摘　　要：本文在研究和分析环境因子对断层测量年周变和季节性变化影响的基础上,归纳出断层形变测量年周变的变化规律。并针对不等周期观测资料,建立了形变测量的准线性动态数学模型。 最后,对门源地震有异常的扁都口资料用上述模型进行了处理。结果是比较满意的。Based on analysing the effects of the environmental factors ( as e.g.the ground and atmospheic temperatures and frozen earth ef-fects)on the yearly periodic and seasonal variation in the cross-fault deformation measurements, the pattern, range and the law of the anniversary change are obtained. and quasi-linear dynamic mechanical model for non-periodic observations is also established as follows. Y ( t ) =A + Bt + C * Sin ( 30T ) +D * QT +△( t ) Finally, The precursonr data of Bian Dokou in Menyuan earthquake is calculated by this method and the result is satisfactory.
