摘　　要：A new combination rule based on Dezert-Smarandache theory （DSmT） is proposed to deal with the conflict evidence resulting from the non-exhaustivity of the discernment frame. A two-dimensional measure factor in Dempster-Shafer theory （DST） is extended to DSmT to judge the conflict degree between evidence. The original DSmT combination rule or new DSmT combination rule can be selected for fusion according to this degree. Finally, some examples in simultaneous fault diagnosis of motor rotor are given to illustrate the effectiveness of the proposed combination rule.A new combination rule based on Dezert-Smarandache theory （DSmT） is proposed to deal with the conflict evidence resulting from the non-exhaustivity of the discernment frame.
