此文原载美国《科学》(SCIENCE)207卷第4433号.文中介绍了震前水氧前兆效应的一个较为可信的实例,并对水氧观测点的选择提出了有益的经验.作者认为地下水氧含量的异常作为趋势性和临震的前兆仍是可信的,但并未提出把类似的异常作为预报地震的依据,而认为是用以研究的一项资料累积工作,这种态度似值得注意. This article was originally published in Science Volume 207, No. 4433. A more credible example of the precursor effect of water oxygen before the earthquake is presented in this paper, and some useful experiences are suggested for the selection of water and oxygen observation points The abnormality of groundwater oxygen content is still credible as a precursor of trend and impending earthquake. However, it does not suggest that similar anomalies should be used as the basis for earthquake prediction, and is regarded as a data accumulating work to be studied. This attitude may seem like Worth noting.
