| 摘 要： | 通过对安装在宁波台ＺＫ０３ 井上的ＳＤ－ ３ 型自动测氡仪记录的１９９８ 年３ 月～８ 月整点值曲线图的分析，发现在距离该井８０ 多公里的嵊州等地先后发生的３－３ 级和４－５ 级地方震前，具有明显的、非常相似的临震前兆异常。主要特征为震前十几天开始出现整点测值向下突跳，数天后再出现频繁的整点测值向上突跳的形式，并以正异常为主。这是继该仪器在１９９６ 年长江口以东南黄海海域发生的ＭＳ６．１ 地震前记录到临震异常后，又记到的临震异常。笔者认为前兆数字观测仪器将在地震临震预报研究中发挥重要作用。

| Abstract: | The obvious and very similar anomalies before the earthquaks of M L3.3 and 4.5 occurred in Shengzhou and other counties have been discovered through the analysis for the integral hour value curve recorded by SD 3 autoradonometer mounted on Ningbo seismological station 03 well in Mar.～Aug. 1998. It is charater anomaly to behave abrupt decrease of integral hour values prior to the earthquakes over ten days, and after several days frequently abrupt increase. |
