电阻率异常提取 英文

电阻率异常提取英文
English:
Extracting abnormal resistivity values is a crucial task in geophysical surveys as it can indicate the presence of subsurface anomalies such as mineral deposits, groundwater, or environmental contamination. There are several methods to detect and extract abnormal resistivity values from geophysical data, including statistical analysis, visual inspection, and anomaly detection algorithms. Statistical analysis involves calculating the mean and standard deviation of the resistivity values and identifying values that fall outside a certain range. Visual inspection relies on examining the data graphically to identify any outliers or anomalies. Anomaly detection algorithms, such as clustering or machine learning techniques, can automatically identify abnormal resistivity values based on patterns in the data. Once abnormal values are extracted, further analysis can be conducted to determine the cause of these anomalies and their significance in the context of the survey area.

提取异常电阻率数值在地球物理勘测中是一项至关重要的任务，因为它可以指示地下异常的存在，比如矿藏、地下水或环境污染。

有几种方法可以检测和提取地球物理数据中的异常电阻率数值，包括统计分析、视觉检查和异常检测算法。

统计分析涉及计算电阻率数值的均值和标准偏差，并识别超出特定范围的数值。

视觉检查依赖于对数据进行图形化检查，以识别任何异常值或异常值。

异常检测算法，比如聚类或机器学习技术，可以根据数据中的模式自动识别异常电阻率数值。

一旦异常数值被提取出来，可以进行进一步的分析，以确定这些异常的原因以及它们在勘测区域背景下的重要性。
