| 摘 要： | 本文在10-3-1.5×102 Hz频率范围内测定并讨论了我国九省十四个地区130余块硫化矿石和石墨化岩（矿）石标本的复阻抗振幅和相位的频率特性。并对其中80余块标本作了镜下岩矿鉴定分析工作。对每条实测的相位频率特性曲线按Cole-Cole模型通过电子计算机进行了拟合。分析讨论了影响各种岩（矿）石频率特性的主要因素,特别是导电矿物成分这个因素。弄清了一些规律,为今后在三维条件下进一步研究矿物成分的区分问题提供了重要的物性基础。

| Abstract: | More than 130 natural sulfide and graphite specimens were collected from different sul-fide deposits in 14 areas of 9 provinces in China. The amplitude and phase spectra of the impedances of the specimens were measured and analyzed within the frequency range of 10-3Hz to 1.5 Hz. Mineral identification and analysis were then made of more than 80 samples drawn from these specimens. By means of the computer, each phase spectral curve was then fitted according to the Cole-Cole model and the main factors affecting the character of the phase spectra were analyzed.In a great number of cases, it is not only the conductive mineral concentration and the texture-structure of ore-rocks that affect the frequency spectra, the conductive mineral components of those compact specimens of relativily high concentration also clearly affect the character of the spectra. Further more, if the component of the conductive minerals in different samples were the same, even if the texture-structures were different, the spectral characters of those compact ore samples exhibited very similar behaviour.This may provide an understanding of certain physical properties of minerals that can be considered as a basis for further research under three-dimensional conditions, on the differentiation of mineral components |
