1-1/2^2=(2+1)(2-1)/2*2
1-1/3^2=(3+1)(3-1)/3*3
----
1-1/2004^2=(2004+1)(2004-1)/2004*2004
1-1/2005^2=(2005+1)(2005-1)/2005*2005
原式=(1*2*3*----2004*2006)/(2*2*3*4*---2005)
=2006/2*2005
=1003/2005

吃瓜留子 诸葛亮不仅能种出好庄稼,而且还有一手种西瓜的好手艺.襄阳一带曾有这么一个规矩:进了西瓜园,瓜可吃饱,瓜子不能带走.传说这条“规矩”也是当年请葛亮留下来的. 诸葛亮种的西瓜,个大、沙甜、无尾酸.凡来隆中作客和路过的人都要到瓜园饱饱口福.周围的老农来向他学种瓜的经验,他毫不保留地告诉他们瓜要种在沙土地上,上麻饼或香油脚子.好多人都来问他要西瓜种子,因为以前没有注意留瓜子,许多人只好扫兴而归.第二年,西瓜又开园了,他在地头上插了个牌子,上面写道:“瓜管吃好,瓜子留下.” 诸葛亮把瓜子冼净、晒干,再分给附近的瓜农.现在,汉水两岸沙地上的贾家湖、长丰洲、小樊洲的西瓜仍有名气,个大、皮薄、味沙甜.有些地方还遵守那条“吃瓜留子”的老规矩. 神机妙算救后代 这件事情的真否无法考证,从记载来看,可能性还是有的. 相传,诸葛亮在临死前对后代说:“我死后,你们中的一个将来会遇到杀身大祸.到那时,你们把房拆了,在墙里面有一个纸包,有补救的办法.” 诸葛亮死后,司马0打下天下当了皇帝.他得知:朝廷中的一员将军是诸葛亮的后代,便想治治他.有一天,司马0找了个借口,把这个将军定了死罪.在金殿上,司马0问:“你祖父临死前说了些什么?”这个将军就一五一十地把诸葛亮的话说给他听.司马0听后,使命令上兵们把房子拆了,取出纸包.只见纸包里面有封信,上面写着“遇皇而开”.土兵们把信递给0,0打开信,只见里面写道:“访问后返三步.”0立即站起身退后三步.他刚站稳,只听“咔嚓嚓”一声响,0龙案上面正对的房顶上,一根玉掉下来.把桌椅砸得粉碎.0吓得出了一身冷汗.反过来再看信后面写道,“我救你一命,请你留我后代一命.”看完这封信,暗暗佩服诸葛亮的神机妙算.后来.他把那个将军官复原职 诸葛亮的八卦衣 在戏剧和图面中,诸葛亮都是身披八卦衣,运筹帷幄,决胜千里的姿态.据民间传说诸葛亮的八卦衣是他勤奋好学,师母所赏赐. 诸葛亮少年时代,从学于水镜先生司马徽,诸葛亮学习刻苦,勤于用脑,不但司马德操赏识,连司马的妻子对他也很器重,都喜欢这个勤奋好学,善于用脑子的少年.那时,还没有钟表,记时用日晷,遇到阴雨天没有太阳.时间就不好掌握了.为了记时,司马徽训练公鸡按时鸣叫,办法就是定时喂食.诸葛亮天资聪颖,司马先生讲的东西,他一听便会,不解求知饥渴.为了学到更多的东西,他想让先生把讲课的时间延长一些,但先生总是以鸡鸣叫为准,于是诸葛亮想:若把公鸡呜叫的时间延长,先生讲课的时间也就延长了.于是他上学时就带些粮食装在口袋里,估计鸡快叫的时候,就喂它一点粮食,鸡一吃饱就不叫了. 过了一些时候,司马先生感到奇怪,为什么鸡不按时叫了呢?经过细心观察,发现诸葛亮在鸡快叫时给鸡喂食.司马先生在上课时,就问学生,鸡为什么不按时叫鸣?其他学生都摸不着头脑.诸葛亮心里明白,可他是个诚实的人,就如实地把鸡快叫的时候喂食来延长老师授课时间的事如实报告了司马先生.司马先生很生气,当场就把他的书烧了,不让他继续读书了.诸葛亮求学心切,不能读书怎么得了,可又不能硬来,便去求司马夫人.司马夫听了请葛亮喂鸡求学遭罚之事深表同情,就向司马先生说情.司马先生说:“小小年纪.不在功课上用功夫,倒使心术欺蒙老师.这是心术不正,此人不可大就.”司马夫人反复替诸葛亮说情,说他小小年纪,虽使了点心眼,但总是为了多学点东西,并没有他图.司马先生听后觉得有理,便同意诸葛亮继续读书. 司马先生盛怒之下烧了诸葛亮的书,后经夫人劝解,又同意诸葛亮来继续读书.可没有书怎么读呢?夫人对司马先生说:“你有一千年神龟背壳,传说披在身上,能使人上知千年往事,下晓五百年未来.不妨让诸葛亮一试.如果灵验,要书作甚?”司马先生想到把书已烧了,也只好按夫人说的办. 诸葛亮将师母送的神龟背壳往身上一披,即成了他的终身服饰——八卦衣,昔日所学,历历在目,先生未讲之道,也能明白几分. 诸葛亮的鹅毛扇 诸葛亮的鹅毛扇代表着智慧和才干,所以在有关诸葛亮的戏曲中,孔明总是手拿鹅毛扇. 关于鹅毛扇,民间流传着这样的故事,黄承彦的千金小姐黄月英并非丑陋,而是一个非常聪明美丽、才华出众的姑娘.黄承彦怕有为的青年有眼不识荆山玉,故称千金为“阿丑”.阿丑黄月英不仅笔下滔滔,而且武艺超群,她曾就学于名师.艺成下山时,师傅赠送她鹅毛扇一把,上书“明”、“亮”二字.二字中还密密麻麻地藏着攻城略地、治国安邦的计策.并嘱咐她,姓名中有明亮二字者,即是你的如意郎君.后来黄承彦的乘龙快婿,就是吟啸待时、未出隆中便知天下三分的名字中有“明”、“亮”二字的未来蜀国丞相诸葛亮.结婚时,黄月英便将鹅毛扇作为礼物赠给诸葛亮.孔明对鹅毛扇爱如掌上明珠,形影不离.他这样作不仅表达了他们夫妻间真挚不渝的爱情,更主要的是熟练并运用扇上的谋略.所以不管春夏秋冬,总是手不离扇. 清朝康熙年间,襄阳观察使赵宏恩在《诸葛草庐诗》中写道:“扇摇战月三分鼎,石黯阴云八阵图”,就足以证明诸葛亮手执鹅毛扇的功用以及他手不离扇的原因.

解释下下面这段话的意思
Logarithms(对数) were invented to shorten the work of extended computations, which involve one or more of the operations of multiplication(乘),division(除),involution(乘方), and evolution(开方).their use has decreased the labour of computing to such an extent that many calculations ,which would require hours without the use of logarithms,can be performed with their aid in a small fraction of that time

对数的发明是为了减少扩展计算的工作量,它包括一次或者多次的乘法,除法,乘方,和开放的运算操作.对数的使用对计算量的可以减少如此地步,以至于许多计算工作在不使用对数的情况下,需要花费数个小时,也只能进行相关的一小部分运算.

显然,要使-a的六分之一次方有意义,必须-a>=0,即a=0
所以3 √(a) ·6√(-a)=-1×(-a)的三分之一次方×(-a的六分之一次方)=-√(-a).(就是负的根号-a,这个是不能再化简的)

the Salinity of Ocean Waters
If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. In this manner the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.
the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.
Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.
A third process by which salinity may be altered is associated with the formation and melting of sea ice. When sea water is frozen, the dissolved materials are left behind. In this manner, sea water directly materials are left behind. In this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.
In the Weddell Sea Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.
NOTE:
salinity / sэ'linэti; sэ`linэti/
n [U] the high salinity of sea water 海水的高含盐量.
--->>>saline / 'seilain; US -li:n; `selin/
1.adj [attrib 作定语] (fml 文) containing salt; salty 含盐的; 咸的:
* a saline lake 盐湖 * saline springs 盐泉
* saline solution, eg as used for gargling, storing contact lenses, etc 盐溶液(如用于漱喉、存放隐形眼镜等).

为了让你彻底明白,我分析得详细一点:
去掉一个最高分,平均分是9.25分
说明去掉最高分后,剩余6个分的平均分是9.25分
那么这6个分的总分是6×9.25=55.5分
即:最低分+中间5个分=55.5分.①
去掉一个最低分,平均分是9.31分
说明去掉最低分后,剩余6个分的平均分是9.31分
那么这6个分的总分是6×9.31=55.86分
即:最高分+中间5个分=55.86分.②
②-①得:最高分-最低分=55.86-55.5=0.36
∴最高分与最低分相差0.36分
总的算式是:6×9.31-6×9.25=0.36

1.
3X+4Y=16 =>x=(16-4y)/3.
代入
5X-6Y=33
可得:
5*(16-4y)/3-6y=33.
变形化简得:2y=-1.
所以,y=-1/2,x=6.
2.
4(X-Y-1)=3(1-Y)-2 4X-Y=5 =>Y=4X-5.
代入
X/2+Y/3=2得:
X/2+(4X-5)/3=2.
化简得:
11X=22.=>X=2.
所以,Y=3.
3.
3(X-1)=Y+5 Y=3X-8.1)
5(Y-1)=3(X+5) 5Y=3X+20.2)
将1)代入2)得:

a sample of 75 "property intensive" firms from seven singapore non-real estate industries was included in the study. for each firm, we estimated and compared four performance measures: medium return, standard deviation (a *** for total risk), time-varying systematic risk (beta) and time-varying jensen abnormal return index (7i) for the "composite" and "business" return series. the "composite" return series included the real estate impact on the equity market. the "business" return series was derived by removing the influence of the real estate market from the "composite" returns. we used the msci world equity index to *** for the "market". the results for both the nominal returns and inflation-adjusted returns are reported. there is some evidence of lower returns, higher risks, higher systematic risk and poorer abnormal return performance associated with cre asset ownership. additionally, the unfavorable (negative) stock market performance impact of cre appeared to be consistent for all the non-real estate firms in the seven industries and in different pai% portfolios. these conclusions hold for the two alternative cre performance benchmarks used, namely "pure" property stock market index and "pure" office market index.

本研究例举了来自新加坡非房地产行业的75个财团公司的案例.案例中的每一家公司,我们都将从四个表现纬度来评估比较:中期回报;标准偏差(代表所有风险);随时间变化的系统性风险(β)和詹森复合、商业回报异常指数.复合回报系列指数考虑了房地产业对资本市场的影响.而商业回报系列指数则是通过移除复合回报指数中房地产业的影响推导论证的.我们利用摩根斯坦利世界资本指数来代表“市场”,从而可以推导出名义回报和实际回报(考虑通货膨胀的因素).有证据显示CRE资产所有制会导致低回报、高风险、更高的系统风险和更低的异常回报.此外,股票市场的低迷和负面表现对CRE的影响似乎与之对来自七个行业的非房地产公司和不同PAI%组合的影响是一致的.这些结论适用于CRE的两种供选择表现的检测分析,即纯粹的地产股票市场指数和办公写字楼市场指数.

ABSTRACT By analyzing the process of hot water circulating and the implication of additional flow,the weakness,lying in the definition of additional flow and in the calculation formula of circulating-pump head and circulationg-pump flow in current code,is pointed out. The implication of additional flow is also discussed.A new opinion about calculationg the pump head and the pump flow is brought brought forward.
KEYWORDS circulating flow, additional flow, circulating-pump flow,circulating-pump head
1 Requirements of the code
In curent Code for Design of Building Water Supply and Drainage(GBJ15-88),there are mainly two stipulations to the circulating-pump in a central heating flow,the circulating-pump head should as 15% of the maximum hourly hot-water consumption;Secondly,the circulating-pump head should be counted as Hb=(1+qf/qx)2.hp+hx[formula?],in which Hb is the circulationg-pump head is the circulation flow;qf is the additional flow,hp and hx are the head loss in distributing pipes and in is the circulationg flow;qf is the additional flow,hp and hx are the head loss in distributing pipes and in returning pipes respectively. In the code,the additional flow is definged as follows: In a mechanical circulating hot-water flow should be considered when calculating the head loss in the distributing pipes, so as to prevent the circulation from being destroyed by the partial water consumption. This water flow is called as an additional flow.
In recent years, many queries focusing on the implication and calculation the additional flow are put forward,but this seemed to have taken no effect on the code. In this paper, these queries are to be discussed.
According to the code, the formula for calculating the circulating flow is :qx=(3600Qs)/(C.?t),where Qs is the heat loss,which can be counted as 5%to 10%of the hourly heat consumption;C is the specific heat of water;?t is the temperature difference. It‘s obvious that the circulating flow is figured out on the assumption that there is no consumption occurring in the hot water system, the purpose of circulating is to maintain the temperature of the system.

摘要:通过分析热水循环系统的过程和附加流的含义,指出了在附加流定义和循环泵水头以及流量计算公式在现行规范中的缺陷.也讨论了附加流的含义.提出了一个新的关于循环泵水头和流量的计算方法.
1 规范条件
供排水系统(GBJ15-88)设计现行规范中,关于循环泵中间暖水流量主要有两个限制,循环泵水头消耗15%最大每小时热水量;第二 循环泵水头可通过公式
Hb=(1+qf/qx)2.hp+hx计算,Hb是循环流量;fg是附加流,hp和hx是水头分管和回流时的损失.规范中附加流定义是:在机械循环中,当计算水头分管损失时,为了防止热水流循环被破坏,需要消耗部分水,这部分水这是附加流.
近年来,提出了许多关于附加流定义和计算的问题,然而规范对这些问题起不到作用.在本文中将会讨论这些问题.
根据规范,计算循环流量的公式是:qx=(3600Qs)/(C.t),其中Qs是热损失,可以以每小时热损耗的5%到10%计算;C是水的比热;?t是温差.很明显,计算循环流量是在假定热水系统不存在消耗的前提下的,循环的目的是维持温度系统.
注:中间有段英文重复了,个别句子读不通,像
In a mechanical circulating hot-water flow should be considered when calculating the head loss in the distributing pipes这句,是不是漏了标点符号?

Big Ben is one of London's best-known landmarks, and looks most spectacular at night when the clock faces are illuminated. You even know when parliament is in session, because a light shines above the clock face.
The four dials of the clock are 23 feet square, the minute hand is 14 feet long and the figures are 2 feet high. Minutely regulated with a stack of coins placed on the huge pendulum, Big Ben is an excellent timekeeper, which has rarely stopped.
The name Big Ben actually refers not to the clock-tower itself, but to the thirteen ton bell hung within. The bell was named after the first commissioner of works, Sir Benjamin Hall.
his bell came originally from the old Palace of Westminster, it was given to the Dean of St. Paul's by William III. Before returning to Westminster to hang in its present home, it was refashioned in Whitechapel in 1858. The BBC first broadcast the chimes on the 31st December 1923 - there is a microphone in the turret connected to Broadcasting House.
During the second world war in 1941, an incendiary bomb destroyed the Commons chamber of the Houses of Parliament, but the clock tower remained intact and Big Ben continued to keep time and strike away the hours, its unique sound was broadcast to the nation and around the world, a welcome reassurance of hope to all who heard it.
There are even cells within the clock tower where Members of Parliament can be imprisoned for a breach of parliamentary privilege, though this is rare; the last recorded case was in 1880.
The tower is not open to the general public, but those with a "special interest" may arrange a visit to the top of the Clock Tower through their local (UK) MP.

AB比较,铝离子和氧离子的电子数相同,但铝的质子数多,电子对离子半径有扩大作用,而质子则有收缩作用,所以铝比氧的小.同理硫比氟的大,比值最小.C选项,只相差一个电子,半径比更接近1,而且用上述法分析,电子数与质子数只差1,作用效果不明显.同理D中质子数只差一,也不明显,

这文章初中及以下读完不会有太多感触的.只要你把“珍惜阅读”这4个字弄清楚了,不读文章内容就知道大概什么意思了.
首先是阅读这个词,要搞清是个什嘛意思.它不只是有声的读书,无声的读人生,更进一步是说感受世间万物,沟通宇宙时间,阅读世间的一切一切.
貌似这文章全文都在说“阅读”这词,而且其中遣词用句很华美押韵.其实我感觉重要的是“珍惜”这个词.
因为“阅读”这个词和通常意义不太一样,所以作者用很大笔墨让人去笼统的感觉下“阅读”此词在此文中的含义,而重要的其实是“珍惜”这个形容词,这个定语.
珍惜这个词,在我看来,是作者经历了之前描写过的那么多阅读内容的感悟.因为“阅读”让人生幸福,所以“珍惜”是作者对幸福、对生命的一种感恩.就如稻香里所唱“珍惜 一切就算没有拥有”
全文手打,并纯粹个人观点,合适的话LZ要给高分~
