Automating application software generation

Many approaches have been proposed to enhance software productivity and reliability. These approaches typically fall into three categories: the engineering approach, the formal approach and the knowledge-based approach. But the optimal gain in software productivity cannot be obtained if one relies on only one of these approaches. This paper describes the work in knowledge-based software engineering conducted by the authors for the past 10 years. The final goal of the research is to develop a paradigm for software engineering which integrates the three approaches mentioned above. A knowledge-based tool which can support the whole process of software development is provided in this paper.

An experiment for showing some kind of artificial understanding

In this paper we design an experiment which can be depicted as a simple scenario, a very limited 'world'. In this world, there are an actor that can pursue a project and an observer that is keeping its eyes on the actor. We try to show in the experiment that the observer can to some degree understand the actor based on its knowledge and some metaphors, i.e. understand what the actor is doing and why. As the conclusion of this experiment, we try to show some features of 'understanding'. These are (1) that 'understanding' has to be based on some preliminary knowledge; (2) that 'understanding' is a process of incremental learning; (3) that, as for symbolic systems, some metaphors are necessary for mapping real entities into concepts in mind.     

催化裂化汽油脱硫助剂TS-01的工业试验

中国石油化工股份有限公司九江分公司在I套催化裂化装置进行了TS—0l催化裂化汽油脱硫双功能助剂的工业应用。结果表明：TS—0l剂对催化裂化汽油有较好的脱硫效果。当TS—0l剂注入原料中的量为70μg／g时，对催化裂化汽油的硫脱除率约为20％；注入量为120μg／g时，硫脱除率可达到25％-30％。汽油中脱除的硫主要以硫化氢形态转移至于气、液化气中。TS—01剂对产品分布及产品其它质量无明显影响，该剂亦有良好的金属钝化效果。     

泡沫酸化工艺对川中低压裂缝性油藏适应性的认识

针对川中油田经过多年的消耗式开采,各主产油田压力很低,增产改造的难度增大的发展现状,提出应用泡沫酸化工艺技术在川中低压油层增产改造的技术方案,其中分析了泡沫酸的物理特性、其在地层优良的渗流特性(滤失小、酸岩反应速度慢、返排迅速等优点),并进行了泡沫酸液体系的室内配方研究,提出了工艺设施的矿场配套研究内容.得出了泡沫酸化工艺对川中低压裂缝性油藏改造具有很强的适应性,具有推广应用的价值.

流动注射分光光度法测定钴

研究了将ＰＡＮ用于流动注射（ＦＩＡ）分光光度法测定微量钴，在５６０ｎｍ处绘制标准曲线，线性范围为０～４５μｇ／ｍｌ，相关系数０．９９６，方法的相对标准偏差（ＲＳＤ）小于３％，加标回收率为９５％～１０５％，进样频率８０次／ｈ。本法简单快速，用于面粉、分子筛，铝合金测定结果令人满意。     

肝癌碘油栓塞后肝区平片所见碘油沉积量与疗效关系

本文分析了90例肝癌肝动脉灌注化疗碘油栓塞后,肝区平片所见碘油沉积量和疗效的关系。碘油沉积分为多,中,少三组,从ATP下降,肿瘤缩小率及一年生存率三方面比较。结果沉积多的与中等组三项都有显著差别;沉积中等的与少的组差别不明显。说明碘油沉积要达到一定的量后,疗效才会显著提高。同时分析了影响碘油沉积的几个因素。     

核测井仪器中的磁屏蔽研究

核测井仪器受套管剩磁的影响比较严重，常常用在探测器的周围缠绕多层坡莫合金带的方法进行磁屏蔽，由于缠绕的坡莫合金圆筒不能闭合，加上缠绕过程中坡莫合金带的形变造成材料本身磁导率的下降，传统的磁屏蔽方法的效果不好。本文介绍一种简单易行、磁屏蔽效果较好的方法，实验的结果说明用电工纯铁做探测器的外壳可以达到令人满意的效果。
