Abstract： The outmost subsystem of Beijing spectrometer（BES）, Muon counter was composed of 978 international advanced resistive plate counters (RPCs). Thus, the properties of those RPCs determined the function of Muon counter directly. The authors studied three important parameters of each RPC and tried to improve the physical characteristics through these parameters. Influence of resistive plate surface finish degree on RPC function was analyzed, at the same time the results were illustrated by figures. The above indicates that the counter has good performance and good prospects.
Key words： RPC; BES-III; MUON; Counter; Function
