论文摘要
依赖频率土壤特性的现场测量的现有方法需要大量时间，这使得难以获得新的实验数据并进一步研究电土壤特性。但是，通过可访问的电子组件组装的相对简单的测量设备几乎可以使测量与常规低频电阻率一样容易。本文介绍了此类设备的详细描述：描述包括功能方案，计算算法中心部分的伪座，使用的电子组件和设备的工作原理。本文讨论了设备所选参数背后的原因（例如测量电路之间的隔离，生成的信号波形，电极阵列的使用），并解决了测量的其他可能方法。本文还提供了几个测量结果，并与特定电极阵列配置的计算结果进行了比较。最后，工作描述了影响测量结果准确性的基本方面。
Existing approaches for the field measurements of the frequency-dependent soil properties take a significant amount of time, making it difficult to obtain new experimental data and study the electrical soil properties further. However, a relatively uncomplicated measurement device assembled from accessible electronic components can make the measurements almost as easy as those for the regular low-frequency resistivity. The article presents a detailed description of such a device: the description includes the functional scheme, pseudocodes for central parts of the calculation algorithm, used electronic components, and working principle of the device. The article discusses the reasons behind the chosen parameters of the device (such as isolation between the measurement circuits, generated signal waveform, usage of the electrode arrays) and addresses other possible approaches for the measurements. The paper also provides several measurement results and a comparison with a calculation result for a particular electrode array configuration. Finally, the work describes essential aspects affecting the accuracy of measurement results.
