【摘要】 介绍了植物体内生物电位的形成机理，国内对生物电刺激的实验室研究成果与合欢树地震观测的震例对比情况，分析了合欢树电位异常变化的影响因素及其与地震前兆的相关性。指出利用合欢树的异常变化可以预测地震的发生，但由于植物体内的生物电影响因素多、机理复杂，在地震预报中要结合其他观测项目综合分析判定其异常。更多还原

【Abstract】 The formation mechanism of bioelectric potential in the body of plants ,the rese arch results of bioelectric activation in domestic laborato ries ,and earthquakes of observation of silk tree are introduced . The influencing factors of anomalou s variety of bioelectric potential and the relation with earthquakes are analyze d . Using the anomalous variety of bioelectric potential of silk tree ,earthquake may be predicted , because there are many complicated influencing factors of bie lectric potentialin the body of plant,the judgement of earthquake precursor sh ould synthesize other ob servation item in the earthquake prediction .更多还原
