| 1 | NUMERICAL STUDIES ON RESONANT AND ENHANCEMENT EFFECTS FOR COUPLING OF MICROWAVE PULSES INTO NARROW SLOTS显示文摘In this paper, modifications to the finite-difference time-domain(FD-TD) method for modeling microwave pulse coupling into a slot, which is much narrower than one conventional FD-TD cell, are discussed. The coupling process of microwave pulse into a slot is studied by using the modified FD-TD method, and the dependence of microwave coupling on slot sizes, the carrier frequencies and the polarization directions of the incident waves is analysed. Resonant and enhancement effects which occur in this process are observed. The condition at which the resonant effect takes place is also presented. | Wang Jianguo Yu Hanqing Liu Guozhi Chen Yusheng Fan Ruyu (Northwest Institute of Nuclear Technology, Branch 15, P. O.

| 2 | Coupling Effect of Heat Transfer and Flow Resistance in the Rifled Tube Water Wall of a Ultra-Supercritical CFB Boiler显示文摘The coupling factor is used in this study to characterise the combined effect of the heat transfer and resistance characteristics of a rifled tube. Boundary layer theory is utilised to investigate the relationship between the comprehensive coefficient and Reynolds number in two regions, namely, higher and lower than pseudo-critical enthalpy. Results indicate that mass flux exerts a decisive negative influence on the coupling effect, and the impacts of pressure and heat flux are weak. The overall effect decreases rapidly as the mass flux increases, but it increases in the area behind the quasi-critical enthalpy. The coupling effect is also affected by specific heat ratio, thermal acceleration and buoyancy. The correlations of heat transfer and friction resistance are deduced with high precision according to experimental data. | LI Yaode YANG Dong OUYANG Shijie LIU Dan WANG Wenyu | 2019 | Journal of Thermal Science2019，28，5： | 5 |
| 3 | Plasmon-exciton interaction in colloidally fabricated metal nanoparticlequantum emitter nanostructures显示文摘When quantum emitters and plasmonic nanoparticles are in close vicinity,the energy exchange,termed as plasmon-exciton coupling,can make the absorption and emission behavior of the hybrid structure very different from those of the two constituents alone.The coupling strength between the two constituents highly depends on how the hybrid structure is constructed.As a result,a diverse range of coupling effect arise including plasmon induced fluorescence quenching/enhancing (weak coupling),Fano interference (intermediate coupling),Rabi-splitting and lasing (strong coupling).The emergence of different coupling behavior can be controlled by the different combinations of quantum emitters and plasmonic nanoparticles as well as the spatial arrangement of the individual components.Colloidal assembly/synthesis methods are essentially delicate strategies that can build the hybrid nanostructures with nanometer precision and allow for large-scale processing.In this review,we discuss the theoretical models that apply to different coupling behaviors,the optical properties of the hybrid systems,and the advancement of colloidal methods to manipulate the plasmon-exciton in the hybrid structures.We also provide perspectives on the challenges and future directions of the research in coupled plasmon-exciton nanosystems. | Yi Luo Jing Zhao | 2019 | Nano Research2019，12，9： | 3 |
| 4 | WAVE-SOIL-PIPE COUPLING EFFECT ON SUBMARINE PIPELINE ON-BOTTOM STABILITY显示文摘Wave-soil-pipe coupling effect on the untrenched pipeline stability onsands is for the first time investigated experimentally. Tests are conducted in the U-shaped water tunnel, which generates an oscillatory flow, simulating the water particlemovements with periodically changing direction under the wave action. Characteristictimes and phases during the instability process are revealed. Linear relationshipbetween Froude number and non-dimensional pipe weight is obtained. Effects ofinitial embedment and loading history are observed. Test results between the wave-soil-pipe interaction and pipe-soil interaction under cyclic mechanical loading arecompared. The mechanism is briefly discussed. For applying in the practical design,more extensive and systematic investigations are needed. | 顾小芸 高福平 浦群 | 2001 | Acta Mechanica Sinica2001，17，1： | 3 |

| 6 | Coupling between the Grain for Green Program and a household level-based agricultural eco-economic system in Ansai,Shaanxi Province of China显示文摘The implementation of the Grain for Green Program(GGP)has changed the development track of the agricultural eco-economic system in China.In response to the results of a lag study that investigated the coupling between the GGP and the agricultural eco-economic system in a loess hilly region,we used a structural equation model to analyze the survey data from 494 households in Ansai,a district of Yan’an City in Shaanxi Province of China in 2015.The model clarified the direction and intensity of the coupling between the GGP and the agricultural eco-economic system.The coupling benefits were derived through linkages between the program and various chains in the agricultural eco-economic system.The GGP,the agroecosystem of Ansai and their potential coupling effects were in a state of general coordination.The agroecosystem directly affected the coupling effect,with the standardized path coefficient of 0.87,indicating that the agroecosystem in Ansai at this stage provided basic material support for the coupling between the GGP and the agricultural eco-economic system.The direct path coefficient of agroeconomic system impacted on the coupling effect was-0.76,indicating that partial contradictions occurred between the agroeconomic system and the coupling effect.Therefore,although the current agroecosystem in Ansai should be provided sufficient agroecological resources for the benign coupling between the program and the agricultural eco-economic system,agricultural development failed to effectively transform agroecological resources into agricultural economic advantages in this region,which resulted in a relative lag in the development of the agricultural economic system.Thus,the coupling between the GGP and the agricultural eco-economic system was poor.To improve the coupling and the sustainable development of the agricultural eco-economic system in cropland retirement areas,the industrial structure needs to be diversified,the agricultural resources(including agroecological resources,agricultural economic resources and agricultural social resources)need to be rationally allocated,and the chain structure of the agricultural eco-economic system needs to be continuously improved. | LI Yue WANG Jijun HAN Xiaojia GUO Mancai CHENG Simin QIAO Mei ZHAO Xiaocui | 2020 | Journal of Arid Land2020，12，2： | 2 |

| 8 | Upper Bound Solution of Soil Slope Stability under Coupling Effect of Rainfall and Earthquake显示文摘Based on the limit analysis upper bound method,a new model of soil slope collapse has been proposed which consists of two rigid block zones and a plastic shear zone.Soil slope was induced failure by coupling effect of rainfall and earthquake,and these blocks were also incorporated horizontal earthquake force and vertical gravitate.The velocities and forces were analyzed in three blocks,and the expression of velocity discontinuities was obtained by the principle of incompressibility.The external force work for the blocks,the internal energy of the plastic shear zone and the velocity discontinuous were solved.The present stability ratios are compared to the prevenient research,which shows the superiority of the mechanism and rationality of the analysis.The critical height of the soil slope can provide theoretical basis for slope support and design. | 尹小军 王兰民 | 2019 | Journal of Donghua University(English Edition)2019，36，4： | 1 |

| 10 | Numerical analysis of thermal impact on hydro-mechanical properties of clay显示文摘As is known,high-level radioactive waste(HLW) is commonly heat-emitting.Heat output from HLW will dissipate through the surrounding rocks and induce complex thermo-hydro-mechanical-chemical(THMC) processes.In highly consolidated clayey rocks,thermal effects are particularly significant because of their very low permeability and water-saturated state.Thermal impact on the integrity of the geological barriers is of most importance with regard to the long-term safety of repositories.This study focuses on numerical analysis of thermal effects on hydro-mechanical properties of clayey rock using a coupled thermo-mechanical multiphase flow(TH2M) model which is implemented in the finite element programme OpenGeoSys(OGS).The material properties of the numerical model are characterised by a transversal isotropic elastic model based on Hooke's law,a non-isothermal multiphase flow model based on van Genuchten function and Darcy's law,and a transversal isotropic heat transport model based on Fourier's law.In the numerical approaches,special attention has been paid to the thermal expansion of three different phases:gas,fluid and solid,which could induce changes in pore pressure and porosity.Furthermore,the strong swelling and shrinkage behaviours of clayey material are also considered in the present model.The model has been applied to simulate a laboratory heating experiment on claystone.The numerical model gives a satisfactory representation of the observed material behaviour in the laboratory experiment.The comparison of the calculated results with the laboratory findings verifies that the simulation with the present numerical model could provide a deeper understanding of the observed effects. | Xuerui Wang Hua Shao Jürgen Hesser Chunliang Zhang Wenqing Wang Olaf Kolditz | 2014 | Journal of Rock Mechanics and Geotechnical Engineering2014，6，5： | 0 |

| 12 | Electric field tuning of the anomalous Hall effect at oxide interfaces显示文摘Anomalous Hall effect is the phenomenon where the transport properties of the spin-polarized electrons are governed by the spinorbit coupling that couples the orbital and spin degrees of freedom of the electron.Here we show that the anomalous Hall effect at a magnetic interface with strong spin-orbit coupling can be tuned with an external electric field.By altering the strength of the inversion symmetry breaking,the electric field changes the Rashba interaction,which in turn modifies the magnitude of the Berry curvature,the central quantity in determining the anomalous Hall conductivity.The effect is illustrated with a square lattice model,which yields a quadratic dependence of the anomalous Hall conductivity for small electric fields.Explicit density-functional calculations were performed for the recently grown iridate interface,viz.,the(SrIrO_(3))1/(SrMnO_(3))1(001)structure,both with and without an electric field,which show a strong electric field dependence.The effect may be potentially useful in spintronics applications. | Sayantika Bhowal Sashi Satpathy | 2019 | npj Computational Materials2019，，1： | 0 |
| 13 | Structure and magnetic properties of nanocrystalline ferromagnets (Ⅱ)——Magnetoelastic coupling effects显示文摘The role of magnetoelastic coupling effects in nanocrystalline ferromagnets is investigated by means of high-field magnetization and Doppler-broadening spectrum measurements. For the nanocrystalline Fe73.5 Cu1Nb3-Si13 5B9 alloy, the results show that the pinning effects resulting from the quasidislocation dipole intensely influence the movement of domain wall; by coupling with the magnetostriction the defects-induced stress fields determine the magnetic properties at the early stage of crystallization. In view of the effective anisotropy and magnetoelastic coupling energy the optimal annealing conditions of alloys are discussed. | 刘涛 徐祖雄 赵钟涛 马如璋 胡天斗 谢亚宁 郭应焕 | 1997 | Science China Mathematics1997，40，4： | 0 |
| 14 | High-Sensitivity Tunnel Magnetoresistance Sensors Based on Double Indirect and Direct Exchange Coupling Effect显示文摘Detection of ultralow magnetic field requires magnetic sensors with high sensitivity and low noise level,especially for low operating frequency applications.We investigated the transport properties of tunnel magnetoresistance(TMR)sensors based on the double indirect exchange coupling effect.The TMR ratio of about 150%was obtained in the magnetic tunnel junctions and linear response to an in-plane magnetic field was successfully achieved.A high sensitivity of 1.85%/Oe was achieved due to a designed soft pinned sensing layer of CoFeB/NiFe/Ru/IrMn.Furthermore,the voltage output sensitivity and the noise level of 10.7 mV/V/Oe,10 nT/Hz^(1/2)at 1 Hz and3.3 nT/Hz^(1/2)at 10 Hz were achieved in Full Wheatstone Bridge configuration.This kind of magnetic sensors can be used in the field of smart grid for current detection and sensing. | 韩秀峰 张雨 王翼展 黄黎 马勤礼 刘厚方 万蔡华 韦家峰 尹林 于国强 余天 闫羽 | 2021 | Chinese Physics Letters2021，38，12： | 0 |

| 16 | Model of NBTI combined with mobility degradation显示文摘The mobility degradation induced by negative bias temperature instability(NBTI) is usually ignored in traditional NBTI modeling and simulation, resulting in overestimation of the circuit lifetime, especially after longterm operation. In this paper, the mobility degradation is modeled in combination with the universal NBTI model.The coulomb scattering induced by interface states is revealed to be the dominant component responsible for mobility degradation. The proposed mobility degradation model fits the measured data well and provides an accurate solution for evaluating coupling of NBTI with HCI(hot carrier injection) and SHE(self-heating effect), which indicates that mobility degradation should be considered in long-term circuit aging simulation. | Xuezhong Wu Chenyue Ma Shucheng Gao Xiangbin Li Fu Sun Lining Zhang Xinnan Lin | 2018 | Journal of Semiconductors2018，39，12： | 0 |
| 17 | Phase-Locking Diffusive Skin Effect显示文摘We explore the exceptional point(EP)induced phase transition and amplitude/phase modulation in thermal diffusion systems.We start from the asymmetric coupling double-channel model,where the temperature field is unbalanced in the amplitude and locked in the symmetric phase.By extending into the one-dimensional tight-binding non-Hermitian lattice,we study the convection-driven phase locking and the asymmetric-couplinginduced diffusive skin effect with the high-order EPs in static systems.Combining convection and asymmetric couplings,we further show the phase-locking diffusive skin effect.Our work reveals the mechanism of controlling both the amplitude and phase of temperature fields in thermal coupling systems and has potential applications in non-Hermitian topology in thermal diffusion. | 曹培超 彭玉桂 李鹰 祝雪丰 | 2022 | Chinese Physics Letters2022，39，5： | 0 |

| 20 | Study on Vulnerability of Concrete Filled Steel Tube Frame-Buckling- Resistant Bracing Structure System under Wind and Earthquake Coupling显示文摘Engineering structures will inevitably be affected by various disasters such as wind or earthquake during their whole service life. Taking the concrete-filled steel tube frame-buckling-restrained brace structure system as the research object, the wind speed time histories at different heights of the structure with recurrence periods of 1 year, 10 years and 50 years are simulated. Based on the OpenSees finite element software, the nonlinear dynamic time history analysis of the structure under four working conditions of earthquake single action and wind-earthquake coupling action with recurrence periods of 1 year, 10 years and 50 years respectively is carried out, and the vulnerability curves of the structure under different working conditions are generated based on the seismic demand analysis method. The results show that with the increase of wind action, the structural response and vulnerability have an increasing trend. However, with the increase of ground motion intensity, the influence of wind on structural vulnerability gradually decreases. | Yongjun Xu | 2019 | Smart Construction Research2019，3，1： | 0 |
