These matrices may also be used to transform RGB colors, to scale RGB colors, and to control hue, saturation and contrast.
这些矩阵也可用于转换rgb颜色，规模RGB颜色，并控制色调，饱和度和对比度。

A spatially-random network model by using measured pore morphology was then set up to simulate the pore scale flow processes, and to predict the soil water retention curve near saturation.
On the macroscopic scale, the elastic modulus and the plastic parameters for both pore collapse and plastic shearing processes are expressed as functions of water saturation degree.
