Model of Information Integrating in CIMS Based on the Object-oriented Method

Information integrating is the most important key to CIMS,which is the base of the function integrating and all others.Because of so many kinds,so complicated structure,so many different sources and uses that the information in CIMS has,it is necessary to build a popular Information Integrating Model. The model of information integrating in the thesis bases on the enterprise model,which is presented by ISO(International Organization for Standardization).According to the object-oriented method,the process of modeling begins with classifying the information,and then describes the definition of the attributes and the structural relation of those objects. By means of the idea of Encapsulation and Inheritance,the destination of information integrating can be arrive and the model of information integrating can be set up. The model which is based on the share information is helpful to finish the function integrating and the whole CIMS' construction. Moreover,the system which is developed following such program can be reused for many times and the developing circle of CIMS can be apparently shortened,too.     

The research in processing fMRI data using temporal-spatial model based on CCA

In the analysis of cognition of human brain,the fMRI is often used.Corelation is a common method in fMRI data detecting,but its ability should be improved.Based on the Canonical Correlation Analysis(CCA),the temporal correlation and spatial correlation are used together to detect the activated area in the fMRI data.By the application of the method in simulation data and fMRI data,it shows that this method is effective in the detecting.     

Application of Attribute Reduct Method in Spatial Load Forecasting

Spatial load forecasting is a process distributing the total forecasted load to all partitioned area, and involving more spatial information and more factor influencing application of the future small area, which need a great deal of memory space and longer operation time. Rough set is new method of data analysis. It need not be provided with any advanced information except data set. But attribute reduct is its main algorithms. Division matrix approach on rough set used to reduce the attribute related to land - use decision in order to remove redundancy attribute and then the rules of small area land - use decision is distilled. The method obtained better effect and enhanced the total load forecasting efficiency.     

神舟3号飞船搭载的树莓试管苗超微结构及其RAPD分析

已有研究表明,植物进入太空后,其生长、发育、细胞组织结构以及基因组均发生不同程度的变化.例如,大豆[1]及三叶草[2]受空间微重力的影响使其生长明显加快,许多植物的形态及细胞学行为也受太空环境影响[3～10];另外,空间微重力可以改变植物基因表达水平[11～14],半胱氨酸等放射性保护剂的应用进一步证实太空射线可损伤植物染色体[15].但目前有关太空习行对植物试管苗亚细胞超微结构及其基因组影响的报道较少.本文对神舟3号飞船搭载并成功回收的树莓试管苗进行了细胞亚显微结构及RAPD分子标记的初步分析.     

粉花石斛组织培养快速繁殖

采用种子培养(胚培养)和茎节培养直接诱导成苗的方式进行了粉花石斛组织培养快速繁育试验.试验结果表明,无论是以种子还是以茎节作为外植体,均能诱导成苗.种子培养的最适培养基为N6 6-BA 5 NAA 0.4;茎节培养的最适培养基为I/2MS 6-BA 0.9 NAA 0.2;适宜的生根培养基分别为:N6 10%香蕉汁、1/2MS.移栽最适基质配方为腐叶土:珍珠岩为1:1.     

供水系统摇蚊污染特征的调查和分析

供水流程中的摇蚊污染影响水厂生产和自来水水质，S市水厂进行的摇蚊污染特征调查结果表明，污染水厂的摇蚊优势种是花翅摇蚊，水厂孳生的摇蚊来源于进厂原水，摇蚊主要孳生分布在水厂沉淀池。水厂沉淀池形成摇蚊污染的主要原因有：原水的悬浮物和丰富的藻类，沉淀池的温度、溶解氧、pH值，摇蚊幼虫对氯离子和混凝剂浓度的较强耐受性。     

检验喷油嘴时清脆响声的产生与雾化的机理研究

对两种不同密封座直径的喷油嘴在手压式喷油器校验器上进行了对比试验，分析了喷油嘴检验时发出清脆响声的机理，以及响声清脆的喷油嘴其雾化看起来也较好的原因；同时在喷油泵工作转速为1000r/min时用内燃机激光全息照相系统测取了两种喷油嘴的喷雾特性，指出依据喷油嘴检验时发出的响声是否清脆及雾化好坏来评判喷油嘴的优劣是不合适的。     

串行口通信管理模件在水利水电监

在水利水电监控系统中，现场级设备常采用串行口与现地控制单元通信，实现数据交换。为了有效管理通信，现地控制单元一般使用有扩展能力的专门系统。串行口通信管理模件就是这样一种有通信管理能力的嵌入式系统。介绍了串行口通信管理模件的功能和特点，详细分析了基于VxWorks嵌入式实时操作系统的串行口通信管理模件的软件设计。
