spectral band ratio的意思|示意

In this paper we build chlorophyll-a models based on TM data, in which the traditional band ratio approach and mixing spectral analysis model were used.

由于经验模型的缺陷性，还提出了基于TM数据的水体混合光谱分析模型，同时分析了端元光谱提取方法对模型求解的影响。

The effects of pump ratio and fiber length arrangements on the output characteristics of the L-band SFS in terms of mean wavelength, spectral linewidth, and output power are analyzed.

分析了抽运比例以及光纤长度分配对光源的平均波长、光谱线宽和输出功率的影响。
