根据符合测量原理,利用数理统计方法,系统地推导并综于了4πβ-γ符合测量中数据处理及其不确定度的估计方法,以Algol-60和Fortran语言编制了计算程序。它克服了一般计算方法的某些缺点,减小了计算误差,具有严格、系统、完整、快速和效率高等优点。可以 广泛地应用于不同衰变类型核素活度的计算及其不确定度估计。 According to the principle of coincidence measurement, the method of data processing and its uncertainty estimation in 4πβ-γ coincidence measurement was systematically deduced and analyzed by using mathematical statistics method. The calculation program was compiled by Algol-60 and Fortran language. It overcomes some shortcomings of the general calculation method, reduces the calculation error, has the advantages of strict, systematic, complete, fast and high efficiency. It can be widely used in the calculation of nuclide activity of different decay types and estimation of its uncertainty.
