1·Through long-term monitoring of the change of the chemical composition of groundwater, a new kind of premonitory information for earthquake prediction may be provided.
通过长期监测地下水中水化学成分的变化，就有可能为预测预报地震提供一种新的前兆信息。
2·So we suppose that the unusual behavior of animals is possibly a short-term macroscopic premonitory phenomenon of the earthquakes.
由此可见，动物的行为异常确是一种在临震前出现的宏观前兆现象。
3·The software RFPA is used to validate the relation between dilatation mutation and premonitory information of acoustic emission.
并采用RFPA软件验证了扩容突变与声发射前兆信息的关系。
