| 2 | Lightweight Design of Automobile Drive Shaft Based on the Characteristics of Low Amplitude Load Strengthening显示文摘There are two kinds of internationally recognized approaches in terms of lightweight design.One is based on fatigue accumulated damage theory to achieve better reliability by optimal structural design;another is to use high performance lightweight materials.The former method takes very few considerations on the structural strengthening effects caused by the massive small loads in service.In order to ensure safety,the design is usually conservative,but the strength potential of the component is not fully exerted.In the latter method,cost is the biggest obstacle to lightweight materials in automotive applications.For the purpose of light weighting design on a fuel cell vehicle,the new design method is applied on drive shafts.The method is based on the low amplitude load strengthening characteristics of the material,and allows the stress,corresponding to test load,to enter into the strengthened range of the material.Under this condition,the light weighting design should assure that the reliability of the shaft is not impaired,even maximizes the strength potential of machine part in order to achieve the weight reduction and eventually to reduce the cost.At last,the feasibility of the design is verified by means of strength analysis and modal analysis based on the CAD model of light weighted shaft.The design applies to the load case of half shaft in independent axle,also provides technological reference for the structural lightweight design of vehicles and other machineries. | ZHENG Songlin XU Honghui FENG Jinzhi ZHENG Zuanxi WANG Youtao LU Leilei | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 16 |
| 3 | Numerical Simulation and Experimental Study of Heat-fluid-solid Coupling of Double Flapper-nozzle Servo Valve显示文摘The double flapper-nozzle servo valve is widely used to launch and guide the equipment. Due to the large instantaneous flow rate of servo valve working under specific operating conditions, the temperature of servo valve would reach 120℃ and the valve core and valve sleeve deform in a short amount of time. So the control precision of servo valve significantly decreases and the clamping stagnation phenomenon of valve core appears. In order to solve the problem of degraded control accuracy and clamping stagnation of servo valve under large temperature difference circumstance, the numerical simulation of heat-fluid-solid coupling by using finite element method is done. The simulation result shows that zero position leakage of servo valve is basically impacted by oil temperature and change of fit clearance. The clamping stagnation is caused by warpage-deformation and fit clearance reduction of the valve core and valve sleeve. The distribution rules of the temperature and thermal-deformation of shell, valve core and valve sleeve and the pressure, velocity and temperature field of flow channel are also analyzed. Zero position leakage and electromagnet's current when valve core moves in full-stroke are tested using Electro-hydraulic Servo-valve Characteristic Test-bed of an aerospace sciences and technology corporation. The experimental results show that the change law of experimental current at different oil temperatures is roughly identical to simulation current. The current curve of the electromagnet is smooth when oil temperature is below 80℃, but the amplitude of current significantly increases and the hairy appears when oil temperature is above 80℃. The current becomes smooth again after the warped valve core and valve sleeve are reground. It indicates that clamping stagnation is caused by warpage-deformation and fit clearance reduction of valve core and valve sleeve. This paper simulates and tests the heat-fluid-solid coupling of double flapper-nozzle servo valve, and the obtained results provide the reference value for the design of double flapper-nozzle force feedback servo valve. | ZHAO Jianhua ZHOU Songlin LU Xianghui GAO Dianrong | 2015 | Chinese Journal of Mechanical Engineering2015，28，5： | 16 |
| 4 | Clue to a thorough understanding of terahertz pulse generation by femtosecond laser filamentation显示文摘In this work, it has been demonstrated that in order to fully understand the terahertz(THz) pulse generation process during femtosecond laser filamentation, the interaction between THz wave and air plasma has to be taken into account. This interaction is mainly associated with the spatial confinement of the THz pulse by the plasma column, which could be described by the one-dimensional negative dielectric(1DND) waveguide model. By combining the 1 DND model with the conventional four-wave mixing(4WM) and photocurrent(PC) models,the variation of THz spectral amplitude and width obtained in experiments could be better understood. Finally, a three-step procedure, with 1DND bridging 4WM and PC processes, has been established for the first time to describe the underlying mechanism of THz radiation from plasma sources. | JIAYU ZHAO WEIWEI LIU SHICHANG LI DAN LU YIZHU ZHANG YAN PENG YIMING ZHU SONGLIN ZHUANG | 2018 | Photonics Research2018，6，4： | 9 |
| 5 | Zircon Hf Isotopes and Geochemistry of the Early Paleoproterozoic High-Sr Low-Y Quartz-Diorite in the Quanji Massif,NW China:Crustal Growth and Tectonic Implications显示文摘The metamorphosed Early Paleoproterozoic granitoids in the Quanji massif,Northwestern China provide constraints for relationship between the Tarim Craton and North China Craton.Among granitoids batholiths,rocks of the Mohe quartz-diorite show typically adakitic geochemical characteristics,with medium K2O/Na2O ratios(0.56–1.17)and high Sr(519–619 ppm)low Y(9.37–20.40 ppm)and Yb(0.97–1.77 ppm)concentrations.The rocks haveεNd(t)values between+2.4and+4.4 and depleted mantle Nd model ages of 2.43–2.59 Ga.The magmatic zircons have positiveεHf(t)values ranging from+0.40 to+7.60 and depleted mantle Hf model ages of 2.43–2.70 Ga,with major peaks at^2.54 and^2.65 Ga.The geochemical and Nd-Hf isotopic characteristics indicate that the Mohe quartz-dioritic rocks might be formed by partial melting of high-pressure metamorphosed juvenile crustal rocks in post-orogenic extensional regime in the Early Paleoproterozoic.It suggests that important crustal growth occurred in the Quanji massif and the Tarim Craton at^2.4 and 2.5–2.7 Ga.The Quanji massif and Tarim Craton might share a similar crustal evolution history with the North China Craton in the Neoarchean. | Songlin Gong Nengsong Chen Hongyan Geng Min Sun Lu Zhang Qinyan Wang | 2014 | Journal of Earth Science2014，25，1： | 8 |
| 6 | Progress on design and related R&D activities for the water-cooled breeder blanket for CFETR显示文摘The water-cooled ceramic breeder (WCCB) blanket is one of the blanket candidates for Chinese fusion engineering testing reactor (CFETR) and is being developed at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). This paper reviews design and evolution of the WCCB blanket for CFETR, and presents a new WCCB blanket design according to the latest CFETR core parameters (major and minor radii are R = 7.2 m and a = 2.2 m, respectively) and missions. This new design is expected to satisfy multiple CFETR operation modes of 0.2, 0.5, 1.0, and 1.5 GW fusion power and achieve tritium self-sufficiency. The feasibility of the updated blanket design is evaluated from the aspects of neutronics and thermo-hydraulics. Furthermore, the research and development (R&D) activities supporting to the WCCB blanket for CFETR are reported, including the design code, the water loop experiments, the pebble bed modeling and experiments, and the components fabrication technology. | Songlin Liu Xiaoman Cheng Xuebin Ma Lei Chen Kecheng Jiang Xia Li Hui Bao Jichao Wang Wanjing Wang Changhong Peng Peng Lu Min Li Kai Huang | 2019 | Theoretical & Applied Mechanics Letters2019，9，3： | 6 |

| 10 | The theory of compression–shear coupled composite wave propagation in rock显示文摘The wave velocity analysis of rock medium is the main method used to explore the internal compositions in the crust and research seismic.In this paper,a compression–shear coupled nonlinear elastic constitutive relation is established,which is consistent with the mechanical properties of rock and mineral medium under high pressure.On this basis,numerical solutions of the wave equation and plane wave analytical solutions for the primary and secondary wave velocities are obtained.As is indicated by the comparison with the linear elastic constitutive theory,the results reflect the compression–shear coupling characteristics of the rock,including the stress path effect and the compression–shear coupling wave effect.With different parameter values,the velocity of the secondary wave changes from lower than that of the elastic shear wave,to higher than that of the elastic shear wave.The research results are expected to provide meaningful explanations for the physical mechanisms of the supershear wave and sub-Rayleigh wave,and guidance for the detection of rock and soil composition and the observation of seismic waves. | Jianhua Lu Songlin Xu Chunhe Miao Yushan Xie Liangzhu Yuan Hao Ma Meiduo Chen Pengfei Wang | 2022 | Deep Underground Science and Engineering2022，1，1： | 1 |

| 16 | Highly selective oxidation of amines to imines by Mn2O3 catalyst under eco-friendly conditions显示文摘Enhancing the selectivity of imines for the oxidative self-coupling of primary amines was found to be challenging in the heterogeneous catalysis.Three different manganese oxides(M-3,M-4,M-5) were synthesized by controlling the calcination temperature using a simple template-free oxalate route.The prepared manganese oxides were systematically characterized using XRD,N2 sorption,SEM,TEM,XPS,H2-TPR techniques.M-4 gave 96.2% selectivity of imine at 100% conversion of benzylamine,which was far more superior than other existing protocols.Mn^3+/Mn^4+ ratio was found to affect the selectivity of the imines.The probable reaction pathway for amines oxidation catalyzed by manganese oxides was proposed for the first time. | Fushan Chen Tao Yang Songlin Zhao Taotao Jiang Lu Yu Houfeng Xiong Chuankun Guo Yufang Rao Yan Liu Liu Liu Jian Zhou Pengxiang Tu Jun Ni Qunfeng Zhang Xiaonian Li | 2019 | Chinese Chemical Letters2019，30，12： | 1 |
| 17 | Cadmium induced a non-coding RNA microRNA535 mediates Cd accumulation in rice显示文摘Identifying key regulators related to cadmium(Cd)tolerance and accumulation is the main factor for genetic engineering to improve plants for bioremediation and ensure crop food safety.MicroRNAs(miRNAs),as fine-tuning regulators of genes,participate in various abiotic stress processes.MiR535 is an ancient conserved non-coding small RNA in land plants,positively responding to Cd stress.We investigated the effects of knocking out(mir535)and overexpressing miR535(mir535 and OE535)under Cd stress in rice plants in this study.The mir535 plants showed better Cd tolerance than wild type(WT),whereas the OE535 showed the opposite effect.Cd accumulated approximately 71.9%and 127%in the roots of mir535 and OE535 plants,respectively,compared to WT,after exposure to 2μmol/L Cd.In brown rice,the total Cd accumulation of OE535 and mir535 was about 78%greater and 35%lower than WT.When growing in 2 mg/kg Cd of soil,the Cd concentration was significantly lower in mir535 and higher in OE535 than in the WT;afterward,we further revealed the most possible target gene SQUAMOSA promoter binding-like transcription factor 7(SPL7)and it negatively regulates Nramp5 expression,which in turn regulates Cd metabolism.Therefore,the CRISPR/Cas9 technology may be a valuable strategy for creating new rice varieties to ensure food safety. | Erkui Yue Fuxi Rong Zhen Liu Songlin Ruan Tao Lu Haifeng Qian | 2023 | Journal of Environmental Sciences2023，，8： | 1 |
