<注釋>One might well ask how many European scientists it takes to turn on a light bulb.If we think in terms of the names used for various units in the International, or meter-kilogram-second, System,a fair number are involved.Alphabetically arranged, these units are theampere, named for the French scientist Andrô Marie Ampère (775-83'); thecoulomb, after the French scientist Charles A. de Coulomb (73'-80'); thefarad and the faraday, after the British scientist Michael Faraday (79-8'7); thejoule, after the British scientist James P. Joule (88-889); thenewton, after the British scientist Sir Isaac Newton ('42-727); theohm, after the German scientist Georg S. Ohm (789-854); thevolt, after the Italian scientist Count Alessandro Volta (745-827); and thewatt, after the British scientist James Watt (73'-89). Definitions such as that ofohm, .a unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals,. take on more human connotations when we think of how human contributions to the study of electricity are memorialized in them.The dates of first recorded use of the terms in English are as follows:ampere, 88; coulomb, 88; farad, 8'; faraday, 904; joule, 882; newton, 904; ohm, 870 (suggested in 8'); volt, 873; and watt, 882.
有人可能會(huì)問(wèn)經(jīng)過(guò)了多少位歐洲科學(xué)家才點(diǎn)亮了燈泡。如果我們以國(guó)際單位制或米—千克—秒單位制中各種單位之名稱的形式來(lái)考慮的話，相當(dāng)數(shù)量的人被包括了。這些單位按字母順序排列是安培， 以法國(guó)科學(xué)家安德烈·馬里耶·安培(775—83'年）命名； 庫(kù)侖， 以法國(guó)科學(xué)家夏爾·?！さ聨?kù)侖(73'-80'年）命名； 法拉 和 法拉第， 以英國(guó)科學(xué)家邁克爾·法拉第(79—8'7年）命名； 焦耳 以英國(guó)科學(xué)家詹姆斯·皮·焦耳(88—889年）命名； 牛頓， 以英國(guó)科學(xué)家伊薩克·牛頓爵士('42—727年）命名； 歐姆， 以德國(guó)科學(xué)家格奧爾格·斯·歐姆(789—854年）命名； 伏特， 以意大利科學(xué)家亞歷山德羅·沃爾塔伯爵(745—827年）命名； 瓦特， 以英國(guó)科學(xué)家詹姆士·瓦特(73'—89年）命名。 定義諸如歐姆， .電阻單位，等于一伏特電壓加于導(dǎo)體兩端在導(dǎo)體內(nèi)部產(chǎn)生一安培電流之導(dǎo)體電阻.， 當(dāng)我們想到人們對(duì)電學(xué)做出的貢獻(xiàn)是怎樣在這之中得到紀(jì)念的時(shí)候，就帶上了更多的人文內(nèi)涵。英語(yǔ)中首次有記錄的使用這些說(shuō)法的時(shí)間如下：安培， 88； 庫(kù)侖， 88； 法拉， 8'； 法拉第， 904； 焦耳， 882； 牛頓， 904； 歐姆， 870（在8'年建議使用）； 伏特， 873；和 瓦特， 882
