| 1 | Practical implementation of Hilbert-Huang Transform algorithm显示文摘Hilbert-Huang Transform (HHT) is a newly developed powerful method for nonlinearand non-stationary time series analysis. The empirical mode decomposition is the key part of HHT,while its algorithm was protected by NASA as a US patent, which limits the wide application among thescientific community. Two approaches, mirror periodic and extrema extending methods, have been de-veloped for handling the end effects of empirical mode decomposition. The implementation of the HHT isrealized in detail to widen the application. The detailed comparison of the results from two methods withthat from Huang et al. (1998, 1999), and the comparison between two methods are presented. Gener-ally, both methods reproduce faithful results as those of Huang et al. For mirror periodic method(MPM), the data are extended once forever. Ideally, it is a way for handling the end effects of theHHT, especially for the signal that has symmetric waveform. The extrema extending method (EEM)behaves as good as MPM, and it is better than MPM for the signal that has strong asymmetric wave-form. However, it has to perform extrema envelope extending in every shifting process. | 黄大吉 赵进平 苏纪兰 | 2003 | Acta Oceanologica Sinica2003，22，1： | 34 |
| 2 | Preparation and Properties of a New Composite of Epoxy Emulsion (EEM) Modified Cement显示文摘High performance cement based composite materials was prepared by adding epoxy emulsion. The epoxy emulsion was synthesized with epoxy phosphoric acid ester and poly-glycol in laboratory. This epoxy emulsion has advantages over other emulsion, such as dehydrated slightly, and well film formation abilities. The mechanical properties, corruptness resistance and structure of ep-oxy emulsion modified cement mortars were studied. Experimental results show that the mechanical properties of modified cement mortars are slightly increased with increasing epoxy emulsion content, especially the flexure strength. The corruptness resistance of all modified mortars is better than the unmodified mortar. The polymer film forms the bridge phases between the matrix and the aggregate regions, and forms a three-dimension structure in the cement hydration system , which improves the mechanical properties of modified mortars. | 肖力光 | 2009 | Journal of Wuhan University of Technology(Materials Science)2009，24，5： | 10 |
| 3 | Characterization of chromophoric dissolved organic matter(CDOM) in the East China Sea in autumn using excitationemission matrix(EEM) fluorescence and parallel factor analysis(PARAFAC)显示文摘Samples of chromophoric dissolved organic matter(CDOM)in the East China Sea in autumn(October in 2011)were analyzed by excitation emission matrix(EEM)fluorescence spectroscopy combined with parallel factor analysis(PARAFAC).Three terrestrial humic-like components(C1,C2 and C3)and one protein-like component(C4)were identified.Based on spatial distributions,as well as relationships with salinity,the following assignments were made.The three humic-like components(C1,C2 and C3)showed conservative mixing behavior and came mainly from riverine input.The protein-like component(C4)was considered a combination of autochthonous production and terrestrial inputs and a biologically labile component.Path analysis of samples from the middle and bottom layers revealed that the causal effects on C1 were 78.46%for salinity,and 21.54%for apparent oxygen utilization(AOU);those on C2 were 76.43%for salinity,and 23.57%for AOU;those on C3 were70.49%for salinity,7.01%for Chl-a,and 22.50%for AOU;those on C4 were 55.54%for salinity,14.6%for Chl-a,and29.86%for AOU in middle layer;and those on C4 were 57.37%for salinity,29.02%for Chl-a,and 13.61%for AOU in bottom layer.Results indicated that CDOM in the East China Sea was mainly affected by terrestrial inputs,and microbial activities also played a key role in biogeochemical processes of CDOM.The application of the EEM-PARAFAC model presented a unique opportunity to observe compositional changes in CDOM in the East China Sea.In addition,the humification index(HIX)suggested that CDOM from the East China Sea was less stable and stayed shorter in the environment. | BAI Ying SU RongGuo YAN LiHong YAO Peng SHI XiaoYong WANG XiuLin | 2013 | Science China Chemistry2013，56，12： | 3 |

| 6 | Interaction of Ca^(2+) and soil humic acid characterized by a joint experimental platform of potentiometric titration, UV–visible spectroscopy, and fluorescence spectroscopy显示文摘Rocky desertification has become a major environmental issue in the karst region of southwestern China.Karst rocky desertification was more severe in regions of limestone soil than in adjacent regions of other soils,despite the relatively higher soil organic matter(SOM)content in limestone soil.The underlying mechanism remains ambiguous.We speculated that the geochemical characteristics of limestone soils in the karst region plays an essential role,especially the high calcium content of limestone soil.To test this hypothesis,we collected limestone soil samples from a limestone soil profile in the southwestern China karst region and extracted humic acid(HA)from these limestone soil samples.We investigated the interaction of Ca^(2+)and three HA samples on a joint experimental platform,which consists of an automatic potentiometric titrator,a UV–visible spectrometer,and a Fluorescence spectrometer.HA solutions were titrated by Ca^(2+)and optical spectra of the HA solutions were monitored during the titration experiments.The results indicated that:(1)the interaction of Ca^(2+)and HA is a combined process of adsorption and complexation.Adsorption dominated the overall distribution behavior of Ca^(2+),which could be fit by Langmuir and Freundlich isotherm models.Complexation was distinguished only when the concentration of Ca2+is low;(2)the changes of UV–visible spectroscopy and excitation–emission matrix fluorescencespectroscopy spectra of HA samples when they were binding with Ca^(2+)implied the apparent molecular size and structure of HA became larger and more complex;(3)the combination of Ca^(2+)and HA plays an important role in the SOM preservation of limestone soils but the stability of the Ca–HA association was relatively weak.The present study draws attention to maintaining the relatively higher Ca^(2+)concentration in limestone soils in ecologic restoration attempts in karst regions. | Haiming Tang Baohua Xiao Peiwen Xiao | 2021 | Acta Geochimica2021，40，3： | 1 |
| 7 | 纳米氧化锌对厌氧污泥中微生物内源代谢产物和膜污染性能的影响显示文摘从厌氧污泥的角度,探究ZnO-NPs对微生物内源代谢产物(BAP)产量和膜污染性能的影响。在实验室培养的厌氧污泥中投加不同浓度的ZnO-NP,通过序批式实验和过滤实验,分别考察ZnO-NP作用下BAP的产量和膜污染性能的变化规律。发现在ZnO-NPs的短期暴露下,BAP和胞外聚合物(EPS)的总量都随着ZnO-NPs浓度的增加而增加。当ZnO-NPs浓度为300 mg·L^(-1)时,BAP和EPS的7 d总产量相较于空白对照组,增幅分别为303.4%和112%,远远高于其他实验组。过滤实验发现,随着ZnO-NPs的增加,BAP的膜污染性能不断增加。此外,通过扫描电镜(SEM)和三维荧光光谱(EEM)分别对污泥形态和BAP特性进行研究,发现在ZnO-NPs短期暴露下,ZnO-NPs的浓度越高,其对厌氧污泥的形态和BAP特性影响越大。 | 胡勤政 王成燚 汪跃 陈琳 | 2018 | 环境工程学报2018，12，6： | 1 |

| 11 | 盐积累胁迫下厌氧正渗透MBR混合液性质的响应特性显示文摘厌氧正渗透膜生物反应器(AnOMBR)是一种将正渗透膜过程与厌氧生物处理结合的新型污水处理技术,近年来备受关注。然而盐积累是其面临的主要挑战。为此,本研究考察AnOMBR在高盐度的冲击下污泥混合液性质的变化情况。结果表明,反应器运行7 d后,盐积累现象严重,电导率上升到接32 mS/cm,导致初始水通量从14 L/(m^(2)·h)降至3 L/(m^(2)·h)。反应器对TOC和TP的去除效果较好,但氨氮去除效率低于TOC和TP。当反应器内盐浓度胁迫性增长时,混合液中SMP和EPS浓度均有增加,同时EEM荧光谱图中SMP和EPS主要响应峰均为色氨酸和色氨酸/酚物质,EPS响应峰受盐度影响明显强于SMP。 | 赵士奇 朱雷 王舒 朱先征 黄霞 | 2022 | 水处理技术2022，48，4： | 0 |

| 13 | 用EEM的特征矢量的频率分析确定芳烃混合物的组分数显示文摘混合物光谱中组分数的确定是分析化学中常要遇到的问题。因子分析方法是对一组混合物样品的数据矩阵进行特征值分析,从而确定组分数。这种方法在实际应用时有很大的局限性,例如对一个待测的多组分未知样品是无法配制一系列含有同样组分而又有不同的相对浓度,个数掇于组分数的样品。三维荧光光谱是随激发,发射波长同时变化的荧光光谱。对应于每一对激发,发射波长的各个相对荧光强度,构成了荧光的激发—发射矩阵(EEM)。它的不同行对应于不同的荧光激发波长,不同列对应不同的发射波长。一个荧光试样就可以有一个EEM。 | 何文琪 | 1992 | 计算机与应用化学1992，9，1： | 0 |
| 14 | Effects of combustion temperature on the optical properties of brown carbon from biomass burning显示文摘Biomass burning has been known as one of main sources of Brown Carbon(BrC)in atmosphere.In this study,by controlling the combustion temperature at 250℃,350℃,and 450℃,the methanol soluble organic carbon(MSOC)and methanol insoluble carbon(MISC)from pine wood burning was collected by impinger.UV–Vis,excitation emission matrix(EEM),TEM and FTIR spectra were applied to investigate the properties of BrC collected.For MSOC at 250℃ and 350℃,all the spectral profiles of UV–Vis absorption and excitation emission matrix are almost the same,while the EEM of MSOC at 450℃ are different from that of the other two.For MISC fuorescence was observed only in the case of 450℃.In the FTIR spectra,with the temperature increasing the peaks associated to the oxygen-contained functions was weakened,indicating the formation of the fuorophores with larger conjugated system,especially aromatic hydrocarbons.Our results show that biomass combustion at low temperature produces more oxygen-riched BrC,which possesses relatively lower light absorption,while at high temperature produces more aromatics hydrocarbons with relatively strong light absorption.The results of this work are helpful to trace the source of brown carbon and optimize biomass energy utilization. | Peng Gao Rule Deng Song Jia Yue Li Xuefei Wang Qian Xing | 2024 | Journal of Environmental Sciences2024，，3： | 0 |

| 17 | Evaluation of In-situ Sludge Reduction and Enhanced Nutrient Removal in an Integrated Repeatedly Coupling Aerobic and Anaerobic and Oxic-setting-anaerobic System显示文摘Aiming to achieve simultaneous good performances of in-situ sludge reduction and effluent quality,an integrated repeatedly coupling aerobic and anaerobic and oxic-setting-anaerobic system( r CAA + OSA) is developed to reduce sludge production and enhance nutrient removal. Considering the mechanism of in-situ sludge reduction in this r CAA +OSA system,the combined effect of energy uncoupling metabolism and sludge cryptic growth maybe attributed to the higher reduction of biomass. Results show that the maximal sludge reduction in this r CAA + OSA system is obtained when the hydraulic retention time( HRT) is controlled at6. 5 h,which an increase in 16. 67% reduction in excess sludge is achieved compared with OSA system( HRT of 6. 5 h). When compared the performances of effluent qualities,the enhanced nutrient removal efficiencies also can be observed in this r CAA + OSA system. Three-dimensional excitation emission matrix( 3D-EEM)fluorescence spectroscopy is applied to characterize the effluent organic matters( Ef OM) under different HRTs in the OSA and the r CAA+OSA systems. Analyses of 3D-EEM spectra show that more refractory humic-like and fulvic-like components are observed in the effluent of the OSA system. On the basis of these results,simultaneous enhanced in-situ sludge reduction and improved nutrient removal can be obtained in the r CAA +OSA systems. | Shanshan Yang Wanqian Guo Qinglian Wu Haichao Luo Simai Peng Heshan Zheng Xiaochi Feng Nanqi Ren | 2015 | Journal of Harbin Institute of Technology(New Series)2015，22，5： | 0 |
