| 1 | Structural and thermal sensitivity of Cu-Zr-Ti amorphous alloys to tension显示文摘Structural and thermal sensitivity of Cu(60-x)Zr(30+x) Ti 10 (x=0,5,and 10 at%) amorphous alloys to the application of tension was investigated. The structural sensitivity to tension decreases with increasing Cu content. The crystallization enthalpy increases with increasing excess free volume. The characteristic temperatures of the tensile samples can surpass those of the as-cast ones under a critical heating rate which differs in the Cu content. The increase of the excess free volume significantly influences the glass transition and crystallization procedures. | CAI AnHui XIONG Xiang LIU Yong AN WeiKe ZHOU GuoJun LUO Yun LI TieLin LI XiaoSong | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，8： | 4 |
| 2 | Mechanism,condition and characteristics for the formation of the network structure in Zr-Al-Ni-Cu bulk metallic glasses显示文摘Mechanism,condition and characteristics for the formation of the network structure in a group of Zr-Al-Ni-Cu bulk metallic glasses(BMGs) were investigated.The results show that the constituent segregation and/or the symplastic growth would be the mechanisms for the formation of the cell structure in the present Zr-Al-Ni-Cu BMGs.The cell structure can be easily obtained for the glass forming alloys whose compositions locate nearby the eutectic point.The shorter the distance is from the eutectic point,the larger the cell and the thicker the cell wall of the network structure will be.The present investigation would provide useful information for the development of the BMG with the network structure. | AN WeiKe DING DaWei CAI AnHui ZHOU GuoJun LUO Yun LI JiangHong PENG YongYi | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，6： | 2 |
| 3 | Large-scale experimental investigation of the effects of gas explosions in underdrains显示文摘This study involved the construction and explosion of a large-scale(80-meter-long)underdrain and detailed investigations of the damaging impacts of a gas explosion to provide an experimental foundation for similarity modeling and infrastructural designs.The experiment vividly recreated the scene and explosion damage of the'11.22″explosion accident in Qingdao,China,thus allowing for evaluations of the movements and destruction of the cover plates.The damage mechanism was determined by analyzing the overpressure curves inside and outside the underground canal.It was determined that the cover plates were first lifted by the precursor wave,which induced a maximum overpressure of 0.06 MPa and resulted in explosion venting.The pressure entered the deflagration stage at the end of the explosion.The combustion wave overpressure reached 3.115 MPa close to the initiation point,and had a significant influence on the projectile energy of the cover plates there.Overall,64%of the cover plates were only affected by the precursor wave,while 36%of the cover plates were subjected to both the precursor wave and the combustion wave;these cover plates were severely damaged.The results of this study provide fundamental insights relevant to the prevention and control of underdrain gas explosions. | Longfei Hou Yuanzhi Li Xinming Qian Chi-Min Shu Mengqi Yuan Weike Duanmu | 2021 | Journal of Safety Science and Resilience2021，2，2： | 2 |
| 4 | Preparation and Characterization of Ag_2S/PMMA Nanocomposites by Microemulsion显示文摘Ag_2S nanoparticles in polymethyl methacrylate(PMMA) are prepared in n-heptane/sodium bis(2-ethylhexyl)sulfosuccinate/water microemulsions.The Ag_2S nanoparticles dispersed in the polymer are characterized by FT-IR spectrum,UV-Vis absorption spectroscopy,transmission electron microscopy(TEM),and X-ray powder diffraction(XRD).The FT-IR spectrum shows that the composite has the characteristic bands of nano-Ag_2S and pure PMMA.The TEM photograph of the sample shows that the Ag_2S nanoparticles are elliptical.The phase structure of the composite is characterized by XRD,which reveals that Ag_2S particles are formed.The UV-Vis absorption recorded at various times indicates an initial rapid formation of the nanoparticles and the quantum confinement effect of Ag_2S nanoparticles. | Yuzhen Li Lizhen Gao Wenjun Chen Weike Zhang Lili Gao Yanqing Yang Likun Shang Meilu Wang | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，1： | 1 |

| 17 | Subsurface banding of blended controlled-release urea can optimize rice yields while minimizing yield-scaled greenhouse gas emissions显示文摘Controlled-release urea(CRU)is widely reported to supply crop nitrogen(N)demand with one basal application,thus effectively replacing split applications of urea without diminishing grain yield and N use efficiency(NUE).However,its use for replacement for high-yield split applications of urea(CK)for rice is untested.In addition,the degree to which greenhouse gas(GHG)emissions in rice systems are affected when CRU is substituted for CK remains unclear.During 2017 and 2018,we sampled plant growth and gas emissions in a rice paddy field treated with three CRU types(sulfur-coated urea[SCU],polymer-coated urea[PCU],and bulk blended CRU[BBU])applied via two methods(surface broadcasting on the soil and subsurface banding at 5 cm depth),with CK as a control.The three CRUs led to different soil NH_(4)^(+)-N dynamics,and the N supply pattern under BBU was more beneficial for rice seedling establishment than under SCU and PCU,resulting in grain yield and NUE comparable to those under CK.CRU type showed no significant effect on either CH_(4) emissions or N_(2)O emissions,and broadcast CRUs exhibited significantly higher total GHG emissions than CK.However,banded CRUs significantly reduced the total GHG emissions in comparison with broadcast CRUs,by 9.2%averaged across the two years.Reduced CH_(4) emissions,particularly during the period prior to the middle drainage,contributed largely to the GHG difference.With comparably high grain yield and low total GHG emissions,banded BBU showed a low yield-scaled GHG(GHG emissions divided by grain yield)comparable to that under CK in both years.Overall,our study suggested that N management synchronized with rice demand and contributing to a high NUE tended to minimize yield-scaled GHG.Broadcast CRU can hardly substitute for CK in terms of either grain yield or GHG emissions,but banded BBU is a promising N management strategy for sustaining rice production while minimizing environmental impacts. | Weiwei Li Sajjad Ahmad Dun Liu Shen Gao Yuhui Wang Weike Tao Lin Chen Zhenghui Liu Yu Jiang Ganghua Li Yanfeng Ding | 2023 | The Crop Journal2023，11，3： | 0 |

| 19 | A Fine Synchronization Method for Coherent Fast Frequency Hopping显示文摘Coherent fast frequency hopping(CFFH)is attracting growing attention owing to its good antijamming performance and the coherent combining ability.However,compared with the conventional non-coherent fast frequency hopping,CFFH requires a more precise system synchronization.In this paper,we propose a new fine synchronization algorithm for CFFH.This algorithm consists two stages,namely,open-loop stage and closed-loop stage.In the openloop stage,a grid-based search parameter estimation method is proposed.In the closed-loop stage,we construct a fully coherent phase-locked loop(PLL)and a delay-locked loop(DLL)with decoding feedback structure to perform further fine estimation of the system clock skew and time delay,respectively.Moreover,we analyze the effect of the search parameter settings on the estimation error and derive the root mean squared error(RMSE)of estimates in the steady state of the closed-loop stage.Finally,through simulation,the RMSE performance are compared with the corresponding Cramer-Rao low bound(CRLB)and conventional code loop estimation to show the effectiveness of proposed algorithm. | Xuanhe Yang Weike Zhang Shixun Luo Chang Li Xiaqing Miao Aihua Wang | 2023 | China Communications2023，20，10： | 0 |
| 20 | A neutron diffraction investigation of high valent doped barium ferrite with wideband tunable microwave absorption显示文摘The barium ferrite BaTi_(x)Fe_(12−x)O_(19)(x=0.2,0.4,0.6,0.8)(BFTO-x)ceramics doped by Ti4+were synthesized by a modified sol–gel method.The crystal structure and magnetic structure of the samples were determined by neutron diffraction,and confirm that the BFTO-x ceramics were high quality single phase with sheet microstructure.With x increasing from 0.2 to 0.8,the saturation magnetization(M_(s))decreases gradually but the change trend of coercivity(H_(c))is complex under the synergy of the changed grain size and the magnetic crystal anisotropy field.Relying on the high valence of Ti^(4+),double resonance peaks are obtained in the curves of the imaginary part of magnetic conductivity(μ′′)and the resonance peaks could move toward the low frequency with the increase of x,which facilitate the samples perform an excellent wideband modulation microwave absorption property.In the x=0.2 sample,the maximum reflection loss(RL)can reach−44.9 dB at the thickness of only 1.8 mm,and the bandwidth could reach 5.28 GHz at 2 mm when RL is less than−10 dB.All the BFTO-x ceramics show excellent frequency modulation ability varying from 18(x=0.8)to 4 GHz(x=0.4),which covers 81%of the investigated frequency in microwave absorption field.This work not only implements the tunable of electromagnetic parameters but also broadens the application of high-performance microwave absorption devices. | Jun LI Yang HONG San HE Weike LI Han BAI Yuanhua XIA Guangai SUN Zhongxiang ZHOU | 2022 | Journal of Advanced Ceramics2022，11，2： | 0 |
