基于SDL的通信软件维护模型SMM

软件维护是软件生存周期的一个重要且花费很大的阶段，维护工作的自动化是软件行业十分迫切的需要。本文提出了一个基于ＩＴＵ－ＴＳＤＬ语言的通信软件维护模型ＳＭＭ。在此模型中，软件维护被分成三个部分：建立面向维护的数据库，制定维护规范和基于功能转换的自动维护。该模型将有助于软件维护支撑环境的建立     

Implementing software metrics — the critical success factors

This paper reviews the current state of industry with regard to the introduction of software metrics. It discusses the benefits that organizations have derived from metrication, it looks at why organizations have sought to introduce metrics programmes, how they have gone about introducing those programmes and the problems that they have encountered during implementation. The review found that, on the whole, only the sanitized aspects of metrics experiences have actually been published. This seems to be especially the case with respect to practitioner resistance. Very few organizations admit to having encountered resistance during the introduction of a metrics programme. The paper also includes the results of a pilot study, conducted by the first author, which examines the attitudes that developers hold towards the introduction of software metrics. The key findings of this pilot study are that positive attitudes to metrics correlate highly with levels of education and to job satisfaction.     

新型迷宫式气锚及其应用

新型迷宫式气锚将重力分离原理和离心分离原理有机地结合在一起，其基本型气锚主要由上、下两级组成。上级为离心式螺旋气锚，下级为重力分离式和离心分离式综合气锚，可使油气流经同一长度锚筒时，达到双倍的分离效果。可根据油井气量的大小（气液比值）组成任意级数，实现油气的高效分离。还可对低产能井、沉没度易出现负值的油井进行油气分离，维持油井一定时间的生产。现场28口井的应用表明，新型迷宫式气锚油气分离效果理想，能有效地提高泵效，平均泵效由原来的28．9％提高到43．8％。

Practical method for generation expansion planning based on dynamic programming

This paper presents an efficient method which provides the optimal generation mix and the optimal generation construction process. The approximation method in which the dynamic programming technique and gradient method are combined is applied to determine the optimal generation mix with hydropower generation technologies. The successive approximations dynamic programming (SADP) technique, which is very suitable for high-dimensional multistage decision process problems, is used for obtaining the optimal generation construction process. The effectiveness and feasibility of the developed technique are demonstrated on a practical power system model which has five types of generation technologies including a hydropower generation technology.
