摘要:
以德拜模型为基础，分析了不同电磁测量频率下土壤质地对土壤水分介电测量的影响规律，确定了不同误差要求下的土壤水分介电测量频率上限值，可作为进一步研制适用面较广的土壤水分测定仪的基础。
Abstract:
Based on the Debye model, the influence of electromagnetic frequency on soil dielectric constant(εs) is analyzed, and the maximum electromagnetic frequency in the different measurement variation of soil moisture dielectric measurement is decided.
