文胸结构设计二--基础纸样的形成

文胸基础纸样是文胸结构设计的重要依据。以新原型为基础，对其进行胸省、腰省的变化及放松量的收紧处理，获得了紧身原型，在此基础上进行了文胸基础纸样的制作，同时获得了罩杯基础纸样，为文胸的款式及造型设计变化提供了依据。     

少女文胸穿着情况调查分析

通过对西安市200名13～18岁少女的问卷调查，分析了影响少女文胸设计、穿着舒适性、消费行为的主要因素．通过数理统计分析方法，得出受少女欢迎的文胸款式、颜色、风格、装饰手法及面料；同时，得出肩带滑落、肩带及下缘束带勒紧皮肤、不合体是引起不舒适的主要因素；舒适、合体、做工质量是影响购买决策的主要因素、

基于ADSL的端对端的宽带业务结构——PPP over ATM over ADSL可用来实现高速Intemet接入及视频点播等宽带业务，该业务结构具有可在现有ISP基础上实现简单升级、支持QoS、协议透明性、多种业务等级等特点。     

文胸的钢圈与下扒配合关系

针对目前文胸下扒纸样设计中使用的定寸法存在多次定位,费时费力的问题,借助Lectra三维扫描仪和Matlab软件,采用回归分析法研究文胸钢圈弧线和下扒侧弧线的配合关系.提出了一种可以准确定位辅助点来精确绘制下扒侧弧线的方法,较好地解决了定寸法的缺点.     

Study on Professional Process of Bra Design

The process of bra design in the underwear industry is studied. Several important aspects of the process were identified: sizing, fabric selection, pattern development and grading, the use of CAD system, fitting and wear trials. Although the design process relies heavily on the expertise and experience of designers, the modern technology such as CAD can facilitate and optimize the design process, and the fitting process on life models is essential for the underwear design. The differences between domestic underwear companies and foreign major ones mainly lie at the lack of dress form specially used for underwear design, lack of CAD/CAM or not making full use of them, and most of all, lack of the professional bra designers or even skillful pattern designers. The prospects and future model of bra design process were also elaborated in this paper.     

微腔反射率对有机电致发光器件性能的影响

有机电致发光器件的法布里-珀罗(Fabry-Perot)谐振腔的光学微腔效应,导致在一定波长处的发射峰强度增强、宽度压窄、发光性能得到改善,因而在有机彩色显示中受到人们的重视。设计了具有不同反射率的两种分布布拉格反射镜(DBR:D istributed B ragg Reflectors),用8羟-基喹啉铝(A lq3)作为电子传输/发光层,N,N′-双(1-萘基)-N,N′-二苯基-1,1′-二苯基-4,4′-二胺(NPB)作为空穴传输层,通过DBR与金属电极反射镜构成法布里-珀罗谐振腔制成了微腔有机发光二极管(MOLED:M icrocavity O rgan ic L ight-Em ittingD iode),详细研究了介质镜(DBR)的反射率、金属镜和有机层的厚度对电致发光效率、发光波长以及光谱半高宽的影响。研究发现,高反射率的DBR虽然可以实现窄的光谱发射,但器件的电致发光效率大大降低,而低反射率的DBR有利于实现单模发射,并且具有较高的电致发光效率,经金属镜和有机层厚度优化后的最大电致发光效率达到了8.3 cd/A,是高反射率DBR微腔器件的6.4倍。     

Development of 3D Female Breast Model Library for Bra Design

As the maturity of female costume concept as well as the social consuming activities, a new and higher requirement is imposed on female underwear design. Human body model is the basic of many applications on 3D garment CAD. This paper delivered a novel approach for modeling a human body which could be driven by related body dimensions to form a female breast model library based on the free form deformatioll technologies. The 3D female breast shape reserve has a strong potential of being used for bra design, bra flttins, virtual try-on and exhibition to meet ＂made-tomeasure＂ demand of the booming bra market in the world.     

基于文胸量身定制的人体特征指标的研究

探讨提高文胸的合体性和文胸的量身定制问题．对西安工程科技学院145名年龄在18～30岁之间女大学生随机取样，进行三维测量；对影响胸部结构造型的12个相关部位尺寸数据进行频数分布、聚类和相关分析；得出决定并区分女性胸部的特征指标，即胸围、胸下围、胸围差、胸宽和胸厚等．根据文胸的量身定制系统的生产方式确定相应的关键参数指标．
