摘要
对表征频率稳定度的σy(τ)和σz(τ)方法进行了分析比较。以PSRB1 855+ 0 9计时观测得到的脉冲星时为例 ,用两种方法估计了其频率稳定度。计算结果和分析表明σz(τ)
y(τ)and σ z(τ)used for describing clock stability were analysed and compared with each other.A set of timing residuals of PSR B1855+09 was analysed with σ y(τ) method and σ z(τ) method respectively.Results indicate that σ z(τ) method is more suitable for pulsar stability study comparing with σ y(τ) method.
