油菜氮素光谱定量分析中水分胁迫与光照影响及修正 Effect and Correction of Water Stress and Lighting Factor on Rape Nitrogen Content Spectral Analysis
油菜 含氮量 光照 水分胁迫
2009/5/18
研究了油菜氮素和水分胁迫在光谱检测中的相互作用，以及光照的变化对作物光谱检测的影响。为了克服光照因素对光谱检测的影响，针对氮素和水分的特征波长分别建立了基于光谱反射率变化率的光照修正模型；为了实现对氮素和水分相互作用的解耦，针对不同含水率水平的植株分别建立了全氮含量光谱特征的主成分回归模型。利用氮素光谱组合分析模型对植株全氮含量进行预测，结果表明，实测值与预测值的相关系数R为0.92，均方根误（R...
Spectral Analysis of the Background in Ground-based Long-slit Spectroscopy
Atmospheric effects planetary nebulae:general planetary nebulae:individual (HD 44179, NGC 2022, NGC 6309, NGC 6891)
2009/5/12
This paper examines the variations, because of atmospheric
extinction, of broad-band visible spectra, obtained from long-slit spectroscopy,
in the vicinity of some stars, nebulae, and one faint gala...
Crustal Thermal Properties of the Central Pontides (Northern Turkey) Deduced from Spectral Analysis of Magnetic Data
heat flow Curie point depth spectral analysis Central Pontides
2010/1/11
The Pontides can be divided tectonically into three main sectors: Eastern, Central, and Western Pontides. Each of these represents an amalgamated tectonic mosaic consisting of remnants of oceanic, con...
Detection of directivity in seismic site response from microtremor spectral analysis
seismic site microtremor spectral analysis
2009/12/30
Recent observations have shown that slope response to seismic shaking can be characterised by directional variations of a factor of 2–3 or larger, with maxima oriented along local topography features ...
