Queen Victoria

Victoria, a British’s girl, created an empire on which the sun never set. Victoria (1819-1901) was queen of Great Britain and Ireland from 1837 to 1901 and empress of India from 1876 to 1901. She presided over the expansion of England into an empire of 4 million square miles and 124 million people.

Victoria was born Alexandra Victoria at Kensington Palace, London, on May 24, 1819.Alexandrina Victoria was the only child of the fourth son of King George III: Edward, duke of Kent and Strathern. Her father died a little after Victoria’s birth. Her mother was Victoria Maria Louisa of Saxe-Coburg, sister of King Leopold of the Belgians and daughter of the duke of Saxe-coburg-Saalfeld. Victoria was a lively child. A governess educated her at home. Victoria learned to speak and write French and German as easily as she spoke English. She also studied history, geography, and the Bible. She was taught how to play the piano. She had a gift for drawing and painting, a hobby that she enjoyed into her 60s. Victoria kept a detailed diary. Her

famous journal is in 111 manuscript volumes.

Queen Victoria (1819-1901) was the Queen of England during the time when her country was the most powerful country in the world. Queen Victoria is the longest monarch in British history. Her reign was the longest of any monarch in British history and came to be known as the Victorian era. Historically the Victorian age is remarkable for the growth of democracy following the Reform Bill of 1832; for the spread of education among all classes; for the rapid development of the arts and sciences; for important mechanical inventions; and for the enormous extension of the bounds of human knowledge by the discoveries of science. She became Queen at the age of 18 on Ju ne 20, 1837 because William IV, Victoria’s Uncle, had no children.At that time, the United Kingdom was already an established constitutional monarchy, in which the Sovereign held relatively few direct political powers. Privately, she attempted to influence government policy and ministerial appointments. Publicly, she became a national icon, and was identified with strict standards of personal morality.Queen Victoria tested the limits of her royal powers when the government of Lord Melbourne, the Whig who had been her mentor, fell the next year. She refused to follow precedent and dismiss her ladies of the bedchamber so that the Tory government could replace them. Her refusal brought back the Whigs until 1841. As a monarch, she put the country’s interest in heart, and she regarded it as her life. She is just a woman, but she sacrifices herself to the country. Because of her, the Britain become greater and greater and all the people remember her; the Victoria Era is spread to the world and never forgets. During her reign of 64 years, which period is Britain’s most powerful period called ―sun-never-set Empire‖. Queen’s reign in English history knows as the Victorian Era. It was a period of industrial, cultural, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire.During this period, it reached its zenith and became the foremost global power of the time. She was the last British monarch of the House of Hanover; her son and successor Edward VII belonged to the House of Saxe-Coburg and Gotha. Victoria was the first reigning monarch to use trains. Also Queen Victoria becomes a symbol of peace and prosperity in the United Kingdom. She was not one of the most intelligent rulers in the history of England, but

she was one of the most popular. Her people loved her. In my opinion, Queen Victoria is not only a monarch, but also a person who cares her people. She will respect by all the British, even the people all over the world.

Victoria first learned of her future role as a young princess during a history lesson when she

was 10 years old. Almost four decades later Victoria's governess recalled that the future queen

reacted to the discovery by declaring, "I will be good." This combination of earnestness and

egotism marked Victoria as a child of the age that bears her name. The queen, however, rejected

important Victorian values and developments. A mother of nine who hated pregnancy and

childbirth, detested babies, and was uncomfortable in the presence of children, Victoria reigned in

a society that idealized both motherhood and the family. She had no interest in social issues, yet

the 19th century in Britain was an age of reform. She resisted technological change even while

mechanical and technological innovations reshaped the face of European civilization.

Most significantly, Victoria was a queen determined to retain political power; yet unwillingly

and unwittingly she presided over the transformation of the sovereign's political role into a

ceremonial one and thus preserved the English monarchy. When Victoria became queen, the

political role of the crown was by no means clear; nor was the permanence of the throne itself.

When she died and her son Edward VII moved from Marlborough House to Buckingham Palace,

the change was one of social rather than of political focus; there was no doubt about the

monarchy's continuance. That was the measure of her reign.

Queen Victoria had large blue eyes, a cupid-bow mouth, smooth light-brown hair that darkened with age, and a receding chin. She was under 5 feet and as a girl was slender, then plump. By the time she was 26 she was stout and remained so, except after periods of illness, until the end. She had a silvery voice, enunciated excellently, without a trace of the German accent of her eldest son, and had a radiant, though rare, smile. Those she disliked, William Gladstone for example, found her somber and terrifying; her ladies, servants, and grandchildren thought she looked "so dear" and idolized her.

The most important person in her life was her husband, Albert. Attracted by Albert's good looks and encouraged by her uncle Leopold, Victoria proposed to her cousin on Oct. 15, 1839, just five days after he had arrived at Windsor on a visit to the English court. She described her impressions of him in the journal she kept throughout her life: "Albert really is quite charming, and so extremely handsome, a beautiful figure, broad in the shoulders and a fine waist; my heart is quite going." They were married on Feb. 10, 1840, the queen dressed entirely in articles of British manufacture. She loved him very much and always listened to his advice. They set a great example of devotion to family. Victoria had nine children. Her first child, Victoria, later empress of Germany, was born in 1840, and the prince of Wales, later Edward VII, in 1841. Their nine children and 26 of their 34 grandchildren who survived childhood married heirs to thrones of Spain, Russia, Sweden, Norway, and Romania. Because this, Victoria became known as the ―Grandmother of Europe.‖The marriage of her daughters into other royal families, and the likelihood that her children bore a mutant gene for hemophilia, both affected the following

generations of European history. Victoria had traditional views on the role of the wife and mother, and though she was Queen and Albert was Prince Consort, he shared government responsibilities at least equally. Albert died in 1861 at the young age of 42. Queen Victoria was heartbroken. Victoria plunged into deep mourning and avoided public appearances.Her prolonged mourning lost her much popularity. As a result of her seclusion, republicanism temporarily gained strength, but in the latter half of her reign, her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration.During her lifetime she published her Letters, Leaves from the Journal of our Life in the Highlands and More Leaves. In her old age, Victoria was enormously popular. Jubilees were held in 1887 and 1897 to celebrate the 50th and 60th years of the longest English reign. The queen was not highly intelligent, but her conscientiousness and strict morals helped to restore the prestige of the crown and to establish it as a symbol of public service and imperial unity. Having witnessed a revolution in British government, huge industrial expansion and the growth of a worldwide empire, Victoria died on 22 January 1901 at Osborne House on the Isle of Wight. She is buried at Windsor Castle beside Prince Albert. She was succeeded by her son, Albert Edward, Prince of Wales. He became King Edward VII.

The Victorian Era of the United Kingdom was the period of Queen Victoria's reign from June 1837 to January 1901. This was a long period of prosperity for the British people, as profits gained from the overseas British Empire, as well as from industrial improvements at home, allowed a large, educated middle class to develop. Some scholars would extend the beginning of the period-as defined by a variety of sensibilities and political concerns that have come to be associated with the Victorians-back five years to the passage of the Reform Act 1832.

The era was preceded by the Georgian period and succeeded by the Edwardian period. The latter half of the Victorian era roughly coincided with the first portion of the Belle Epoque era of continental Europe.

The era is often characterized as a long period of peace, known as the Pax Britannica, and economic, colonial, and industrial consolidation, temporarily disrupted by the Crimean War, although Britain was at war every year during this time. Towards the end of the century, the policies of New Imperialism led to increasing colonial conflicts and eventually the Anglo-Zanzibar War and the Boer War. Domestically, the agenda was increasingly liberal with a number of shifts in the direction of gradual political reform and the widening of the voting franchise.

The population of England had almost doubled from 16.8 million in 1851 to 30.5 million in 1901. Ireland's population decreased rapidly, from 8.2 million in 1841 to less than 4.5 million in 1901.

In the early part of the era the House of Commons was dominated by the two parties, the Whigs and the Tories. From the late 1850s onwards the Whigs became the Liberals even as the Tories became known as the Conservatives. These parties were led by many prominent statesmen including Lord Melbourne, Sir Robert Peel, Lord Derby, Lord Palmerston, William Gladstone, Benjamin Disraeli and Lord Salisbury. The unsolved problems relating to Irish Home Rule played a great part in politics in the later Victorian era, particularly in view of Gladstone's determination to achieve a political settlement.

The Victorian era was the great age of the English novel—realistic, thickly plotted, crowded with characters, and long. It was the ideal form to describe contemporary life and to entertain the middle class. Writers like Charles Dickens, William Thackeray, George Eliot, Thomas Hardy showed their primary concern is about the people in the society with sympathy for the poor and the unfortunate and became the major voice of the literary world by presenting a faithful picture of the horrible capitalist England. The novels of Charles Dickens, full to overflowing with drama, humor, and an endless variety of vivid characters and plot complications, nonetheless spare nothing in their portrayal of what urban life was like for all classes. Charles Dickens hates the social evils and intends social reform by exposing and criticizing in his works all the poverty, injustice, hypocrisy and corruption in the 19th –century England. He thinks that the state should intervene to control the rapacity of landlords and capitalists. He wants improvement in the life of the poor, but is afraid of a real revolution. Dickens is a humanitarian who pours all his love and sympathy for those poor, weak, innocent, injured and neglected good people. William Makepeace Thackeray is best known for Vanity Fair (1848), which wickedly satirizes hypocrisy and greed. The sub-title of the book emphasizes the fact that the writer’s intention was not to portray individuals, but the bourgeois and aristocratic society as a whole. Building his plot around the fates of Amelia Sedley and Rebecca (Becky) Sharp, Thackeray managed to show a picture of the life of the ruling classes of England. The novel remains a classical example of social satire up to the present day. The title was taken form Bunyan’s pilgrim’s progress. Thomas Hardy (1840-1928) seems to belong to the present rather than to a past age. In style, Hardy is direct and simple, aiming at realism in all things. Hardy makes man an insignificant part of the world, struggling against powers greater than himself,---sometimes against systems which he cannot reach or influence, sometimes against a kind of grim world-spirit who delights in making human affairs go wrong. He is, therefore, hardly a realist, but rather a man blinded by pessimism; and his novels, though generally powerful and sometimes fascinating, are not pleasant or wholesome reading. From the reader’s view point some of his earli er works, like the idyllic love story Under the Greenwood Tree (1872) and A Pair of Blue Eyes (1873), are the most interesting. Hardy became noted when he published Far from the Madding Crowd (1874). The Return of the Native (1878) and The Woodlanders are generally regarded as his masterpieces; but two novels of our own day, Tess of the D’Ubervilles (1891) and Jude the Obscure (1895), are better expressions of Hardy’s literary art and of his gloomy philosophy.

Among the Victorian masters of nonfiction were the great Whig historian Thomas Macaulay and Thomas Carlyle, the historian, social critic, and prophet whose rhetoric thundered through the age. Influential thinkers included John Stuart Mill, the great liberal scholar and philosopher; Thomas Henry Huxley, a scientist and popularizer of Darwinian theory; and John Henry, Cardinal Newman, who wrote earnestly of religion, philosophy, and education. The founders of Communism, Karl Marx and Friedrich Engels, researched and wrote their books in the free environment of England. The great art historian and critic John Ruskin also concerned himself with social and economic problems. Matthew Arnold's theories of literature and culture laid the foundations for modern literary criticism, and his poetry is also notable.

The preeminent poet of the Victorian age was Alfred, Lord Tennyson. Although romantic in subject matter, his poetry was tempered by personal melancholy; in its mixture of social certitude and religious doubt it reflected the age. The poetry of Robert Browning and his wife, Elizabeth Barrett Browning, was immensely popular, though Elizabeth's was more venerated during their lifetimes. Browning is best remembered for his superb dramatic monologues. Rudyard Kipling, the poet of the empire triumphant, captured the quality of the life of the soldiers of British expansion. Some fine religious poetry was produced by Francis Thompson, Alice Meynell, Christina Rossetti, and Lionel Johnson.

There were many famous quotes by Queen Victoria.

"We are not interested in the possibilities of defeat; they do not exist."

"A marriage is no amusement but a solemn act, and generally a sad one."

"None of you can ever be proud enough of being the child of SUCH a Father who has not his equal in this world -- so great, so good, so faultless. Try, all of you, to follow in his footsteps and don't be discouraged, for to be really in everything like him none of you, I am sure, will ever be. Try, therefore, to be like him in some points, and you will have acquired a great deal."

"The Queen is most anxious to enlist everyone who can speak or write to join in checking this mad, wicked folly of Woman's Rights with all its attendant horrors on which her poor, feeble sex is bent, forgetting every sense of womanly feeling and propriety."

"His purity was too great, his aspiration too high for this poor, miserable world! His great soul is now only enjoying that for which it was worthy!"

"We placed the wreaths upon the splendid granite sarcophagus, and at its feet, and felt that only the earthly robe we loved so much was there. The pure, tender, loving spirit which loved us so tenderly, is above us -- loving us, praying for us, and free from all suffering and woe -- yes, that is a comfort, and that first birthday in another world must have been a far brighter one than any in this poor world below!"

Erwin教程 erwin是一个数据库关系实体模型(ER Model)设计工具,与Power Designer(Sybase公司开发)成为最常用的两种数据库设计工具。目前该工具被CA收购,成为CA数据库解决方案中的一个关键部分。与微软的Vision相比,erwin只能设计er model,而且设计界面选项较多,相对来说并不那么友好,增加了使用的难度。但如果你是一个出色的数据库应用开发者,那你一定会发现erwin的好处。因为在设计模型层次和复杂度提高以后,visio难以应付众多的数据对象设计和对象之间的关系设计。而且erwin提供了数据库正向工程、逆向工程和文档正向工程功能,可以把设计直接实施到数据库后者把数据库中的对象信息读到erwin设计中,也可以生成设计文档,格式还可以自动定义。在本教程中,将告诉大家我是怎样简单的使用erwin来进行数据库设计的。这里强调了简单二字,就是说有很多只有20%机会用到的80%的功能本教程是不会介绍的。本文用到的erwin版本是4.0。 教程一:Table & Subject Areas Table是数据库中最基本的物理元素,保持了应用的持久数据。在普通的信息系统数据库结构设计中,有90%的工作是在设计table。而table的字段定义和表间的关系,也反映了整个系统的数据流图和大致的业务流程。 Subject Areas是erwin提供逻辑元素,在实际数据库中并不存在。它的含义是把物理元素和逻辑元素按照实际意义划分成各个主题,在主题域中添加对元素的引用,起到一个按图索骥和目录的作用。有一个缺省的主题域Main Subject Area,所有的元素都会在该主题域中存在。在我本人的设计方法中,我会新建诸如“参数表”,“分户表”,“控制表”,“临时表”,“明细表”,“日志表”和“总帐”等主题域。 下面跟着我的说明,一步一步来设计table: 装好erwin4.0后,打开程序。提示你是创建一个新模型还是打一个已有的,选择创建新模型。在Model Type中选择Physical(物理模型),下面的Target Database默认值就是Oracle8.x,使用默认值,点击OK,创建了一个空白的模型。

维多利亚女王 Victoria's Golden Jubilee

1887年6月21日——英国维多利亚女王在位50周年庆典 ppt2 维多利亚女王 全名亚历山德琳娜·维多利亚(Alexandrina Victoria) 出生1819年5月24日伦敦肯辛顿宫 过世1901年1月22日(81岁)怀特岛郡,奥斯本楼 安葬1901年2月4日温莎福摩 签章 ppt3 年轻时候的维多利亚,油画;中年时期的维多利亚,摄影 ppt4 主线: 出生与家庭 童年时期 继位 影响 ppt5 家庭背景: 家族汉诺威王朝 父亲爱德华亲王,授予的爵位是肯特与斯特拉森公爵,当时英王乔治三世的第四个儿子。 母亲维多利亚公主,后面的萨克森-科堡-萨尔费尔德是她的头衔,她是一位德国公主。(她的兄弟是比利时第一任国王鳏夫利奥波德。) ppt6 出生时,维多利亚是第五顺位继承人。因为当时英国皇室中维多利亚这一辈的就只有她一人。 在她之前的四位继承人分别是:摄政王(乔治四世)、约克公爵、克拉伦斯公爵(威廉四世)、维多利亚的父亲肯特公爵。 维多利亚的祖父、父亲都在1820年去世,去世时间相距一个星期,而约克公爵在1827年去世。所以英国王位的传承顺序就是从乔治三世——乔治四世——威廉四世,维多利亚则是威廉四世之后的法定继承人。 Ppt7 童年时期: 维多利亚的父亲在1820年去世,维多利亚在母亲的严格监督下成长。 维多利亚日后称她的童年“相当忧郁”("rather melancholy")。维多利亚的母亲对她非常严格,她在与其他儿童隔绝的肯辛顿系统下成长。这是一套由肯特公爵夫人与她的顾问约翰·康罗伊所设计的严格规定。这套系统避免公主同“不良”的人见面(其中包括维多利亚父系的大部分家族成员),并设计使她软弱、依赖他们。 ppt8 童年成长的地方,肯辛顿宫 ppt9 肯辛顿宫

第一章基本概念 1.1 数据模型(Modal) 数据模型是数据实体(Entity)和数据实体间的关系(Relationship)总和。可以简单的理解认为数据实体就是对应数据库表,实体间的关系就是表之间的关系。 1.2 视图 Erwin对数据模型提供两种视——逻辑视图、物理视图。 1.2.1 逻辑视图(Logical) 是以业务需求的概念对数据模型进行描述。通俗的说,在逻辑视图中我们可以用中文或描述性的语言来描述数据实体(表)和数据实体的属性(字段)。下面就是一个对车辆信信息实体的逻辑视图。 1.2.2 物理视图(Physical) 物理视图与逻辑视图一一对应,物理视图是针对一种具体的数据库进行逻辑视图的物理映射。通俗的说,在物理视图中我们必须为每一个在逻辑视图中出现的数据实体(表)指定一个可被具体数据库接纳的表名称,譬如我们使用MySQL作为我们的数据库实现,我们就必须为具体的实体指定一个数据库表名(英文单词或词组),同样的对实体属性(字段)的命名也需进行转换,数据类型也需要具体为数据库支持的数据类型。下面就是对应车辆信息实体针对MySQL数据的物理视图。

Victoria 4.46 修复硬盘坏道图文教程全新

在“标准”选项卡中选择硬盘然后进入“测试”选项卡,起始LBA和结束LBA一般采用默认,也就是全盘检查。 图1 选择硬盘 图2 选择扫描方式

功能项说明: “忽略” 硬盘在扫描的过程发现了坏道和超时的磁道时不处理,只检测不修复。“擦除” 硬盘在扫描的过程发现了坏道和读取超时的扇区进行擦除处理。对逻辑坏道修复效果比较好。 “重映射” 将坏道写入到坏道列表G-list中,并从保留扇区中拿出同容量的扇区进行替换,硬盘容量不变。适合少量坏扇区的修复。 “恢复”恢复应该是使用反相磁化修复的方法修理磁道。所谓反相磁化就是通过用软件的指令迫使磁头产生不同极性及强度的磁力,对坏扇区和坏道进行反复加磁,使这些扇区和坏道的磁介质重新获得完好的磁记录特性。以便继续使用,但是会损耗磁头,特别是有大量坏扇区的时候。修复时间也最长。不建议使用。而且这个是付费的功能,免费版的也用不了。 扇区读取时间处的颜色为:浅灰色(<5ms)、灰色(<20ms)、深灰色(<50ms)、绿色(<200ms)、橙色(<500ms)、红色(>500ms)表示从正常到异常,读写速度由快到慢。 正常情况下应该只出现第一个和第二个方块(即浅灰色、灰色两种颜色);第三个方块(即:深灰色)则代表该处读取耗时较多;第四个和第五个方块(即:绿色和橙色)则代表此处读取异常,但还未产生坏道;第六个(即:红色)则代表此处读取吃力,马上就要产生坏道;出现×,则表示读取错误,有严重物理坏道,无法修复。 1.生活如意,事业高升。 2.前程似锦,美梦成真。 3.年年今日,岁岁今朝。 4.百事大吉,万事顺利。 5.愿与同僚,共分此乐。 6.事业有成,幸福快乐。 7.生日快乐,幸福安康。 8.幸福快乐,与君同在。

victoria硬盘扫描工具使用说明

推荐一个硬盘扫描工具,HDTune基本可以淘汰掉了,Victoria4.46汉化版。 victoria号称WINDOWS版本的MHDD,虽然4.3版本早在07年就已发布,但还是够资格称为最好的硬盘测试工具,原因1:通吃各种接口硬盘,原因2:可视化的用户界面(MS现在没人这样说了),原因3:可以在WINDOWS下使用,而且其本身也是一款G-list级的坏道修复软件,但现在网上流行的基本都是测试版本,无法使用修复功能,不过做为一款测试工具还是绰绰有余的。扇区颜色说明: 扇区读取时间处的颜色为:浅灰色(<5ms)、灰色(<20ms)、深灰色(<50ms)、绿色(<200 ms)、橙色(<500ms)、红色(>500ms)表示从正常到异常,读写速度由快到慢。 正常情况下应该只出现第一个和第二个方块(即浅灰色、灰色两种颜色);第三个方块(即:深灰色)则代表该处读取耗时较多;第四个和第五个方块(即:绿色和橙色)则代表此处读取异常,但还未产生坏道;第六个(即:红色)则代表此处读取吃力,马上就要产生坏道;出现×,则表示读取错误,有严重物理坏道,无法修复。

[ 此帖被iamet在2010-02-08 13:02重新编辑 ERASE是擦写,主要是对扫描到的坏道进行擦除,对于一些CRC错误,也就是我们常说的逻辑错误,或者不是很严重的坏块可以起到修复的作用。 REMAP是重映射,也就是重新定义坏块的LBA地址,将原坏块的地址写到硬盘的G-List 中,因为硬盘在生产的时候都会有保留容量,这个功能就是用保留容量内的好地址替换坏块。Defectoscop是缺陷探伤,是扫描硬盘物理缺陷的一个功能,它仅仅只是扫描缺陷而已,起不到修复的作用的。 对于你的情况,只是硬盘出现了大量色块,可先用ERASE功能进行全盘擦写,看是否能减少坏道,然后再使用Remap功能,记得在超时那一栏填写合适的超时值,默认是1000ms,建议先修改为250ms,扫描多次后再修改为150ms扫描,应该可以将多数色块扫描进G表。如果还是不行的话,可以试试HDDL。其实启动硬盘的SelfScan是解决色块多的最好方法,
