| 1 | Simulation of influence of multi-defects on long-term working performance of high arch dam显示文摘As an integrated structure,an arch dam is assumed to bear loads in its design consideration.However,multi-defects,such as cracks and the opening of transverse joints,are unavoidable during construction and operation.Multi-defects will reduce the structural integrity and stiffness of the dam and affect its working performance and degree of safety.In the current paper,a numerical model of defects and a simulation method of a high arch dam are introduced.The Chencun arch dam is analyzed as a case study.An entire course simulation analysis of the Chencun arch dam from construction to operation is carried out,through which the opening of the transverse and longitudinal joints,formation of cracks,and their influence on deformation and stress of the dam are studied.According to the results of the analysis,appropriate measures should be adopted to prevent the development of cracks,and observation should be strengthened for a more timely discovery of risks. | ZHANG GuoXin ,LIU Yi,ZHENG CuiYing & FENG Fan State Key Laboratory of Simulation and Regulation of Water Cycle in River Basin,Beijing 100038,China China Institute of Water Resources and Hydropower Research,Beijing 100038,China | 2011 | Science China(Technological Sciences)2011，54，S1： | 17 |
| 2 | Accelerated anaerobic dechlorination of DDT in slurry with Hydragric Acrisols using citric acid and anthraquinone-2,6-disulfonate(AQDS)显示文摘The application of electron donor and electron shuttle substances has a vital influence on electron transfer,thus may affect the reductive dechlorination of 1,1,1-trichoro-2,2-bis(p-chlorophenyl)ethane(DDT) in anaerobic reaction systems.To evaluate the roles of citric acid and anthraquinone-2,6-disulfonate(AQDS) in accelerating the reductive dechlorination of DDT in Hydragric Acrisols that contain abundant iron oxide,a batch anaerobic incubation experiment was conducted in a slurry system with four treatments of(1) control,(2) citric acid,(3) AQDS,and(4) citric acid + AQDS.Results showed that DDT residues decreased by 78.93%–92.11% of the initial quantities after 20 days of incubation,and 1,1-dichloro-2,2-bis(4-chlorophenyl)-ethane(DDD) was the dominant metabolite.The application of citric acid accelerated DDT dechlorination slightly in the first 8 days,while the methanogenesis rate increased quickly,and then the acceleration effect improved after the 8th day while the methanogenesis rate decreased.The amendment by AQDS decreased the Eh value of the reaction system and accelerated microbial reduction of Fe(III) oxides to generate Fe(II),which was an efficient electron donor,thus enhancing the reductive dechlorination rate of DDT.The addition of citric acid + AQDS was most efficient in stimulating DDT dechlorination,but no significant interaction between citric acid and AQDS on DDT dechlorination was observed.The results will be of great significance for developing an efficient in situ remediation strategy for DDT-contaminated sites. | Cuiying Liu Xianghua Xu Jianling Fan | 2015 | Journal of Environmental Sciences2015，27，12： | 5 |
| 3 | SINGULAR BEHAVIORS OF INTERFACIAL CRACKS IN 2D MAGNETOELECTROELASTIC BIMATERIALS显示文摘The singular characteristics of stress,electric displacement and magnetic induction fields near the tip of impermeable interfacial cracks in two-dimensional magnetoelectroelastic bimaterials are studied using the generalized Stroh formalism.Two types of singularities are ob-tained:one is the oscillating singularity 1/2±iε,the other is the non-oscillating singularity 1/2±κ.It is found that the non-zero parameters ε and κ cannot coexist for one transversely isotropic MEE bimaterial,a similar result is obtained for transversely isotropic piezoelectric bimaterials. | Cuiying Fan Youhe Zhou Han Wang Minghao Zhao | 2009 | Acta Mechanica Solida Sinica2009，22，3： | 5 |
| 4 | High efficiency production of ginsenoside compound K by catalyzing ginsenoside Rb1 using snailase显示文摘The rare ginsenoside Compound K(C-K) is attracting more attention because of its good physiological activity and urgent need. There are many pathways to obtain ginsenoside C-K, including chemical and biological methods. Among these, the conversion of PPD-type ginsenosides by enzymatic hydrolysis is a trend due to its high efficiency and mild conditions. For effectively extracting from the other panaxadiol saponins, the conversion process for ginsenoside C-K was investigated using snailases in this study. The univariate experimental design and response surface methodology were used to determine the optimal hydrolysis conditions for the conversion of ginsenoside Rb1 into ginsenoside C-K by snailases. The optimum conditions were as follows: p H 5.12, temperature 51 °C, ratio of snailase/substrate 0.21, and reaction time 48 h. On the basis of these parameters, the addition of 1.0 mmol·L^(-1) ferric ion was found to significantly improve the enzymolysis of snailases for the first time. With the above conditions, the maximum conversion rate reached 89.7%, suggesting that the process can obviously increase the yield of ginsenoside C-K. The bioassay tests indicated that the ginsenoside C-K showed anti-tumor activity in a series of tumor cell lines. Based on these results, we can conclude that the process of rare ginsenoside CK production by enzymolysis with snailase is feasible, efficient, and suitable for the industrial production and application. | Zhiguang Duan Chenhui Zhu Jingjing Shi Daidi Fan Jianjun Deng Rongzhan Fu Rong Huang Cuiying Fan | 2018 | Chinese Journal of Chemical Engineering2018，26，7： | 5 |

| 8 | Dielectric Breakdown Model for an Electrically Semi-Permeable Penny-Shaped Crack in Three-Dimensional Piezoelectric Media显示文摘The dielectric breakdown(DB) model for a penny-shaped crack under a semipermeable boundary condition in a three-dimensional piezoelectric medium is studied.An approximate analytical solution is derived by using the boundary integral equation with extended displacement discontinuity,and the corresponding boundary element method with double iterative approaches is developed to analyze the semi-permeable crack.The effect of electric boundary conditions on crack faces is discussed on the basis of DB model.By comparing the DB model with the polarization saturation(PS) model for different piezoelectric materials,some interesting phenomena related to the electric yielding zone and local J-integral are observed. | Minghao Zhao Huayang Dang Guangtao Xu Cuiying Fan | 2016 | Acta Mechanica Solida Sinica2016，29，5： | 1 |

| 11 | Thermal-induced interfacial behavior of a thin one-dimensional hexagonal quasicrystal film显示文摘In this paper,we investigate the interfacial behavior of a thin one-dimensional(1D)hexagonal quasicrystal(QC)film bonded on an elastic substrate subjected to a mismatch strain due to thermal variation.The contact interface is assumed to be nonslipping,with both perfectly bonded and debonded boundary conditions.The Fourier transform technique is adopted to establish the integral equations in terms of interfacial shear stress,which are solved as a linear algebraic system by approximating the unknown phonon interfacial shear stress via the series expansion of the Chebyshev polynomials.The expressions are explicitly obtained for the phonon interfacial shear stress,internal normal stress,and stress intensity factors(SIFs).Finally,based on numerical calculations,we briefly discuss the effects of the material mismatch,the geometry of the QC film,and the debonded length and location on stresses and SIFs. | Huayang DANG Dongpei QI Minghao ZHAO Cuiying FAN C.S.LU | 2023 | Applied Mathematics and Mechanics(English Edition)2023，44，5： | 0 |
| 12 | Interfacial fracture analysis for a two-dimensional decagonal quasi-crystal coating layer structure显示文摘The interface crack problems in the two-dimensional(2D)decagonal quasicrystal(QC)coating are theoretically and numerically investigated with a displacement discontinuity method.The 2D general solution is obtained based on the potential theory.An analogy method is proposed based on the relationship between the general solutions for 2D decagonal and one-dimensional(1D)hexagonal QCs.According to the analogy method,the fundamental solutions of concentrated point phonon displacement discontinuities are obtained on the interface.By using the superposition principle,the hypersingular boundary integral-differential equations in terms of displacement discontinuities are determined for a line interface crack.Further,Green’s functions are found for uniform displacement discontinuities on a line element.The oscillatory singularity near a crack tip is eliminated by adopting the Gaussian distribution to approximate the delta function.The stress intensity factors(SIFs)with ordinary singularity and the energy release rate(ERR)are derived.Finally,a boundary element method is put forward to investigate the effects of different factors on the fracture. | Minghao ZHAO Cuiying FAN C.S.LU Huayang DANG | 2021 | Applied Mathematics and Mechanics(English Edition)2021，42，11： | 0 |
| 13 | Three-dimensional interfacial fracture analysis of a one-dimensional hexagonal quasicrystal coating显示文摘In this paper, the three-dimensional(3D) interfacial fracture is analyzed in a one-dimensional(1D) hexagonal quasicrystal(QC) coating structure under mechanical loading. A planar interface crack with arbitrary shape is studied by a displacement discontinuity method. Fundamental solutions of interfacial concentrated displacement discontinuities are obtained by the Hankel transform technique, and the corresponding boundary integral-differential equations are constructed with the superposition principle.Green’s functions of constant interfacial displacement discontinuities within a rectangular element are derived, and a boundary element method is proposed for numerical simulation.The singularity of stresses near the crack front is investigated, and the stress intensity factors(SIFs) as well as energy release rates(ERRs) are determined. Finally, relevant influencing factors on the fracture behavior are discussed. | Xin ZHANG Minghao ZHAO Cuiying FAN C.S.LU Huayang DANG | 2022 | Applied Mathematics and Mechanics(English Edition)2022，43，12： | 0 |
| 14 | Enhanced anaerobic degradation of hexachlorobenzene in a Hydragric Acrisol using humic acid and urea显示文摘Humic substances acting as an electron shuttle and nitrogen transformation process influence remarkably the electron transfer in anaerobic reaction systems and thus may affect the reductive dechlorination of hexachlorobenzene(HCB). In order to develop an efficient agricultural strategy for the remediation of organochlorine-contaminated soils, a batch incubation experiment was conducted to study the effects of humic acid, urea, and their interaction on the reductive dechlorination of HCB in a Hydragric Acrisol with high iron oxide content. After 44 d of anaerobic incubation, the five treatments, sterile control,control, humic acid, urea, and humic acid + urea decreased HCB residues by 28.8%, 47.8%, 64.7%, 57.8%, and 71.3%, respectively. The amendment of humic acid or urea significantly decreased soil Eh values and accelerated Fe(Ⅲ) reduction to Fe(Ⅱ), thus promoting markedly reductive dechlorination of HCB. Humic acid had a larger dechlorination effect than urea. Since there was a synergistic interaction between humic acid and urea that accelerated HCB dechlorination, the treatment having both amendments together was the most efficient for HCB dechlorination. The results showed that the combination of NH4^(+)_(-)N supplied by a fertilizer and humic substance is a feasible strategy for the remediation of organochlorine-contaminated soils with abundant iron oxide. | Cuiying LIU Jianling FAN Xianghua xu Yu Wu | 2021 | Pedosphere2021，31，1： | 0 |
| 15 | Ce and Se co-doped MBG/SA/HLC microgel bone powder for repairing tumor bone defects显示文摘The repair and treatment of tumor bone defects is a difficult problem to solve urgently in clinical medicine.After tumor resection,patients are not only faced with a large area of bone defect,but also may have the risk of tumor recurrence,which can easily cause huge physical and mental harm to patients.In this study,we successfully designed and constructed an organic/inorganic composite microgel bone powder(S-H-M3%Ce/3%Se)based on cerium(Ce)and selenium(Se)elements co-doped mesoporous bioactive glass(M3%Ce/3%Se),sodium alginate(SA),and recombinant human-like collagen(HLC).The obtained S-H-M3%Ce/3%Se could inhibit the growth of osteoma cells and promote the growth of normal cells,and effectively promote the repair of defect bone.The integration of the“treatment and repair”organic/inorganic composite microgel bone powder provided a new strategy for the treatment of cancerous bone defects. | Miaolin Fan Wan Liu Cuiying Fan Xiaoyan Zheng Junfeng Hui Chaoquan Hu Daidi Fan | 2023 | Nano Research2023，16，1： | 0 |
