Room temperature ferromagnetism of Ni, (Ni, Li), (Ni, N)-doped ZnO thin films

Ni-doped ZnO thin films (Ni concentration up to 10 mol%) were generated on Si (100) substrates by a sol-gel technique. The films showed wurtzite structure and no other phase was found. The chemical state of Ni was found to be bivalent by X-ray photoelectron spectroscopy. The results of magnetic measurements at room temperature indicated that the films were ferromagnetic, and magnetic moment decreased with rise of Ni concentration. The magnetization of Ni (10 mol%)-doped ZnO film annealed in nitrogen was low...     

Experimental study of CT test on the failure of acrylate spray-applied waterproof layer in the groundwater environment

In this study the computerized tomography (CT) was first used to quantitatively analyze the failure of acrylate spray-applied waterproof membrane in the groundwater environment. The results of the CT tests show that it is feasible to use the CT to quantitatively analyze the failure of the waterproof membrane and the CT method has the advantages of speediness and accuracy that can eliminate the fussy operation process in routine tests. The main conclusions summarized from the study are as follows. First, the...     

Simulation of aerodynamic performance affected by vortex generators on blunt trailing-edge airfoils

An investigation was carried out by numerical simulation on a wind turbine airfoil and a blunt trailing-edge airfoil with and without vortex generators (VGs), and the performance of the airfoils was analyzed. By the simulation of airfoil DU 91-W2-250 it was verified that the numerical method and model were credible. Based on this airfoil, a new one with a blunt trailing edge of 6% chord was blended by symmetrically adding thickness, and its characteristics curves were obtained through computing at key angle...     

贯彻工序质量检验标准是产品质量稳定与提升的法宝

Process design for multi-stage stretch forming of aluminium alloy aircraft skin

A process design approach for multi-stage stretch forming was proposed by combining the strain distribution method and finite element method (FEM) to determine the minimum stage number and deformation amount of each stage. The strain distribution method was used to calculate the deformation amount of each stage and evaluate the formability through a safety criterion. FE simulation was taken as an analysis tool to reveal the deformation behaviour, to predict the strain contour and to determine the process parameters at each stage. To evaluate the effect of heat treatment after pre-strain on occurrence of deformation defects during the subsequent deformation, a multi-stage uniaxial tension test for 2B06 aluminium alloy sheet was carried out. A case study demonstrates that the approach has high reliability and good practicability.     

急诊科护理人员工作压力调查分析

目的调查分析急诊科护理人员工作压力现状和相关因素。方法采取方便抽样法对22名急诊科护士进行护士工作压力源量表问卷调查,并对不同编制、学历、职称、班次[A班（08：00-15：00）、P班（15：00-22：00）、N班（22：00-08：00）]的急诊科护士的护士工作压力源量表评分进行比较。结果急诊科护士群体排在前两位的压力因素是病人护理方面的问题、工作量及时间分配的问题。不同编制、学历、职称、班次的急诊科护士的护士工作压力源量表评分比较差异有统计学意义（均P〈0.05）,提示急诊科聘用护士、大学本科及以上学历护士、低职称护士以及值P、N班护士的工作压力程度较重。结论护理管理者应根据护士的不同编制、学历、职称、班次有针对性地给予减压措施,减轻影响护士身心健康因素,以提高临床护理工作质量。
