am·pere AHD[ămʹpîr'] D.J.[ˈæmˌpɪə]K.K.[ˈæmˌpɪr]n.（名词）abbr. A【缩写】- 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
- A unit in the International System specified as one International coulomb per second and equal to 0.999835 ampere. See table at measurement 安培：一种国际系统单位，指每秒中流过一国际标准库仑的电量，相当于0.999835安培 参见 measurement
- After André Marie Ampère 源自 安德鲁·玛丽 Ampère
