材料期末考试题目及答案

第一章概述 1、材料与工艺是设计的物质技术条件,是产品设计的前提,它与产品的功能、形态构成了产品设计的三大要素。 2、按材料的物质结构分类,材料可分为: 金属材料:黑色金属(铸铁、碳钢、合金钢)、有色金属(铜、铝及合金等) 无机非金属材料:石材、陶瓷、玻璃、石膏等 有机高分子材料:塑料、橡胶、纤维、木材、皮革等 复合材料:玻璃钢、碳纤维复合材料等 3、材料设计的方式:一、从产品的功能、用途出发;二、从原材料出发。 4、材料的固有特性:物理性能、化学性能。 材料的派生特性:材料的加工特性、材料的感觉特性、环境特性和材料的经济性。 第三章材料感觉特性的运用 1、产品造型设计的三大感觉要素:形态感色彩感材质感 2、材料感觉特性的概念及分类 概念:材料质感又称材料感觉特性,指人的感觉器官(触觉和视觉)对材料作出的综合印象,由人的知觉系统从材料表面特征得出的信息,是人对材料的生理和心理活动。 分类:、一、触觉质感和视觉质感;二、自然质感和人为质感(利用人为质感设计可以做到同材异质感、异材同质感,从而使设计更加灵活多样、变化无穷。) 3、质感设计的三大运用原则:合理、艺术性、创造性地使用材料 4、质感设计在产品造型设计中的作用。 1)、提高适用性—良好的触觉质感设计,可以提高整体设计的适用性。 2)、增加装饰性-——良好的视觉质感设计可以提高工业产品整体设计的装饰性,还能补充形态和色彩所难以替代的形式美。 3)、获得多样性和经济性———良好的人为质感设计可以替代自然质感或弥补自然质感的某些不足,可以节约大量珍贵的自然材料,达到工业产品设计的多样性和经济性。 4)、表现真实性和价值性——良好的整体设计的真实性和价值性。 第五章金属材料及其加工技术 1、金属材料的性能

新概念英语经典题_附答案

新概念英语经典题_附答案 昨日习题: You have so much time. So you ________ worry. A mustn't B needn't C can't 答案:B解析:mustn't 表示绝对禁止needn't表示没必要can't 表示不能。根据句意可知:“你有如此多的时间,所以没必要担心." 所以应该选B. 今日习题:翻译:1. 我今天早上8:00 吃的早饭—————————————— 2. 我已经吃过早饭了。____________________ 今日习题:There _____ a dog and two cats in the gardon . A is B are C am D be 答案:A解析:本题考查There be句型,很多同学会误选B,而There be 句型有一个特殊的规定:“就近原则”,be动词后面是a dog 单数,所以选A is . 昨日习题:用a, an 填空.____ book _________apple _______ hour 答案:a an an 解析:填a 还是an . 是由后面单词的首个因素(音标)决定,而不是首个字母。最容易出错的是hour这个单词。它的音标是['a??],从读音上可判断首个音标是一个元音音标,所以填an . mine .__________________

答案解析:首先特殊疑问句一般是:特殊疑问词+一般疑问句。第一题划线部分做的是The book 的定语,对定语的提问应该用which , 这里是which book. 再加一般疑问句,之前我们第一次练习题里面就有讲到一般疑问句,那四步骤。这里不再说。重点知道一变二(mine变yours).第二题:我的书在桌子上,这里on the desk ,强调位置又做表语. 所以只能用where . 今日习题:(用所给词的适当形式填空)。I _________ (do my homework) now. 答案: am doing my homework解析:有时间是now,可以判断是现在进行时,而现在进行时态的结构是:be+doing ,因为主语是I,所以be 动词只能用am。最后答案是am doing my homework 今日习题:用many /much填空、 I have ______ books. I have _______ money. 答案:many ,much解析:many修饰可数名词,much修饰不可数名词. book是可数的,但是money在英语里面是不可数的。 今日习题:用in front of / in the front of 填空。 The driver is ____________ the bus.(司机在车的内部) There is a tree _______________ the house.(树在房子的外部) 答案:in the front of / in front of 解析:in the front of 是在。。。。内部的前面。in front of 是在。。。。。外部的前面。 今日习题:You get 90 points, I get 60 points . You get ______ mistakes than I get. A. less B fewer C more D many 答案:B解析:Little 比较级是less. few比较级是fewer. little ,less 是修饰不可数名词,few fewer是修饰可数名词。你得了90分,我得了60分。所以你的错误比我的要少,又因为mistakes (错误复数)是可数的,所以选B.今日习题:I ______________ in two weeks .

Unit 5 Topic 1 重点语法一般现在时(常与频度副词never, seldom, sometimes, often, usually, always等连用) 重点句型—How do you usually come to school? —I usually come to school by subway. —How often do you go to the library? —Once/Twice/Three times a week/Very often/Every day/Seldom 重点详解 1. I always come to school by bus. by+交通工具名称,表示使用某种交通方式,中间不加限定词,如果交通工具前有a, the, my 等限定词,就不能用by,而是用in或是on. on the train=by train on his bike=by bike in my car=by car. 巧辩异同on foot 与walk: on foot “走路”,是介词短语,不能作谓语,只作方式状语,位于句末。walk “走路”,是动词,可以作谓语。 go to…on foot= walk to 例:I often go to school on foot. =I often walk to school. 同样,go to….by bike = ride a bike to go to…. by car = drive a car to go to … by plane = fly to go to… by bus = t ake a bus to 2 .Come on! It’s time for class. come on “快点,加油,来吧”。

工程材料期末考试复习题集

第二章晶体结构与结晶 简答题 1、常见的金属晶格类型有哪几种?它们的晶格常数和原子排列有什么特点? 2.为什么单晶体具有各向异性,而多晶体在一般情况下不显示各向异性? 3.在实际金属中存在哪几种晶体缺陷?它们对金属的力学性能有何影响? 4.金属结晶的基本规律是什么?工业生产中采用哪些措施细化晶粒?举例说明。 第三章金属的塑性变形 简答题 7、多晶体的塑性变形与单晶体的塑性变形有何异同? 答:相同——塑性变形方式都以滑移或孪晶进行;都是在切应力作用下产生塑性变形的。 不同点——在外力作用下,各晶粒因位向不同,受到的外力不一致,分切应力相差大,各晶粒不能同时开始变形,接近45℃软位向先滑移,且变形要受到周围临近晶粒制约相互要协调;晶粒之间的晶界也影响晶粒的塑性变形。多晶体的塑性变形逐次逐批发生,由少数开始,最后到全部,从不均匀到均匀。 8.已知金属Pb、Fe、Cu的熔点分别为327℃、1534℃,1083℃、,试估算这些金属的再结晶温度范围?在室温下的变形属于冷加工还是热加工? 9.说明产生下列现象的原因: (1)滑移面和滑移方向是原子排列密度最大的晶面和晶向; (2)晶界处滑移阻力最大; (3)实际测得的晶体滑移所需的临界切应力比理论计算的数值小的多; (4)Zn、α-Fe和Cu的塑性不同。 作业: 1.解释下列名词:滑移、加工硬化 2.塑性变形的实质是什么?它对金属的组织与性能有何影响? 3.何为塑性变形?塑性变形的基本方式有那些? 4.为什么常温下晶粒越细小,不仅强度、硬度越高,而且塑性、韧性也越好? 第四章二元合金 1.解释下列名词:合金、组元、相、相图、组织、固溶体、金属间化合物、晶内偏析。2.指出下列名词的主要区别: (1)置换固溶体与间隙固溶体 (2)间隙相与间隙固溶体 (3)相组成物与组织组成物 答:相组成物:指构成显微组织的基本相,它有确定的成分与结构,但没有形态的概念。例:α和β 组织组成物:指在结晶过程中形成的,有清晰轮廓,在显微镜下能清楚区别开的组成部分。例:α、β、αⅡ、βⅡ、α+β。 (4)共晶反应与共析反应 3.为什么铸造合金常选用有共晶成分或接近共晶成分的合金?用于压力加工的合金选用何种成分的合金为好? 答:铸造性能:取决于结晶的成分间隔与温度间隔,间隔越大,铸造性能越差。 压力加工性能好的合金通常是固溶体,应强度较低,塑性好,变形均匀不易开裂。

建筑材料期末考试题库(简答题)

《建筑材料》期末考试题库 简答题 1.材料的密度、体积密度和堆积密度分别指的是什么? 答: (1)密度是指材料在绝对密实状态下,单位体积的质量。 (2)体积密度是材料在自然状态下,单位体积的质量。 (3)材料的堆积密度是指粉状、颗粒状或纤维状材料在堆积状态下单位体积的质量。 1.什么是材料的弹性? 答:材料的弹性是指材料在外力作用下发生变形,当外力解除后,能完全恢复到变形前形状的性质。这种变形称为弹性变形或可恢复变形。 2.材料与水有关的性质主要有哪些? 答:材料与水有关的性质主要有:材料的亲水性和憎水性以及材料的吸水性、吸湿性、耐水性、抗冻性、抗渗性等。 3.什么是材料的吸水性,影响材料吸水性的主要因素有哪些? 答:材料的吸水性是指材料在水中吸收水分达饱和的能力。 影响材料的吸水性的主要因素有材料本身的化学组成、结构和构造状况,尤其是孔隙状况。一般来说,材料的亲水性越强,孔隙率越大,连通的毛细孔隙越多,其极水率越大。 4.亲水材料与憎水材料各指什么? 答:若润湿角θ≤90°,说明材料与水之间的作用力要大于水分子之间的作用力,故材料可被水浸润,称该种材料是亲水的。反之,当润湿角。>90°,说明材料与水之间的作用力要小于水分子之间的作用力,则材料不可被水浸润,称该种材料是憎水的。 5.影响材料强度测量值的因素有哪些? 答:影响材料强度测量值的因素有:试件的形状和大小;加荷速度;温度;含水状态;表面状况。 6.石灰主要有哪些用途? 答:石灰的用途主要有: ①粉刷墙壁和配制石灰砂浆或水泥混合砂浆。 ②配制灰土和三合土。 ③生产无熟料水泥、硅酸盐制品和碳化石灰板。 7.什么是过火石灰?什么是欠火石灰?它们各有何危害? 答:当人窑石灰石块度较大,锻烧温度较高时,石灰石块的中心部位达到分解温度时,其表面已超过分解温度,得到的石灰称其为过石灰。若缎烧温度较低,大块石灰石的中心部位不能完全分解,此时称其为欠火石灰。 过火石灰熟化十分缓慢,其可能在石灰应用之后熟化,其体积膨胀,造成起鼓开裂,影响工程质量。欠火石灰则降低了石灰的质量,也影响了石灰石的产灰量。 8.什么是石灰的陈伏?陈伏期间石灰浆表面为什么要敷盖一层水? 答:为了消除过火石灰在使用中造成的危害,石灰膏(乳)应在储灰坑中存放半个月以上,然后方可使用。这一过程叫作“陈伏”。 陈伏期间,石灰浆表面应敷盖一层水,以隔绝空气,防止石灰浆表面碳化。 9.什么是石灰的熟化?石灰熟化的特点如何? 答:石灰的熟化是指生石灰(CaO)加水之后水化为熟石灰[Ca(OH)2]的过程。
