| 摘 要： | 建议在ＳＩ中,将“物质的量”改为“物质微粒量”,它的符号仍用ｎ,量纲仍为Ｎ。将“摩尔”改为“阿伏伽德罗”,它的符号用Ａｖ。阿伏伽德罗常数的定义修改为“０．０１２ｋｇ碳—１２的原子数目,或１Ａｖ物质微粒的数目”,它的符号采用ＮＡ,而不用Ｌ。

| Abstract: | This paper offers some proposals for the modifications of "mol" and so on in the SI system. The base quantity amount of substance may be changed into the "amount of particles of substance", but its symbol and dimension will remain as n and N, respectively. The symbol of unit "mol" may be changed into "Avogadro", and the shortened form of which is "Av". The definition of "Avogadro constant" is proposed to be rewritten as "the number of atoms contained in 0.012kg of carbon-12, or the number of particles of substance per Av". It is suggested that as the conventional symbol of Avogadro constant, for uniqueness, NA remains and L ought to be abrogated. |
