After the continuum-removal, the reflectance is normalized to a range of 0-1.0. This enhances the soil absorption and reflection spectrum.
经包络线去除后的土壤光谱反射率归一化到0～1.0之间，可快速有效地突出土壤光谱曲线吸收和反射特性。

Soil water is the link of the continuum, which makes soil system, plant system and atmosphere system become a continuum by water absorption of root system and water evaporation of soil surface.
