摘要： 在分析实验室纵波幅度测量误差来源的基础上,实验考察了纵波声学换能器的相对位置(轴线偏移与旋转)对纵波幅度测量的影响,发现:旋转不会对纵波声速、幅度的测量产生影响;轴线偏移不会对纵波声速产生影响,但会对纵波幅度产生较大的影响。随后,提出了一套防偏装置,效果检验表明该装置的使用有利于提高纵波幅度测量的精度。
关键词: 纵波幅度, 测量精度, 轴线偏移, 旋转
Abstract: Based on the error analysis of P-wave amplitude measurement, the effect from the mutual positions(axis’s offset and rotation)of the sensors through the experiments was studied. The esult indicated that the rotation can hardly affect the P-wave velocity and amplitude. The axis’s offset can hardly affect P-wave velocity; however, it can affect P-wave amplitude. A set of device was put forward, which can enhance the measure precision of the P-wave amplitude.
Key words: P-wave amplitude, measurement precision, axis’s offset, rotation
