一、问题的提出在制定压电加速度计检定规程中,我们曾对国内九个厂的产品进行了冲击标准试验,以确定幅值线性度。各研制单位分别采用了不同方法,由于对物理概念的理解不同以及数学方法各异,即使对同一组数据,各方法的最终结果可相差甚远。对于上述问题的认识不一,故 First, the issue put forward in the development of piezoelectric accelerometer verification procedures, we have nine domestic products on the impact of the standard test to determine the amplitude linearity. Different methods are adopted by each research and development unit. Due to the different understanding of the physical concepts and the different mathematical methods, the final results of the methods may be far different even for the same group of data. Different understanding of the above issues, therefore
