Characteristic spectral features of the polarized fluorescence of human breast cancer in the wavelet domain
Florescence Spectroscopy Wavelet Transform Biomedical Optics Breast Cancer
2012/5/17
Wavelet transform of polarized fluorescence spectra of human breast tissues is found to localize spectral features that can reliably differentiate normal and malignant tissue types. The intensity diff...
Lattice QCD Study for Gluon Propagator and Gluon Spectral Function
Lattice QCD Study Gluon Propagator
2011/1/6
We study the gluon propagator in the Landau gauge in SU(3) lattice QCD at $\beta$=5.7, 5.8 and 6.0 at the quenched level. The Euclidean Landau-gauge gluon propagator $D(r)\equiv D_{\mu\mu}^{aa}(x)/24$...
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...
