| 摘 要： | 本文就使用同轴测量线装置用反射法测量岩石介电常数的一些问题进行了讨论。为了求得岩石的介电常数和耗损角,需要根据测量数据求解超越方程。文中提出三种求解超越方程的数值解法,并指出各种解法的优缺点,将这三种数值解法结合使用效果较好。文章还对测量误差进行了分析,提出了考虑测量误差的计算公式,对影响测量结果的主要因素进行了讨论,并提出了使用反射法测量岩石介电常数的适用范围。

| Abstract: | In this paper, the dielectric constant measurements of rocks with a reflective method are discussed. It is necessary for evaluating dielectric constant of rocks to find the solution of a transcendental equation. Three numerical methods of a equation are presented. It shows that the combination of the three methods is suitable for different cases, especially for the measurement of several points in a frequence range. The measurement errors have been analyzed and the calculating formulas are also given in this paper. The main factors affecting on the results of measurements and the suitable range of measuring dielectric constant of rocks with reflective method are proposed. |
