摘　　要：研究了微波场中矿物及其化合物的升温特性，并对其升温曲线进行了定量描述，旨在为探求冶金新工艺提供理论依据。结果表明，矿物在微波场中的升温速率取决于其自身特性以及对微波的吸收性，其升温速率方程可表达为：Ｔ＝ａｔ＋ｂ（第一阶段）和Ｔ＝（ｃｔ＋ｄ）１／２（第二阶段）。The characteristics of temperature inerease of minerals and compounds in the microwave field were inves-tigated and the curve of temperature increase was described quantiatively, aimed at exploring newly theoretical foundation many nonferrous metallurgical methods of nonferrous metals. The results showed that, temperature increasing rate of many nonferrous metals minerals in microwave field is mainly dependent upon their own characteristics and adsorptivity to microwave. In addition, their temperature increasing rate equations were derived as follows:T=at+b(first stage) and T=(ct+d) 1/2 (second stage).
