本文研究了周围环境成分对氧化铁矿物导电性长时张弛的影响,并对试验结果进行了模型分析,对阿尔及利亚菱铁矿物所进行的试验表明,导电性张弛特性是由于空气中的水气和氧气各种吸附形式的“吸附——解吸及扩散平衡”受到破坏所造成的。这种平衡之所以受到破坏,又是由于矿物在电性不相同的表面层受到焦耳加热所引起的。
In this paper, the influence of the surrounding environment on the long-time relaxation of the oxide of iron oxide minerals has been studied. The model analysis has been done on the experimental results. The tests on siderite in Algeria show that the electrical conductivity relaxation behavior is due to the water in the air Gas and oxygen in various forms of adsorption “adsorption - desorption and diffusion balance” caused by the destruction. This balance is destroyed, but also due to minerals in the electrical properties of the surface layer by Joule heating caused.
