摘要
黄铁矿单晶在具有一定的温度差时就产生温差电动势，呈现出四种导电类型，即p型，n-p型，p-n型和n型。不同的导电类型与它形成时的物化环境关系密切。决定黄铁矿导电类型的基本物化条件有三个。测定黄铁矿的温差电动势，将其除以两测量电极间的温度差，就得到黄铁矿的热电系数。不同类型的矿床，其黄铁矿热电系数的空间分布状态不同。利用黄铁矿的热电性可以预测隐伏矿体，研究成矿的分带性，评价矿床的剥蚀水平等。

When there exists certain temperature difference, the single crystal of
pyrite will produce thermo-electrotrmotive force and assume four conduction
types, i.e., p type, n-p type, p-n type and n type. Different conduction types
are closely related to physicochemical environments during the formation of
pyrite. There are three basic physicochemical factors that decide the condu-
ction type of pyrite. Determine the thermo-electromotive force of pyrite, and
divide it by temperature difference between the two electrodes, we can get
thermoelectric coefficient of pyrite. In different types of ore deposits, spatial
distributions of thermoelectric coefficients of pyrite are different. The thermo-
electricity of pyrite might be used to predict concealed ore bodies, study
metallogenic zonality and evaluate denudation extent of ore deposits.
