| 摘 要： | 采用浸渍法测定了具有不同石墨化率自焙炭块的体积密度和量气孔率,并与其它炭块进行了比较,结果表明：在实验温度范围内体积密度和显气孔率基本不随温度变化;在恒温时间内,二者基本与恒温时间无关,据实验结果,讨论了不同条件下自焙炭块的电阻率与温度和时间的关系。

| Abstract: | Apparent porosity P a and bulk density D b of self baking carbon block were determined by using a water absorption. It is concluded that P a and D b are basically independent of the self baking temperature and time under the experimental conditions. A dependence of resistivity of the carbon block on temperature and time was discussed on the basis of the experimental results. |
