AbstractGoaf, one of potential geological disasters produced by human activities, seriously threats to the coal mine safety production, engineering construction and the lives and property of the people.To treat goaf, the key is to make clear the location, buried depth and present situation of mined-out area.Only we fully understand the spatial distribution of old coal mining area, governance has a definite object.Conventional seismic refection method detecting goaf is based on continuous, homogeneous and smooth reflection interface.The size and the scope of goaf can't be directly described in mined-out area that the reflection interface is damaged affected by mining activities.Applied seismic data to inverse the material property of underground structure, tomography technology has significant advantages in determining internal fine structure and local inhomogeneity of formation.The application of tomography technology is mainly studied in detecting coal mining goaf in this paper.We respectively build goaf tomography by surface-to-surface first break time and hole-to-surface first break time through the numerical simulation method which is based shortest path algorithm and Simultaneous Iterative Reconstruction Technique(SIRT).First, the horizontal resolution was analyzed by comparisons of single goaf models with different scale and double goafs model with perse space beneath the smooth surface.And then the borehole-to-surface deep goaf model with complex surface condition was built to discuss effects of tomography imaging.Finally, the paper analyzed several factors which affect results of tomography.It can be concluded that by model data analyzing: surface-to-surface tomography has approving result in shallow goaf detection with little surface relief and hole-to-surface tomography could have satisfied results in deep goaf with complex surface condition.Applied practical seismic data from Shanxi and Xuzhou, we has separately carried on processing of surface-surface tomography and borehole-surface tomography detecting goaf which obtained a good effect and proved the conclusion.Keywords: tomography;coal mining goaf;velocity inversion

要

牵引变电所作为电气化铁道的供电电源，是铁路供电系统的重要组成部分，直接影响铁路行车安全。由于所内集中的电气设备较多，发生雷击时，很容易引起设备故障，进而影响铁道供电的安全性和可靠性。因此，可通过将避雷器安装在理想的位置，以防止雷击对牵引变电所内设备造成损害，保证牵引供电系统的安全可靠性。

本设计采用EMTP(The Electromagnetic Transients Program,电磁暂态分析程序)应用软件，以哈大线牵引变电所为例，建立220kV牵引变电所仿真模型，对其雷电侵入波的特性进行仿真分析，比较雷击点、杆塔冲击接地电阻、避雷器安装位置等不同因素对牵引变电所内电气设备上过电压的影响，并根据分析结果确定避雷器的最佳安装点。

根据基于EMTP的牵引变电所仿真模型，针对不同避雷器设置方案对雷电侵入波防护效果的模拟和分析结果，选择的最佳避雷器安装方案为：在变压器和互感器入口处均设置避雷器。

As the power supply of electrified railway, traction substation is an important part of the railway power supply system, which directly affects the safety of railway traffic.Because of the large amount of centralized equipment in traction substation, it is easy to cause equipment failure by lightning, and then affect the safety and reliability of railway power supply system.Therefore, the a The Electromagnetic Transients Program e equipment in traction substation from lightning strikes and to ensure the safety and reliability of tractive power supply system.This design uses EMTP(The Electromagnetic Transients Program)application software, take the railway traction substation as an example, the establishment of 220kV traction substation simulation model, electromagnetic transient simulation software, to analysis lightning invasion wave of 220 kV traction substation simulation.Effect on the equipment of lightning struck point, the surge ground-resistance and the place arrester ridded are compared, to ensure the right location of arrester.According to the traction substation model, which based on the EMTP, the effect of lightning overvoltage by different installation scheme about arrester is simulated and analysed.According to the simulation results, it is adopted as lightning protection design scheme that arresters should be located near transformer and mutual inductor.

Asia-Pacific Economic Cooperation(APEC), a single official economic forum at first, now has developed into a economic cooperation organization that plays an important role in the world.As the continually expanding of its scale , its original several members now become 21.Its importance for the world has been greatly improved, and its influence for international regional economic cooperation also has rapidly expanded.This paper makes some introduction to APEC, but the emphasis of it is to study APEC’s influence for international trade and the relevant countermeasures analyses.In 2014, APEC is held again in China.China has joined APEC for 25 years, as the opening of APEC meeting, Chinese actual economic change in this 25 years once again becomes the focus of attention for scholars.For this issue, this paper talks about Chinese development process in this 25 years, and the concerned focus and establishment of countermeasures in 2014 APEC meeting, so that the impact that China’s entry into APEC makes for Chinese trade can be grasped as a whole.For the development situation and existing problems of APEC in recent years, this paper offers some relevant suggestions.And according to the meeting content and development situation, this paper also analyzes APEC’s future planning.

医疗改革在社会主义经济体制下的逐步深入，导致持医保卡消费的病人在病人中占的比例越来越高，医保卡收入在医院的总营业收入中占的比重也越来越大，因此，医保卡使用机制成为医疗保险机构管理的重点。与此同时，近年来，数据挖掘技术的蓬勃发展和逐步走向成熟使得数据挖掘技术在不同行业、不同领域得到了广泛的应用与推广，在医疗保险领域中，数据挖掘技术同样有许多国内外相关的研究与应用，根据这些研究结果，本文将提出当前的数据挖掘技术在医保领域中面临的新兴挑战以及如何应对这些问题。医疗保险欺诈问题已经由来己久，不过，国内在医保卡欺诈检测方面的数据挖掘研究却相对较少。对此，本次课题的研究将从一种欺诈手段入手，即：医保持有人购物范围远远超出医保中心的限定，而药店则以医保卡目录中的药品为名，代替未在限定范围之内的其他商品，形成使用者和药店对医保基金的欺诈。欺诈情节中，提取出相应价款目录的药品对应同等价款目录范围外的其他商品商品，从而对药品的历史消费数据进行挖掘，基于Weka软件，提取并分析出现使用量明显超出正常比例的医保目录药品，挖掘潜在的欺诈信息。辅助医保卡系统安全运营和风险防控，对现代医保卡运营体系进行完善。

鉴于医保资金的浪费数额日益上升，为了防止欺诈行为，让有限的医保资金受益更多群众，各地监管部门陆续加大了审核力度。然而，这就使我们不得不采取更为有效的技术手段来解决新问题，利用更加强大的数据分析工具对现有数据进行深度挖掘和分析，提取出有价值的信息，数据挖掘技术应运而生。数据挖掘技术起初应用在涉及海量数据的领域，随后也逐步延伸至医疗卫生行业，本文将摒除以往数据挖掘技术在临床、诊断等方面应用，从经济效益的角度出发对历史数据进行挖掘分析。针对医疗保险中心系统长期积累的海量历史数据，着眼于与我们生活息息相关、也是医疗保险中最难以应对的问题：对医保卡的欺诈检测。选取目前最为显著地欺诈现象，即：非医保卡使用人持大量医保卡购物，而医疗机构未经核对，采用非本人使用的医保卡，使医疗用品严重流失。鉴于套取医保基金的不良盈利手段，本次实验将基于Weka软件在大量历史账单中整合信息，通过数据挖掘技术，提取并分析出某药店账单中明显超过正常使用量的医保人群，将其认定为具有嫌疑的欺诈人群，从而实现对医保卡持有人的监督与控制。
