| 1 | Adaptive Operator-Based Spectral Deconvolution With the Levenberg-Marquardt Algorithm显示文摘Spectral distortion often occurs in spectral data due to the influence of the bandpass function of the spectrometer.Spectral deconvolution is an effective restoration method to solve this problem.Based on the theory of the maximum posteriori estimation,this paper transforms the spectral deconvolution problem into a multi-parameter optimization problem,and a novel spectral deconvolution method is proposed on the basis of Levenberg-Marquardt algorithm.Furthermore,a spectral adaptive operator is added to the method,which improves the effect of the regularization term.The proposed methods,Richardson-Lucy(R-L)method and Huber-Markov spectroscopic semi-blind deconvolution(HMSBD)method,are employed to deconvolute the white light-emitting diode(LED)spectra with two different color temperatures,respectively.The correction errors,root mean square errors,noise suppression ability,and the computation speed of above methods are compared.The experimental results prove the superiority of the proposed algorithm. | Chan HUANG Feinan CHEN Yuyang CHANG Lin HAN Shuang Li Jin HONG | 2020 | Photonic Sensors2020，10，3： | 2 |

| 3 | Specific ion effects on soil aggregate stability and rainfall splash erosion显示文摘Soil interparticle forces can pose important effects on soil aggregate stability and rainfall splash erosion.Meanwhile,these interparticle forces are strongly influenced by specific ion effects.In this study,we applied three monovalent cations(Li^(+),Na^(+),and K^(+))with various concentrations to investigate the influence of specific ion effects on aggregate stability and splash erosion via pipette and rainfall simulation methods.The specific ion effects on soil interparticle forces were quantitatively evaluated by introducing cationic non-classical polarization.The results showed that aggregate stability and splash erosion had strong ion specificity.Aggregate breaking strength and splash erosion rate at the same salt concentration followed the sequence as Li^(+)>Na^(+)>K^(+).With decreasing salt concentration,the difference in aggregate breaking strength or splash erosion rate between different cation systems increased initially(1–10^(-2)mol L^(–1))and later was nearly invariable(10^(–2)–10^(–4)mol L^(–1)).The experimental results were well quantitatively explained by soil interparticle forces considering cationic non-classical polarization.Furthermore,both aggregate breaking strength and splash erosion rate of three cations revealed a strong positive linear relation with net force subjected to cationic non-classical polarization(R^(2)=0.81,R^(2)=0.81).These results demonstrated that different non-classical polarization of cations resulted in different soil interparticle forces,and thus led to differences in aggregate stability and splash erosion.Our study provides valuable information to deeply understand the mechanisms of rainfall splash erosion. | Jingfang Liu Feinan Hu Chenyang Xu Wei Du Zhenghong Yu Shiwei Zhao Fenli Zheng | 2022 | International Soil and Water Conservation Research2022，10，4： | 0 |
