舰炮世纪回眸(续)

3　战争需求与舰炮的发展不管是二战以前的大口径舰炮 ,还是战后的中小口径舰炮 ,其发展都离不开战争需求。作为最早使用的基本舰载兵器 ,舰炮从来没有像现在这样面临着导弹等高技术舰载兵器的巨大挑战 ,也从没有像现在这样不断采用高新技术而具有巨大的发展潜力与发展速度。舰炮从不同角度有不同的分类 ,如主炮与副炮之分 ;平射炮与高平两用之分 ;单管、双管、多管联装、转管、转管联装舰炮之分 ;又有大、中、小口径舰炮之分 (在口径分法上各国很不统一 ,而我国根据现代舰炮口径的发展趋势 ,常把 2 0～ 6 0ｍｍ作为小口径、6 0～ 10 0ｍｍ…

舰炮世纪回眸

本文从两个不同的角度和四个方面回眸了舰炮风雨百年的发展历程。舰炮的发展 ,一直都离不开战争的需求 ,特别是经受住了导弹的严重挑战后仍获得迅速发展。这是因为战争需要舰炮 ,而导弹又无法代替舰炮的全部功能。本文前两部分通过典型战例 ,说明在以舰炮为主战兵器的“大舰巨炮”时代对夺取制海权、取得海战胜利的重要作用以及现代海战中舰炮的功能 ;后面两部分则根据未来海战对舰炮的需求 ,从技术角度审视舰炮的发展。随着科学技术的进步和高新技术的应用 ,舰炮技术一定会不断创新 ,舰炮一定会获得新的活力     

浅谈我国大口径舰炮的发展

大口径舰炮通常指100毫米以上口径的舰炮。二战后,由于航空武器的发展和导弹武器的出现,舰炮变成了水面舰艇的辅助武器,大口径舰炮的发展进入了一个低潮,装舰数量大幅度减少。各国主力舰艇通常只装备1～2座。 我国舰炮研制工作起步较晚。上世纪60年代,我国在引进苏联技术的基础上,研制成功第一代双130毫米舰炮。90年代中期。我国引进了“现代”级驱逐舰,其上的新双150毫米舰炮作为附属项目被一并引进。随着我国海军现代化水平的提高,新一代大型驱逐舰呼之欲出,选择什么样的主炮就成为大家关注的话题。本文来盘点一下国产大口径舰炮的发展历程,并对未来我国大口径舰炮发展做些简单推测。[编者按]

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。
