Connectors with assessed quality , for use in d . c . , low - frequency analogue and in digital high speed data applications - printed board connectors - detail specification for 9 mm circular connector with 3 to 8 contacts for use in a wide range of applications including the telecommunication and audio industry 直流低频模拟及高速数字数据系统用经过质量评定的连接器.印制电路板连接器.包括电信和声讯工程等各种用途的带3至8个触点的9mm圆形连接器的详细规范
Honeycomb ceramic has high surface and lighter weight . it is good at the heat insulation , so it is suitable for various kinds of catalyst carriers . it is widely used for automotive emissions control , stationary emissions control , chemical processing and refining industries 蜂窝陶瓷材料具有比表面积大、隔热性较好及重量较轻的特点，因此它适用于各种用途的催化剂载体，现已被广泛应用于汽车尾气净化、固定气体排放的净化、化学工艺、精练工业等方面。
Public open spaces : to avoid massive sun - blasted squares , the open spaces have been distributed into smaller and more distinct spaces surrounded by a diverse mix of facilities which will create multiple experiences to cater to a greater range of tastes and desires of residents and tourists 公众空间：为避免?民及游人于全无遮挡的广阔户外空间中活动，建议把土地分拆成较细小及具独特用途的空间，并加入各种不同的设施，为?民及游人创造一个适合各种用途的活动空间。
In addition , by changing the coloring and supplying additives according to the application , it is possible to produce spheres from materials with characteristics such as specific gravity , thermal resistance , temperature resistance , abrasion resistance or chemical resistance that precisely match the demands of almost any desired application purpose 根据用途加入添加物或染色，就能制作出不同比重，耐热，耐磨损性，耐药蚀性等适应各种用途的材质。有了这些特征，就可以利用在特殊电子管，医疗配件，化妆用品，电脑配件，低比重轴承等众多领域了。
For the parallel analysis , several interfaces have been developed , on one hand , in order to parallelize the existing serial fea codes and make the system practical , some parallel solver library has been integrated into ooparafea ; on the other hand , ooparafea can also integrate self - developed module into its analysis kernel , in fact , it has already integrated parallel cg solver and parallel pcg solver up to now . in webfea , just like other parts in netfeaf , the class hierarchy ( including two dimension fea class library , three dimension fea class library , internet based fem computer aided instruction and so on ) is introduced first , and the control center which integrated httpserver ( used for building internet project web site ) and computingserver ( dealing with different computing tasks ) takes charge of the whole system . netgrawcad is the application of netfeaf in civil engineering , which offers civil engineers a network based works 论文还开发了全新用途的网络服务中心，包括http服务器、计算服务器，以及各种用途的计算客户端：利用java语言的网络通信、界面处理能力结合集群的密集并行计算能力一起完成特定的计算任务，从而使集群计算与web计算很好的集成在一起； webfea作为一种应用客户端，配合netfeaf集成系统的各个计算组成部分，可以实现一个比较全面的有限元分析方法的计算机辅助课件；当前基于web的各种应用越来越广泛，但将基于网络的工程设计与有限元分析系统的面向对象构建其引入有限元分析以及土木工程设计领域还不多，基于netfeaf系统，作者又利用面向对象的方法实现了基于网络的重力式码头cad集成系统，以从根本上改变传统的工程分析设计软件的运行思路，使网络变成土木工程师的日常工作中心，系统部分成果通过鉴定(文通部鉴定为“国内领先，可以大大提高设计效率，建议在水运行业内尽快推广使用” )推出后的良好试用效果，使面向对象的方法在土木工程分析设计软件系统研制中的优势得到进一步验证。
