摘　　要：计算了不同传压介质和加热筒变形对静态超高压腔中温度稳态分布的影响．稳态数值计算结果与近似解析公式结果及非稳态数值计算结果相符．由稳态最高加热温度对加热功率实验曲线斜率估算出叶蜡石的热导率与高压传热专门测量结果相符．Abstract The static and non steady distributions of temperature inside a high static pressure cell were calculated numerically by using the method provided by our previous work for different pressure media and heating elements. The results of numerical calculation for static and non steady distribution of temperatures are all agree with the approximate analytic results. The thermal conductivity of pyrophyllite obtained from the experimental slope of maximal value of the temperature versus heating power is in agree with the special thermal conductive experimental value.
