全空间视电阻率公式及全区求解方法是地下瞬变电磁理论的重要组成部分。为探讨全空间全区视电阻率求解方法，笔者将半空间全区视电阻率的平移算法引入至全空间并对其进行了研究。同时，分别采用理论数据、正演模拟数据及实测数据对该方法在全空间资料处理与解释中的有效性和精确性进行了分析。结果显示，平移算法与常规的全区视电阻率解法具有相同的理论基础，但前者避免了传统全区计算方法中的多解性；此外，采用由截距参数绘制的时间剖面图和视电阻率断面图进行联合解释产生了较好的应用效果。

Full-space apparent resistivity formulas and its all-time solution methods are important components in underground transient electromagnetic theory.For the purpose of exploring all-time apparent resistivity solving method in full-space medium, translation algorithm used to solve the problem in half-space was introduced and studied in full-space.Meanwhile,theoretical data,modeling data and measured data were adopted to analyze the validity and precision of translation algorithm in full-space data processing and interpretation. The results indicate that, translation algorithm and conventional all-time solving method have a same theoretical basis,but the former can acquire unique solution which other methods can not do.Furthermore,it achieves a good application effect to adopt the j oint interpretation with time cross section plotted by using intercept parameter and apparent resistivity section map.Therefore,translation algorithm used in data processing and interpretation of underground transient electromagnetic method can not only achieve satisfactory applicability and accuracy,but also posses a wider application prospect.
