植被和土壤的微波介电常数

The Microwave Dielectric Constant of Canopy and Soil

重点介绍了植物材料介电常数的Ｄｅｂｙｅ－Ｃｏｌｅ双频散模型及土壤物理模型的建立。应用这些模型与实验结果比较表明，模型计算值与测量值有较好的一致性。给出了模型计算公式以及与计算值相比较的测量结果。实验证明模型和数据在应用中是可靠的。

This paper lay emphasis on establishing a Debye-Cole dual-dispersion dielectricconstant model for vegetation materials and a physical model for soil.Compared with mea-surements,the proposed dielectric models are found to agree well with the data. Also ,theexpression for these models and the graphical data are presented.It had been proved thesemodels and data are reliable in application.
