    利用电子对事例对北京谱仪Ⅲ飞行时间的测量误差,以及不同测量之间的关联因子随击中位置的变化进行了仔细的研究.加权的飞行时间由不同的测量值及其相关的误差矩阵计算而得.蒙特卡罗研究表明.为北京谱仪Ⅲ开发的关联分析算法可以正确地处理包含公有误差项的多个实验测量结果的合并,并且能够为粒子鉴别提供可靠的飞行时间信息.

    The errors and correlations of BESⅢ TOF measurements are carefully checked in hit position at z partitions with the electron-pair events. The measured time-of-flight's and their covariance matrices are subjected to a correlation analysis algorithm which is developed for BESⅢ to combine the independent measurements with common errors. Monte Carlo studies show that the correlated analysis can provide more reliable TOF information on particle identification.
