1) Proportion of shared DNA frag-ments
等长片段比值
2) three-band photographic ratio method
三波段相片比值法
3) band ratio
波段比值
1.
Though band ratio is highly evaluated as a single method in oil-gas exploration,the effect is far from satisfactory.
在基于单一方法进行油气勘探的过程中,前人对波段比值的方法给了很高的评价,但效果均不显著。
2.
However,the rock texture can be enhanced by selecting band ratio and by using composite negative processing method based on DN value analysis of diff.
本文从统计、研究雪和岩石光谱特征曲线入手，结合研究区积雪对不同ＴＭ波段图像中地形响应的漫反射统计分析特点，采取波段比值＋假彩色合成图像求反处理的方法，有效地突出了不同岩性的纹理信息，达到了区分岩类的目的。
3.
With the MODIS data from 2001 to 2005,areas of the tidal flats in the coastal zone of Fujian Province in China are calculated utilizing the band ratio of MODIS 250 m resolution of visible and near infrared band to high tidal level and low tidal level,and the results are verified by the 30 m resolution Landsat-7/ETM+ satellite image of the Luoyuan Bay and the Fuqing Bay.
以2001~2005年MODIS数据为信息源,每年选取高潮位和低潮位两个时相的MODIS数据,根据滩涂对MODIS 250 m分辨率可见光和近红外探测波数的光谱反应特性,采用波段比值算法来监测福建省海岸带的滩涂面积,并对监测结果用罗源湾和福清湾30 m分辨率的Landsat-7/ETM+影像进行验证分析,结果表明,MODIS数据的观测时间与海洋高低潮位时刻比较接近,便于对滩涂资源的遥感监测。
