| 摘 要： | 仪器墩体受潮湿影响所产生的局部形变而引起的ZB磁变仪倾斜,是引起成都台CB3ZB变化幅度大,形成N字型年变化及其它类似形态变化的主要原因。实践证明,水泥墩湿引起的形变大,防潮效果差。而质地单纯均匀的石头墩受潮湿后引起的形变小,防潮效果好。

| Abstract: | The temperature and the moisture changes can affect the stability of a foundation of theinstrument of geomagnetic records.It is the cause of data changes observed by the geomagnetic instrument CB3ZB.The hard rock foundation is less affected bytemperature and moisture andis the better than the cement one for the geomagnetic observationin Chengdu Seismic Station. |

| Keywords: | geomagnetic base line Z-value changes affected by the moisture capillarity |
