摘要：
The Lattice comparison measurements between crystals were improved and performed by the Self-Referenced Lattice Comparator (SRLC). The relative difference of lattice spacing for the samples cut from the same ingot (AVO28) was in good agreement with that calculated from the difference of their impurity concentrations. The relative difference of lattice spacing for the samples from the different ingots (AVO28 and Si28-23Pr11) was re-evaluated for checking the consistency in the realization of the kilogram.
