| 1 | Numerical Simulation of Temperature Distribution and ThermalStress Field in a Turbine Blade with Multilayer-Structure TBCs by a Fluid–Solid Coupling Method显示文摘To study the temperature distribution and thermal-stress?eld in different service stages,a twodimensional model of a turbine blade with thermal barrier coatings is developed,in which the conjugate heat transfer analysis and the decoupled thermal-stress calculation method are adopted.Based on the simulation results,it is found that a non-uniform distribution of temperature appears in different positions of the blade surface,which has directly impacted on stress?eld.The maximum temperature with a value of 1030°C occurs at the leading edge.During the steady stage,the maximum stress of thermally grown oxide(TGO)appears in the middle of the suction side,reaching 3.75 GPa.At the end stage of cooling,the maximum compressive stress of TGO with a value of -3.5 GPa occurs at the leading edge.Thus,it can be predicted that during the steady stage the dangerous regions may locate at the suction side,while the leading edge may be more prone to failure on cooling. | W.Z.Tang L.Yang W.Zhu Y.C.Zhou J.W.Guo C.LU | 2016 | Journal of Materials Science & Technology2016，32，5： | 15 |
| 2 | ELECTROCHEMICAL INVESTIGATION ON CARBON NANOTUBE FILM WITH DIFFERENT PRETREATMENTS显示文摘Wide potential windows were found at carbon nanotube film electrodes in neutral solutions after being treated with nitric acid and mixed acid. Electrochemical reversibility was investigated at carbon nanotube films with different pretreatments for ferri/ferrocyanide and quinone /hydroquinone. Carbon nanotube film electrodes presented quasi-reversible electrochemical behavior for both electrolytes. In the range of scan rate, carbon nanotube film electrodes treated with acids showed heterogeneous electron-transfer properties, which was mainly controlled by its electron state density on the surface of the film. On the whole, the carbon nanotube electrode with nitric acid treatment presented the best electrochemical behaviors, so we chose it as an analytical electrode to determine the trace compound in dilute solution. The results demonstrated that this new electrode material exhibits superior performance characteristics for the detection of azide anion. | C.G.Hu W.L.Wang W.Zhu | 2003 | Acta Metallurgica Sinica(English Letters)2003，16，4： | 7 |
| 3 | ELECTROANALYTICAL APPLICATIONS OF CARBOXYL-MODIFIED CARBON NANOTUBE FILM ELECTRODES显示文摘The electrochemical behavior of a carboxyl-modified carbon nanotube films was investigated to explore its possibility in electroanalytical applicaton. Cyclic voltammetry of quinone was conducted in 1mol/L Na2SO4, which showed a stable, quasi-reversible voltammetric response for quinone / hydroquinone, and the anodic and the cathodic peak potentials were 0.657V and -0.029V (vs. SCE) at a scan rate of 0.1V.s-1, respectively. Both anodic and cathodic peak currents depended linearly on the square root of the scan rate over the range of 0.01-0. 5 V.s-1, which suggested that the process of the electrode reactions was diffusion-controlled. Carboxyl-modified carbon nanotube electrodes made it possible to determine low level of dopamine selectively in the presence of a large excess of ascorbic acid in acidic media using derivative voltammetry.The results obtained were discussed in details. This work demonstrates the potential of carboxyl-modified carbon nanotube electrodes for electroanalytical applications. | C.G.Hu W.L.Wang K.J.Liao W.Zhu | 2003 | Acta Metallurgica Sinica(English Letters)2003，16，4： | 2 |
| 4 | Soil resource availability impacts microbial response to organic carbon and inorganic nitrogen inputs显示文摘Impacts of newly added organic carbon(C) and inorganic nitrogen(N) on the microbial utilization of soil organic matter are important in determining the future C balance of terrestrial ecosystems. We examined microbial responses to cellulose and ammonium nitrate additions in three soils with very different C and N availability. These soils included an organic soil(14.2% total organic C, with extremely high extractable N and low labile C), a forest soil(4.7% total organic C, with high labile C and extremely low extractable N), and a grassland soil(1.6% total organic C, with low extractable N and labile C). While cellulose addition alone significantly enhanced microbial respiration and biomass C and N in the organic and grassland soils, it accelerated only the microbial respiration in the highly-N limited forest soil. These results indicated that when N was not limited, C addition enhanced soil respiration by stimulating both microbial growth and their metabolic activity. New C inputs lead to elevated C release in all three soils, and the magnitude of the enhancement was higher in the organic and grassland soils than the forest soil. The addition of cellulose plus N to the forest and grassland soils initially increased the microbial biomass and respiration rates, but decreased the rates as time progressed. Compared to cellulose addition alone, cellulose plus N additions increased the total C-released in the grassland soil, but not in the forest soil. The enhancement of total C-released induced by C and N addition was less than 50% of the added-C in the forest soil after 96 d of incubation, in contrast to 87.5% and 89.0% in the organic and grassland soils. These results indicate that indigenous soil C and N availability substantially impacts the allocation of organic C for microbial biomass growth and/or respiration, potentially regulating the turnover rates of the new organic C inputs. | ZHANG Wei-jian W.ZHU S.HU | 2005 | Journal of Environmental Sciences2005，17，5： | 2 |

| 9 | 编码激励信号在岩石超声波速度检测中的应用显示文摘岩石超声波速度的准确检测需要观测波形具有较高的信噪比(SNR)。编码激励技术(CET)能够在不损失分辨率的情况下提高SNR。本研究介绍了相位编码激励原理,并对巴克(Barker)码和戈莱(Golay)码进行了数值模拟与实验评估。实验结果表明,CET虽然能提高信噪比,但信噪比增益(GSNR)低于理论值。红砂岩和花岗岩的超声波速度检测实验证明,巴克码比戈莱码激励信号具有更好的脉冲压缩性能。另外,巴克编码信号在岩石单轴加载时监测速度的应用证实巴克码激励技术是可靠的。 | H.Z.Wu W.Zhu T.M.He Z.Y.Liu X.W.Lan 兰晓雯(译) 朱维(译) 吴何珍(校) | 2020 | 世界地震译丛2020，51，5： | 1 |

| 11 | Do specific ultrasonography features identified at the time of early pregnancy loss predict fetal chromosomal abnormality? e A systematic review and meta-analysis显示文摘To investigate the association of specific ultrasonography features identified during the diagnosis of early pregnancy loss(EPL)and abnormal karyotype.This was a systematic review and meta-analysis conducted in accordance with PRISMA criteria.We searched PubMed,Cochrane and Ovid MEDLINE from 1977 to Jan 2017 to identify the articles that described EPL with karyotype and ultrasonography features.Risk differences were pooled to estimate the chromosomal abnormality rates in ultrasonography features,including pre-embryonic,enlarged yolk sac(YS),short crown rump length(CRL),small gestational sac(GS),symmetrical arrested growth embryo,or gestational sac with only a YS.Quality assessment of included studies was performed using Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklists for Observational Studies(2007 version).Thirteen studies were included in the meta-analysis.Chromosomal abnormality was more likely to occur in embryonic EPL and enlarged YS.On the other hand,short CRL,small GS,symmetrical arrested growth embryo,or gestational sac with only a YS,were not associated with an increased risk of fetal chromosomal abnormality.Ultrasonography features at the time of diagnosis of EPL have limited predictive value of fetal chromosomal abnormality. | J.Huang W.Zhu J.Tang S.H.Saravelos L.C.Y.Poon T.C.Li | 2019 | Genes & Diseases2019，6，2： | 0 |
| 12 | SYNTHESIS OF CoFe_(2)O_(4)/Pb(Zr_(0.53)Ti_(0.47))O_(3)MULTIFERROIC COMPOSITE THICK FILMS BY LOW-SINTERING-TEMPERATURE SCREEN PRINTING METHOD显示文摘CoFe_(2)O_(4)/Pb(Zr_(0.53)Ti_(0.47))TO_(3)(abbreviated as CFO/PZT)multiferroic composite thick films were successfully fabricated on alumina substrate with gold bottom electrode by screen printing method at a low-sintering temperature.The processing included the modi fication and dispersion of ferromagnetic CFO powder and ferroelectric PZT powder,the preparation of uniform pastes,and the selection of proper annealing temperature for composite thick films.Transmission electron microscopic pictures(TEM)indicated the submicron meter of particles size for both CFO and PZT particles.After annealing at 900℃ for 1 h in air,tape test con firmed the quality of multiferroic thick films as well as pure CFO and PZT films.X-ray diffraction(XRD)showed a coexistence of CFO and PZT phases;furthermore,a smooth surface was observed through scanning electron microscopic(SEM)pictures along with the sharp cross-sectional picture,indicative of 100m of film thickness.Ferromagnetic and ferroelectric properties were observed in CFO/PZT films simultaneously at room temperature.Compared with the reported CFO/PZT multiferrroic thin films,the present ferromagnetic property was closing to that of the chemical solgel synthesized film and even that from the physical pulsed laser deposition technique.However,the ferroelectric property showed a degenerated behavior,possible reasons for this was discussed and further optimization was also proposed for the potential multifunctional application. | W.CHEN C.X.HUANG T.S.YAN W.ZHU Z.P.LI X.F.CHEN O.K.TAN | 2011 | Journal of Advanced Dielectrics2011，1，1： | 0 |
