| 1 | Humification characterization of biochar and its potential as a composting amendment显示文摘Biochar has received increasing attention due to its applications as a soil amendment. Here, the chemical properties of solid and water-extractable fractions of four biochar samples were investigated. The results showed that wood biochar and bamboo biochar samples were 60%–80% more hydrophobic than those of rice husk biochar and rice husk ash. In addition, the acidity was 3.88 mmol/g from the total functional groups and 1.03 mmol/g from the carboxyl groups/lactones/phenols found in the wood biochar sample, which were about 1.5 times greater than those of the bamboo biochar sample. These functional groups could be used to determine the sorptive capacity of biochar for ionic solutes and water content and to increase the degradation of compost organics. The wood biochar sample was found to have the most humification materials(fulvic acid-like material + humic acid-like material) in the water-extractable fraction, which was 3–10 times higher than that in the rice husk biochar and rice husk ash; humified materials were not detected in the bamboo biochar sample. Humification materials in biochar may be involved in increasing the proportion of humic acid-like materials in humic-like substances within the compost product. Wood biochar had better hydrophobic, sorptive, aromatic, and humification properties compared to other biochars, suggesting that it may be used in composting in order to exert its effect as both a bulking agent and a composting amendment during the solid waste composting process. | Jining Zhang Fan L Chenghao Luo Liming Shao Pinjing He | 2014 | Journal of Environmental Sciences2014，26，2： | 21 |
| 2 | Microstructure and properties of Al_2O_3-13%TiO_2 coatings sprayed using nanostructured powders显示文摘The microstructure and wear performance of Al2O3-13% TiO2 coatings prepared by plasma spraying of agglom- erated nanoparticle powders were investigated. SEM analysis showed that the as-sprayed Al2O3-TiO2 coatings comprise of two kinds of typical region: fully melted region and unmelted/partially melted nanostructured region, which is different than the conventional coating with lamellar structure. It is shown that the microhardness of the nanostructured coatings was about 15%-30% higher than that of the conventional coating and the wear resistance is significantly improved, especially under a high wear load. The nanostructured coating sprayed at a lower power shows a lower wear resistance than the coat- ings produced at a higher power, because of the presence of pores and microstructural defects which are detrimental to the fracture toughness of the coatings. | ZHANG Jianxin HE Jining DONG Yanchun LI Xiangzhi YAN Dianran | 2007 | Rare Metals2007，26，4： | 18 |
| 3 | Role of soil rhizobacteria in phytoremediation of heavy metal contaminated soils显示文摘Heavy metal pollution of soil is a significant environmental problem and has its negative impact on human health and agriculture. Rhizosphere, as an important interface of soil and plant, plays a significant role in phytoremediation of contaminated soil by heavy metals, in which, microbial populations are known to affect heavy metal mobility and availability to the plant through release of chelating agents, acidification, phosphate solubilization and redox changes, and therefore, have potential to enhance phytoremediation processes. Phytoremediation strategies with appropriate heavy metal-adapted rhizobacteria have re-ceived more and more attention. This article paper reviews some recent advances in effect and significance of rhizobacteria in phytoremediation of heavy metal contaminated soils. There is also a need to improve our understanding of the mechanisms in-volved in the transfer and mobilization of heavy metals by rhizobacteria and to conduct research on the selection of microbial isolates from rhizosphere of plants growing on heavy metal contaminated soils for specific restoration programmes. | JING Yan-de1,2, HE Zhen-li1,3, YANG Xiao-e1 (1Ministry of Education Key Lab of Environment, Remediation and Ecosystem Health, School of Natural Resource and Environment Science, Zhejiang University, Hangzhou 310029, China) (2Department of Resources and Planning, Qufu Normal University, Jining 273165, China) (3University of Florida Institute of Food and Agricultural Sciences, Indian River Research and Education Center, Fort Pierce, Florida 34945, USA) | 2007 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2007，8，3： | 18 |
| 4 | Water quality monitoring in a slightly-polluted inland water body through remote sensing-Case study of the Guanting Reservoir in Beijing,China显示文摘This study focused on the water quality of the Guanting Reservoir,a possible auxiliary drinking water source for Beijing.Through a remote sensing(RS)approach and using Landsat 5 Thematic Mapper(TM)data,water quality retrieval models were established and analyzed for eight common water quality variables,including algae content,turbidity,and concentrations of chemical oxygen demand,total nitrogen,ammonia nitrogen,nitrate nitrogen,total phosphorus,and dissolved phosphorus.The results show that there exists a statistically significant correlation between each water quality variable and remote sensing data in a slightly-polluted inland water body with fairly weak spectral radiation.With an appropriate method of sampling pixel digital numbers and multiple regression algorithms,retrieval of the algae content,turbidity,and nitrate nitrogen concentration was achieved within 10% mean relative error,concentrations of total nitrogen and dissolved phosphorus within 20%,and concentrations of ammonia nitrogen and total phosphorus within 30%.On the other hand,no effective retrieval method for chemical oxygen demand was found.These accuracies were acceptable for the practical application of routine monitoring and early warning on water quality safety with the support of precise traditional monitoring.The results show that performing the most traditional routine monitoring of water quality by RS in relatively clean inland water bodies is possible and effective. | Weiqi HE Shan CHEN Xuehua LIU Jining CHEN | 2008 | Frontiers of Environmental Science & Engineering2008，2，2： | 10 |
| 5 | Titanium carbonitride thick coating prepared by plasma spray synthesis and its tribological properties显示文摘TiCN coating, owing to its superior wear-resistance, has been frequently applied in many fields. TiCN thick coating was first prepared by reactive plasma spraying. The phase composition, microstructure and tribological properties of the TiCN coating were investigated in this research. Experimental results show that the microstructure of the TiCN coating was quite dense, and there was also a little amount of titanium oxides within the coating. By XPS analysis, Ti-C and Ti-N bonds were detected in the coating. The TiCN coating exhibited superior wear-resistance. The failure mechanism was attributed to the ad-hesive wear, the grinding of TiCN hard-grain, as well as the coating failure by oxidation. There were more Fe, Cr, O, etc. in the failure zone, suggesting that the corrosion propagated gradually from sur-face to interior. | ZHU Lin HE JiNing YAN DianRan XIAO LiSong DONG YanChun XUE DingChuan MENG DeLiang | 2007 | Chinese Science Bulletin2007，52，13： | 6 |
| 6 | Predicting future dynamics from short-term time series using an Anticipated Learning Machine显示文摘Predicting time series has significant practical applications over different disciplines.Here,we propose an Anticipated Learning Machine(ALM)to achieve precise future-state predictions based on short-term but high-dimensional data.From non-linear dynamical systems theory,we show that ALM can transform recent correlation/spatial information of high-dimensional variables into future dynamical/temporal information of any target variable,thereby overcoming the small-sample problem and achieving multistep-ahead predictions.Since the training samples generated from high-dimensional data also include information of the unknown future values of the target variable,it is called anticipated learning.Extensive experiments on real-world data demonstrate significantly superior performances of ALM over all of the existing 12 methods.In contrast to traditional statistics-based machine learning,ALM is based on non-linear dynamics,thus opening a new way for dynamics-based machine learning. | Chuan Chen Rui Li Lin Shu Zhiyu He Jining Wang Chengming Zhang Huanfei Ma Kazuyuki Aihara Luonan Chen | 2020 | National Science Review2020，7，6： | 3 |

| 20 | Mechanism and control of ground residual deformation over longwall goaf显示文摘The deformation of rupture rock mass in goaf is the main reason for ground terrene residual deformation. Based on field measurement and similar material simulation, the rupture strata structure and its residual deformation characteristics in the longwall goaf and its overburden are pointed out. On the basis of these achievements, the authors propose the mechanism of strengthening rupture rock mass ground and the control measures of deformation resistant structure. Using the case of main coal building in Xinzhuangzi Coal Processing Plant, this paper introduces the influence of strengthening rupture rock mass and deformation resistant structure. | GUO Guang-li~1, WEI Kuang-ling~2, MU Bin-shan~3, Gao Jing-xiang~1, HE Guo-qing~1 (1.
