面向软件动态演化的需求建模及其模型规范化

针对目前需求工程阶段对软件动态演化考虑不足的现状,在分析软件动态演化面临的挑战的基础上,设计了面向动态演化的需求元模型(dynamic-evolution-orientedrequi rements meta-model,DERM)。该元模型以特征为基本部件,按特征组合的方式建立需求模型,需求模型由行为特征和属性特征组成。行为特征被区分为计算行为特征和交互行为特征,以实现计算和交互的相对隔离;属性特征通过其作用域,指定其在行为特征模型中的作用范围,从而将行为特征模型和属性特征模型统一为需求模型。在此基础上,讨论了需求模型的参照完整性、依赖一致性和互斥一致性,并进一步把需求模型规范化为需求模型第一范式到第三范式,需求模型规范化的过程提供了一种保证需求模型一致性的方法。最后通过案例研究,表明了该方法的可行性及其对软件动态演化的有效支持。

快燃物ACP在丁羟复合固体推进剂中的应用

采用药条燃速仪试验和Ф64mm发动机点火试验,研究了不同含量的快燃物ACP对低、中、高燃速丁羟复合固体推进剂燃烧性能的影响。结果表明,快燃物ACP能明显提高推进剂的燃速,使6．86～15MPa下推进剂的燃速压强指数有明显增大的趋势,在低、中、高燃速推进剂配方中加入质量分数为5％的ACP,15MPa下的燃速分别提高11．3％,82．9％,67．8％。Ф64mm发动机试验表明,含ACP的推进剂在发动机中能够稳定燃烧,发动机p-t工作曲线稳定。获得了ACP使推进剂产生非平行层燃烧从而大幅度提高燃速的初步证据。     

含快燃物ACP丁羟推进剂高压燃烧特性和常压火焰结构

为了研究水合-四-(4-氨基-1,2,4-三唑)高氯酸铜(ACP)对推进剂燃烧特性的影响,利用高压燃速测定系统研究了ACP对丁羟推进剂3～29 MPa压力范围内燃速的影响;收集推进剂在不同压力(3,10,20 MPa)下的燃烧产物,分析了ACP对燃烧产物化学组成的影响;采用显微高速摄像系统获取了推进剂的燃烧火焰和燃烧表面,对燃烧熄火表面及组分进行了研究。结果表明,在丁羟推进剂中添加ACP可大幅提高燃速,添加5%ACP可使推进剂29 MPa下的燃速提高84.8%,9～11 MPa为不稳定燃烧压力区。燃烧压力3 MPa的完全燃烧产物中活性铝含量为16.22%。推进剂在0.1 MPa燃烧时,存在粒径约100μm的粒子被燃烧气流从燃烧表面带入到气相区中分解燃烧的现象,熔铝粒子在燃烧表面无明显团聚。添加ACP使燃烧表面不规则程度增加。     

Enamel alteration following tooth bleaching and remineralization

The purpose of this study was to compare the effects of professional tooth whitening agents containing highly concentrated hydrogen peroxide (with and without laser activation), on the enamel surface; and the potential of four different toothpastes to remineralize any alterations. The study was performed on 50 human molars, divided in two groups: treated with Opalescence^® Boost and Mirawhite^® Laser Bleaching. Furthermore, each group was divided into five subgroups, a control one and 4 subgroups remineralized with: Mirasensitive^® hap+, Mirawhite^® Gelle?, GC Tooth Mousse? and Mirafluor^® C. The samples were analysed by SEM/3D‐SEM‐micrographs, SEM/EDX‐qualitative analysis and SEM/EDX‐semiquantitative analysis. The microphotographs show that both types of bleaching cause alterations: emphasized perikymata, erosions, loss of interprizmatic substance; the laser treatment is more aggressive and loss of integrity of the enamel is determined by shearing off the enamel rods. In all samples undergoing remineralization deposits were observed, those of toothpastes based on calcium phosphate technologies seem to merge with each other and cover almost the entire surface of the enamel. Loss of integrity and minerals were detected only in the line‐scans of the sample remineralized with GC Tooth Mousse?. The semiquantitative EDX analysis of individual elements in the surface layer of the enamel indicates that during tooth‐bleaching with HP statistically significant loss of Na and Mg occurs, whereas the bleaching in combination with a laser leads to statistically significant loss of Ca and P. The results undoubtedly confirm that teeth whitening procedures lead to enamel alterations. In this context, it must be noted that laser bleaching is more aggressive for dental substances. However, these changes are reversible and can be repaired by application of remineralization toothpastes.

Reliability of flip-chip bonded RFID die using anisotropic conductive paste hybrid material

A reliability of flip-chip bonded die as a function of anisotropic conductive paste (ACP) hybrid materials, bonding conditions, and antenna pattern materials was investigated during the assembly of radio frequency identification(RFID) inlay. The optimization condition for flip-chip bonding was determined from the behavior of bonding strength. Under the optimized condition, the shear strength for the antenna printed with paste-type Ag ink was larger than that for Cu antenna. Furthermore, an identification distance was varied from the antenna materials. Comparing with the Ag antenna pattern, the as-bonded die on Cu antenna showed a larger distance of identification. However, the long-term reliability of inlay using the Cu antenna was decreased significantly as a function of aging time at room temperature because of the bended shape of Cu antenna formed during the flip-chip bonding process.
