抽油井示功图神经网络识别模型

以专家经验及大量的现场实例为基础，应用模糊数学与人工神经网络技术理论，建立了有限个精选井下示功图和反向传播的神经网络示功图识别模型．该识别系统可初步用于对现场实测示功图进行识别诊断，性能基本稳定，能有效地诊断抽油机的故障类型．     

人红细胞衰老过程抗氧化酶活性的研究

本文以新鲜及保存不同时间的献血员血液为研究材料,分别测定混匀、年老、年青三种状况 RBC 中的 GSH-PX、CAT 和 SOD 活性,获得了随血液保存期延长而三种酶活性皆显示逐周下降的结果。并且观察到年老 RBC 中三种酶活性比年青 RBC 中的酶活性更低、差别显著。我们的结果提示,RBC 衰老过程与这些抗氧化酶活性下降密切有关。

水稻单细胞培养及植株再生

对以水稻幼穗为外植体诱导的愈伤组织进行振荡培养,分离出单细胞。观察到两种细胞类型:一类细胞呈圆形,其核较大,细胞质较致密,分裂活性较强;另一类细胞呈长形或不规则形,其核较小,细胞质较少,很少见到分裂现象。这两类细胞数目与培养基中大量元素、肌醇和2.4-D浓度有很密切的关系。通过半连续悬浮培养使圆形细胞增加,培养40～60天后圆形细胞数达95%。观察到单细胞活体连续分裂的过程及从悬浮培养细胞液中滤出的单细胞再生成了植株。

Image Post-Processing Method for Visual Data Mining

Visual data mining is one of important approach of data mining techniques. Most of them are based on computer graphic techniques but few of them exploit image-processing techniques. This paper proposes an image processing method, named RNAM （resemble neighborhood averaging method）, to facilitate visual data mining, which is used to post-process the data mining result-image and help users to discover significant features and useful patterns effectively. The experiments show that the method is intuitive, easily-understanding and effectiveness. It provides a new approach for visual data mining.     

浅谈企业改制后职代会与职工持股会的作用

企业改制，是社会主义市场经济体制运行下的必然趋势，是促进社会生产力发展的重要途径。企业改制后，工会要突出维护职工权益的职能，民主管理渠道要更畅通，工作思路需不断创新拓宽。     

Cache-Conscious Index Mechanism for Main-Memory Databases

Recent studies have addressed that the cache be havior is important in the design of main memory index structures. Cache-conscious indices such as the CSB^＋-tree are shown to outperform conventional main memory indices such as the AVL-tree and the T-tree. This paper proposes a cacheconscious version of the T-tree, CST-tree, defined according to the cache-conscious definition. To separate the keys within a node into two parts, the CST-tree can gain higher cache hit ratio.
