基于MSF的风洞试验分布式数据库系统同步设计

某风洞试验基地各试验外场分布在不同的物理区域,受多种条件制约,不宜采用集中式数据库,任务下达与数据上报采用手动分发与汇总,数据的时效性及完整性存在严重问题;分布式数据库可实现各场站的独立运行,但各场站与中心数据库的同步性、完整性、一致性成为最大的难题;文章根据分布式数据库的特点和风洞试验运行需求,提出了基于MSF(microsoft sync framework)框架并利用WCF(windows communication foundation)技术实现了数据自动上传下达并汇总的同步设计方案,解决了中心与下级场站之间的数据管理问题。     

基于层次分析法的风洞试验装备全寿命健康因素量化评价方法研究

针对风洞试验装备健康管理面临的实际问题,基于层次分析法(AHP)确定装备全寿命过程中影响装备健康的因素体系,并计算各类因素所占的权重,建立了量化评价模型和反馈修正方法,并给出了该方法在风洞试验装备健康管理工作中的实际应用流程。     

基于物联网的涉密设备出入管控系统设计

针对涉密设备安全管理与监控的需要,提出一种全面、连续、实时的监控一定区域内涉密设备出入安全管理的解决方案。主要思想是基于物联网技术,采用有源射频识别（RFID）方法设计和开发了一套涉密设备出入管理系统;首先介绍了系统的总体结构和功能,然后详细描述了涉密设备出入管理系统的软硬件设计方法和系统管理流程,最后给出了新增涉密设备、设备正常带出、设备非法带出、设备报废的系统主要流程的测试结果;测试结果表明系统能够实现所设计的各项功能并具有运行稳定、可扩展性强、可维护性好的特点。     

长骨抗压性能

本文旨在对人的湿润的右股骨与右肱骨的试样进行轴向抗压试验,籍此得到股骨的弹性模量E=9.98×109N/m2,肱骨的弹性模量E=11.37×109N/m2.同时,与国内外的有关资料进行了比较以及讨论.本文还指出了骨组织呈现明显的粘弹性性质,滞后(辶回)线示于图3(a)和(b).并对试验过程中的一些力学现象作了解释.     

The compressive properties of long bones

In this study, compressive tests of the bones along the axial direction have been carried out on some wet specimens of the right femur and humerus, from which there have been obtained the elastic modulus of femur E=9.98×10⁹N/mM² and.’that of humerus E=11.37×10⁹N/m² Also comparisons and discussions have been made with reference to the available data reported abroad and at home.As indicated in this paper, bone tissues obviously possess viscoelastic properties. Their hysteresis loops are shown in Fig. 3 far and (b) and some mechanical phenomena observed during the test are illustrated elsewhere.
