| 摘 要： | 本文叙述继续过去已进行的工作1],对岩石标本在实验室内加压,观测其氡和钍的射气量.所用实验装置与过去基本相同. 实验结果仍说明地下水中氡含量的变化作为地震的一种前兆现象是与岩石破裂有关,但局部地区的破裂过程、岩性等有差异,可使地震前后氡含量异常变化呈现多种状态.

| Abstract: | This paper describes the continuation of the previous laboratory work1] on the observation of Radon and Thorium emanations from rock specimen under pressure. The equipments used in the experiment are nearly the same as before. The results show again the previous conclusion that the variation of radon content of underground water as a precursory phenomena of strong earthquakes is related to the fracturing of rock medium. However, for local regions, the characters of rock fracturing, of rocks themselves and so on are quite different so that the anomalous behavior of the variation of radon content before and after a strong earthquake may be quite different. |
