埃及人应该如何正确开发、利用、保护她们的母亲河

④公元前5000年

1螺旋式建造法,就是沿四面墙壁建成螺旋式的阶梯状,一边上楼梯,一边往上盖.2埃及人当时是用铜或青铜的凿子在岩石上打上眼,然后插进木楔,灌上水,当木楔子被水泡胀时,岩石便被胀裂.这样的方法在今天看来也许很笨拙,但在4000多年前,却是很了不起的技术.3建造金字塔的巨石不是天然的,而是人工浇筑的.从一位考古学家那里,得到5块从埃及胡夫金字塔上取下的小石块,对它们逐个加以化验.出乎意料的是,化验结果证明,这些石块由贝壳石灰石组成.尽管考古证明,人类在几千年前就已掌握混凝土制作技术,但这些贝壳石灰石浇筑得如此坚如磐石,以至很难将它们与花岗岩区别开来,实在使人难以相信.由此推测,当时古埃及人建造金字塔是采用“化整为零”的办法,即将搅拌好的混凝土装进筐子,抬上或背上正在建造中的金字塔.这样,只要掌握一定的技术,就能浇筑出一块一块的巨石,将塔一层一层加高,这种做法既“省力”又省工,据他估计,当时在工地上劳动的人仅有1500人,而不是象希罗多德所说的那样每批都有10万人.更出乎意料之外的是,法国科学家还在石块中发现了一缕一英寸长的人头发.这缕头发可能就是他们辛勤劳动和灿烂智慧的见证.但上述这些说法都还是一些推测.但无论如何,修建金字塔,一定是集中了当时古代埃及人的所有聪明才智,因为它需要解决的难题肯定是很多的.但是这些问题都解决了,金字塔修起来了,而且屹立了4000多年,这本身就是一大奇迹.所以,可以说,金字塔是古代埃及人民智慧的结晶,是古代埃及文明的象征.有的人不相信依靠简单的协作也可以创造出奇迹,不相信地球上的人类自身会创造出金字塔这样的奇迹,把它说成是天外来客的创造.这显然是不正确的,这无助于人们探索自己的历史,认识自己的能力.

Egyptian 古埃及人说的语言.

一代又一代的法老消逝在历史的尘埃之中,谁也没能永恒.只有金字塔,历尽数千年风雨沧桑而岿然不动.它们曾经光洁的表皮,已随沙漠的风沙剥蚀殆尽,像一个个苍凉的老人,无言地嘲弄那些自欺欺人的法老们,并以身示范,阐释着人类文明起步的艰难,引领我们去观看东方艺术与美学源头的无限风光.尼罗的四季,四季的太阳,和永远不变的金字塔,构成一幅永远流动的画面.

是一种象征符号
埃及人崇拜太阳,当太阳透过云层照下来时可以看到由光束勾勒出类似金字塔的形状.
人害怕时间、时间害怕金字塔,金字塔是人类对生命及永生的膜拜的符号.
另类考古学谈到金字塔内虽然有类似石棺的石槽,但并未找到其他相关线索.塔内找到的唯一的法老胡夫雕像也不是古王国时期的,所以不能说他就是陵墓.更有学者认为它是上一个人类文明用来发电的设施,当时金字塔周围有河道.

B苏美人
楔形文字是苏美尔文明发明的：
楔形文字也叫“钉头文字”或“箭头字”.古代西亚所用文字.多刻写在石头和泥版（泥砖）上.笔画成楔状,颇像钉头或箭头.约公元前3000年左右由两河流域苏美尔人所创造.阿卡得人、巴比伦人、亚述人、赫梯人、波斯人等,都曾使用这种文字书写自己的语言.也是各古国间交换外交文书的通用文字.考古学家发现大批各种楔形文字泥版或铭刻,19世纪以来被陆续译解,从而形成一门研究古史的新学科——亚述学.
幼发拉底河和底格里斯河都发源于亚洲西部的亚美尼亚高原.公元前4000年左右,这里就有了最早的居民——苏美尔人.他们创造了灿烂的苏美尔文明,最能反映这种文明特征的是他们的文字——楔形文字.

在埃及这块土地上的民族是有阿拉伯人、希腊人、罗马人还有一些土著的埃及人,但是他们已经没有了自己的语言,都讲着阿拉伯语的这样一个世界混杂的民族了

解题思路：（1）由反应信息可知，B（CH₃）₃分子中的一个B-C键断裂，Br原子取代甲基，甲基与H原子结合生成甲烷，故B（CH₃）₃和HBr反应生成其二溴代物为B（CH₃）Br₂，1molB（CH₃）₃发生二溴取代同时生成2mol甲烷；
（2）根据n=[m/M]计算5.6g B（CH₃）₃和9.72g HBr的物质的量，假设生成的B（CH₃）₂Br为xmol，生成B（CH₃）Br₂为ymol，结合B原子及溴原子守恒列方程计算．

The origin of the ancient world perfume
Egypt
Around the third millennium BC, Egypt began to use spices, which is much earlier than the Egyptian civilization others. Egyptians invention may Philippine incense is the earliest human perfume, but was not yet that high-purity alcohol refining technology, so accurate, it should be said that this perfume called sesame oil, specifically by priests and pharaohs made.
Persia
In ancient Persia, perfume symbolizes the identity and status. In the palace, the emperor must be the most fragrant one.
Greece
Greeks deified perfume, considered gods invented perfume, smell the fragrance represents the coming of the gods and blessing.
Rome
More affluent Romans pursuit of luxury atmosphere, they like perfume on the floor and walls, like to give their pets the horse and pet dog wear perfume, perfume banner army to triumph.
Italy
After the 15th century, perfume is widely used, and start using the thick tallow spices. Such fads soon spread to France, Britain and other European countries. Seventeenth century, Paul Feminis prepare a kind of wonderful fragrant smell of the liquid, because he was living in Cologne, Germany, hence the name "cologne." Later, hobbies clothing and cosmetics on the special love of French perfume, perfume went on to become a high fashion ladies hands essential supplies.
France
Since the latter half of the nineteenth century, perfume manufacturing technology is relatively mature, the early volatile solvent distillation is replaced by heat is not born in France of synthetic fragrances, perfumes are no longer limited natural flavor, which makes the perfume industry quickly development. As Frenchman was like leather gloves plus fragrances, and the best is to go looking for this glove Grasse (Grasse), this French city also gradually prosper because of this trade, and its perfume industry has been very good development, the French will soon have the world's perfume capital of the title.


⒈ ambergris
For a long time no one knows its origin, in fact, that it was from a sperm whale eating a squid after discharge, a round floating in the tropical sea and the waves washed over the beach, shapes and sizes. Dry before use at least blowing three years.

⒉ musk
Himalayan musk deer from the male body extract granular crystals thylakoid about walnut size, the extraction process without killing musk deer. This is all spice varieties, the most intense flavor, you can drop the handkerchief fragrant 40 years.

⒊ civet
From the tail of a cat incense inside thylakoid extract secretions, looks a bit like butter, Ethiopia, Myanmar and Thailand have this civet produced.
⒋ castoreum
Sacs from inside beaver extract of a red-brown creamy discharge. From the 9th century AD, since someone with the earliest users of the Arabs.

根据一项新的研究,建造金字塔的古埃及人可能是将拉动重物的滑橇前方的沙地湿润,从而能够移动巨大的石块穿过沙漠.




吉萨金字塔,公元前2589年~公元前2504年间建造

阿姆斯特丹大学的物理学家们研究了在沙漠沙地上拉动承载重物的巨大滑橇所需的力,发现将滑橇前方的沙子弄潮湿会降低滑橇上的摩擦力,从而使滑橇更容易操作.这个发现有助于回答最持久的历史谜题之一：古埃及人如何能够完成那项看起来不可能完成的任务——建造起著名的金字塔.

做出这项发现,研究人员是从古埃及人自身上找到了线索.一幅在杰胡提霍特普（Djehutihotep）陵墓墙壁上的浮雕（时间大约在公元前1900年）,描绘了172个人使用绑系在滑橇上的绞绳牵拉一个巨型雕像.在这幅图中,能够看到有一个人站在滑橇的前端,往沙地上倒水.

“埃及学家们认为这是一个纯粹的仪式动作,问题是,他们为什么这么做?”这项研究的第一作者Daniel Bonn说.




在沙盒上拉动重物,左侧干沙子,右侧湿沙子

Bonn和他的同事们建造了缩小的滑橇,并且在沙盒中拉动重物做试验.（如上图）

当研究人员在干燥的沙子上拉动滑橇,他们发现沙堆会在滑橇前方堆积,需要更大的力才能拉动滑橇前进.

然而,向沙子里添加水分,增加了沙地的硬度,滑橇能够更容易地在表面上滑行.这是因为,水滴在沙粒之间建起了桥梁连接,这能够帮助沙粒粘合在一起.也是由于这个同样的原因,使用湿沙子建造沙塔会比使用干沙子容易.

“这说明将埃及的沙漠湿润能够显著的降低摩擦力,结果显示,对比干燥的沙地,在湿润沙地上拉动滑橇只需要一半的人力.”Bonn说.

都是些高中就学过的简单原理,无非是滚动,杠杆,滑轮,物理不重要,重要的是古埃及人民辛勤的汗水早就了金字塔的辉煌

1 从人口分布方面分析：人口主要集中在尼罗河两岸
2 从农业生产和分布方面来分析 ：尼罗河定期泛滥给两岸带来肥沃的土壤,故而埃及人赖以生存的农业仰仗尼罗河,土地当然集中在两岸.
3 从城市分布方面来分析 :埃及沙漠面积广大,气候干燥,人口多的城市自然和水密不可分,城市的建立依托尼罗河了.
4 从旅游资源方面来分析 ：由于埃及历代帝王建都都在尼罗河附近,因而有旅游价值的文物古迹遗址应该主要在尼罗河流域.
5、结论是：没有尼罗河就没有埃及.埃及是尼罗河的赠礼
