See table at measurement 克：米制质量单位，一克等于千分之一(10-3)千克 参见 measurement〔watt〕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 Andr? Marie Ampère (1775-1836); thecoulomb, after the French scientist Charles A. de Coulomb (1736-1806); thefarad and the faraday, after the British scientist Michael Faraday (1791-1867); thejoule, after the British scientist James P. Joule (1818-1889); thenewton, after the British scientist Sir Isaac Newton (1642-1727); theohm, after the German scientist Georg S. Ohm (1789-1854); thevolt, after the Italian scientist Count Alessandro Volta (1745-1827); and thewatt, after the British scientist James Watt (1736-1819). 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, 1881; coulomb, 1881; farad, 1861; faraday, 1904; joule, 1882; newton, 1904; ohm, 1870 (suggested in 1861); volt, 1873; and watt, 1882. 有人可能会问经过了多少位欧洲科学家才点亮了灯泡。如果我们以国际单位制或米—千克—秒单位制中各种单位之名称的形式来考虑的话，相当数量的人被包括了。这些单位按字母顺序排列是安培， 以法国科学家安德烈·马里耶·安培(1775—1836年）命名； 库仑， 以法国科学家夏尔·埃·德库仑(1736-1806年）命名； 法拉 和 法拉第， 以英国科学家迈克尔·法拉第(1791—1867年）命名； 焦耳 以英国科学家詹姆斯·皮·焦耳(1818—1889年）命名； 牛顿， 以英国科学家伊萨克·牛顿爵士(1642—1727年）命名； 欧姆， 以德国科学家格奥尔格·斯·欧姆(1789—1854年）命名； 伏特， 以意大利科学家亚历山德罗·沃尔塔伯爵(1745—1827年）命名； 瓦特， 以英国科学家詹姆士·瓦特(1736—1819年）命名。 定义诸如欧姆， “电阻单位，等于一伏特电压加于导体两端在导体内部产生一安培电流之导体电阻”， 当我们想到人们对电学做出的贡献是怎样在这之中得到纪念的时候，就带上了更多的人文内涵。英语中首次有记录的使用这些说法的时间如下：安培， 1881； 库仑， 1881； 法拉， 1861； 法拉第， 1904； 焦耳， 1882； 牛顿， 1904； 欧姆， 1870（在1861年建议使用）； 伏特， 1873；和 瓦特， 1882 〔ampere〕A unit of electric current in the meter-kilogram-second system. It is the steady current that when flowing in straight parallel wires of infinite length and negligible cross section, separated by a distance of one meter in free space, produces a force between the wires of 2 × 10-7 newtons per meter of length. 安培：米－千克－秒单位制中电流的单位，即在无限长且横截面极小的直流平行电线中流动的平稳电流，在自由空间中被一米长的距离隔开，在电线中间可产生每米2×10-7牛顿 〔ton〕A unit of weight equal to 2,000 pounds (0.907 metric ton or 907.18 kilograms). Also called net ton ,short ton 短吨：一个重量单位，等于二千磅(0.907公吨或907.18千克） 也作 net ton,short ton〔kilogram〕The base unit of mass in the International System, equal to 1,000 grams (2.2046 pounds). See table at measurement 千克：公制中质量的基本单位，等于1,000克（2.2046磅） 参见 measurement |
