阐述产生圆偏振光和椭圆偏振光的原理---

作者:宋应星. 明朝末年.今江西奉新人.宇宙天地容纳万物,而事之纷繁复杂便由此衍生.物.事遵循相同的规律,互相影响派生出世界万相而无所遗缺.这难道是人力可比的吗? 《天工开物》中的这段话闪耀着朴素的唯物主义思想的...

月全食阶段月球完全位于地球本影内,太阳的照射还在,只是由于地球的遮挡,阳光无法直接照到月球表面.
但地球表面有浓厚大气层,这时地球大气还会把一部分光折射到月球表面.在可见光中,红光的波长较长,蓝光和紫光的波长较短,空气中的尘埃和颗粒对波长较短的光有明显的散射作用,蓝紫光被散射掉,所以最终经过大气折射到月面上的主要是红光.

为阐述拿来主义作铺垫,用以反比

组合起来就像一个屋顶，人就是在精神小屋的庇护下栖居的，人是需要面对繁杂生活的淡定的；
组合起来就是一双翅膀，人就是在羽翼驾驭中前行的，人是需要追逐梦想的执着的。

你提到惯性指数, 那么A是某个二次型的矩阵
线性代数一般讨论实二次型, 那么A是实对称矩阵矩阵
实对称矩阵总可正交相似对角化
即存在正交矩阵P,满足 P^-1AP = P^TAP = diag(a1,...,an)
-- 这里 a1,...,an 是A的特征值
对应的二次型的标准形即 a1y1^2+...+anyn^2
所以A的正特征值的个数就是正惯性指数, 负特征值的个数就是负惯性指数

那百花齐放的春,我不爱它,它太娇艳；那生机勃勃的夏,我不依恋它,它太泼辣；那银装素裹的冬,我也不喜欢它,它太冷漠.惟独那秋,那落叶纷纷的秋,才是我的至爱
每当夏天带着人们的烦躁走了,秋天便又迈着轻盈的步伐向我们走来.她吸引我的不是丰收的喜悦,而是那一片片悄然无声落下的树叶.秋妈妈为耐寒的广玉兰叶片带来了一件毛茸茸的黄褐色的“披风”；为修长的柳叶带来了一件黄色的“运动衫”；为落落大方的枫叶姑娘带来了一套火红的“连衣裙”.
我漫步于树林中,寻找着“秋”给人世间带来的“礼物”.
我走着走着,无意间抬头一看：一棵粗壮的银杏树,叶子已经枯黄.前面还有几只黄蝶在追逐嬉戏,慢悠悠地飘向大地.我伸出双手接住了它.呦,原来是银杏树的孩子-----银杏叶.它长得像一把扇子,原本翠绿的叶边已经开始泛黄,深黄的叶脉连着叶柄.我轻轻地对它吹了口气,它便顺着我的手滑落了下去,回到了真正属于它的地方-----大地母亲的怀抱.
我继续向前走,脚底踩着厚厚的叶片,发出“咔嚓-----咔嚓”得清脆的响声,踩在树叶上软绵绵,舒服极了.有一种“逝如秋叶之静美”,“不是春光,胜似春光”的感觉.
正当我陶醉其中时,不远处地上的一片火红的艳丽的枫叶勾起了我的兴趣.
于是,我便轻轻地走过去把它捡起来,捧在手中,细细地端详.经过秋霜的打击,叶子的颜色用语言难以表达,深红,暗红,似红非红,似绿非绿,红中夹杂着绿,绿中又 透着红,总而言之,它包含了各种层次的红和绿,虽然颜色很多,但秋姑娘却把它 调汇得异常融恰,真是多一分则太艳,少一分则太淡,这是任何一位画家都难以做到的.枫叶像一个小巴掌似的,每一个 手指的周围都长满了锯齿.叶子的末端很红也很尖,好像一旦刺破那儿,叶子中的红 就会流出来似的.它的叶脉很清晰,从叶柄向叶间延伸,像一幅有趣的画.我凑近闻 闻,嘿,叶子的芳香中还掺杂着泥土的芬.向远处望去,是一片枫树林!看到这种景象,我不禁想起唐代诗人杜牧的诗句“停车坐爱枫林晚,霜叶红于二月花”.
秋风瑟瑟,在我眼前出现了一幅“秋风扫落叶”的景象.被卷起的树叶像大海中的波涛,层层叠叠,连绵起伏.
我在“沙沙”的风声中矗立了一会儿.不由自主地张开双臂,闭上眼睛,感受大自然的温暖,呼吸大自然的气息.心中升腾起一种怪怪的但又十分美妙的情感.
渐渐地,渐渐地,我似乎明白了什么.
“落叶不是无情物,化作春泥更护花”.在瑟瑟的秋风中,落叶簌簌地飘洒到大地上.夕阳,轻轻地为它们抹上一层金黄的色彩；细雨,缓缓地为它们做最后一次洗礼.于是,它们离开了相伴了一个春夏的树干.难道它们就不再依恋秋天的树枝?难道它们就喜欢孤独的飘零?不,不是的.它们落下来,化为灰土,埋进泥尘里.其实,它们正是在自己的衰亡中,感觉到了来自大地的生命力,感觉到了来年春天的气息.它们之所以没有一点哀愁,不感到丝毫的悲凉,是因为它们深深懂得奉献给人的将是绿的生命,绿的海洋,绿的希望.毕竟,它们装点过春的美丽,它们赠予过夏的浓荫.
我爱秋天,更爱秋天的落叶

职业目标是什么? - What is the goal of your career?
I have set many goals for my career. My ultimate goal is to become a chief executive officer, but I realise that I have lots of things to learn before that. I think that the next logical step for me would be to become a division manager. It will teach me leadership skills and a lot of other skills which I can use to better benefit your company and myself.
未来几年的规划? - What are your plans for the next few years?
In the next couple of years, I plan to enter a good university – preferably in USA, Britain or something English speaking environment. This is because English is becoming increasingly important following globalisation and I must improve my language skills in order to meet the demands of the future labour market. I plan to put in a lot of effort into my studies at my university; and also, I plan to make a lot of friends (after all, no man’s an island).When I graduate, I will return to my home country and serve her with what I have learnt.
有什么优点（细心,努力工作,耐性,合作能力方面分别阐述）- What are the positive things about yourself?
I have a lot of positive attributes to myself. The first and foremost is my ability to corporate with others. I believe myself a good team member and a nice person to work with. I hope that this will further increase the efficiency of work in this company. Secondly, I am a hard worker. I have learnt this while I was in school – our teacher gave us a lot of work each day to train our endurance and will at hard work. And I must say that her efforts were not in vain. Lastly, I flatter myself at having a meticulous personality. I like to be organised and neat. And I believe that this is a very important skill that one must possess in the workplace.
为什么要选择这个工作? – Why did you choose this job?
After a careful self-analysis, I have arrived at the conclusion that I can do this job well and that this job is what I need. Firstly, I have all the qualifications this job requires. And I believe that I possess the skills that can make me do this job well: such as neatness, corporation and leadership skills. Secondly, I think that this job is what I have always wanted as a starting point of my life-long career. It is in the industry I am interested in and I believe that doing the job will teach me many valuable things.
对世博的感觉如何?- What do you think about the World Exposition?
The Expo in Shanghai is an internationally renowned event. Although I have not had the opportunity to visit it myself, I have read from the newspaper and heard from my friends that it is really an exciting and interesting event. I have heard that you can see all sorts of interesting things from all parts of the world including ancient Mayan arts and circus from Canada. I have also learnt that it is a low-carbon Expo; this increases my esteem for the organisers as they are concerned about our environment.
有什么爱好?- What are your hobbies?
I have many hobbies. For example, my favourite thing to do is to read novels. I read basically every written story – from the plays of Shakespeare to Harry Potter. I also like to play in ball games, whether it is tennis, volleyball or basketball. And my other hobby might sound a little unconventional – I like to volunteer at the local library as a book organiser. Perhaps it is because I like the calm environment in the local library; and that I can be the first person to know about the new books.
哇,好辛苦.如果满意的话,楼主请记得给分哦.

Visiting the museum should be one of the best choices for the tourists who have never been in the place before with a limited amount of time. The amazing experience would definitely make your precious time most valuable.
On the top of that, nothing could be as fascinating as the exhibition of the museum, which combines the visual entertainment, the educational experience and cultural sense altogether so well. The items on display are often organized by professional elaborately, designed not to confuse the spectators but to provide them with well-arranged knowledge. One who only read about the lives conditions of the creatures in Mesozoic can never imagine the breath-taking sight which could only be seen when he walks through the gallery of the fossils of dinosaur. Similarly, a thematic attire exhibit could impart the visitor about the convention of religion, custom and even ideology of a specified period, which are merely abstract impressions in reading material.
Meanwhile, the architecture designs, which are more often than not among the most idiosyncratic in the city, are worth the visit. For example, the famous Louvre, originated in 13th century, taking up the Renaissance style and undergoing the turbulence of French Great Revolution, accommodating with the ideas of the first grade contemporary architects, assume an not only unique but also gorgeous fashion that can be seen nowhere else, with the labyrinth-like structure and the wonderful masterpieces, overwhelming the visitors. The Palace Museum itself is the most well-preserved and grandest ancient China architectural complex. The symmetrical distribution of the buildings sufficiently reflects the philosophy of the Chinese architecture and the strict hierarchy ideas of ancient China.
Finally, some of the collections of a famous museum are second to no other celebrated resort locale. They are another kind of wonder on the earth, which demonstrate the superlative ingenuity and exorbitant crafts of human being. Few can hold there extolment to himself while they are visiting the Vatican Museum and dwarfed by the masterpieces of the Renaissance genius, namely, Rafael and Michelangelo, who had both devoted ten years of their golden era to the museum and sprinkled their talent in the countless paintings and statuary which have now been a part of the museum itself. Admiring such a artistic work only is a great mind-tugging that can be experienced right there, right then.

这首诗歌中的“往事”、“故国”、“雕栏玉砌”、“朱颜”都是具体所指,属于实写.“春花”、“秋月”、“东风”等是虚写,并且“春花秋月”、“东风”在诗中已被感情化,作者把虚实两者结合起来,使“愁”字跃然纸上,使读者头脑中勾画出一幅画：一位亡国之君,在一个洒满月亮那彻骨清辉的夜晚,凭栏眺望故都.心中不禁升起对往昔繁荣生活的怀念,对现在沦为阶下囚的痛心和忧愁.
特别是最后一句,作者把愁比作一江春水,把不实的愁绪形容的淋漓尽致.正所谓“真境逼而神境生”,由一江春风而产生的神境带给读者无限想象,愁到底是什么,作者有多少愁……
因此“愁”也在不断的联想中得到升华.使读者感受到的不仅是李煜的亡国之愁,更是对自己经有过的繁荣的理想和破败的现实,经过蹉跌和磨难之后仍无法成功而发出的慷慨,及对生活经过物是人非变化后的思索和发现.

解题思路：解答此题要知道：
（1）不同的物质在相互接触时，彼此进入对方的现象叫做扩散，这一现象说明一切物体的分子都在不停地做无规则运动．
（2）气压与沸点的关系，气压越高，沸点越高；气压越低，沸点越低．
（3）杠杆平衡条件是：动力×动力臂=阻力×阻力臂．
（4）上端开口，底部连通的容器都属于连通器．

A、“八月桂花遍地香”，这是因为分子在永不停息地做无规则运动，属于分子的运动，故该选项正确，不符合题意；
B、高山上煮饭，不容易煮熟，是因为高山上大气压低导致水的沸点低，故该选项错误，符合题意；
C、杠杆平衡条件是：动力×动力臂=阻力×阻力臂，故该选项正确，不符合题意；
D、船闸是利用连通器原理来工作的，故该选项正确，不符合题意．
故选B．

点评：
本题考点： 扩散现象；沸点及沸点与气压的关系；杠杆的平衡条件；连通器原理．

考点点评： 本题是一道综合了多个物理知识点的题目，做题时要对照相关的物理知识，仔细分析每一种情况的对错，注意物理与生活的联系．

在开始接受电磁波原理的时候（也就是光波）,我好奇地问老师,是不是电流发生变化的时候,周围就会产生磁场.老师回答说是的；于是我又问,那是不是很远很远的地方也有磁场,只是场很小.老师回答说是的；接着我再问,那电流一发生变化,很远很远的地方就有磁场,那为什么它的速度是不是
呢.老师严厉地回答,不对,任何速度都不能超过光速.
这个问题一直苦恼了我很久,直到学了相对论.
打个比方,AB两地相距
,但一个人在A地的人想去B地去旅游有没有可能呢?答案是完全有可能的,虽然人的寿命是有限的,虽然速度也不能超过C.但如果人的速度足够快,在高速运动中的人会发现AB两地的距离缩短.（极限状态分析：当他达到光速后,他会发现AB两地距离缩为一个点,AB两地在同一个位置,他可以瞬间从A点到达B点）在他在B点停下之后,他才发现,原来他只花了很短的时间就从A点到达了B点,就如同
一样,而光速那样的运动就像是自己的速度
,可以瞬间到达宇宙中的任何一个地方.
但有趣的是光速是永远不变的,变的只是运动中的
看静止的物体变短了,距离是变的
静止的
看运动中的物体时间变慢了,时间是变的
光速其实就是一个极限数字,他在速度领域就相当于数学领域的
.
这也解释了为什么光速在任何一个
下都是光速,不满足速度
；就好像数学中一个无穷大的数加上任何一个数值仍是无穷大.
所以
就像数学中出现一个比无穷大还要大的数一样,是不可能的
但这并不意味着人们观察不到
现象,在很多实验室里,特别是天文学,都可以观察到超光速现象,但这只是一种视觉假相,观察到的速度并不等于它的实际速度

这是不是要看课本啊?

“小树”,从破壳而出,到浓荫如盖,到枯萎凋零,都喻示着：生命由生长到衰亡的普遍规律,即“生命就是个过程”这样一个基本意义.两个寓意相似喻像的描摹,笔致相似,前后呼应,造成情感的复沓.

斯科特等人之所以没有去拉住奥茨,是因为奥茨实在活得太痛苦了.奥茨的脚趾已经冻掉,只能用脚板走路了,而且又是走一步摔一步的.为此,他已作好了自杀的准备——向威尔逊要了十片吗啡,欲留在睡袋里把自己的命运和朋友们的分开来.但是朋友们真诚地阻止了他,他只得用冻伤了的双腿踉踉跄跄地又走了若干公里－－－所以,我认为是朋友们看他活得太痛苦了,才下了狠心让他早点儿欢乐地死去.
奥茨的死是一种光荣的死.这样不仅不会再拖累他的伙伴了,还可以节约极其珍贵的燃料和食物以给他的伙伴们创造更多生的希望.大家也是为了成全他的心愿.

So tired, you will be.
Good luck.

请根据下列材料中关于矛盾的论述回答问题.
材料1：列宁指出：“就本来的意义说,辩证法是研究对象的本质自身中的矛盾.”“是实际生活中的实际矛盾,即辩证的矛盾,而不是字面上的、臆造出来的矛盾.”
材料2：杜林说：“矛盾的东西是一个范畴.这个范畴只能归属于思想组合,而不能归属于现实.”
材料3：艾耶尔断言：“自然界不可能有矛盾,只是在陈述中才可能有矛盾.”
请回答,在矛盾存在问题上
1、材料1的观点是什么?是否正确?
2、对比材料1与材料2,指出材料2的错误.
3、对比材料1与材料3,分析材料3的错误.
答案要点：①材料1中列宁的话突出的一点是指出矛盾是客观存在的,是事物的本质,是事物自身固有的,是实际生活中的实际矛盾,不是主观臆造出来的、字面上的矛盾.人们思维中的矛盾不过是客观事物的矛盾在人们意识中的反映.显然是正确的,唯物辩证法的观点.②材料2中杜林把矛盾归结为一个范畴、概念,当作纯粹的主观的思想的东西,明确指出矛盾不属于现实.与材料1完全对立.其根本错误在于否认矛盾的客观存在,把矛盾当作思想主观臆造的.③材料3中艾耶尔公开否认自然界中存在矛盾,又将矛盾当作字面上的、语句上的陈述中的矛盾, 同样是否认矛盾的客观性,和唯物辩证法的观点完全对立.这是他的根本错误.

“生产方式是决定社会发展的最终决定力量”是正确的
生产方式是社会存在和发展的最终决定力量 马克思主义对生产方
式在社会发展中作用的科学论断.人类社会的存在和发展,必须要有物质
生活条件：人类生存于其中的自然环境即地理环境；一定数量、质量和密
度的人口；人类生存所必需的物质资料的生产方式,其中生产方式最为重
要.生产方式是人们获得社会生活所必需的物质资料的方式,它是生产力
和生产关系的统一.生产力是生产方式的物质内容,生产关系是生产方式
的社会形式,两者辩证地联系着：生产力决定生产关系；生产关系反作用
于生产力.生产方式是最重要的物质生活条件,是社会存在和发展的最终
决定力量,表现在：（1）人们只有以一定的生产方式从事物质生产,才能获
得生存所必需的物质资料,才能为从事其他社会活动提供物质的前提和
条件,停止了生产,社会就要灭亡.因此,生产方式是社会赖以存在和发展
的基础.（2）生产方式决定社会制度的性质,制约着整个社会生活、政治生
活和精神生活的过程；生产方式的变化,必然或迟或早地引起全部社会制
度、社会思想、政治观点和设施的变化.（3）生产方式是划分社会类型的基
本标志.人类社会经历了原始公社制、奴隶制、封建制、资本主义和社会主
义—共产主义等五种生产方式.正是生产方式的更替,推动人类社会从低
级向高级发展.（4）地理环境和人口因素对社会发展的作用,只有在一定
的生产方式中才能实现.

As I see it,the best holiday destination in China is the West Lake.Located in the inner city of Hangzhou,it extends over 2000 miles away.When you wander along the lake,you can breathe in the fresh air,appreciate the graceful willows on either side,or even better,go boating to your heart's content on the lake.There are many tourist attractions there,such as the broken bridge,and Lei Feng Tower.The legend says that a white snake was crushed down by the tower because it fell in love with a human being.How fascinating!
when the holiday comes over,don't hesitate to go to the West Lake.Its natural beauty,fascinating stories,and friendly locals all make it the best holiday destination in China.

焚烧秸秆既是资源的浪费,又是无耐的选择.
首先大家都知道秸秆是一种资源,但由于其收集的季节性和其分散广、重量轻的物理特性和资源的价值属性低的特点,注定了收集与利用的困难.
其次,秸秆持续全量还田也不利于农民的播种以及影响植物生长.所以,秸秆是收集利用较难的可再生资源.

把多个底数不同的对数函数放在同一个平面直角坐标系中,底数大的函数其图象的x轴以上部分越靠近右边.反之也成立.

1) 矛盾的同一性和斗争性是同一矛盾性质相反的两重基本属性,它们本身就是对立统一的关系.对立表现在：矛盾的同一性是指矛盾双方相互吸引、相互联结的性质和趋势.斗争性是指矛盾双方相互排斥、相互否定的性质和趋势.矛盾同一性是有条件的、暂时的,因而是相对的；斗争性是无条件的、永恒的,因而是绝对的. （2）统一表现在：二者紧密联结、不可分割.一方面,矛盾同一性离不开斗争性,唯物辩证法所理解的同一是以差别和对立为前提的,没有斗争性就有同一性,同一性必然为斗争性所制约.另一方面,斗争性也离不开同一性.斗争性是具有在内在本质联系的两方面的斗争性,是寓于矛盾统一体中斗争性,没有同一性也就没有斗争性.(3) 建构社会主义和谐社会是党的十六届四中全会提出的战略任务,社会主义和谐社会的实质是指以人为主体的社会和谐发展状态.它包括人与自然之间、人与人、社会结构（不同社会阶层之间）的和谐.这一理论和实践对于不断推进社会主义现代化建设事业,促进经济社会各方面协调、快速发展,顺利实现全面建设小康社会的奋斗目标有重要意义.（4）建构社会主义和谐社会的哲学理论依据是矛盾同一性和斗争性辩证关系的原理.社会的和谐是矛盾同一性的具体表现,它是对立中的和谐.依据是矛盾同一性和斗争性辩证关系的原理,为了完成新时期建构社会主义和谐社会的战略任务,我们必须为了维护社会的和谐,就必须同破坏社会不和谐的现象作斗争,如同恐怖势力、邪教、贪污腐败、盗窃、抢劫等作斗争.对影响社会和谐因素的斗争、克服,是社会和谐的重要前提条件 ,否则社会和谐无从谈起
