The first man to approach flying on a scientific basis was an Englishman who lived during the thirteenth century. 第一个真正意义上飞行的人是一个英国人，生活在13世纪。He looked at the air above us as a sea, and he believed that a balloon could float on the air just as a boat did on water. 他视我们头顶上的蓝天为海洋，并且他相信气球可以像船在水面上航行一样，在天空上飞行。Almost four hundred years later, an Italian priest applied his principle of air flight. 在近400年后，一位意大利的牧师应用了他的空中飞行的理论。He designed a boat, which would be held in the air by four hollow spheres. 他设计了一只船，可以由四个中空的气球带起。Each of the four balls was to be 20 feet in diameter and made of very thin copper. 每一个气球的直径都达到20英尺，用非常薄的铜片制成。But his boat was never built since it was not possible to make spheres of such thin metal and such size in those days.但他的船并没有做成，因为在当时根本不可能用如此薄的金属制造气球，也不可能造出如此尺寸的气球。

196560，详细见下：Kissing number problemEditWatch this pageIn geometry, a kissing number is defined as the number of non-overlapping unit spheres that can be arranged such that they each touch another given unit sphere. For a lattice packing the kissing number is the same for every sphere, but for an arbitrary sphere packing the kissing number may vary from one sphere to another. Other names for kissing number that have been used are Newton number (after the originator of the problem), andcontact number.In general, the kissing number problem seeks the maximum possible kissing number for n-dimensional spheres in (n + 1)-dimensionalEuclidean space. Ordinary spheres correspond to two-dimensional closed surfaces in three-dimensional space.Finding the kissing number when centers of spheres are confined to a line (the one-dimensional case) or a plane (two-dimensional case) is trivial. Proving a solution to the three-dimensional case, despite being easy to conceptualise and model in the physical world, eluded mathematicians until the mid-20th century.[1][2] Solutions in higher dimensions are considerably more challenging, and only a handful of cases have been solved exactly. For others investigations have determined upper and lower bounds, but not exact solutions.[3]

Notes on the text课文注释 1 The idea that… is mistaken. 此处that引导的从句作idea的同位语。 2 take no interest in…，作“对……不感兴趣”解。 3 cannot have failed to notice, 不至于没注意到。 “cannot+have+过去分词”表示对于过去的事所作的不肯定的推测。 4 move in response to a gust of wind，随风飘荡。 in response(to)作“回答"、“响应”、“作出反应”讲。此处是“（展品）随风而动”的意思。 5 be familiar to…是“为……所熟悉”的意思。 6 Lined up against the wall, 靠墙排列着。 7 like traffic lights which have gone mad, 就像失去控制的红绿灯一样。 go mad作“发疯”、“发狂”讲。 8 on and off（亦作 off and on）作“断断续续地”、“有时”讲。 9 These peculiar forms not only seemed designed…，其中seemed是系动词，seemed designed 作用与were designed是一样的。 参考译文 现代雕塑不再使我们感到惊讶了。那种认为现代艺术只能在博物馆里才能看到的观点是错误的。即使是对艺术不感兴趣的人也不会不注意到在公共场所展示的现代艺术品。公园里、大楼和商店外竖立着的奇形怪状的雕塑，对这些，我们已经司空见惯了。有些所谓的“现代”艺术品在那里已经陈列了近80年了。 尽管如此，最近举办的一次现代雕塑展览还是使一些人（包括我在内）大吃了一惊。走进展厅首先看到的是一张告示，上面写着：“切勿触摸展品，某些展品有危险！”展品都是些活动的雕塑。人们所熟悉的是悬挂在天花板上、造型奇特、随风飘荡的雕塑品。这些展品却使人大开眼界。靠墙排列着许多细长的电线，而电线又连着金属球。金属球经过磁化，互相之间不停地相互吸引或相互排斥。展厅中央是装有彩色灯泡的许多高高的构件，灯泡一刻不停地闪烁着，就像失去了控制的红绿灯。小黑盒子里迸出火花，红色灯泡发怒似地忽明忽暗。这儿倒像是在展览古老的电子设备。好像设计这些奇形怪状的展品不仅是为了给人感情上的强烈刺激，而且还想给人以电击似的！ Summary writing 摘要写作 In not more than 80 words describe what the writer saw from the moment he entered the art gallery.

溶解度氢化铝锂可溶于多种醚溶液中，不过，由于杂质的催化作用，氢化铝锂可能会自动分解，但是在四氢呋喃中表现得更稳定，因此虽然在四氢呋喃的溶解度较低，相比乙醚，四氢呋喃应该是更好的溶剂。 氢化铝锂在常温下是亚稳的。在长时间的贮存中，氢化铝锂会分解成Li3AlH6和LiH。这一过程可以通过钛、铁、钒等助催化元素来加速。当加热氢化铝锂时，其反应机理分为3步：3 LiAlH4 → Li3AlH6 + 2 Al + 3 H2 （R1）2 Li3AlH6 → 6 LiH + 2 Al + 3 H2 （R2）2 LiH + 2 Al → 2 LiAl +H2 （R3）R1通常以氢化铝锂的熔化开始，温度范围为150－170℃，接着立即分解为Li3AlH6，但是R1是在低于LiAlH4熔点的情况下进行的。在大约200℃时，Li3AlH6分解成LiH和Al（R2），接着在400℃以上分解成LiAl（R3）。反应R1在实际中是不可逆的，而R3是可逆反应，在500℃时的平衡压强是25千帕。在有适当催化剂的情况下，R1和R2反应可以在常温下发生。 LiAlH4遇水立即发生爆炸性的猛烈反应并放出氢气：LiAlH4 + 2H2O → LiAlO2 + 4H2LiAlH4 + 4H2O → LiOH +Al(OH)3+ 4H2由于放出的氢是定量的，该反应可用来测定样品中氢化铝锂的含量。为了防止反应过于剧烈，常加入一些二恶烷、乙二醇二甲醚或四氢呋喃作为稀释剂。这一反应提供了一个有用的实验室制取氢气的方法。长期暴露在空气中的样品通常会发白，因为样品已经吸收了足够的水分，生成了由氢氧化锂和氢氧化铝组成的白色混合物。 LiAlH4 的乙醚或四氢呋喃溶液能同氨猛烈作用放出氢气：2LiAlH4 + 5NH3 → [LiAlH(NH2)2]2NH+ 6H2当氨的量不足时，发生如下反应：LiAlH4 + 4NH3 → LiAl(NH2)4 + 2H2NH3/LiAlH4比值更小时，则氨中的三个氢都可被取代：LiAlH4 + NH3 → Li[Al(NH2)4] 氢化铝锂几乎可以与所有的卤化物反应生成相应的配位铝氢化物，当配位铝氢化物不稳定时，则分解为相应的氢化物。通式为：nLiAlH4 + MXn → M(AlH4)n + nLiXM(AlH4)n → MHn + nAlH3因此可通过此方法制备很多金属或非金属氢化物，如：2LiAlH4 +ZnI2u2212(u221240℃，乙醚)→ ZnH2 +2AlH3 + 2LiILiAlH4 + 4 NaCl → 4 NaH + LiCl + AlCl3 氢化铝锂可与NaH在四氢呋喃中进行复分解反应，高效的生产氢化铝钠（NaAlH4）：LiAlH4 + NaH → NaAlH4 + LiH氢化铝钾（KAlH4）可以用二乙二醇二甲醚作为溶剂，以类似的方式制取：LiAlH4 + KH → KAlH4 + LiH 氢化铝锂可将很多有机化合物还原，实际中常用其乙醚或四氢呋喃溶液。氢化铝锂的还原能力比相关的硼氢化钠更强大，因为Al-H键弱于B-H键。由于存储和使用不方便，工业上常用氢化铝锂的衍生物双(2-甲氧基乙氧基)氢化铝钠（红铝）作为还原剂，但在小规模的工业生产中还是会使用氢化铝锂。能被氢化铝锂还原的官能团主要包括：卤代烷被还原成烷烃。碘代烷反应最快，其次是溴代烷和氯代烷。此反应中一级卤代烷（伯卤代烷）性能较好，所得产物发生构型转化，因此认为该反应是SN2机理。二级卤代烷（仲卤代烷）也可用此法还原，三级卤代烃（叔卤代烷）容易发生消除反应，不适用此法。氢化铝锂只能用于还原醇基在附近的炔烃，不能用于还原简单烯烃和芳香烃。硅卤化物等还原为硅烷，如：LiAlH4 + SiCl4 → SiH4 + LiCl + AlCl3羰基化合物（酰胺除外）被还原为醇，如酯和羧酸都可以被氢化铝锂还原成伯醇。在氢化铝锂还原酯的方法发现之前，一般用布沃－布朗还原反应还原酯，即将煮沸的金属钠-无水醇作为还原剂，但这一反应较难进行。醛和酮也可以被氢化铝锂还原成醇，不过一般使用如NaBH4这类更温和的试剂来还原。α,β-不饱和酮会被还原成烯丙醇。环氧化合物。当环氧化合物被还原时，氢化铝锂试剂会攻击环氧化合物的位阻小的一端，通常会生成仲醇或叔醇。环氧环己烷会被优先还原成a键（直立键）的醇。酰胺和酰亚胺被还原成胺。这类反应一般产率较高，并且用N,N-取代的原料反应比其他要快很多。腈被还原成伯胺。另外，肟、硝基化合物以及烷基叠氮都可以被还原成胺。季铵阳离子可被还原成对应的叔胺。与醇反应生成烷氧基氢化铝锂：LiAlH4 + ROH → LiAl(OR)H3 + H2LiAlH4 + 2ROH → LiAl(OR)2H2 + 2H2LiAlH4 + 3ROH → LiAl(OR)3H + 3H2LiAl(OR)2H2 是将酰胺还原为醛的适宜试剂，LiAl(OC(CH3)3)3H是将酰氯还原为醛的适宜试剂，而利用氢化铝锂不能将酰氯部分还原生成对应的醛，因为氢化铝锂会将后者完全还原为伯醇，因此必须要使用更温和的三叔丁氧基氢化铝锂（LiAl(OC(CH3)3)3H）来还原酰氯。三叔丁氧基氢化铝锂与酰氯的反应比与醛的反应迅速得多，例如在异戊酸中加入氯化亚砜会生成异戊酰氯，这时可利用三叔丁氧基氢化铝锂将异戊酰氯还原为异戊醛，产率能达到65%。

　　“旅”是旅行，外出，是为了实现某一目的而在空间上从甲地到乙地的行进过程；“游”是外出游览、观光、娱乐，即为达到这些目的所作的旅行。旅游带的东西有哪些？一起来了解一下！ 　　 根据个人情况不同，也很难都说清楚，但是必须带的有： 　　1、护照 　　2、银行存款凭据 　　3、APS证书，或者德方学校明确通知，报到时必须携带和出示的其他证书原件。 　　4、小学至大学毕业的学历、高中以上成绩、学位、甚至工作证明等德国大学需要的公证件若干份(不多于8份，如果已经申请过学校了三五份即可)。 　　5、免冠正面彩色照片1寸两寸个若干(各30张足矣) 　　6、体检证明(国际健康证)。虽然大家反映出关几乎不会检查，以后作用也不大，可以不办。但是本人不能保证此物品出境时不必携带。请进ABCDV论坛搜索相关讨论。 　　 推荐带的电器： 　　1.计算机外设，例如鼠标，数据线，系统软件等 　　2.手机和电话 　　3.数码电器设备：数码相机 　　 不推荐带的电器： 　　1.热水壶，烧水壶 　　2.电脑 　　3.电饭锅等 　　 带什么东西 　　1. 旅行包/背包/行李箱:先说背包或行李箱。 　　背包一定要背起来舒服和适合自己的体型的。最好是可背、提两用和多袋兜，以便于物品分类的。我自助游时，通常背背包。最近，去欧洲时，却用有轮子的行李箱，也很好用。在欧洲，马路平坦宽阔，也有另设的行人路，交通设备方便，所以我拉着行李上下公共交通，和在市内行走都没问题。难得不用背着一个重重的背包。在那里我见到很多像我一样拉着有轮子行李的旅人，奇怪却很少见到背包客。 　　2.衣物（穿戴类） 　　：备换服装，备换鞋（最好是平跟鞋），比较紧的睡衣，领带围巾，帽子，手套，泳衣，短裤，生理用品，山区要准备一套稍微厚一些的外套 。还有比较紧的睡衣，卫生巾，首饰少带，钱也少带（现金少带，带一张信用卡），带些药（防虫的，止痒止血的，眼药水之类），再带足衣服，夏天无论如何带一件长袖衣 ；虽然你带的衣服取决于目的地的气候和你的旅行项目，但一般来说，一件轻便的雨衣是必须的，这件雨衣要有口袋、有帽兜。如果要带防风衣，就要带那种宽松的，里面可以加几件衣服的风衣； 　　3.洗漱用品 　　：最好不用宾馆旅店的洗漱用品，不太卫生，自备毛巾，牙具，化妆品，防晒水，太阳镜，饰品，洗浴用品，梳子；最好用小包装的洗发水和浴液，还有止水塞，旅行家都知道止水塞的重要作用，没有它你怎么能泡淋浴或在水池里积水洗衣服呢？平时止水塞能适用于各种洗涤池，另外还要带一包洗衣粉。包够大的话最好再带一个袖珍的电吹风（吹头发、急需干的湿衣服），作用不小哦。 　　4.重要证 件 　　– 护照、签证、身份证和驾驶执照、结婚证、介绍信。这不用多做解释，唯一想提，也提过的是，最好附带几份副本，以防遗失正本时用上。 　　5.现金和信用卡 　　- 必须换好一些小钞和硬币，以备买小物品或给小费。住酒店、上较高尚餐厅用餐的话，当然是以信用卡付钱，总之现金少带，首饰少带，以免钱财外露； 　　6.机票、火车票、旅店等各种已预定的交通和住宿证明和收据。 　　7.便携充气颈枕或充气腰靠一个，乘飞机、坐火车以及长途巴士时可以用到，可以很好的保护颈椎和腰部； 　　8.眼罩（可选比较可爱的卡通眼罩）、耳塞(ear plugs) – 尤其是不易入眠、住在青年旅舍多人间，或靠近繁忙马路的旅店的`朋友。 　　，在途中休息的时候可以用到，如果是在冬季或者多风沙的季节出行，还要别忘了带上口罩； 　　9.收纳袋若干，包括鞋袋鞋包、杂物收纳袋、卡包等等； 　　10.洗漱包也是必不可少的，可以将洗漱用品放在里面，另外准备一个牙刷盒，可以将牙刷和牙膏放在里面，既实用又卫生； 　　11.一本资料齐全的旅游指南- 就只一本哟！带太多书很重，除非是去好几个不同的国家。另外还有旅行日程表，地址电话通讯册； 　　12.医药包/急救包/小药盒以及一些药物 – 在安全和健康手记，已提过，如止痛药、晕车药、止泻药、感冒药、胶布、消毒水、防晒膏等。这里我再补充一点小经验，那就是请带一小块干净的姜片，当你突发急性肠炎，腹泻腹痛时，服用一小块姜，只需几分钟，一些OK。这可是本人几天前在郊外亲身再次尝试过的成功经验，胜过黄连素，挽救了一顿美味大餐。其实本人最讨厌吃姜了，可是我还要强烈建议我自己和您带上它吧。 　　13.旅游和医药保险单和其热线电话。也需备有副本。还有就是你国 籍在目的地的大使馆地址和电话号码。 　　14.目的地详细地图和交通设备地图 　　15.指南针 – 这个很重要。有了地图，却看不出方向，还是没用。尤其在比较落后的国家，很多路标不完整、不清楚，甚至错误的。有个指南针绝对较少迷路的次数。 　　16.手机/手提电话 – 我想，现代人已到了一种没手机就无法过日子的时代。我不提大家，我想大家还是会带的。更重要的是，这也是个和外界或家人联系有效的渠道。唯，出国前，要向手机公司询问，你到的目的地是否也可搭上线。一般情况下，现在 的全球通手机完全可以保证全球通。如不可，到了目的地可买一张短期或“pay as you go”的手机卡。 　　(现在的手机大部分是世界通用的)。我去国外，通常都会买一张手机卡，因为比较便宜和划算。最重要的是，记得通知家人你在国外的手机号码。请记住，为自己保留一条与外界联系的有效渠道，是身处困境时最后的法宝。这一点即使在境外旅游也是如此。建议不要拿手机当表用，因为旅行时最爱丢的东西就是手机。只要不需要通话，就保存在最安全的地方，晚上入睡前，务必关掉手机，节省电能。按这种方法，一般一块厚锂电池可以坚持整四天的旅游行程。 　　17.手表和小闹钟 – 虽说手机有时间和闹钟的功用。我通常还是会带手表和闹钟的。在路上，把手机拿进拿出地看时间有点显眼，容易引起小偷的注意，也容易遗失。手表在手腕上方便多了。晚上睡觉，我也不喜欢整晚开着手机以当闹钟，手机要常充电很麻烦。商务通、文曲星：时间是保证行程是否顺利的关键，商务通和文曲星上不但有时间有闹铃，而且还有很多有助于旅行的内容。 　　18.手电筒 – 我和Ed有的是可带在头上的小灯。不知中文叫什么，英文是headband light。也很实用。要那种轻便防水、防挤压，聚光好，电珠耐用的电筒，买最好的高容量电池（起码是2号电池）。千万不要吝惜钱，用旧电池。 　　19.少量干粮 - 巧克力、饼干等的。有户外活动的朋友，一定明白干粮的重要性。即使是在城市行走，一时迷路或错失交通，气候转变而卡在一处等，包包里有些干粮可帮助解饥寒。 　　20.通用转换插头 – 每个国家的插头插座的标准都不尽相同。带了需要的电器却发现无法使用是很恼人的事，在外地要买也麻烦。最好备有一个世界通用的转换插头。 　　21.(通用) 充电器 – 带了相机、手机、MP3 Player, 却发现忘了带充电器，我一定会发疯！哈哈！所以，一定要记得带各个充电器。听说市场上有一种是通用的，所以不用带上多个不同的充电器，一个就行。我是听说，还没用过。精通电器的朋友，你们觉得呢？ 　　22.一个实用的日用包包 – 一个可装得下水瓶、一些干粮、旅游指南、地图、小笔记本、笔，甚至雨伞、帽子、防晒膏(如果烈日)、手套围巾(如果天冷)等的日用包包。 　　23.其他小用具：相机，胶卷，随身听，刮胡刀，计算器，电池，指甲刀，开罐器，小型电热杯，小型衣架，针线包，吹风机，纸笔，money belt 和小锁头- 尤其是去扒手多或不太安全的国家。当然还有纸巾，千万不要忘了哦； 　　24.饮食:几块巧克力：旅游地区往往风云莫测，一旦陷入阴冷潮湿，山风凛凛，饥寒交迫的处境，几块巧克力是坚持下去的顶梁柱，本人曾身有体会。最好再备上几块牛肉干，这样可以延长抵抗饥饿的时间，从而振奋起精神。

1维数组叫矢量，2维数组叫矩阵，3维及大于3维的数组就叫多维数组了。你这就是多维0数组。

还可以用牛奶，豆浆。还可以用盐水，干了以后，用铅笔涂

糖水不等式的证明可以从以下几个方面来看：1、从生活常识理解小文有一杯糖水，（重a克，里面有b克的糖，这份糖水的浓度就是糖/糖水=b/a。） 小文跟妈妈说，这糖水太淡了，不够甜，妈妈拿出了c克白糖，放进了小文的杯子里。（现在糖水重 a+c，里面的糖为b+c，浓度变为（b+c）/(a+c)） 小文拿起杯子一尝，果然比原来甜了。就这么一个简单的场景，其实就得出了这个糖水不等式。 原来的浓度：b/a < 加糖后的浓度 （b+c）/(a+c)。当然，结论还可以推广一下，譬如用淡的糖水+浓的糖水得到甜度中等的糖水。2、从斜率理解。b/a 是浓度，也代表点（a，b）与原点连线的斜率，因为限定b<a（最甜就是纯糖了，浓度100%），所以直线一定在y=x下面（第一象限）。随便举个例子，B（5，1）点的横坐标，纵坐标都加上5，得到 d（10，6），很明显DO的斜率大于原来BO的斜率，即浓度变大。3、应用千万不要小看这个简单的糖水不等式，在高中的不等式证明的时候巧妙应用糖水不等式，可以实现不等式的缩放，将证明极大简化。不等式的缩放是一种艺术。

鸡蛋可以在糖水中浮起来。鸡蛋可以在糖水中浮起来，水中加白糖鸡蛋会浮起来，这是因为在水中加入了白糖之后，糖水的浓度会上升，所导致的结果就是鸡蛋会自然的浮上来，这个原理跟往水中加盐的道理是一样的。当鸡蛋在水中的介质密度越大，它所受到的浮力也就越大。鸡蛋的早期发育过程1、鸡属卵生动物，胚胎在卵中发育。受精后，合子在输卵管中要经过24～27小时的发育。在如此长的时间内，合子已发育到了囊胚阶段甚至原肠胚早期阶段。此时在卵黄上可见略大白色圆盘称为胚盘，其中包含了成百上千个细胞，因此这时的鸡蛋，已不再是一个细胞了。2、产蛋母鸡如果没有接受雄鸡交配，其所产蛋的卵子停留在减数第二次分裂的中期，因此，这样的每枚鸡蛋（严格地说是蛋黄）可以看成一个很大的细胞。

糖水桔子罐头的保藏原理：1、糖分高，使得微生物不能生存。2、密封无氧，有氧微生物无法生存。水果罐头的存储注意事项：第一，不要贮存太久虽然水果罐头的贮存期很长，但也有一定的期限，所以若贮存太久，水果罐头发生变质，如长毛变色，就不要食用，以免发生食物中毒。第二，水果罐头要存放在干燥、阴凉、通风处罐头放在潮湿、闷热的地方，容易生锈且影响质量和贮存寿命；若放在阳光时常照射的地方，水果罐头本身容易起变化；因此要选择干燥、阴凉、通风的地方。第三，要注意生产日期把生产日期接近的水果罐头，放在相近的位置，且日期愈久的要先吃，尽快食用为宜。第四，不必冰在冰箱中水果罐头制作时经过杀菌的步骤，所以不必摆进冰箱，若冰箱中有多余的空间来摆置罐头，则更可延长其贮存寿命。但如饮料、水果罐头为了风味可冰在冰箱中，则更清凉可口。
