    摘要:本文为大家带来一篇关于法拉第的SAT写作人物素材,备考SAT的宝宝们擦亮眼睛哦,是“法拉第”不是“法拉利”。法拉第是英国著名的物理学家和化学家,下面我们就一起来看看他的平生经历和成就吧。

    SAT写作:经典人物素材之法拉第图1

    法拉第被称为“电学之父”和“交流电之父”,1831年,他作出了关于电力场的关键性突破,永远改变了人类文明。他的发现奠定了电磁学的基础,是麦克斯韦的先导。1831年10月17日,法拉第首次发现电磁感应现象,并进而得到产生交流电的方法。1831年10月28日法拉第发明了圆盘发电机,是人类创造出的第一个发电机。

    The English chemist and physicist Michael Faraday, b. Sept. 22, 1791, d.Aug. 25, 1867, is known for his pioneering experiments in electricity andmagnetism. Many consider him the greatest experimentalist who ever lived.

    英国化学家、物理学家迈克尔·法拉第,1791年9月22日,8月8日。1867年,他因在电和磁方面的开拓性实验而闻名。许多人认为他是有史以来最伟大的实验主义者。

    During the initial years of his scientific work, Faraday occupied himself mainly with chemical problems. He discovered two new chlorides of carbon and succeeded in liquefying chlorine and other gases. He isolated benzene in 1825, the year in which he was appointed director of the laboratory.

    在他从事科学工作的最初几年里,法拉第主要忙于处理化学问题。他发现了两种新的碳,并成功地液化了氯和其他气体。在1825年,他被任命为实验室主任。

    Davy, who had the greatest influence on Faraday's thinking, had shown in 1807 that the metals sodium and potassium can be precipitated from their compounds by an electric current, a process known as electrolysis.

    戴维(Davy)对法拉第的想法产生了最大的影响,他在1807年曾说过,金属钠和钾可以通过电流从化合物中析出,这一过程被称为电解。

    Faraday's vigorous pursuit of these experiments led in 1834 to what became known as Faraday's laws of electrolysis.

    法拉第对这些实验的强烈追求导致了1834年的法拉第电解定律。

    Faraday's research into electricity and electrolysis was guided by the belief that electricity is only one of the many manifestations of the unified forces of nature, which included heat, light, magnetism, and chemical affinity. Although this idea was erroneous, it led him into the field of electromagnetism, which was still in its infancy.

    法拉第对电和电解的研究是基于这样一种信念,即电只是自然界中许多统一力量的表现之一,包括热、光、磁力和化学亲和力。虽然这个想法是错误的,但它使他进入了电磁学领域,而这一领域还处于起步阶段。

    In 1785, Charles Coulomb had been the first to demonstrate the manner in which electric charges repel one another, and it was not until 1820 that Hans Christian Oersted and Andre Marie Ampere discovered that an electric current produces a magnetic field. Faraday's ideas about conservation of energy led him to believe that since an electric current could cause a magnetic field, a magnetic field should be able to produce an electric current. He demonstrated this principle of induction in 1831. Faraday expressed the electric current induced in the wire in terms of the number of lines of force that are cut by the wire.

    1785年,查尔斯·库仑(Charles Coulomb)首次展示了电荷相互排斥的方式,直到1820年,汉斯·克里斯蒂安·奥斯特(Hans Christian Oersted)和安德烈·玛丽安培(Andre Marie Ampere)才发现,电流产生磁场。法拉第关于能量守恒的观点使他相信,由于电流可以引起磁场,磁场应该能够产生电流。他在1831年论证了归纳法的原理。法拉第表示导线中被电线切割的力的数量,在导线中感应电流。

    The principle of induction was a landmark in applied science, for it made possible the dynamo, or generator, which produces electricity by mechanical means.

    感应原理是应用科学的一个里程碑,因为它使发电机或发电机成为可能,它通过机械的方式产生电能。

    Faraday's introduction of the concept of lines of force was rejected by most of the mathematical physicists of Europe, since they assumed that electric charges attract and repel one another, by action at a distance, making such lines unnecessary. Faraday had demonstrated the phenomenon of electromagnetism in a series of experiments, however.

    法拉第引入的力线概念被欧洲的大多数数学物理学家拒绝了,因为他们认为电荷相互吸引并相互排斥,通过距离的作用,使得这些线没有必要。然而,法拉第在一系列实验中证实了电磁学现象。

    This experimental necessity probably led the physicist James Clerk Maxwell to accept the concept of lines of force and put Faraday's ideas into mathematical form, thus giving birth to modern field theory.

    这种实验性的需要可能导致物理学家詹姆斯·克拉克·麦克斯韦接受力线的概念,并将法拉第的思想转化为数学形式,从而产生了现代场理论。

    Faraday's discovery (1845) that an intense magnetic field can rotate the plane of polarized light is known today as the Faraday effect. The phenomenon has been used to elucidate molecular structure and has yielded information about galactic magnetic fields.

    法拉第的发现(1845年),强烈的磁场可以旋转偏振光的平面,今天被称为法拉第效应。这一现象已被用于阐明分子结构,并产生了有关银河磁场的信息。

    Faraday described his numerous experiments in electricity and electromagnetism in three volumes entitled Experimental Researches in Electricity (1839, 1844, 1855); his chemical work was chronicled in Experimental Researches in Chemistry and Physics (1858). Faraday ceased research work in 1855 because of declining mental powers, but he continued as a lecturer until 1861. A series of six children's lectures published in 1860 as The Chemical History of a Candle, has become a classic of science literature

    法拉第在《电的实验研究》(1839,1844,1855)三卷中描述了他在电和电磁学方面的大量实验;他的化学工作被记录在化学和物理实验研究(1858年)。1855年,法拉第停止了研究工作,因为他的脑力下降了,但直到1861年,他仍是一名讲师。1860年出版的系列六部儿童讲座作为蜡烛的化学历史,已成为科学文献的经典。
