摘　　要：利用永磁体磁偏角测量的数学模型,建立磁偏角测量方法,根据实际测量数据,对引起磁偏角测量结果不确定度的各个因素进行逐项评定,最后得到磁偏角完整的测量结果。Measurement method for the deflected angle of magnetization of permanent magnet was developed basing on mathematic model. The uncertainties induced by each factor were evaluated according to measurement data. Finally full measurement results were obtained.
