After improvement, the spectral area is equal to 1, the values of spectrum and slope are continuance on the sectioned point.
经过改进后可使谱面积等于1,且在分段处谱值及斜率均连续。

The experiment shows although sea water and oil spill have low spectral reflection values, but in 300 to 500 nm spectral region, they have larger contrast.
