摘　　要：属性量-质转化关系或规律,可归结为一个定性映射(Qualitative Mapping,QM),它诱导出一个等价关系:E-R(QM)。在本文中,我们运用属性论中的定性映射方法来解决桥吊的状态监测问题。A kind of mathematical model of the relationship of conversion from a quantity (feature ) x to quality (feature) pi(o) of attribute a(o), called Qualitative Mapping(QM), is presented in the paper. An equivalent relationship E-R (QM), induced by QM, is also shown. So, in this thesis, Qualitative Mapping of Attribute Theory is employed to solve the problem of Status Detection for Derrick.
