摘　　要：Petro－Sonde或称为岩性探测技术，其实质是接收时间域内电磁场中不稳定的脉动噪声。因此，其观测数据既无重复性、一致性，又无稳定性，不可能用它来了解地下的地质结构。本文从理论上对该方法的分辨率、穿透深度、目的层深度标定、时间域电磁信号的读数等问题进行了分析，又从实际数据的采集不合理性及解释中存在的主观随意性，提出了证据。最后认为该方法是不科学的，不可取的。Petro-Sonde technique (or lithology probing technique) actually receives unsta-ble pulsed noises in time-domain electromagnetic fiekd. Its observed data are nonre-peated, inconsistent and unstable; therefore, they can not be used to investigate subsurface geologica1 structure. This technique is analysed theoretically in resolu-tion, penetrating depth, target layer determination, the readings of time-domain electromagnetic signals and so on. I offer the full evidences of unreasonable data ac-quisition and voluntary data interpretation. I think the technique is unscientific and unavaila ble.
