摘　　要：本文根据电阻率测深曲线的一维反演中对初始模型的要求和收敛速度。Choosing different primary models to invert a set of test resistivity sounding curves derived from a known model, according to the demands on primary models and convergent velocity, this paper compares singular value decomposition method with damping least square method.

关 键 词：奇异值分解法 阻尼最小二乘法 初始模型 测深
