摘　　要：测试平面的横向低频摇摆对惯性式横向振动传感器输出影响显著,实测中必须在全面分析响应信号特点的基础上,对这种影响予以掌握并在数据处理中采取相应措施。附带论述了横向振幅信号处理的专业性与复杂性,提出了处理建议。The lateral low-frequency oscillation of a tested plane has distinctive influence on the output of inertia lateral vibration transducers. In the process of testing, the influence of such kind must be well understood and corresponding measures must be taken in the data processing on the basis of all-round analysis of the response signal characteristics. By way of parenthesis, the specialty and complicity of processing of the lateral amplitude signals are also discussed and relevant advices are put forward.
