| 1 | Complexity of software trustworthiness and its dynamical statistical analysis methods显示文摘Developing trusted softwares has become an important trend and a natural choice in the development of software technology and applications. At present,the method of measurement and assessment of software trustworthiness cannot guarantee safe and reliable operations of software systems completely and effectively. Based on the dynamical system study,this paper interprets the characteristics of behaviors of software systems and the basic scientific problems of software trustworthiness complexity,analyzes the characteristics of complexity of software trustworthiness,and proposes to study the software trustworthiness measurement in terms of the complexity of software trustworthiness. Using the dynamical statistical analysis methods,the paper advances an invariant-measure based assessment method of software trustworthiness by statistical indices,and hereby provides a dynamical criterion for the untrustworthiness of software systems. By an example,the feasibility of the proposed dynamical statistical analysis method in software trustworthiness measurement is demonstrated using numerical simulations and theoretical analysis. | ZHENG ZhiMing MA ShiLong LI Wei JIANG Xin WEI Wei MA LiLi TANG ShaoTing | 2009 | Science in China(Series F)2009，52，9： | 11 |
| 2 | A review of the synthesis and application of zeolites from coal-based solid wastes显示文摘Zeolite derived from coal-based solid wastes(coal gangue and coal fly ash)can overcome the environmental problems caused by coal-based solid wastes and achieve valuable utilization.In this paper,the physicochemical properties of coal gangue and coal fly ash are introduced.The mechanism and application characteristics of the pretreatment processes for zeolite synthesis from coal-based solid wastes are also introduced.The synthesis processes of coal-based solid waste zeolite and their advantages and disadvantages are summarized.Furthermore,the application characteristics of various coal-based solid waste zeolites and their common application fields are illustrated.Finally,we propose an alkaline fusion-assisted supercritical hydrothermal crystallization as an efficient method for synthesizing coal-based solid waste zeolites.In addition,more attention should be given to the recycling of alkaline waste liquid and the application of coal-based solid waste zeolites in the field of volatile organic compound adsorption removal. | Xiaoyu Zhang Chunquan Li Shuilin Zheng Yonghao Di Zhiming Sun | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 10 |
| 3 | Hierarchical assembly of highly efficient visible-light-driven Ag/g-C_(3)N_(4)/kaolinite composite photocatalyst for the degradation of ibuprofen显示文摘A novel Ag/g-C_(3)N_(4)/kaolinite composite photocatalyst was fabricated for the first time through a two-step assembly strategy by employing in situ calcination and a photodeposition process.The synthesized Ag/g-C_(3)N_(4)/kaolinite composite reached a higher degradation rate of ibuprofen(IBP)with a reaction rate constant of 0.0113 min^(-1) at an Ag content of 7% under visible-light irradiation,which was approximately 1.87 times that of the Ag/g-C_(3)N_(4) composite.Based on the physicochemical properties,the enhanced photocatalytic activity was attributed to the stronger adsorption property,wider photoresponse range and more efficient separation and transfer of electron-hole pairs.Furthermore,the incorporation of monodispersed Ag nanoparticles onto the g-C_(3)N_(4)/kaolinite sheets provided more reactive sites for the IBP degradation.In addition,according to the EPR study and trapping experiments,it was demonstrated that holes(h^(+))should be the key reactive species.A possible pathway of IBP degradation was also proposed based on the detected intermediates.Overall,the results of this work may facilitate the design of a novel visible-light-driven photocatalyst with a high efficiency that is derived from a natural mineral for environmental remediation. | Zhiming Sun Xiangwei Zhang Xiongbo Dong Xiaorui Liu Ye Tan Fang Yuan Shuilin Zheng Chunquan Li | 2020 | Journal of Materiomics2020，6，3： | 8 |
| 4 | Dynamical characteristics of software trustworthiness and their evolutionary complexity显示文摘Developing trusted softwares has become an important trend and a natural choice in the development of software technology and applications, and software trustworthiness modeling has become a prerequisite and necessary means. To discuss and explain the basic scientific problems in software trustworthiness and to establish theoretical foundations for software trustworthiness measurement, combining the ideas of dynamical system study, this paper studies evolutionary laws of software trustworthiness and the dynamical mechanism under the effect of various internal and external factors, and proposes dynamical models for software trustworthiness, thus, software trustworthiness can be considered as the statistical characteristics of behaviors of software systems in the dynamical and open environment. By analyzing two simple examples, the paper explains the relationship between the limit evolutionary behaviors of software trustworthiness attributes and dynamical system characteristics, and interprets the dynamical characteristics of software trustworthiness and their evolutionary complexity. | ZHENG ZhiMing MA ShiLong LI Wei WEI Wei JIANG Xin ZHANG ZhanLi GUO BingHui | 2009 | Science in China(Series F)2009，52，8： | 8 |
| 5 | Finite-time disturbance attenuation of nonlinear systems显示文摘This paper is devoted to the finite-time disturbance attenuation problem of affine nonlinear systems. Based on the finite time Lyapunov stability theory, some finite-time H∞ performance criterions are derived. Then the state-feedback control law is designed and the structure of such a controller is investigated. Furthermore, it is shown that the H∞ controller can also make the closed-loop system satisfy finite-time H∞ performance for nonlinear homogeneous systems. An example is provided to demonstrate the effectiveness of the presented results. | MO LiPo JIA YingMin ZHENG ZhiMing | 2009 | Science in China(Series F)2009，52，11： | 8 |
| 6 | Review of the atmospheric corrosion of magnesium alloys显示文摘Mg atmospheric corrosion is induced by a thin surface aqueous layer. Controlling factors are microgalvanic acceleration between different phases, protection by a continuous second phase distribution, protection by corrosion products, and degradation of protective layers by aggressive species such as chloride ions. The Mg atmospheric corrosion rate increases with relative humidity (RH) and concentrations of aggressive species. Temperature increases the corrosion rate unless a protective film causes a decrease.O2, SO2 and NO2 accelerate the atmospheric corrosion rate, whereas the corrosion rate is decreased by CO2. The traditional gravimetric method can evaluate effectively the corrosion behavior of Mg alloys. | Hongguang Liu Fuyong Cao Guang-Ling Song Dajiang Zheng Zhiming Shi Mathew S.Dargusch Andrej Atrens | 2019 | Journal of Materials Science & Technology2019，35，9： | 7 |
| 7 | High performance columnar-like Fe2O3@carbon composite anode via yolk@shell structural design显示文摘Conversion-type reaction anode materials with high specific capacity are attractive candidates to improve lithium ion batteries(LIBs), yet the rapid capacity fading and poor rate capability caused by drastic volume change and low electronic conductivity greatly hinder their practical applications. To circumvent these issues, the successful design of yolk@shell Fe2 O3@C hybrid composed of a columnar-like Fe2O3 core within a hollow cavity completely surrounded by a thin, self-supported carbon(C) shell is presented as an anode for high-performance LIBs. This yolk@shell structure allows each Fe2O3 core to swell upon lithiation without deforming the carbon shell. This preserves the structural and electrical integrity against pulverization, as revealed by in situ transmission electron microscopy(TEM) measurement. Benefiting from these structural advantages, the resulting electrode exhibits a high reversible capacity(1013 m Ah g-1 after80 cycles at 0.2 A g-1), outstanding rate capability(710 m Ah g-1 at 8 A g-1) and superior cycling stability(800 m Ah g-1 after 300 cycles at 4 A g-1). A Li-ion full cell using prelithiated yolk@shell Fe2 O3@C hybrid as the anode and commercial Li CoO2(LCO) as the cathode demonstrates impressive cycling stability with a capacity retention of 84.5% after 100 cycles at 1 C rate, holding great promise for future practical applications. | Zhiming Zheng Pei Li Jason Huang Haodong Liu Yi Zao Zhongli Hu Li Zhang Huixin Chen Ming-Sheng Wang Dong-Liang Peng Qiaobao Zhang | 2020 | Journal of Energy Chemistry2020，29，2： | 7 |

| 9 | Synthesis of a novel illite@carbon nanocomposite adsorbent for removal of Cr(Ⅵ)from wastewater显示文摘A novel illite@carbon(I@C) nanocomposite adsorbent has been synthesized via a facile hydrothermal carbonization process(HTC) using glucose as carbonaceous source and illite as the carrier.The morphology,microstructure and surface properties of the prepared nanocomposite adsorbent were analyzed by FESEM,TGA,XRD,FT-IR and Zeta potential measurements.Batch experiments were carried out on the adsorption of Cr(Ⅵ) to determine the adsorption properties of the composite.The adsorption of Cr(Ⅵ) onto the I@C nanocomposite was well described by the pseudo-second-order kinetic model and Langmuir isotherm.Compared with the illite and carbon material(SC) separately,the prepared I@C nanocomposite adsorbent exhibited enhanced adsorption performance for Cr(Ⅵ) with a maximum adsorption capacity of 149.25 mg/g,which was higher than that of most reported adsorbents.In addition,the adsorption process was spontaneous and endothermic based on the adsorption thermodynamics study.The adsorption of Cr(Ⅵ) by I@C was highly p H-dependent and the optimum adsorption occurred at p H 2.0.The Zeta potential analysis results indicated that the electrostatic interactions between anionic Cr(Ⅵ) and the positively charged surface of the adsorbent might be critical to the adsorption mechanism.This study demonstrated that the I@C nanocomposite should be a promising candidate for a low-cost,environmental friendly and highly efficient adsorbent for the removal of toxic Cr(Ⅵ) from wastewater. | Gaofeng Wang Shan Wang Wen Sun Zhiming Sun Shuilin Zheng | 2017 | Journal of Environmental Sciences2017，29，7： | 7 |
| 10 | High precision attitude dynamic tracking control of a moving space target显示文摘On-orbit spacecraft face many threats,such as collisions with debris or other spacecraft.Therefore,perception of the surrounding space environment is vitally important for on-orbit spacecraft.Spacecraft require a dynamic attitude tracking ability with high precision for such missions.This paper aims to address the above problem using an improved backstepping controller.The tracking mission is divided into two phases:coarse alignment and fine alignment.In the first phase,a traditional saturation controller is utilized to limit the maximum attitude angular velocity according to the actuator’s ability.For the second phase,the proposed backstepping controller with different virtual control inputs is applied to track the moving target.To fulfill the high precision attitude tracking requirements,a hybrid attitude control actuator consisting of a Control Moment Gyro(CMG)and Reaction Wheel(RW)is constructed,which can simultaneously avoid the CMG singularity and RW saturation through the use of an angular momentum optimal management strategy,such as null motion.Finally,five simulation scenarios were carried out to demonstrate the effectiveness of the proposed control strategy and hybrid actuator. | Yunhua WU Mohong ZHENG Wei HE Feng WANG Zhiming CHEN Bing HUA | 2019 | Chinese Journal of Aeronautics2019，32，10： | 6 |
| 11 | Primary Study on Quantitative Reconstruction of Middle-Late Eocene Climate in Jianghan Basin显示文摘This paper reports our primary effort in the quantitative reconstruction of paleoclimate based on the thrine in phytoecology of the affinity parent plants in the stratigraphic pollen records. The Eocene pollen data come from our former study on the Mingjia borehole 1 in the Jianghan basin. The fluctuating trend in the parameter curve of climate shows that the climate in the Middle Eocene in the Jianghan basin was more or less comparable with that of the present 22°-26°N, characteristic of a humid, semi humid central southern subtropical climate. The annual temperature at that time dropped by 1 ℃-4 ℃ in the Late Eocene, approximately equal to that of the present 23°-28°N of northern central subtropical climate. However, the climate composite at that time, characterized by higher temperature, small annual range and big fluctuation in precipitation, was quite different from the present one. The average temperature in January in the Middle Eocene, higher than that of today, ranged between 5 ℃ and 9 ℃, indicating that no effect of winter monsoon occurred in the Middle Eocene, though such an effect may have occurred occasionally in the Late Eocene. Major temperature decline is recognized at the depth of 2 100 m in the borehole, as was indicated by the decline in average January temperature, the increase in annual range, and the increase in the deciduous broad leaved types of trees in the spore pollen assemblage. The sharp fluctuation in the annual precipitation, usually raging from 300 to 1 700 mm, was favorable for the migration and accumulation of salty deposit. When the precipitation was lower than 1 000 mm, ephemera shrub increased at the same depth as that of the salty deposit. It is, therefore, deduced that the formation of the salty deposit was attributed mainly to the dry and hot environment in the high mountains and deep basins. The small annual precipitation and the intense fluctuation are favorable for the sustainable accumulation of the salts, which is different from the present salty accumulation in the Northwest China. | Tong Guobang Liu Zhiming Institute of Hydrogeology and Environmental Geology, Chinese Academy of Geological Sciences, Zhengding 050803 Open Laboratory of Saline Lake Resources and Environment, Chinese Academy of Geological Sciences, Beijing 100037 Zheng Mianping Institute of Mineral Resources, Chinese Academy of Geological Sciences, Beijing 100037 Research & Development Center of Saline Lake and Epithermal Deposit, Chinese Academy of Geological Sciences, Beijing 100037 Wang Weiming Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, Nanjing 210008 | 2002 | Journal of China University of Geosciences2002，13，3： | 5 |
| 12 | Diatomite supported nano zero valent iron with 3D network for peroxymonosulfate activation in efficient degradation of bisphenol A显示文摘Diatomite supported nano zero valent iron(n ZVI)catalyst(NDA)with complex network structure was prepared via a mild reduction precipitation method in this work.The pore structure and pore distribution of NDA can be regulated and controlled through adjusting the loading amount of n ZVI.In general,the nano three-dimensional network formed by n ZVI and diatomite channels greatly increase the specific surface area and pore volume of NDA,and further formed more active sites,which made NDA have better performance in activating PMS to degrade BPA than pure n ZVI.The pseudo-first-order reaction rate constant of 50-NDA(50%-n ZVI/diatomite)is almost 3 times higher than that of pure n ZVI.Besides,the electron paramagnetic resonance(EPR)and radical quenching experiments showed that the activation process was dominated by the sulfate radical(SO_(4)^(-))and hydroxyl radical(·OH)produced by Fe;oxidation.The generated electrons promote the self-decomposition of PMS to produce singlet oxygen(^(1)O_(2)),and then the valence state of iron changes to produce free radicals.In addition,the possible degradation pathway of BPA was inferred from the intermediate products identified by liquid chromatograph-mass spectrometer(LC-MS).This study provides a novel strategy for the design and preparation of three-dimensional composite catalysts derived from natural mineral. | Ye Tan Shuilin Zheng Yonghao Di Chunquan Li Runze Bian Zhiming Sun | 2021 | Journal of Materials Science & Technology2021，，36： | 4 |

| 14 | Correlation Between Microstructure and Corrosion Behavior of Two 90Cu10Ni Alloy Tubes显示文摘Two kinds of 90Cu10 Ni tubes with different service lives(more than 3 years and only 1 year,respectively)under identical working conditions were studied by an immersion test in a 3.5 wt% NaCl solution and the electron backscattered diffraction(EBSD) technique.The morphology after immersion showed severer corrosion attack at the grain boundaries of the tube with shorter service life compared with the tube with longer service life.The grain boundary characterization distributions(GBCDs) of the two tubes obtained by EBSD revealed more Σ3 boundaries and twins,and larger random boundary meshes in the tube with longer service life.A short immersion test in a modified Livingston's solution was conducted to evaluate the tendency to corrosion attack of different types of the grain boundaries.SEM and AFM were used to characterize the corrosion morphologies of the boundaries.A strong correlation between varying depths of corrosion grooves and types of the grain boundaries was obtained.The influence of deviation angle of low Σ boundaries on corrosion resistance of the grain boundaries was also discussed.It is concluded that a special ‘‘grain boundary engineering''(GBE) treatment has been performed on the tube with longer service life.It is proposed that the optimized GBCD is responsible for the better service performance of the tube. | Aili Ma Shengli Jiang Yugui Zheng Zhiming Yao Wei Ke Shuang Xia | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，4： | 4 |
| 15 | Geoscience knowledge graph in the big data era显示文摘Since the beginning of the 21 st century,the geoscience research has been entering a significant transitional period with the establishment of a new knowledge system as the core and with the drive of big data as the means.It is a revolutionary leap in the research of geoscience knowledge discovery from the traditional encyclopedic discipline knowledge system to the computer-understandable and operable knowledge graph.Based on adopting the graph pattern of general knowledge representation,the geoscience knowledge graph expands the unique spatiotemporal features to the Geoscience knowledge,and integrates geoscience knowledge elements,such as map,text,and number,to establish an all-domain geoscience knowledge representation model.A federated,crowd intelligence-based collaborative method of constructing the geoscience knowledge graph is developed here,which realizes the construction of high-quality professional knowledge graph in collaboration with global geo-scientists.We also develop a method for constructing a dynamic knowledge graph of multi-modal geoscience data based on in-depth text analysis,which extracts geoscience knowledge from massive geoscience literature to construct the latest and most complete dynamic geoscience knowledge graph.A comprehensive and systematic geoscience knowledge graph can not only deepen the existing geoscience big data analysis,but also advance the construction of the high-precision geological time scale driven by big data,the compilation of intelligent maps driven by rules and data,and the geoscience knowledge evolution and reasoning analysis,among others.It will further expand the new directions of geoscience research driven by both data and knowledge,break new ground where geoscience,information science,and data science converge,realize the original innovation of the geoscience research and achieve major theoretical breakthroughs in the spatiotemporal big data research. | Chenghu ZHOU Hua WANG Chengshan WANG Zengqian HOU Zhiming ZHENG Shuzhong SHEN Qiuming CHENG Zhiqiang FENG Xinbing WANG Hairong LV Junxuan FAN Xiumian HU Mingcai HOU Yunqiang ZHU | 2021 | Science China Earth Sciences2021，64，7： | 4 |

| 17 | Digital signature systems based on smart card and fingerprint feature显示文摘Two signature systems based on smart cards and fingerprint features are proposed. In one signature system, the cryptographic key is stored in the smart card and is only accessible when the signer's extracted fingerprint features match his stored template. To resist being tampered on public channel, the user's message and the signed message are encrypted by the signer's public key and the user's public key, respectively. In the other signature system, the keys are generated by combining the signer's fingerprint features, check bits, and a rememberable key, and there are no matching process and keys stored on the smart card. Additionally, there is generally more than one public key in this system, that is, there exist some pseudo public keys except a real one. | You Lin Xu Maozhi Zheng Zhiming | 2007 | Journal of Systems Engineering and Electronics2007，18，4： | 3 |
| 18 | Comparative WGBS identifies genes that influence non-ripe phenotype in tomato epimutant Colourless non-ripening显示文摘Whole-genome bisulfite sequencing(WGBS)allows single-base resolution and genome-wide profiling of DNA methylation in plants and animals.This technology provides a powerful tool to identify genes that are potentially controlled by dynamic changes of DNA methylation and demethylation.However,naturally occurring epimutants are rare and genes under epigenetic regulation as well as their biological relevances are often difficult to define.In tomato,fruit development and ripening are a complex process that involves epigenetic control.We have taken the advantage of the tomato epimutant Colourless non-ripening(Cnr)and performed comparative mining of the WGBS datasets for the Cnr and Sl CMT3-silenced Cnr fruits.We compared DNA methylation profiles for the promoter sequences of approximately 5,000 bp immediately upstream of the coding region of a list of20 genes.Differentially methylated regions were found for some of these genes.Virus-induced gene silencing(VIGS)of differentially methylated gene Sl DET1 or Sl PDS resulted in unusual brown pigmentation in Cnr fruits.These results suggest that comparative WGBS coupled with VIGS can be used to identify genes that may contribute to the colourless unripe phenotype of fruit in the Cnr epimutant. | Weiwei Chen Zhiming Yu Junhua Kong Hui Wang Yichen Li Mei Zhao Xiaohong Wang Qianqian Zheng Nongnong Shi Pengcheng Zhang Silin Zhong Paul Hunter Mahmut Tor Yiguo Hong | 2018 | Science China(Life Sciences)2018，61，2： | 3 |
| 19 | Cavitation Erosion Corrosion Behaviour of Manganese-nickel-aluminum Bronze in Comparison with Manganese-brass显示文摘The cavitation erosion corrosion behaviour of ZQMn12-8-3-2 manganese-nickel-aluminum bronze and ZHMn55-3-1 manganese-brass was investigated by mass loss, electrochemical measurements (polarization curves and electrochemical impedance spectroscopy) and the cavitation damaged surfaces were observed by scanning electron microscopy (SEM). The results showed that ZQMn12-8-3-2 had better cavitation erosion resistance than ZHMn55-3-1. After the cavitation erosion for 6 h, the cumulative mass loss of ZQMn12-8-3-2 was about 1/3 that of ZHMn55-3-1. The corrosion current density of ZQMn12-8-3-2 was less than that of ZHMn55-3-1 under both static and cavitaiton condition. The free-corrosion potentials of ZQMn12-8-3-2 and ZHMn55-3-1 were all shifted in positive direction under cavitation condition compared to static condition. In the total cumulative mass loss under cavitation condition, the pure erosion played a key role for the two tested materials (74% for ZHMn55-3-1 and 60% for ZQMn12-8-3-2), and the total synergism between corrosion and erosion of ZQMn12-8-3-2 (39%) was larger than that of ZHMn55-3-1 (23%). The high cavitation erosion resistance of ZQMn12-8-3-2 was mainly attributed to its lower stacking fault energy (SFE), the higher microhardness and work-hardening ability as well as the favorable propagation of cavitation cracks for ZQMn12-8-3-2, i.e., parallel to the surface rather than perpendicular to the surface for ZHMn55-3-1. | Hong Yu Yugui Zheng Zhiming Yao | 2009 | Journal of Materials Science & Technology2009，25，6： | 3 |
| 20 | Optimized statistical analysis of software trustworthiness attributes显示文摘Software trustworthiness has become one of the key restrictions for software service quality and the development of the software industry.However,trustworthiness attributes interlace structured and dynamical coupling relations,which causes great barriers for trustworthiness measurements of large-scale software.According to the dynamical evolutionary characteristics of software trustworthiness attributes,this paper proposes a new approach for optimizing the trustworthiness measurement in terms the kernel trustworthiness attributes,and improves a downsize-optimized statistical analysis method for software trustworthiness attributes based on their nonlinear relations.The improved method considerably simplifies the trustworthiness assessment of largescale software.Using theoretical analysis and numerical simulations,the feasibility of this method is verified using two typical examples that illustrate the realization of the trustworthiness measurement. | ZHANG Xiao LI Wei ZHENG ZhiMing GUO BingHui | 2012 | Science China(Information Sciences)2012，55，11： | 3 |
