60mm电热化学炮技术演示器的研制和试验

作为海军舰艇自卫武器研制计划的一部分，６０ｍｍ电热化学炮演示器已研制成功并进行了试验。该计划是要对新６０ｍｍ速射电热化学炮／自动装填机、近距武器炮架系统装置、电脉冲电源和电热化学弹药进行综合试验。近距武器系统炮架装置在电热化学环境中的成功试验证明，电磁干扰不是什么重要问题。该计划成功地表明，电热化学技术已走出实验室阶段，适用于先进武器系统的发展。     

水面舰艇电热化学炮系统装舰设计考虑

水面舰艇是一个应用发展中电热化学炮系统之类电力武器技术的理想平台，电热化学炮系统正在展示着满足水面火力支援、舰自卫以及战区导弹防御方面的任务需求的能力。但是，电热化学炮系统综合到水面舰艇中需求许多船机电技术以及作战系统开发的协调，以便提供了一个具有费用效能的舰系统。     

国际电磁发射技术研究现状

介绍了国际电磁发射技术研究的最新进展，以及未来的发展趋势和应用方向。总结了电磁轨道炮、电热化学炮研究的热点问题和关键技术，对电磁发射技术研究的阶段和状态进行了深入分析。对于国内相关部门和技术人员有较强的参考和借鉴意义。     

先进的火炮发射技术

为对付技术日益发展的巡航反舰导弹和战术弹道导弹，一些防御系统的策划者已经注意到将导弹和先进的火炮成防御系统的优点。美国的一些军火商早在１０多年前就开始探讨用先进的电热化学炮发射灵巧弹丸反导以及改进中，大口径舰炮完成各种使命的潜力，这项工作现已取得进展，演示炮和弹已进行数次试验。这种技术可用作舰载和陆基对空导弹的补充，将在末段对空防御方面产生极大的影响。     

对岸轰击─舰炮重振雄风

大约２０年前，曾经是海军主要武器系统的舰炮似乎要被导弹取而代之。然而，现在强调的近海作战使各国对中口径舰炮的对岸轰击作用重新发生兴趣。但现役舰炮的口径偏小，射程也近。为提高舰炮的效能，要对现役舰炮进行改进并研究新的发射技术。液体发射药火炮、电热化学炮、精确制导炮弹、火箭增程弹等技术都在发展中。随着对海上火力支援呼声的增大，可能会出现一种主要用于对陆上纵深目标攻击的战舰。     

以电容器为电源的舰用电炮系统的动态仿真

将电炮系统，特别是电磁和电热化学技术应用于舰上，就有一个主动力源和动力装置的组成问题，在某些情况下，大小合适的专用电源给电炮系统供电也许是可行的。然而，在许多情况下，由于舰艇的可用空间、重量和造价的限制，必须与舰艇推进装置共用动力源。在这两种情况下，推进装置的动态特性可能对电磁和电热化学炮的性能产生很大影响。本文叙述采用电容器储能和燃气轮机主动力装置的电热化学炮的动态仿真情况。对专用和共用动力源的系统响应进行比较证明，两种型式都是可行的。     

美国新型舰炮的发展

由于舰炮具有射速高、射击精度好、能全天候作战等特点，故一直受到美国海军的重视。海军现在发展的重点是能对岸进行火力支援的中大口径舰炮、末段反导和防空用火炮以及能满足对岸火力支援和反导防空要求的电热化学炮。

对付反舰导弹的速射电热炮

为了对付不断发展的巡航反舰导弹，美国已研制出世界第一门速射电热炮的演示炮及其配用的小口径灵巧弹药。这种炮具有比较常规发射药火炮更高的初速，且易于改进弹道控制，使用指令制导动能直接命中击毁的弹药提高了命中概率。与之相配套的演示用精确跟踪和瞄准用综合有Ku／W双波段雷达也已交付海军，并进行了试验。这一系统将为海军提供一种效能更好的点防武器系统。     

未来的舰载电能武器

若战斗舰艇能提供足够的电力,则利用电能的电炮和定向能武器就会成为现实。在电炮中最先实现的可能是电热化学炮.研究中的定向能武器有大功率微波武器、高能激光武器和带电粒子束武器。这些武器将首先用于舰艇反导作战。

Recent progress on wave induced loading measurements in warships

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.     

开放式数据挖掘系统模型

目前国内已经出现了少量的数据挖掘相关产品。国内数据挖掘软件无论从数量还是质量上比较，都与国外软件存在着较大的差距。随着数据仓库技术的普及，数据挖掘应用的需求越来越强烈，如何缩短这种差距，研发数据挖掘软件产品成为国内业界的一个重要问题。通过引用目前国际通用数据挖掘标准技术来构建开放式的数据挖掘系统模型，该系统模型从可扩展性、可重用性、易用性等方面得到了加强。
