spectral difference meaning in Chinese
光谱差
谱差
Examples
- Some evident spectral differences among three types of tissues were observed and their significance in the cancer spectroscopic diagnosis is discussed here
结果表明， 3种不同性质甲状腺组织的自体荧光光谱之间有着较明显的差异，这些光谱差异对于癌症的光谱诊断研究有一定的参考价值。 - 5 . analyze the spectral characteristics of typical object . process spectrum especially the vegetable spectrum with differential calculation , normalize processing and differential calculation after normalize processing , the spectral difference of the same object was removed
分析了光谱库中典型地物的光谱特性，对光谱库光谱特别是植被光谱做了导数、归?化及归?化后再计算导数等三种处理，消除了同一地物因背景、光照差异等因素造成的光谱差异。 - Because of modis predominant space and spectral differentiate rate , it ’ s has been broadly applied to various field , in the aspect of snow monitoring , modis has been successfully using a normalized difference snow index ( ndsi ) to provide global automated binary maps of snow cover . the ndsi is a spectral ratio that takes advantage of the spectral difference of snow in short - wave infrared and visible spectral bands , although it has higher precision , it can only discern one pixel to snow or other features , can not satisfy accurate drainage basin snow cover mapping and snow parameter extracting
Modis数据因其优越的空间分辨率、波谱分辨率,已被广泛的运用于各个领域,在积雪监测方面,已成功地运用归一化差分雪盖指数( ndsi )制作每天的全球雪盖分布图, ndsi是基于雪对可见光与近红外波段的反射特性和反射差相对大小的一种测量方法,然而它只能将一个像元辨别为积雪或非积雪,满足不了高精度应用要求。
