| 3 | Vibration analysis of atomic force microscope cantilevers in contact resonance force microscopy using Timoshenko beam model显示文摘Timoshenko beam model is employed to investigate the vibration of atomic force microscope(AFM)cantilevers in contact resonance force microscopy(CRFM).Characteristic equation with both vertical and lateral tip-sample contact is derived.The contact resonance frequencies(CRFs)obtained by the Timoshenko model are compared with those by the Euler-Bernoulli model.A method is proposed to correct the wave number obtained by the Euler-Bernoulli model.The forced vibration is compared between the two models.Results reveal that the Timoshenko model is superior to the Euler-Bernoulli model in predicting the vibration characteristics for cantilevers’higher eigenmodes. | Xilong Wen,Pengfei Li,Faxin | 2017 | Acta Mechanica Solida Sinica2017，30，5： | 0 |
| 4 | Research on Subject Nature and Objective of Physical Education Training显示文摘Physical education and training is considered as a new subject among the same type of discipline.It has a short history background and is relatively young.However,the influence of the discipline of physical education and training must not be ignored by simply blaming it as the youngest discipline.In addition,especially in the case of rapid economic development and rapid improvement in living standards today,the influence of this discipline is relatively strong.Therefore,this thesis mainly studies the subject nature and object of physical education training.The research object of this subject can be studied from three key points,such as:the curriculum of the subject,the research method and the research of the subject of education.The comprehensive development of physical education and physical education is a comprehensive discipline. | Pengfei Wen Menghua Wang | 2019 | Journal of Contemporary Educational Research2019，3，6： | 0 |

| 6 | Comparison of Different Excitation Schemes in Bimodal Atomic Force Microscopy in Air and Liquid Environments显示文摘Bimodal amplitude modulation atomic force microscopy(AM-AFM)is widely used in nanoscale topography and compositional contrast imaging for various materials.In this work,we use computational simulation to compare the dynamic behaviors of AFM cantilevers in three commonly used excitation schemes in bimodal AM-AFM,i.e.,the cantilever base excitation,the cantilever end excitation,and the uniform excitation along the length of the cantilever,in both air and liquid environments.The amplitude and phase spectroscopy curves and the frequency responses acquired from the three excitation schemes are compared and discussed.The results would be useful in guiding the selection of excitation methods and the optimization of imaging conditions. | Zhenyang Huang Pengfei Wen Xilong Zhou | 2021 | Acta Mechanica Solida Sinica2021，34，2： | 1 |

| 17 | Determining the optimum economic insulation thickness of double pipes buried in the soil for district heating systems显示文摘The insulation thickness(IT)of double pipes buried in the soil(DPBIS)for district heating(DH)systems was optimized to minimize the annual total cost of DPBIS for DH systems.An optimization model to obtain the optimum insulation thickness(OIT)and minimum annual total cost(MATC)of DPBIS for DH systems was established.The zero point theorem and fsolve function were used to solve the optimization model.Three types of heat sources,four operating strategies,three kinds of insulation materials,seven nominal pipe size(NPS)values,and three buried depth(BD)values were considered in the calculation of the OIT and MATC of DPBIS for DH systems,respectively.The optimization results for the above factors were compared.The results show that the OIT and MATC of DPBIS for DH systems can be obtained by using the optimization model.Sensitivity analysis was conducted to investigate the impact of some economic parameters,i.e.,unit heating cost,insulation material price,interest rate,and insulation material lifetime,on optimization results.It is found out that the impact of sensitivity factors on the OIT and MATC of DPBIS for DH systems is different. | Fating LI Pengfei JIE Zhou FANG Zhimei WEN | 2021 | Frontiers in Energy2021，15，1： | 0 |
| 18 | χ(^(2)) nonlinear photonics in integrated microresonators显示文摘Second-order(χ^((2))) optical nonlinearity is one of the most common mechanisms for modulating and generating coherent light in photonic devices.Due to strong photon confnement and long photon lifetime,integrated microresonators have emerged as an ideal platform for investigation of nonlinear optical efects.However,existing silicon-based materials lack a χ^((2)) response due to their centrosymmetric structures.A variety of novel material platforms possessing χ^((2)) nonlinearity have been developed over the past two decades.This review comprehensively summarizes the progress of second-order nonlinear optical efects in integrated microresonators.First,the basic principles of χ^((2)) nonlinear efects are introduced.Afterward,we highlight the commonly used χ^((2)) nonlinear optical materials,including their material properties and respective functional devices.We also discuss the prospects and challenges of utilizing χ^((2)) nonlinearity in the feld of integrated microcavity photonics. | Pengfei Liu Hao Wen Linhao Ren Lei Shi Xinliang Zhang | 2023 | Frontiers of Optoelectronics2023，16，3： | 0 |
| 19 | Effect of Point Cloud Data Simplification and Encryption on Micro-Topography Data Analysis显示文摘Simplification and encryption are performed on the point cloud data concerning high-relief( 20 cm tillage) and low-relief( raking bare slope) terrain on a different scale of observation. We select three indicators( surface curvature,slope aspect and surface roughness) to evaluate the effect of simplification and encryption on micro-topography data analysis. The results show that simplification and encryption have a significant impact on the curvature of high-relief terrain,but have no significant impact on low-relief terrain. The slope aspect change is not significant after 5,10 mm data simplification and encryption; 1 mm simplification has a regular impact on surface roughness; 5 mm encryption and simplification have a complex impact on high-relief terrain; 10 mm encryption has a complex impact on high-relief terrain roughness change but a regular impact on bare slope change. | Zhou WEI Pengfei WEN Jiong JIANG Xian JI Zhenjia HE | 2016 | Asian Agricultural Research2016，8，10： | 0 |
| 20 | High-efficient energy saving processing of big data of communication under mobile cloud computing显示文摘From 21st century,it is hard for traditional storage and algorithm to provide service with high quality because of big data of communication which grows rapidly.Thus,cloud computing technology with relatively low cost of hardware facilities is created.However,to guarantee the quality of service in the situation of the rapid growth of data volume,the energy consumption cost of cloud computing begins to exceed the hardware cost.In order to solve the problems mentioned above,this study briefly introduced the virtual machine and its energy consumption model in the mobile cloud environment,introduced the basic principle of the virtual machine migration strategy based on the artificial bee colony algorithm and then simulated the performance of processing strategy to big data of communication based on artificial bee colony algorithm in mobile cloud computing environment by CloudSim3.0 software,which was compared with the performance of two algorithms,resource management(RM)and genetic algorithm(GA).The results showed that the power consumption of the migration strategy based on the artificial bee colony algorithm was lower than the other two strategies,and there were fewer failed virtual machines under the same number of requests,which meant that the service quality was higher. | Yazhen Liu Pengfei Fan Jiyang Zhu Liping Wen Xiongfei Fan | 2019 | International Journal of Modeling, Simulation, and Scientific Computing2019，10，4： | 0 |
