【摘要】：正一个精准的量子电流源已被设计,用于根据即将重新定义的国际单位制定标电流。计量工作者的本性是保守的,他们知道,一个新测量标准的草率采用可能导致科学和商业领域的混乱。因此,国际单位制(SI)自1960年诞生以来,正在经历的第一次重大修订,是一件大事。两年以后,在巴黎的度量衡大会上,官员们将采用一种新的国际单位制,其中每个单位都可以从几个基本常数的固定值中获得。目前,所有的目光都
[Abstract]:A precise quantum current source has been designed to set the standard current based on the international unit to be redefined. The nature of metering workers is conservative, they know, The hasty adoption of a new standard of measurement could lead to confusion in the scientific and commercial realms. Thus, the first major revision of the International system of Units (SISI) since its birth in 1960 is a major event. Two years later, At the Paris Congress, officials will adopt a new system of international units in which each unit can be obtained from a fixed value of several fundamental constants. For now, all eyes are set
