将气相色谱-负离子化学电离质谱法(GC-NC I-M S)应用于蔬菜水果中9种有机磷农药残留的分析测定,初步解析了这些农药的NC I-M S特征阴离子结构和断裂机理,并初步探讨了GC-NC I-M S分析蔬菜水果中有机磷农药残留时基体效应的影响。采用空白样品基体匹配校准曲线法(M C)进行定量分析,有效地降低了基体效应的影响。蔬菜水果样品用乙酸乙酯超声提取,以乙硫磷为内标物,采用GC-NC I-M S的选择离子监测方式(S IM)进行定性和定量分析。9种有机磷农药的方法检测限为0.12~1.0μg/kg。在方法的检测限与1 000μg/kg范围内,线性相关系数都大于0.999 3。当空白蔬菜水果(西红柿)样品的加标水平为100,400,800μg/kg时,平均加标回收率为78%~126%,相对标准偏差为0.58%~14.7%。An analytical method of gas chromatography coupled with negative ion chemical ionization-mass spectrometry for simultaneous determination of nine organophosphorus pesticide residues in vegetables and fruit has been developed,and the negative ions structure and partition mechanism of the nine organophosphorus pesticides were interpreted.Meanwhile,the matrix effect for sample analysis was discussed,and matrix-matched calibration for quantification was introduced to reduce the matrix effect in this method.Pesticides were extracted from sample with ethyl acetate in an ultrasonic bath,then determined by gas chromatography-mass spectrometry operated in negative chemical ionization mode and quantified in selective ion monitoring mode,and ethion was used as an internal standard.The detection limits of the method were 0.12-1.0 μg/kg for the nine organophosphorus pesticides,and the relative coefficients were higher than(0.9993).A blank sample(tomato) was spiked at 100,400,800 μg/kg for each pesticide,and the recoveries were determined to be from 78% to 126% with relative standard deviations from 0.58% to 14.7% for the pesticides

Underwater Image Restoration Based on Background Light Estimation

针对水下图像颜色失真与模糊问题,提出了基于背景光估计与透射率优化的水下图像复原算法。该算法将透射率定义为直接分量透射率和后向散射分量透射率,有效提升了成像模型的完整性。首先,对红色衰减分量进行补偿并重置直方图分布范围实现色彩均衡;其次,基于亮度、梯度判别及色调判断选出最佳背景光点;然后,通过红色暗通道先验得到后向散射分量透射率,利用无退化像素点求得直接分量透射率;最后,将两个透射率及所求背景光代入成像模型获得复原图像。实验结果表明,该算法能够有效平衡图像的色度、饱和度及清晰度,视觉效果接近自然场景下的图像。</p
