发热量和互换性是天然气最重要的两项燃烧性质,但我国目前有关天然气的气质标准中均尚未对互换性作出规定。为此,讨论了确定天然气互换性的几种方法,其中包括沃贝指数法、德尔布法、美国天然气协会（Ａ·Ｇ·Ａ）法,以及国内外根据燃烧性质分类天然气的标准化情况,并就我国管输天然气沃贝指数的标准化问题提出了几点看法。     

CAI在学校教育中的应用与思考

计算机辅助教学(CAI)是利用计算机来模拟教师的行为,通过学生与计算机间的交互活动来达到教学目的.在现代教育中,计算机正逐渐成为有效的教学媒体和教育管理工具.它能给我们提供最理想的教学环境,改变传统的教学模式、教学内容、教学手段、教学方法,并对教育思想、教育理论带来新的根本变革.介绍了CAI的理论基础和演变,并针对在目前教育教学中如何应用CAI进行探讨,论述了CAI对现行教学的影响与将来的发展、如何在学校教育中应用CAI以及在应用过程中需解决的问题等.     

Some Kind of Analogtivity: anti-simulation through design

This paper discusses and explores issues surrounding current approaches to the design of technological products and offers two critical design proposals for presentation and debate. Primarily driven by contemporary theoretical writings and thoughts on the subject of ‘technology’ and ‘simulation’, currently being offered by leading thinkers on these subjects and expressed as ‘technological objects’; they are the result of a critical investigation into the emerging design issues surrounding ‘interaction’ and ‘transparency’. By using ‘popular’ language of product design as a vehicle, they exist as ‘cultural offerings’ exploring an alternative future for technological products not necessarily governed by science and economics.     

Towards a narrative theory of virtual reality

Virtual Reality (VR), by its nature and characteristics, is of specific interest to the AI community, particularly in the domains of Storytelling and Intelligent Characters. We argue that VR must be considered a particular narrative medium alongside Theatre, Literature or Cinema. This paper reviews relevant work in narrative theory from Plato onwards, including the work and theories of literary critics [1], cinema critics [2–4] and theatrical dramaturges [5], and analyses the specific characteristics of VR relevant to this theory. Less studied media such as Live Role Playing Games, improvisational drama and participatory drama are also considered. Finally, this document argues for a participatoryprocess-oriented narrative, with particular attention to the specificities and particularities of stories and their possible representation, adapted to the narrative medium Virtual Reality.     

Interactive lectures: Effective teaching and learning in lectures using wireless networks

Among the severe instructional shortcomings of lectures is their lack of interactivity. To overcome these problems, the learning environment of the interactive lecture is introduced, in which students and lecturer interact by using mobile computers in a wireless network. In an experimental study, 44 students participated in interactive and in conventional lecture meetings. A quiz service that allowed question to be posted, students’ answers to be evaluated, and the results to be presented graphically, was implemented on mobile computers. The participants rated the interactive condition better, also reporting higher levels of attention, activity and perceived learning success for this condition. Objective measures indicated a slight but insignificant difference toward better learning results in the interactive condition.

3-氨基喹啉与常用基体在MALDI-TOFMS测定天然提取植物多糖的比较

采用3-氨基喹啉(3-AQ)、二元基体3-AQ/2,5-二羟基苯甲酸(DHB)及常用于糖类物质测定的DHB和二元基体DHB/1-羟基异喹啉(1-HIQ)对一天然提取植物糖样进行了基体辅助激光解吸/电离飞行时间质谱(MALDI-TOF MS)分析。实验结果表明:此植物糖样由线形和环形聚己糖组成,其最大分子量至少达3000 Da;3-AQ与常用基体DHB及DHB/HIQ相比较,能提供更准确、更全面的样品组成及分子结构信息,且具有优越于常用基体解吸电离环状糖分子的能力。     

Kernel for a responsive and graphical user interface

A kernel that facilitates building graphical and responsive user interfaces for application programs has been constructed. A display tree representing the structure of the 2-dimen-sional screen image is defined. Each node contains an input procedure, an output procedure and links to their arguments. This display tree is the only interface between the user and the application program. For viewing purposes, the display tree can be ‘painted’ onto any viewport. The output routines attached to the nodes are invoked to produce the image. The arguments found in the ancestor nodes can be thought of as shared graphical attributes. Upon each input event, the display tree is traversed to determine which node is touched by the cursor. The input procedure attached to that node is then invoked. The use of a library with standard attached procedures (e.g. for screen editing and error checking) leads to a system that behaves uniformly across applications. Some demonstration programs, based on this kernel, show the very dynamic screen communication that can be achieved.
