4 . equally , we can sum up their effective working model and successful experiences by the analysis the development course and some important items designed by the modern landscape associates in china . 5 . last , we can sum up the shortcomings of these items . the cost of item is too high , the material is more expansive and not understood the civil culture deeply 通过对美国当代园林事务所规划并已实施项目的一些不足加以分析，如用材方面过于高档、昂贵、成本过高，与本土区域文化的理解不深及结合不到位等等，以作到以彼之长短补已之短，有利于国内规划院及设计单位加大自身的竞争力，在今后经济全球一体化，市场公平竞争的国际趋势中立于不败之地。
Proceeding from the structural mechanics , this paper used method which is widely used in structure optimization of industry and civil building to the structure optimization of dairy housing . it was the first time to choose the structural parameters of dairy housing according to the feeding technology , discussed the load values and combinations , optimized the structural materials 本文从结构力学的角度出发，把目前广泛用于工业与民用建筑结构优化的方法用于成乳牛舍的结构优化，首次从饲养工艺的角度对牛舍的建筑参数进行了优选，对荷载的取值及组合进行了讨论，对结构用材进行了优选。
Come for years , we innovate indefatigable effort , actively , the vestibular conception plan that is dedicated to changing a tradition and with material , inspect an user to ask to be oneself , foreign design the concept , advanced technology that make brings our user , make the user feels content is worth somewhat truly 多年来，我们不懈努力、积极创新，致力改变传统的门厅构思方案和用材，视用户要求为己任，将国外的设计理念、先进的制作工艺带给我们的用户，使用户真正感到物有所值。
The press is ingenious in design , hign quality in materials , with features as fine workmanship , handsome appearance , compact structure , higher work pressure , lower work noise , and equipped with single skip . controlled temperature , electric autotimer , so that it will be reliable is operation and easy to repair 本机设计精巧，用材讲究、制造精良、造型美观、结构紧凑，传动部分采用大功率双向电磁离合器，可连续工作，也可单独工作，且有压力大、噪音小、单级跳位、温度自控、电子式时间继电器延时，操作安全可靠、维护保养方便等优点。
The earlier sports shoes mainly for track and field sports , enterprises specialized in sports shoes making sprung up postwar . these included adidas and puma of germany , asxis of japan and later toso and nike of america , all of their own brands and unique styles , materials and functions . their features are : 1 早期的运动鞋主要供田径运动使用，二次大战后，各国涌现出了一批专门制作运动鞋的企业，各树品牌，在款式用材和功能上闯出自己的路子，如德国的阿迪达斯adidas彪马puma ，日本的阿西克斯asxis以及稍后崛起的美国突索toso耐克nike公司。
The reasonable model of exploiting and utilizing to the plant resources is put forward , which should be mainly protected . all kinds of communities are analyzed . the aubor ' s average height of karst evergreen - deciduous forest is 6 . 88m . theuper arbor ' s average height is 13 . 07m . the highest one reaches 25m . the community cover ratio is over 90 % , only few gaps existnatural convalescence forest is inferior to karst evergreen - deciduous forest in the restoration degree . there are a few tall arbor in the community . the height of alpine shrubs forest is 1 . 00 to 2 . 00m . there is no dominant species . the average height of karst shrubs forest is 0 . 97m . the rhus chinensi s , desmodium racemosum and golochidion pubrum are the dominant species 以观赏及绿化树种、用材树种和药用植物等归类对洛塔植物资源作出了评价，观赏植物主要有：玉趼、百合、绣球花等；用材树种有大叶榉、香果树、光灰楸等；药用植物有南方红豆杉、杜仲等，并提出了对植物资源以保护为主的合理开发利用模式。分析各类型植物群落的保护年龄，地质与土壤背景以及群落基本结构和特征，喀斯特常绿落叶林乔木层平均高度为6 . 88m ，上层乔木平均高13 . 07m ，最高可达25m ，群落郁蔽度达90以上。
The second stage is to empolder , populize the ecnomical and applicable wood - frame - construction house and to realize the massive - production . nowaday , the research of the wood - frame - construction house in china have to solve these two problems : the first , the problem of conformation and construction . the second , the problem of design that adapt to china 我国目前的轻型木构小住宅的研究，应立足于第一阶段，解决两个问题： (一)轻型木构小住宅的用材、构造做法、施工技术及相关技术问题(二)适合我国国情的设计方法问题。
In terms of the innovative idea of “ fully wrapped joining ” and the status in quo of recent research on the joining techniques of ceramics and metals , an inverse - wedge - shaped ceramic insert was designed with such strong points as saving material , low cost , reliable joint and easy to manufacture , and some experiential data about it were provided accordingly 根据“全包容”的创新思想和陶瓷与金属的连接技术研究现状,详细设计了用材少、成本低、联接可靠、容易制造的倒楔角陶瓷镶块结构,并提供了相应的经验数据。
The effect of detector disturb and the shell of the detector and construction material is not distinct . the low absorb cross section material is used to 235u - fission chamber . the low z material is used in experimental bracket and shielding material and the material is used less 获得了探测器之间扰动、探测器外壳、支架材料对信号中子测量无明显影响的结果；对~ ( 235 ) u裂变电离室，需采用中子吸收截面低的材料，对实验装置的支撑材料和屏蔽材料宜选用低z材料且尽量减少用材。
The wire size is between0 . 1 ? 0 . 35 . those soft wire materials with their wire sizes 0 . 10 are manufactured by special methods , and can have their percentage elongation higher than 15 % . the company is a special manufacturing factory in the market , and the filament is the ideal material for knitting and shielding materials 线径可从0 . 1 ? 0 . 35 ，其中我厂产品0 . 10软态线材以特殊专有方式生产，延伸率可达15 %以上，是市场上专业的生产厂家，是作为编织屏蔽材料的理想用材。
