Abstract：
The momentum and polar angle depended position resolution and hit efficiency in each layer of BES(Ⅱ) muon detector are calibrated by using cosmic ray and hadron samples. Based on the calibration results, the efficiencies ratio function is constructed to separate μ/π effectively and applied in physics analysis.
