大学英语精读第三版(上海外语教育出版社董亚芬主编) 第三册Book3 Unit1~Unit10 翻译答案 ? Unit1 翻译 1) 发言人（spokesman）明确表示总统在任何情况下都不会取消（cancel）这次旅行。 The spokesman made it clear that the President would not cancel the trip under any circumstances. 2) 杰克对书架上那些书一本也不了解，所以他的选择是很随意的。 Jack didn't know anything about any of the books on the bookshelf, so his choice was quite arbitrary. 3) 随后发生的那些事件再次证明了我的猜疑（suspicions）是对的。(confirm) The subsequent events confirmed my suspicions once again. 4) 我认为我们应该鼓励中学生在暑假找临时工作。 I think we should encourage high school students to find temporary jobs / employment during their summer holidays. 5) 令我们吃惊的是，这位常被赞为十分正直的州长（governor）竟然是个贪官（corrupt official）。 To our surprise, the governor who had often been praised for his honesty turned out to be a corrupt official. 6) 少数工人得到提升（be promoted），与此同时却有数百名工人被解雇。 A few workers were promoted, but meanwhile hundreds of workers were dismissed. 7) 如果有机会，约翰也许已成为一位杰出的画家了。(given) Given the chance, John might have become an outstanding painter. 8) 数小时后，有人看见那个男孩在林子里瞎转。 Several hours later, the boy was found wandering around in the woods. ? Unit2 翻译 迅速方便地获得信息是很重要，但学会以新的方式看信息甚至更为重要。医学上一次重大突破也许能说明这一观点。科学家本想寻找一种治天花的特效药，但他们没有成功。英国医生爱德华·詹纳放弃寻找特效药，而是通过找到一种预防天花的办法征服了这一疾病。显然，是创造性思维使他的工作获得巨大收获。总之，记住下面这句话肯定大有裨益：有多种方法可以用来看待你下载的大量资料。 It is important to have easy and quick access to information, but it is even more important to learn to look at / view information in new ways. A major medical breakthrough may illustrate the point. Scientists had intended to find a cure for smallpox, but they got nowhere. Edward Jenner, a British physician, abandoned the quest for a cure and conquered the disease by finding a way to prevent it. Obviously, it was creative thinking that led to his fruitful work. In short, it definitely pays to keep this in mind: there is more than one way to look at / view volumes of data you download. ?

概念题 1.1 结构动力计算与静力计算的主要区别是什么？ 答：主要区别表现在：(1) 在动力分析中要计入惯性力，静力分析中无惯性力；(2) 在动力分析中，结构的内力、位移等是时间的函数，静力分析中则是不随时间变化的量；(3) 动力分析方法常与荷载类型有关，而静力分析方法一般与荷载类型无关。 1.2 什么是动力自由度，确定体系动力自由度的目的是什么？ 答：确定体系在振动过程中任一时刻体系全部质量位置或变形形态所需要的独立参数的个数，称为体系的动力自由度（质点处的基本位移未知量）。 确定动力自由度的目的是：(1) 根据自由度的数目确定所需建立的方程个数（运动方程 数=自由度数），自由度不同所用的分析方法也不同；(2) 因为结构的动力响应（动力内力和动位移）与结构的动力特性有密切关系，而动力特性又与质量的可能位置有关。 1.3 结构动力自由度与体系几何分析中的自由度有何区别？ 答：二者的区别是：几何组成分析中的自由度是确定刚体系位置所需独立参数的数目，分析的目的是要确定体系能否发生刚体运动。结构动力分析自由度是确定结构上各质量位置所需的独立参数数目，分析的目的是要确定结构振动形状。 1.4 结构的动力特性一般指什么？ 答：结构的动力特性是指：频率（周期）、振型和阻尼。动力特性是结构固有的，这是因为它们是由体系的基本参数（质量、刚度）所确定的、表征结构动力响应特性的量。动力特性不同，在振动中的响应特点亦不同。 1.5 什么是阻尼、阻尼力，产生阻尼的原因一般有哪些？什么是等效粘滞阻尼？ 答：振动过程的能量耗散称为阻尼。 产生阻尼的原因主要有：材料的内摩擦、构件间接触面的摩擦、介质的阻力等等。当然，也包括结构中安装的各种阻尼器、耗能器。阻尼力是根据所假设的阻尼理论作用于质量上用于代替能量耗散的一种假想力。粘滞阻尼理论假定阻尼力与质量的速度成比例。 粘滞阻尼理论的优点是便于求解，但其缺点是与往往实际不符，为扬长避短，按能量等 效原则将实际的阻尼耗能换算成粘滞阻尼理论的相关参数，这种阻尼假设称为等效粘滞阻尼。 1.6 采用集中质量法、广义位移法（坐标法）和有限元法都可使无限自由度体系简化为有限自由度体系，它们采用的手法有何不同？ 答：集中质量法：将结构的分布质量按一定规则集中到结构的某个或某些位置上，认为其他地方没有质量。质量集中后，结构杆件仍具有可变形性质，称为“无重杆”。 广义坐标法：在数学中常采用级数展开法求解微分方程，在结构动力分析中，也可采用 相同的方法求解，这就是广义坐标法的理论依据。所假设的形状曲线数目代表在这个理想化形式中所考虑的自由度个数。考虑了质点间均匀分布质量的影响（形状函数），一般来说，对于一个给定自由度数目的动力分析，用理想化的形状函数法比用集中质量法更为精确。有限元法：有限元法可以看成是广义坐标法的一种特殊的应用。一般的广义坐标中，广 义坐标是形函数的幅值，有时没有明确的物理意义，并且在广义坐标中，形状函数是针对整个结构定义的。而有限元法则采用具有明确物理意义的参数作为广义坐标，且形函数是定义在分片区域的。在有限元分析中，形函数被称为插值函数。 综上所述，有限元法综合了集中质量法和广义坐标法的特点：(l) 与广义坐标法相似， 有限元法采用了形函数的概念。但不同于广义坐标法在整体结构上插值（即定义形函数），而是采用了分片的插值，因此形函数的表达式（形状）可以相对简单。(2) 与集中质量法相比，有限元法中的广义坐标也采用了真实的物理量，具有直接、直观的优点，这与集中质量法相同。
