2πα、2πβ粒子发射率副基准复现单位量值研究

摘要

针对2πα、2πβ粒子发射率副基准,进行了复现单位量值的研究.从该副基准复现单位量值的原理公式出发,对复现单位量值的主要修正项进行了综合分析,重点阐述了该副基准分辨时间和小能量漏计数的校正方法,最终实现了对该副基准复现单位置值.%Repetition unit value is researched for secondary standard of 2πα and 2πβ particle emission rate. Based on the principle of the repetition unit value for the secondary standard, the main correction for the repetition unit value is synthetically analyzed. The correction method of resolution time and small energy leakage of the secondary standard is elaborated. And then, repetition unit value for the secondary standard is realized.
