浅谈Delphi程序文件的组成及应用

Delphi是一门很好的可视化编程工具,为更好的让一些初级入门的开发人员了解这门技术,从最基础的工程文件的组成、窗体单元文件代码内各个部分的组成讲起,最后附带一个总结性实例,让初级开发人员更深入地学习了解Delphi开发工具。

CD—ROM光盘的卷和文件结构(1)

CD—ROM的卷和文件结构标准是1988年制定的,它的标准号为ISO 9660。在ISO 9660中,对CD—ROM的文件结构进行了定义,以便在不同信息处理系统的用户之间交换信息。本文介绍ISO 9660标准的内容。

计算机数据恢复技术探究

计算机以及相关的移动设备,帮助人们存贮大量有价值的数据信息。这符合信息高速发展的趋势。但在使用过程中由于个人使用不当,或者软件与硬件故障的发生,会让这些设备丢失部分储存信息。而这些信息对用户的价值可能巨大。而数据恢复技术可以帮助人们找回这些重要的信息。本文从技术角度出发,分析了数据丢失与损坏的原因。阐述了数据恢复技术的原理,以及一些行之有效的数据恢复方法。

Pioneering Proposal of Floating Type Ocean Wave Power Station

This serial research develops the unique ocean wave power station, which is composed of the floating type platform with a pair of the floats arranged at the interval of one wavelength and the counter-rotating type wave power unit whose runners are submerged in the seawater at the middle position of the platform. Such profiles make the flow velocity through the runners two times faster than that of the traditional fixed/caisson type OWC （oscillating water column）, that is, the runners may be able to get the dynamical energy eight times on the ideal. Besides, the runners counter-drive the inner and the outer armatures of the peculiar generator, respectively, and then the relative rotational speed is two times as fast as the speed of the single runner/armature. Such characteristics make the runner diameter large, namely the output higher, as you request, because the rotational moment of the power unit hardly act on the floating type platform. This paper, as the first step, discusses the platform behaviors at the normally oscillating wave. The platform behavior is affected by not only the length and the amplitude of the wave but also the relation between the weight of the platform and the buoyancy force of the floats.
