阿伏伽德罗常数N_A在SI中的作用

Function of avogadra constant N_A in SI

这篇论文简要说明了用硅原子质量取代人工制品的原子路径。不仅分析了当前的状况 ,阿伏伽德罗常数NA 的相对不稳定性高于 5× 10 - 8,同时提出了改善的方法。利用非常精密的测定 ,可以使克分子质量和密度测定方向的相对不稳定性降至 10 - 7。

This article simply illuminates the atomic path tha t use the quality o f silicon atom to replace manual produce. Not only analyses the current status , the relative instability of Avogadra Constant N A beyond 5×10 -8, but also bri ng forward the method to improve. Use very precision mensuration, the relative instability of mol quality and density mensuration reduce to 10 -7.
