论坛上搜搜相关的分析帖子。

我感觉第二个目标呢，是操作起来要细致。

我记得我在做某个环节的时候，因为太粗糙了，导致后面很多流程都得返工。

这就好比做饭，盐放多了想补救就很难了。

所以我得出的经验就是，每一步操作，都要先在脑子里过一遍可能会出现的问题。

比如说，我后来会在做之前先写一个小的步骤大纲，然后对照着这个大纲一一执行，每执行完一步就检查一下。

但是这个也有不好的地方，就是太费时间。

那替代的方法呢，就是和团队里的小伙伴互相检查，这样说不定能发现自己没看到的问题。

还有啊，第三个目标，我觉得是得有灵活应变的能力。

行业里变化太快了，这3 4指南虽然明确了方向，但难免会遇到新情况。

我有次遇到突发问题，就按照老的指导死板地做，结果亏大了。

当时我就意识到，要根据实际情况，灵活地运用指南里的要求。

我是怎么做的呢？我会定期去关注市场动态呀或者行业新规则之类的东西。

你想啊，就像开车似的，路上有个坑，你得绕开啊，不能就傻愣愣地往前开。

不过呢，关注这些信息也很耗费精力。

所以还可以参加一些同行的交流会，别人遇到新情况的解决方式可能会给你带来启发。

再说说这里面的4个小目标吧。

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。

3的数字代表什么意思有什么含义

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.

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.

lino3受热分解方程式

lino3受热分解方程式小朋友们呀，今天咱们来聊聊一个特别有趣的化学小知识，就是关于lino3受热分解的方程式哦。

你们知道吗？化学就像一个魔法世界，各种物质在不同的条件下会发生奇妙的变化。

lino3这种物质呢，就像是一个等待被触发的小魔法盒。

当给它加热的时候，它就开始展现自己独特的变化啦。

就好像我们烤小饼干一样，小饼干在烤箱里会从软软的面团变成香香脆脆的饼干。

lino3受热的时候也会发生改变。

它受热分解会变成两种新的东西呢。

lino3受热分解会产生li2o和no2还有o2。

想象一下呀，lino3这个小团体，在热量这个特殊的力量下，就像小伙伴们要分开去做不同的事情啦。

一部分变成了li2o，就像一群小伙伴重新组合成了一个新的小团队。

而另外一部分呢，变成了no2和o2。

no2是一种有点特别的气体，o2呢，那可是我们很熟悉的氧气呀，我们呼吸就需要氧气呢。

我给你们讲个小故事吧。

有一个小化学精灵，它看守着lino3这个宝藏。

有一天，火焰精灵来捣乱，给lino3带来了很多热量。

这时候，lino3这个宝藏就开始变化啦。

它里面的一部分元素就像被魔法棒点了一下，变成了li2o这个新的宝藏，另外的元素就变成了像小气泡一样的no2和像我们身边看不见却很重要的空气朋友o2。

我们可以把这个变化写成一个方程式，就像写一个魔法咒语一样。

这个方程式就是2lino3→li2o+2no2+o2。

这个方程式就像是这个魔法变化的说明书，告诉我们lino3受热的时候到底发生了什么神奇的事情。

化学世界里还有很多这样有趣的魔法变化呢。

就像我们搭积木一样，不同的小积木（元素）可以搭成各种各样的形状（物质），在不同的条件下（比如加热、加其他物质等），这些形状又会重新组合，变成新的东西。

所以呀，化学是一个充满惊喜和奇妙的世界，大家可以慢慢去探索哦。

Text A offers an enlightening analysis of non-verbal communication across different cultures. The authors, Edward T. Hall and Mildred R. Hall, show us that cultural barriers could be overcome by increasing our awareness of cultural differences and by learning about the different ways in which we behave in different societies.
While culture is learned through practice and socialization, Text B provides a counter example to demonstrate the result of non-socialization. As you read the text, you can consider the importance of socialization for you to survive and develop your potential in a particular society.

新标准大学英语综合教程3 unit3 课文翻译

新标准大学英语综合教程3 unit3 课文翻译Unit3Active reading 1我们是怎样听音乐的我们都按照各自不同的能力来听音乐。

但为了便于分析，如果把听的整个过程分成几个组成部分，那么这个过程会更清晰一些。

从某种意义上来说，我们听音乐有三个不同的层次。

由于缺乏更好的术语，我们姑且把它们命名为：（1）感官层次；（2）表现层次；（3）纯音乐层次。

把听的过程机械地分割为以上三个假想的层次，唯一的好处是让我们更清楚地了解自己是怎样听音乐的。

听音乐最简单的方式是为了去获取乐声带来的纯粹的愉悦感，这是音乐的感官层次。

在这个层次上，我们只是听音乐，不做任何思考。

我们打开收音机，一边做着其他的事情，一边心不在焉地沉浸在音乐中。

乐声本身的魅力带我们进入一种无需思考的美妙心境。

令人意外的是，许多自认为是合格的音乐爱好者在听音乐时过多地使用了这一层次。

他们去听音乐会是为了忘却自我。

他们把音乐当成一种慰藉，一种逃避，由此他们进入了一个可以忘却日常生活的理想世界。

当然，他们也没有在思考音乐。

音乐允许他们离开现实，到另一个地方去做梦，因为音乐而做梦，做有关音乐的梦，却从没有真正欣赏过音乐。

的确，乐声的魅力是一种强大而原始的力量，但是你不该让它占据你过多的兴趣空间。

感官层次是音乐的一个重要层次，非常重要，但并不是音乐的全部。

音乐存在的第二个层次就是我所说的表现层次。

一提到这个问题，我们马上就进入到一个颇具争议的领域。

作曲家总是设法避开有关音乐表现方面的讨论。

斯特拉温斯基不是曾经声称他的音乐是一个“物体”，是一件有自我生命的“东西”，除了纯音乐性的存在之外没有任何别的含意吗？斯特拉温斯基这种不妥协的态度可能源于这样的一个事实：有那么多的人尝试着从众多的音乐作品中读出完全不同的含意。

确实，要准确地说出一部音乐作品的含意已经很难了，要肯定并确定地说出来，还要使每个人对你的解释都感到满意，是难上加难。

但我们不该因此走到另一个极端，不能去剥夺音乐“表现”的权利。

3 三级配电

第三节供配电系统与配电装置一、三级配电系统施工现场用电工程的基本供配电系统应当按三级设置，即采用三级配电。

（一）三级配电系统基本结构三级配电是指施工现场从电源进线开始至用电设备之间，应经过三级配电装置配送电力，即由总配电箱（一级箱）或配电室的配电柜开始，依次经过分配电箱（二级箱），开关箱（三级箱）到用电设备。

这种分三个层次逐级配送电力的系统就称为三级配电系统。

配电系统采用放射式和树干式，它的基本结构如以下框图。

（二）系统的设置原则三级配电系统应遵守四项基本原则：即分级分路原则，动照分设原则，压缩配电间距原则，环境安全原则。

1、分级分路(1) 从一级总配电箱（配电柜）向二级分配电箱配电可以分路，即一个总配电箱（配电柜）可以分若干分路向若干分配电箱配电；(2) 从二级分配电箱向三级开关箱配电同样可以分路，即一个分配电箱可以分若干支路向若干开关箱配电。

(3) 从三级开关箱向用电设备配电实行“一机一闸”制，不存在分路问题。

即每一开关箱只能连接控制一台与其相关的用电设备（含插座）。

按照分级分路原则的要求，在三级配电系统中，任何用电设备都不得越级配电，总配电箱和分配电箱不得挂接其它任何设备，否则，三级配电系统的结构形式和分级分路原则将被破坏。

2、动照分设动力配电箱与照明分配电箱宜分别设置。

当动力和照明合并设置于同一配电箱时，动力和照明应分路配电，动力和照明开关箱必须分别设置，不存在共箱分路设置问题。

3、压缩配电间距压缩配电间距原则是指各配电箱、开关箱之间的距离应尽量缩短。

总配电箱应设在靠近电源的区域，分配电箱应设在用电设备或负荷相对集中的区域，分配电箱与开关箱的距离不得超过30m，开关箱与其控制的固定式用电设备的水平距离不宜超过3m。

4、环境安全环境安全是指配电系统对其设置和运行环境的安全要求，包括三种环境要求：使用环境、维修环境和防护环境。

要求如下:(1) 使用、维修环境：满足压缩配电间距原则。

配电箱、开关箱周围应有足够二人同时工作的空间和通道，不得堆放任何妨碍操作、维修的物品，不得有灌木、杂草。
