摘　　要：推导了考虑连接弹簧质量的非保守耦合系统的功率流表达式。理论分析表明:耦合质量对非保守耦合系统功率流特性有重要的影响。耦合质量越大,耦合损耗也越大,当m3>k12+k3k3m1时,必须考虑耦合质量对损耗功率流的影响。The formulae of power flow in non-conservatively coupled oscillators with spring mass taken into consideration have been derived. Theoretical analysis indicates that coupling mass has important influence on power flow charateristics of non-conservatively coupled systems. The larger coupling mass is, the larger coupling loss is. When m3〉2k3/k1＋k3m1, the influence of c ,upling mass on power flow loss should be considered.

关 键 词：耦合质量 损耗功率流
