    当前,中国经济形势缓中趋稳,但下行压力仍然不小,要推动经济社会又好又快发展,高效的政府服务在其中扮演重要的角色。如何通过培训提升公务员的能力素质,达到符合经济社会发展要求、胜任服务性政府工作岗位的需要,已经成为当前关注的热点和焦点。为全面加强公务员队伍建设,《中华人民共和国公务员法》等一系列规范性文件的相继出台,使我国的公务员培训工作日益规范化、制度化。但是,我国公务员培训工作还存在方式单一、针对性不强、“训用分离”、实效性较弱等问题。如果按照传统的培训设计模式,固有的培训“顽疾”难以得到解决,这就需要采用新的思路来思考公务员培训工作,基于胜任力的培训模式的建立可能成为突破瓶颈的一个渠道。 ...The decreasing Chinese economy in recent years highlights the increasing importance of the high-efficiency service provided by civil servants. Improving the ability of civil servants to meet the requirements of economic,social development and governmental service has become a social hotspot nowadays.

    脉冲涡流检测技术是近年来发展迅速的一种新型涡流检测技术。由于其激励信号频谱宽广,不同频率分量的涡流能够渗透到不同深度,使其检测信号包含更丰富的深度方向的缺陷信息,在航空维修等工业领域有着重要的意义。对脉冲涡流检测的仿真可以指导脉冲涡流检测技术的研究。本文利用二维轴对称模型,介绍了脉冲涡流有限元仿真的两种方法—傅里叶变换法和时间步进法,并详细比较了这两种方法的优缺点。Pulsed eddy current testing(PECT) is one of the new techniques of eddy current testing.Thanks to the large amount of frequency components,the response signal contains rich information about defect and material properties along the depth direction.Therefore the PECT plays a significant role in the maintenance of aircrafts,nuclear power plants and so on.This paper introduces the two main methods used in the finite element modeling of PECT.Comparison of the methods is given.航空科学基金项目资助(批准号:2009ZD68004

    Element-free Galerkin method for static and quasi-static electromagnetic field computation

    Get PDF
    Conventional finite-element methods (FEMs) rely on an underlying tessellation to describe the geometry and the basis functions that are used to represent the unknown quantity. Alternatively, however, it is possible to represent both the geometry and basis as a set of points. This alternative scheme has been used extensively in solid mechanics to compute stress and strain distributions. This paper presents an adaptation of the scheme to the analysis of electromagnetic problems in both the static and quasistatic regimes. It validates the proposed model against both analytical solutions and benchmarked FEMs. The paper demonstrates the efficacy of the proposed method by applying it to a range of problems
