| 1 | Adsorption–desorption behavior of atrazine on agricultural soils in China显示文摘Adsorption and desorption are important processes that affect atrazine transport,transformation,and bioavailability in soils.In this study,the adsorption–desorption characteristics of atrazine in three soils(laterite,paddy soil and alluvial soil) were evaluated using the batch equilibrium method.The results showed that the kinetics of atrazine in soils was completed in two steps:a'fast' adsorption and a 'slow' adsorption and could be well described by pseudo-second-order model.In addition,the adsorption equilibrium isotherms were nonlinear and were well fitted by Freundlich and Langmuir models.It was found that the adsorption data on laterite,and paddy soil were better fitted by the Freundlich model;as for alluvial soil,the Langmuir model described it better.The maximum atrazine sorption capacities ranked as follows:paddy soil > alluvial soil > laterite.Results of thermodynamic calculations indicated that atrazine adsorption on three tested soils was spontaneous and endothermic.The desorption data showed that negative hysteresis occurred.Furthermore,lower solution pH value was conducive to the adsorption of atrazine in soils.The atrazine adsorption in these three tested soils was controlled by physical adsorption,including partition and surface adsorption.At lower equilibrium concentration,the atrazine adsorption process in soils was dominated by surface adsorption;while with the increase of equilibrium concentration,partition was predominant. | Lin Yue ChengJun Ge Dan Feng Huamei Yu Hui Deng Bomin Fu | 2017 | Journal of Environmental Sciences2017，29，7： | 16 |
| 2 | Hydration Mechanism of Sulphoaluminate Cement显示文摘The feasibility of sulphoaluminate cement (SAC) utilization in support mortar was studied. Setting time and strength of as-received sulphoaluminate cement (SAC) paste were examined, hydration kinetics behavior was determined through Isothermal Calorimeter, and hydration mechanism was investigated by X-Ray diffraction analysis (XRD) and field emission scanning electron microscopy analysis(FSEM). Results showed that as-received SAC contained 61% of anhydrous calcium sulfate (3CA·CaSO4) and dicalcium silicate (C2S). The strength after 1 day or 3 days grew to 68.6% or 85.7% of that after 28 days respectively, while most of hydration heat was released within 1 day. The emergency of three exothermic peaks at acceleration stage was found and hydration kinetics model was established choosing the terminal time of the first exothermic peak at accelerating stage as the beginning of accelerating stage. XRD analysis suggested that large amount of ettringite (AFt) was produced at early age and FSEM observation revealed that ettringite (AFt) formed in sulphoaluminate cement (SAC) paste was characterized of different morphology which was proved to be caused by different ion concentrations. | 何真 YANG Huamei LIU Meiyan | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，1： | 13 |
| 3 | Enhanced pyrocatalysis of the pyroelectric BiFeO_(3)/g-C_(3)N_(4) heterostructure for dye decomposition driven by cold–hot temperature alternation显示文摘The BiFeO_(3)/g-C_(3)N_(4) heterostructure,which is fabricated via a simple mixing–calcining method,benefits the significant enhancement of the pyrocatalytic performance.With the growth of g-C_(3)N_(4) content in the heterostructure pyrocatalysts from 0 to 25%,the decomposition ratio of Rhodamine B(RhB)dye after 18 cold-hot temperature fluctuation(25-65℃)cycles increases at first and then decreases,reaching a maximum value of~94.2%at 10%while that of the pure BiFeO_(3) is~67.7%.The enhanced dye decomposition may be due to the generation of the internal electric field which strengthens the separation of the positive and negative carriers and further accelerates their migrations.The intermediate products in the pyrocatalytic reaction also have been detected and confirmed,which proves the key role of the pyroelectric effect in realizing the dye decomposition using BiFeO_(3)/g-C_(3)N_(4) heterostructure catalyst.The pyroelectric BiFeO_(3)/g-C_(3)N_(4) heterostructure shows the potential application in pyrocatalytically degrading dye wastewater. | Mingzi Chen Yanmin Jia Huamei Li Zheng Wu Tianyin Huang Hongfang Zhang | 2021 | Journal of Advanced Ceramics2021，10，2： | 6 |
| 4 | KAI1/CD82 gene expression in benign prostatic hyperplasia and late-stage prostate cancer in Chinese显示文摘Aim: To evaluate KAI1/CD82 expression in Chinese patients with benign prostatic hyperplasia (BPH) and latestage carcinoma of prostate (CAP). Methods: Thirty Chinese patients with benign prostatic hyperplasia and 34 with CaP (adenocarcinoma clinical stage C and D) were analyzed by means of immunohistochemical methods. Results: The KAI1/CD82 expression in BPH tissue was all positive, which was uniformly located on the glandular cell membrane at the cell-to-cell borders, but KAI1/CD82 expression in metastasis CaP tissues was either significantly lower than that of BPH or negative, and the immunostaining pattern was not continuous. In late-stage CaP KAI1/CD82 expression was correlated inversely to the pathological grade ( P < 0.05), but not to clinical stage ( P > 0.05). Conclusion: The authors believe that decreased and negative KAI1/CD82 expression in late-stage CAP may be related to tumor pro-gression and metastasis, and appears to be a prognostic marker. | Wei-LieHU Ying-QiuLI Hui-XuHE Qing-RongLI YeTIAN Ri-QuanLAI HuaMEI | 2000 | Asian Journal of Andrology2000，2，3： | 6 |
| 5 | Genome-wide detection of additional fetal chromosomal abnormalities by cell-free DNA testing of 15,626 consecutive pregnant women显示文摘Cell-free DNA(cfDNA) testing for common fetal trisomies(T21, T18, T13) is highly effective. However, the usefulness of cfDNA testing in detecting other chromosomal abnormalities is unclear. We evaluated the performance of cfDNA testing for genome-wide abnormalities, and analyzed the incremental yield by reporting extra abnormalities. We performed genome-wide cfDNA testing in 15,626 consecutive pregnancies prospectively enrolled in this study. cfDNA testing results were reported and counseling was given depending on the presence of extra chromosomal abnormalities. cfDNA testing identified 190 cases(1.2%)of chromosomal abnormalities including 100 common trisomies and 90 additional abnormalities. By expanding the cfDNA reporting range to genome-wide abnormalities, the false positive rate increased to 0.39%(P<0.001) and positive predictive value(PPV) was reduced to 65.58%(P=0.42). However, the detection yield increased from 0.44% to 0.65%(P=0.014), and cfDNA testing detected 38.61%(39/101) additional abnormalities with no ultrasound and biochemical screening findings. cfDNA testing outperformed biochemical screening by showing 60 times higher true positive rate and fewer false negative results.Genome-wide cfDNA testing significantly increased the diagnostic yield by detecting extra abnormalities, especially those without diagnostic indications. Genome-wide cfDNA testing has fewer false positive and false negative results compared with biochemical screening. | Hong Yao Ya Gao Jia Zhao Rong Zhang Huixin Xu Huamei Hu Yanmei Luo Yuying Yuan Meili Fu Hongyun Zhang Hui Jiang Wei Wang Huanming Yang Jian Wang Zhiqing Liang Fang Chen | 2019 | Science China(Life Sciences)2019，62，2： | 4 |
| 6 | Magnetic properties of Jiaxian red clay sequences from northern Chinese Loess Plateau and its paleoclimatic significance显示文摘Detailed rock magnetism investigation of the Jiaxian red clay sequences indicated that there are common magnetic mineralogy properties in red clay and loess-paleosol sequences from the Chinese Loess Plateau as well as the marked properties of themselves, magnetic min-erals mainly with magnetite, maghemite, hematite, and possibly limonite/goethite contributing to the magnetic behavior. Meanwhile, it is found that the strong paleosol in red clay sequences has a lower coercivity and higher content of ultra-fine ferrimagnetic grains than that of the weak pa-leosol, which is similar to loess and paleosol in upper Wucheng Loess sequences, and indicates that humid conditions and relatively strong pedogenesis play a significant role in the increase of ultra-fine magnetic minerals and transformation of the magnetic minerals. This suggests that, like Quaternary loess-paleosols, the change of characteristics of paleoclimatic conditions of the late Tertiary red clay deposits is fluctuant. In addition, the results of magnetic hysteresis properties show that the applied saturated field for samples from the Jiaxian red clay sequences is higher than that of the samples from eastern and southern Chinese Loess Plateau. It is obviously shown that there exist more hard magnetic minerals and relatively weak biochemical processes in the Jiaxian red clay sequences on northern Chinese Loess Plateau. We conclude that the paleocli-matic environment is different between northern and eastern/southern Chinese Loess Plateau, and it should be more arid in northern Chinese Loess Plateau. | QIANG Xiaoke, AN Zhisheng, LI Huamei, CHANG Hong & SONG Yougui 1.

| 7 | Quantitative effects of phase transition on solute partition coefficient,inclusion precipitation, and microsegregation for high-sulfur steel solidification显示文摘Segregation and inclusion precipitation are the common behaviours of steel solidification, which are resulted from the redistribution and diffusion of the solute elements at the solid-liquid interface. The effect of the phase transition of high-sulfur free-cutting steel is quantified in the present work for the solute partition coefficient(ki), inclusion precipitation, and microsegregation by establishing a coupling model of microsegregation and inclusion precipitation, wherein the quantified dependencies of ki in terms of temperature, phase and carbon(C) content were applied. Results showed that the solidification temperature range and phase transition of high-sulfur steel that under different solidification paths and C contents were quite different, leading to differences in ki and eventually in microsegregation. kC,kP, and kS were mainly affected by phase composition and kSi was primarily by temperature, while kMn depended on both phase composition and temperature during solidification. Increasing the C content within the interval 0.07-0.48 wt%, the ‘proportion of the δ phase maintained temperature region during solidification’(Pδ), kave Pand kave S(kiave, the average value of the ki across the whole stages of solidification)decreased monotonically, whereas kave Cincreased linearly. The peritectic reaction impacted on the phase composition and ki, leading to the change in microsegregation. Such effect of the peritectic reaction was more significant at the last stage of solidification. When the Pδ was between 75% and 100%(corresponding to 0.07-0.16 wt% C), the solidification path resulted in a greater effect on the microsegregation of solutes C, P, and S because of the peritectic reaction. The microsegregation of solutes Mn and S were comprehensively influenced by kMn, kS and Mn S precipitation as well. The studies would help reveal the solute redistribution at the solid-liquid interface, and improve the segregation of high-sulfur steel by controlling the solidification and precipitation in practice. | Lintao Gui Mujun Long Shixin Wu Zhihua Dong Dengfu Chen Yunwei Huang Huamei Duan Levente Vitos | 2019 | Journal of Materials Science & Technology2019，35，10： | 3 |
| 8 | Phylogeography and Cryptic Species Diversity of Paramesotriton caudopunctatus Species Group(Salamandridae: Paramesotriton) in Guizhou, China显示文摘The Paramesotriton caudopunctatus species group is mainly distributed in the karst mountain ecosystems of Guizhou, China. Although some species have been included in previous phylogenetic studies, the evolutionary relationships and divergence-time of members of this species group as a whole remain unexplored. In this study, we report the sequencing of one protein coding mitochondrial gene fragment(ND2) and one nuclear gene(POMC), and use a combination of phylogenetic analyses and coalescent simulations to explore the cryptic diversity and evolutionary history of the P. caudopunctatus species group. Phylogenetic relationships revealed that the P. caudopunctatus species group is composed of two major groups, i. e., East Clade and Western-South Clade. The divergence-time and ancestral area estimation suggested that the P. caudopunctatus species group likely originated in the Doupeng Mountains in Guizhou, China at 12.34 Ma(95% HPD: 8.30–14.73), and intraspecific divergence began at about 2.17 Ma(95% HPD: 1.39–2.97). This timing coincides with the orogenesis of the Miaoling Mountains during the Late Miocene to early Pleistocene. The delimitation of species in the P. caudopunctatus species group supports the existence of the currently identified species, and consensus was confirmed across methods for the existence of least to two cryptic species within what has been traditionally considered to be P. caudopunctatus species group. This study is of significance for understanding the species formation, dispersal, and diversity of the tailed amphibians in the karst mountains ecosystem of Guizhou and the role of the Miaoling Mountains as a geographical barrier to species dispersal. | Tao LUO Huamei WEN Kai GAO Jun ZHOU Jiang ZHOU | 2021 | Asian Herpetological Research2021，12，2： | 2 |
| 9 | Rock magnetic properties and palaeomagnetic results of sediments from a stone implement layer in the Bose Basin, Guangxi显示文摘Directional samples were taken to study rock magnetism and palaeomagnetic records from the Dong- sheng profile, which is 5 m thick and on the northwest edge of the Bose Basin. Mineralogy and rock magnetism of typical samples indicate that coarse granular titanomagnetite, and fine-grained hematite, superparamagnetic maghemite formed by pedogenesis are in the sediment, which has undergone many transformative processes during different stages of pedogenesis. Parallel samples were taken for thermal demagnetization (TH) (0 to 680℃) and alternating field (AF) demagnetization (0 to 80 mT) respectively. Experimental results of these two kinds of demagnetization illustrate that there are two or more magnetic components in the samples. Intensity of NRM decreases by almost 60% to 90% rapidly when the temperature ranges from 100℃ to 350℃, with a steady magnetic component. It is impossible to analyze the magnetic components at high temperature because those fluctuate widely when the temperature is higher than 400℃. Steady magnetic components from 100℃ to 350℃ indicate that the remanence was mainly carried by fine-grained hematite formed by pedogenesis, reflecting a change in the geomagnetic field while the magnetite was being oxidized into hematite by chemical weathering after deposition. The formative age of the sediments cannot be obtained by magnetic methods in this profile. | YANG XiaoQiang ZHU ZhaoYu ZHANG YiNan LI HuaMei ZHOU WenJuan YANG Jie | 2008 | Science China Earth Sciences2008，51，3： | 2 |
| 10 | Hydro-Abrasive Erosion of Concrete Incorporated with Nano-SiO_2, Super-Fine Slag or Rubber Powder显示文摘In this paper, we investigates the concretes respectively incorporated with 5%(m︰m) nano-SiO2(NS), 40%(m︰m) super- fine slag(SS), as well as 40%(m︰m) SS combining 20% replacement of sand volume with RP. The tested mechanical properties include compressive strength, abrasion resistant strength, and elastic modulus. The results indicate that among these concretes, the SS-RP concrete has the highest abrasion resistant strength with increment ratios of 1.71 and 1.35 at 28 days and 90 days, respectively; the SS concrete has the highest compressive strength with increment ratios of 2.03 and 1.95 at 28 days and 90 days, respectively; the elastic modulus of SS-RP concrete significantly decrease compared with the SS concrete and is slightly higher than that of the reference concrete. It is concluded that NS, SS, and RP all can improve the abrasion resistance of concrete, and it will be significantly improved when SS combining RP is incorporated. | HE Zhen CHEN Xiaorun YANG Huamei CAI Xinhua | 2013 | Wuhan University Journal of Natural Sciences2013，18，6： | 2 |
| 11 | Automatic Placement of GIS Vector Map Annotation in Area Feature by Long Diagonal显示文摘This paper discusses the placement of Chinese annotation from point of view of graphics. Area Feature is classified as simple polygon, complex polygon and special polygon. For simple ones, annotations are placed along the longest edge. For complex ones, firstly the polygon are simplified according to close points, then the longest diagonal is gotten by comparing length, lastly, annotations are placed along long diagonal. For special ones, the polygon are partitioned into several parts by a certain rule for getting their sub\|diagonals, then their annotation are placed by means of the second. | LAN Xiaoji JIANG Yongfa Lü Guonian DENG Huamei | 2005 | Geo-Spatial Information Science2005，8，4： | 2 |
| 12 | Research on the Angular Glint of Targets in the Near-Zone显示文摘This paper presents a method to analyze and calculate the angular glint of targets. By parting the target to very small size cells,using high-frequency approximation,the near-field radar cross section (RCS) is calculated based on the scattering from complex targets and environments (SCTE) system,and the angular glint is calculated by the phase grads. The results show that the angular glint can be calculated exactly in the SCTE system,and this method is correct and efficient. In the near-zone,the far-field theory is not applicable and the angular glint should be calculated by the near-field theory. | XIA Yingqing TIAN Huamei DUAN Zhiguo WU Ling XU Penggen | 2007 | Wuhan University Journal of Natural Sciences2007，12，3： | 2 |
| 13 | Molecular phylogeny and historical biogeography of the cave fish genus Sinocyclocheilus(Cypriniformes:Cyprinidae)in southwest China显示文摘Modern accumulations of genetic data offer unprecedented opportunities for understanding the systematic classification and origins of specific groups of organisms.The genus Sinocyclocheilus is among the most cave abundant genera in Cyprinidae,with 76 recognized species,belonging to 4 species groups.Recent phylogenetic studies have shown that the classification of species groups within the genus Sinocyclocheilus remains controversial.In this study,we constructed a sequence supermatrix of 26 species from 4 species groups of the genus Sinocyclocheilus using the mitochondrial genome to reveal phylogenetic relationships,historical biogeography and patterns of species diversification in the genus Sinocyclocheilus.Phylogenetic analysis strongly supports the monophyletic groups of the 3 species groups(S.jii,S.cyphotergous,and S.tingi groups)except the S.angularis group.Phylogenetic analysis showed that S.anshuiensis and S.microphthalmus,which were recognized as numbers of S.angularis group,formed a strongly supported independent clade.Therefore,we propose a new species group,the S.microphthalmus group,which contains S.anshuiensis and S.microphthalmus.Biogeographic reconstruction suggests that the living Sinocyclocheilus may have originated in north-central Guangxi at the late Eocene and dispersed outward after a vicariance at 32.31 Million years ago(Ma).Early diversification is focused on the late Oligocene(ca.25 Ma),which is related to the second uplift of the Qinghai−Tibetan Plateau and the lateral extrusion of the Indochina at the Oligocene/Miocene boundary.Our results suggest that 2 uplifts of the Qinghai−Tibetan Plateau and climate change in the Miocene may have influenced the diversification of the Sinocyclocheilus lineage. | Huamei WEN Tao LUO Yali WANG Siwei WANG Tao LIU Ning XIAO Jiang ZHOU | 2022 | Integrative Zoology2022，17，2： | 2 |
