Microwave remote sensing is a very suitable instrument for soilmoisture monitoring because of its sensitivity to the dielectric constant of soil which is dominated by soil moisture.
微波遥感由于其穿透性以及对水分的敏感性而非常适于进行土壤水分观测。

When pressure is kept constant, the relationship between the magnitude of soil expansion and shrinkage deformations and the moisture movement appears linear.
