摘　　要：本文基于半导体矿物热电特性的基本理论,通过大量科学研究成果之间客观联系的分析,论证了天然半导体矿物热电特性与地震预测的关系。结果表明,地壳内广泛存在天然半导体矿物,且绝大多数天然半导体矿物具有热电特性。孕震过程产生梯度热场时,会激发周围热电介质产生热电势,热电势的积累对孕震区电场具有一定的干扰效应,这种干扰效应可作为地震预测的信息源之一。另外,从成矿带和地震带之间的空间关系分析,可以认为天然半导体矿物的集中分布与地震活动带相一致。上述结论对深刻理解地震地电异常机理有重要的意义。On the basis of theories of theromelectricity of semi-conductor minerals and summarizing connections among many prior literature studies, this paper discussed the relationship between theromelectricity of semi-conductor minerals and earthquake prediction. This paper believed： there are many semi-conductor minerals in the earth crust, and most of them have distinct theromelectrical property; when there is a gradient heat field generated by seism, theromeleetrical potential of semi-conductor minerals will be aroused, and such theromelectrieal potential will disturb the earth electric field. This kind of interference can be read as information for earthquake prediction. In addition, the spatial distribution relations of ore zones and seism zones showed that the distribution of natural semi-conductor minerals enriched zones is consistent with that of seism zones. Results of this study are important for understanding the mechanisms of thermoeleetricity anomaly during earthquakes.
