摘要：

Significant improvements in the method for determining the absolute molar mass of silicon have been achieved and are reported. They have led to a reduction in the uncertainty of the molar mass and hence in its contribution to the uncertainty of a previously published Avogadro constant N-A. The new value for N-A is almost unchanged at 6.022 136 5x10(23) mol(-1) but the uncertainty is reduced to 0.000005 1 x N-A.
