摘　　要：将归一化总梯度数据处理技术运用于中间梯度剖面视极化率观测数据的延拓处理,研制了一套实用的中梯激电数据解释软件系统。实验数据与野外数据的处理结果表明,在选择合理的计算参数基础上,归一化总梯度能给出激电异常较为可靠的解释。The normalized total gradient technique （NTG） was employed in the interpretation of induced polarization （IP） with the purpose of obtaining the space information on IP sources. A program package based on the NTG theory was also developed to process IP data along a profile. The results from experiments and field work show that the NTG method can generate a reliable section of IP source distribution with correct continuation parameters.
