地基分析与设计------外文翻译

We are concerned with placing the foundation on either soil or rock. This material may be under water as for certain bridge and marine structures, but more commonly we will place the foundation on soil or rock near the ground surface. Soil, being a mass of irregular-shaped particles of var..
弹性位移要求：系统参数的不确定性与地型数据的随机性-----外文翻译

摘要：本文的主要内容是：量化成比例的源于(1)广泛承认记录的变化性，(2)内在随机性的系统参数，弹性的总位移比率模式主导结构相当名义上决定横向强度。随机系统参数处理均为：系统正常独立考虑横向屈服强度和系统粘性阻尼比。 Monte Carlo模拟技术是一套选自从20规模地震数据中总结出来被广泛用来取代SDOF系统的数据模..
道路设计-----外文翻译

History of Road DesignFirstly let me apologise for this page. It is largely text based due to the nature of it and if reading is difficult then I am sorry. This is due solely to the material covered and is the only page in the series. This is not typical as the rest have graphics or images to kee..

带有半刚性柱基础的非线性半刚性钢框架的设计-----外文翻译

摘要这篇文章主要讲了带有半刚性连接和半刚性柱基础的钢框架的分析和设计方法。主要分析了梁柱连接的非线性性能和梁柱构件的P -⊿作用。Frye和Morris多项式模型是用来模拟半刚性连接的。构件是根据美国研究所的钢结构建筑（AISC）容许应力设计（ ASD ）的设计规范来设计的。设计过程是互动式的，并给了设计师选择的机会�..
抽水系统PLC和变频调速------外文翻译

改造中应注意的一些技术问题　　　（1）高压变频调速凝结水泵运行时上水调整门打开，利用改变凝结水泵的转速调节除氧器水位造成凝结水压力较低，最大不超过2.8MPa。运行中凝结水压力随负荷降低而下降，为了保证其它设备所需凝结水的压力，所以凝结水母管压力低联锁值应重新整定，但不能太低。例如设定变频调速系统的最低..

大学生在Facebook上的网络社交研究1. Introduction 引言Media use provides an important backdrop for the social, emotional, and cognitive development of youth, accounting for a large portion of their time (Roberts, Foehr, & Rideout, 2005). One type of online application that has grown rapidly in pr..
创意产业穿过文化边缘：电子游戏在亚洲------外文翻译

摘要：这章介绍创意产业中文化、经济与政策之间的关系（就本文的目的，假设等同于文化产业），以及他们在亚洲的表现。寻址这三个问题中的任何一个本身就是一个挑战，但三个问题一起处理更是复杂。之前的“创意经济”学者就发现它的工作不同于传统经济。研究文化是了解创意产业发展相当重要的途径，但是文化如何形成国家..
城市与自然的诗学：走向城市设计新美学------外文资料翻译

The city has been compared to a poem, a sculpture, a machine. But the city is more than a text,and more than an artistic or technological. It is a place where natural forces pulse and millions of people live—thinking,feeling,dreaming,doing. An aesthetic of urban design must therefore be rooted i..
