1. 没想到小伙子也是与非门什么意思
摘要 与非门"是数字电路的一个术语.举个例子:有一个城门要持有通行证才能开门,甲乙两人都有证,甲自己进去,门打开.乙自己进去,门也开.甲乙俩同时进,门也开.当甲乙都不进时,门是不开的.
2. 高中闭合电路的思考,请理论天才回答!谢谢,
是电势能!
相信楼主应该知道,电路之所以可以工作,是因为电路中有电流。
电流就是正电荷的定向移动。
然而是什么迫使正电荷作定向移动呢?
是电压!
何为电压?
电压就是电势差。
电势差迫使正电荷从高电压流向低电压。
电势从某种角度讲,其实就是一种特殊的势能。
仍然相信,楼主还应该知道当势能作正功的时候,势能转换成了物体的动能。
然而在电路中,当电流对电阻做功的时候,电势做正功。
既然电势做了功,那么电势能就一定转换成了其他形式的能。
是动能?不,电阻速度依然是0m/s
是重力势能?不,电阻的离地高度没有发生变化
是弹性势能?不,电路里没有弹簧。
…………
排除了一切可能后,楼主一定发现电阻在发热。
所以电势能是转换成了内能。
故电阻上产生的热是从电势能转换来了。
补:导线中有电阻那么也就必然存在电势的升降。但是,楼主要知道,电阻两端的电势差是和该电阻的大小是成正比的。电阻越大,那么阻碍电荷通过的能力就越大,但是这个时候,其两端电压也越大,那么提供电荷运动的能量也就越大。电阻和电压一个阻碍电荷运动,一个提供电贺运动的能量,从而最终达到一个平衡,使每个电阻两端的电压提供的使电荷运动的能量,正好和该电阻对于电荷运动的阻碍持平,使其在微观上受力平衡,从而使电路各段电流相等。

5. 纳达尔的英文简介
Zinedine Yazid Zidane (born 23 June 1972 in Marseille, France), popularly nicknamed Zizou is a former French football player of Kabyle ethnicity, whose parents immigrated to France from Kabylie, Algeria. Zidane has starred for both the French national team and four European club teams, most recently Real Madrid.
In the 1998 World Cup final, Zidane attracted international attention with two headed goals against Brazil that won his country's first ever FIFA World Cup title. He contributed to his teams' victories in the Euro 2000, the UEFA Champions League, and domestic championships in Italy and Spain.
Zidane was elected FIFA World Player of the Year a record-equalling three times (1998, 2000, 2003) and was named European Footballer of the Year in 1998. The world-record fee of 66 million for his transfer to Real Madrid in 2001 remains unequalled. In 2004, he topped the UEFA Golden Jubilee Poll on Best European football player of the past 50 years, and was included in the FIFA 100, Pelé's list of the 125 greatest living footballers. At the 2006 FIFA World Cup, he played an inspiring role in his team's advancement to the final and was named Most Outstanding Player of the tournament, receiving the Golden Ball.
As announced on 25 April 2006,[2] Zidane retired from football after the 2006 World Cup Final on 9 July 2006
Early career, Cannes and Bordeaux (1988–1996)
Zidane got his start in football at an early age when he joined the junior team of US Saint-Henri, his local club in the La Castellane district of Marseille. On the recommendation of Saint-Henri's coach, he was then signed by Septemes Sports Olympiques. At the age of 14, Zidane left Septemes and participated in the first year junior selection for the league championship, where Jean Varraud, AS Cannes' recruiter, took notice of him. Zidane went to Cannes for what was intended to be a six-week stay, but remained at the club for four years to play with professionals. Afterwards, Zidane spent four years with FC Girondins de Bordeaux, leading them to victory in the 1995 Intertoto Cup and to a 2nd place in the 1995/96 UEFA Cup tournament. In Bordeaux, he met Bixente Lizarazu and Christophe Dugarry, with whom he played a set of midfield combinations that would become the trademark of both Bordeaux and the 1998 French national team. In 1996, he was transferred to Italy's Juventus F.C. for a fee of £ 3 million.
[edit] Turin and Madrid (1996–2006)
At Juventus, Zidane was one of the top players of Marcello Lippi's team, along with Didier Deschamps, Alessandro Del Piero, and Edgar Davids. His team won two Serie A titles and reached two consecutive UEFA Champions League finals, in 1997 and 1998, losing both, the latter to the Spanish club Real Madrid.
In 2001, Zidane was transferred to Real Madrid on a four-year contract. The transfer fee was 66 million, the highest in football history. His fellow Galacticos at Madrid included Raúl González, Luís Figo, Ronaldo, Roberto Carlos, and later David Beckham. He scored a spectacular winning goal in a 2-1 win over the German team Bayer Leverkusen in the 2001-2002 Champions League final at Glasgow's Hampden Park.
On 7 May 2006, Zidane played his last home game for Real Madrid at the Santiago Bernabéu stadium. His team-mates wore special jerseys that had ZIDANE 2001–2006 written on the bottom of the club logo. The Real Madrid fans gave him a warm reception and kept cheering him throughout the game. The opposing team was Villarreal CF, and the game ended in a 3-3 draw. He scored the second goal for Real Madrid. After the game, Zidane swapped jerseys with Juan Román Riquelme, the Villarreal CF and Argentinian midfielder. Zidane was given an ovation by spectators chanting "merci", which left him in tears.
Zidane holds al citizenship of both France and Algeria, and therefore could have played for Algeria. However, coach Abdelhamid Kermali denied him a position on the team, arguing that the young midfielder was not fast enough.
He earned his first cap with the French national football team on 17 August 1994, coming on as a substitute in the 63rd minute of a friendly match against the Czech Republic. France was behind 0-2 when Zidane came on and scored two goals for a 2-2 draw.
At that time, manager Aimé Jacquet had planned to field the team around Manchester United star Éric Cantona, but after Cantona earned a year long suspension in January of 1995 (he launched a 'kung-fu' style kick against an allegedly abusive Crystal Palace fan, Matthew Simmons), Jacquet rearranged the team and positioned Zidane as playmaker. Despite criticism from fans and pundits regarding the choice of players, France made it to the semi-finals of the Euro 1996, the Czechs beat France on 6-5 on penalties (0-0 after extra time).
[edit] 1998 World Cup
Zidane was a member of the French national football team that won the 1998 FIFA World Cup. During France's second match of the first round, he received a red card and a two-game suspension in a 4-0 win over Saudi Arabia for stamping on Saudi Arabia's team captain Fuad Amin. Reports from people close to Zidane stated that Amin had provoked him verbally.[3] After scoring in the penalty shootout in the quarter-final against Italy, he scored his only regular goals of the tournament in the final against Brazil; both goals were headers off corner kicks ring the first half. France won the match 3-0 and obtained their first – and only to date – World Cup title.
[edit] 2000 European Championship
In the Euro 2000 tournament, Zidane helped his team reach the final with inspired play and important goals. He scored a direct free kick in the quarter-final against Spain and a golden goal penalty in the semi-final against Portugal. France went on to win the tournament by defeating Italy in the final, making it the first team in 34 years to hold both the World Cup and the European Cup. Subsequently, his team was ranked 1st in the world.
[edit] Injuries, retirement and comeback (2002–2006)
Zidane in year 2004.A thigh injury prevented Zidane from playing in France's first two matches of the 2002 FIFA World Cup. He rushed back from his injury to play in the third game, but could not perform at his usual level.[4] France was eliminated in the first round without scoring a single goal, and the attempt at defending the World Cup title was unsuccessful.
In the Euro 2004 tournament, Zidane and his team started strongly, and he scored a free kick and a penalty in a come-from-behind victory against England in the group stage. On 12 August 2004, after France was upset in the quarter-finals to the eventual winners, the Greek national football team, Zidane retired from international football.[5]
However, after France experienced problems in qualifying for the 2006 FIFA World Cup, Zidane announced on 3 August 2005 that he was coming back to play for France and was reinstated as captain of the national team.[6] He made his competitive return in the 3-0 FIFA World Cup qualifier win against the Faroe Islands on 3 September 2005, and France went on to win their qualifying group.[7]
On 25 April 2006, after an injury-plagued season at Real Madrid, Zidane announced that he would retire from professional football following the 2006 FIFA World Cup finals in Germany.[8]
On 27 May 2006, Zidane earned his 100th cap for France in a 1-0 victory over Mexico at the Stade de France in Saint-Denis on the outskirts of Paris. It was his last match in the stadium, and he became only the fourth French player after Marcel Desailly, Didier Deschamps and Lilian Thuram to earn a hundred national caps. He was substituted early in the second half.[9]
[edit] 2006 World Cup
A French girl celebrating "Zizou"In the closing minutes of France's second match of the 2006 FIFA World Cup, against South Korea, Zidane received a yellow card for a late tackle, his second booking of the tournament. As a result, he was suspended from the third and final match of the group stage.[10] France nonetheless beat Togo 2-0, allowing Zidane to play in the knockout stage, from which he would score or assist in every match afterwards.[11] He returned to the pitch in the Round of 16 match against Spain. Zidane set up Patrick Vieira for the second goal by sending a free kick into the penalty area. During stoppage time, he scored the final goal of the match for a 3-1 victory.
The win sent France into a quarter-final against defending champions Brazil, in a rematch of the 1998 final. Zidane's set piece free-kick led to a goal by Thierry Henry, giving France a 1-0 win over the Seleção. Despite the score, France had thoroughly outplayed Brazil in the match, only facing one shot on goal, while Zidane created numerous scoring chances with his dribbles past defenders, displaying some of his trademark juggling as Brazillians swarmed around him. He was named Man of the Match by FIFA's Technical Study Group.[12] In the semi-final against Portugal four days later, Zidane scored a penalty kick against Ricardo for the only goal of the match and saw France through to the final against Italy.
On 9 July, Zidane played his second World Cup final—his final game—and scored in the 7th minute from the penalty spot with a chip shot that hit the crossbar before narrowly bouncing behind the goal line. He became one of only four footballers to achieve the feat of scoring in two different World Cup finals, sharing the honour with Pelé, Paul Breitner, and Vavá. This goal also made him one of the top goalscorers in World Cup final matches, with 3 goals, tied for first place with Vavá, Geoff Hurst and Pelé. He was sent off (see below) in the 110th minute, and thus did not participate in the penalty shootout which Italy won 5-3. Despite the subsequent controversy over his offence in the final, Zidane was awarded the Golden Ball as Best Player in the 2006 World Cup.[13]
[edit] Confrontation with Marco Materazzi
Zinedine Zidane headbutting Marco Materazzi ring the 2006 World Cup Final (see animated image, video, front angle video)In the 110th minute of the World Cup final against Italy, Zidane was sent off for headbutting Marco Materazzi in the chest in an off the ball incident. The two players exchanged words before Zidane began to walk away from him. Materazzi then said something to Zidane, who turned around, made a run-up and head-butted Materazzi in the chest, sending him to the ground. Although play was halted, referee Horacio Elizondo did not appear to have seen the confrontation. According to match official's reports, Fourth official Luis Medina Cantalejo informed Elizondo of the incident through his earphones. After consulting his assistant referees, Elizondo showed Zidane the red card and sent him off.
[edit] Provocation
Since video footage suggested that Materazzi had provoked Zidane, newspapers had lip readers try to determine what Materazzi had said, coming up with a variety of insults. In his first, highly awaited comments since the World Cup final, the French soccer star only partly explained what caused him to react in fury and head-butt an Italian opponent: repeated harsh insults about his mother and sister.[14] Materazzi admitted insulting Zidane, but said that Zidane's behavior had been very arrogant. He stressed that the insults had been trivial.[15][16] Zidane later stated that Materazzi had seriously and repeatedly insulted his mother and his sister and that he would "rather have taken a blow to the face than hear that". He also apologized to viewers, particularly children and ecators, but said that he did not regret his offence because he felt that this would condone Materazzi's actions.[17] Two months later, in continuing to assert that his comments had been trivial, Materazzi refused to apologize to Zidane, but stated his desire for reconciliation. He also offered his version of events, claiming that after grabbing Zidane's shirt, Zidane had sarcastically offered it to him, and that he replied to Zidane that he would prefer his sister.[18]
[edit] Reactions
After the final, President Jacques Chirac hailed Zidane as a national hero and called him a "man of heart and conviction".[19] Chirac later added that he found the offence to be unacceptable, but that he understood that Zidane had been provoked.[20] President Abdelaziz Bouteflika of Algeria expressed his solidarity with Zidane in a letter of support.[21] French newspaper Le Figaro called the headbutt "odious" and "unacceptable".[22] The editor-in-chief of French sports daily L'Équipe compared Zidane's greatness to Muhammad Ali's, but added that Ali, Jesse Owens and Pelé had never "broken the most elementary rules of sport" as Zidane had. He questioned how Zidane could explain the offence to "millions of children around the world", but apologized the following day.[23] A commentator for TIME magazine regarded the incident as a symbol for Europe's "grappling with multi-culturalism".[24] Zidane's sponsors announced that they would stick with him.[25] The incident was extensively lampooned on the internet and in popular culture.
FIFA investigation
In light of Zidane's statements, FIFA opened disciplinary proceedings to investigate the incident.[26] FIFA also affirmed the legality of Horacio Elizondo's decision to send Zidane off, rejecting claims that fourth official Luis Medina Cantalejo had illegally relied on video transmission before informing Elizondo about Zidane's misconct.[27] As a result of its investigation, FIFA issued a CHF5000 fine and a two-match ban against Materazzi, while Zidane received a three-match ban and a CHF7500 fine. According to FIFA, both players had stressed that Materazzi's comments had been defamatory, but not of a racist nature. Since Zidane was already retired at the time, he voluntarily served three days of community service on FIFA's behalf, as a substitute for the three-match ban.[28]

Nadar was born in Paris (although some sources state Lyon). He was a caricaturist for Le Charivari in 1848. In 1849 he created the Revue comique and the Petit journal pour rire. He took his first photographs in 1853 and in 1858 became the first person to take aerial photographs.
Nadar portrait of Sarah BernhardtAround 1863, Nadar built a huge (6000 m³) hot air balloon named Le Géant ("The Giant"), thereby inspiring Jules Verne's Cinq semaines en ballon (Five Weeks in a Balloon). The "Géant" project was unsuccessful and convinced him that the future belonged to heavier-than-air machines. Afterwards "The Society for the Encouragement of Aerial Locomotion by Means of Heavier than Air Machines" was established, with Nadar as president and Jules Verne as secretary.
In April 1874, he lent his photo studio to a group of painters, thus making the first exhibition of the Impressionists possible. He photographed Victor Hugo on his death-bed in 1885. He is credited with having published (in 1886) the first photo-interview (of famous chemist Michel Eugène Chevreul, then a centenary), and also took erotic photographs.
On his passing in 1910, Nadar was buried in Le Père Lachaise Cemetery in Paris. The character of "Michel Ardan" in Verne's De la Terre à la Lune (From Earth to the Moon) is inspired by Nadar.

6. 上学读书到底是有用的还是没用的
上学也不是读书,只不过是做作业,考试,得到一个所谓的大学准入资格。就算你上学,你也不是在读书,你只是重复无用功,反反复复背书、背公式,而课本上的知识又少又肤浅,浪费精力、变成近视、影响发育。其实,你没学到什么,只是在这个体制下获得了一个资格。上学本身不是在读书,而是一种普遍的社会现象。读书是什么概念,获取知识,形成自己的价值观,获得心灵的升华,数学课本、语文课本、物理书、化学书,都写了什么,你通过这些书获得了什么思想呢?上学本身是没用的,只是有个资格,就看你敢不敢打破自己的固有观念,你可以自己学编程、舞蹈、画画等,作为一技之长,然后走入社会,只是你不敢,因为你不知道,知道了也不知从何下手,家长也逼迫你不能走自己的路。一般人是做不来的,所以,你就老老实实写作业,定时交些补课费呗。
7. 仙童公司(Fairchild半导体公司)的八天才是哪八位
公司简介“仙童半导体”成立于1957年,但提到“仙童”,就不得不先提起另外的一段故事,那就是成就了“二十世纪最伟大发明”的“晶体管之父” 的肖克利(W.Shockley)博士,1955年肖克利离开贝尔实验室返回故乡圣克拉拉,创建了"肖克利半导体实验室"。不久,因仰慕"晶体管之父"的大名,无数的求职信像雪片般飞到肖克利办公桌上。第二年,八位年轻的科学家从美国东部相继来到硅谷,加盟肖克利实验室。他们是:诺依斯(N. Noyce)、摩尔(R.Moore)、布兰克(J.Blank)、克莱尔(E.Kliner)、赫尔尼(J.Hoerni)、拉斯特(J.Last)、罗伯茨(S.Boberts)和格里尼克(V.Grinich)。他们的年龄都在30岁以下,风华正茂,学有所成,都正处在创造能力的巅峰。他们之中,有获得过双博士学位者,有来自大公司的工程师,有著名大学的研究员和教授,这也是当年美国西部从来没有过的英才大集合。29岁的诺依斯是八人之中的长者,也是"投奔"肖克利最坚定的一位。当他飞抵旧金山后所做的第一件事,就是倾囊为自己下一所住所,决定永久性定居,根本就没有考虑到工作环境、条件和待遇。其他七位青年,来硅谷的经历与诺依斯大抵相似。
可惜,肖克利是天才的科学家,却缺乏经营能力;他雄心勃勃,但对管理一窍不通。特曼曾评论说:"肖克利在才华横溢的年轻人眼里是非常有吸引力的人物,但他们又很难跟他共事。"一年之中,实验室没有研制出任何象样的产品。八位青年瞒着肖克利开始计划出走。在诺依斯带领下,他们向肖克利递交了辞职书。肖克利怒不可遏地骂他们是“八叛逆”(The Traitorous Eight)。青年人面面相觑,但还是义无反顾离开了那个让他们慕名而来,之后又相聚在一起的“伯乐”。不过,后来就连肖克利本人也改口把他们称为“八个天才的叛逆”。在硅谷许多著作书刊中,“八叛逆”的照片与惠普的车库照片属于同一级别,具有同样的历史价值。
编辑本段发展历程诞生“八叛逆”找到了一家纽约的摄影器材公司来给他们投资创业,这家公司名称为Fairchild,音译“费尔柴尔德”,但通常意译为“仙童”。费尔柴尔德不仅是企业家,也是发明家。他的发明主要在航空领域,包括密封舱飞机、折叠机翼等等。由于产品非常畅销,他在1936年将公司一分为二,而其中生产照相机和电子设备的就是仙童摄影器材公司。当“八叛逆”向他寻求合作的时候,已经60多岁的费尔柴尔德先生仅仅给他们提供了3600美元的创业基金,要求他们开发和生产商业半导体器件,并享有两年的购买特权。于是,“八叛逆”创办的企业被正式命名为仙童半导体公司,“仙童”之首自然是诺依斯。1957年10月,仙童半导体公司在硅谷嘹望山查尔斯顿路租下一间小屋,距离肖克利实验室和距离当初惠普公司的汽车库差不多远。“仙童”们商议要制造一种双扩散基型晶体管,以便用硅来取代传统的锗材料,这是他们在肖克利实验室尚未完成却又不受肖克利重视的项目。费尔柴尔德摄影器材公司答应提供财力,总额为150万美元。诺依斯给伙伴们分了工,由赫尔尼和摩尔负责研究新的扩散工艺,而他自己则与拉斯特一起专攻平面照相技术。
发展1958年1月,蓝色巨人 IBM公司给了他们第一张订单,订购100个硅晶体管,用于该公司电脑的存储器。到1958年底,“八叛逆”的小小公司已经拥有50万销售额和100名员工,依靠技术创新的优势,一举成为硅谷成长最快的公司。
仙童半导体公司在诺依斯精心运筹下,业务迅速地发展,同时,一整套制造晶体管的平面处理技术也日趋成熟。天才科学家赫尔尼是众"仙童"中的佼佼者,他像变魔术一般把硅表面的氧化层挤压到最大限度。仙童公司制造晶体管的方法也与众不同,他们首先把具有半导体性质的杂质扩散到高纯度硅片上,然而在掩模上绘好晶体管结构,用照相制版的方法缩小,将结构显影在硅片表面氧化层,再用光刻法去掉不需要的部分。扩散、掩模、照相、光刻,整个过程叫做平面处理技术,它标志着硅晶体管批量生产的一大飞跃,也为"仙童"打开了一扇奇妙的大门,使他们看到了一个无底的深渊:用这种方法既然能做一个晶体管,为什么不能做它几十个、几百个,乃至成千上万呢?1959年1月23日,诺依斯在日记里详细地记录了这一最伟大也被当时的人们看作是最疯狂的设想。
1959年2月,德克萨斯仪器公司(TI)工程师基尔比(J.kilby)申请第一个集成电路发明专利的消息传来,诺依斯十分震惊。他当即召集“八叛逆”商议对策。基尔比在TI公司面临的难题,比如在硅片上进行两次扩散和导线互相连接等等,正是仙童半导体公司的拿手好戏。诺依斯提出:可以用蒸发沉积金属的方法代替热焊接导线,这是解决元件相互连接的最好途径。仙童半导体公司开始奋起疾追。1959年7月30日,他们也向美国专利局申请了专利。为争夺集成电路的发明权,两家公司开始旷日持久的争执。1966年,基尔比和诺依斯同时被富兰克林学会授予“巴兰丁”奖章,基尔比被誉为“第一块集成电路的发明家”,而诺依斯被誉为“提出了适合于工业生产的集成电路理论”的人。1969年,法院最后的判决下达,也从法律上实际承认了集成电路是一项同时的发明。
1960年,仙童半导体公司取得进一步的发展和成功。由于发明集成电路使它的名声大振,母公司费尔柴尔德摄影器材公司决定以300万美元购买其股权,“八叛逆”每人拥有了价值25万美元的股票。1964年,仙童半导体公司创始人之一摩尔博士,以三页纸的短小篇幅,发表了一个奇特的定律。摩尔天才地预言说道,集成电路上能被集成的晶体管数目,将会以每18个月翻一番的速度稳定增长,并在今后数十年内保持着这种势头。摩尔所作的这个预言,因后来集成电路的发展而得以证明,并在较长时期保持了它的有效性,被人誉为“摩尔定律”,成为IT产业的“ 第一定律”。
没落60年代的仙童半导体公司进入了它的黄金时期。到1967年,公司营业额已接近2亿美元,在当时可以说是天文数字。据那一年进入该公司的虞有澄博士(现英特尔公司华裔副总裁)回忆说:“进入仙童公司,就等于跨进了硅谷半导体工业的大门。”然而,也就是在这一时期,仙童公司也开始孕育着危机。母公司总经理不断把利润转移到东海岸,去支持费尔柴尔德摄影器材公司的盈利水平。在目睹了母公司的不公平之后,“八叛逆”中的赫尔尼、罗伯茨和克莱尔首先负气出走,成立了阿内尔科公司。据说,赫尔尼后来创办的新公司达12家之多。随后,“八叛逆”另一成员格拉斯也带着几个人脱离仙童创办西格奈蒂克斯半导体公司。从此,纷纷涌进仙童的大批人才精英,又纷纷出走自行创业。结果人才纷纷离仙童而去,最终仙童中的斯波克将NSC弄成了全球第六大半导体厂商,桑德斯创立了AMD,而诺依斯和摩尔则创立了INTEL(英特尔),而这就是仙童的整个历程。[1]
编辑本段公司影响“仙童”,一个永远让世人铭记和仰慕的名字,一个对半导体界乃至全世界作出了后人无法企及的贡献。引用苹果总裁乔布斯的一句话:“仙童半导体公司就象个成熟了的蒲公英,你一吹它,这种创业精神的种子就随风四处飘扬了。”仙童半导体拥有与众不同的晶体管制作方式,扩散、掩模、照相、光刻,整个过程叫做平面处理技术,它标志着硅晶体管批量生产的一大飞跃。在1969年的半导体工程师大会,400位与会者中只有24位的履历表上没有在仙童公司的工作的经历。
