摘要
垂直摆倾斜仪与水平摆倾斜仪虽然记录的是同一物理量,但二者的异常图像差别很大。笔者将造成垂直摆异常图像的因素分为四个方面:(1)人为因素;(2)仪器本身造成的;(3)与地震有关的;(4)与不良台址有关的。对记录曲线的异常图像的认识是一件很有意义的事情。
though perpendicular pendulum and horizontal pendulum record the same physical quantity,but the difference in anomaly image is very large.There are four factors to cause anomaly for perpendicular pendulum:(1)anthropogenic factor;(2)instrumental factor;(3)seismic factor;(4)bad location of station factor.It is significant to recognize anomaly from the recorded curves.
