8第十七章 光的衍射作业答案
一、选择题 [ B ]1、(基础训练1)在单缝夫琅禾费衍射实验中,波长为λ的单色光垂直入射在宽度为a =4 λ 的单缝上,对应于衍射角为30°的方向,单缝处波阵面可分成的半波带数目为(A ) 2 个 (B ) 4 个 (C ) 6 个 (D ) 8 个 【答】已知a =4 λ,θ=30°,1sin 4422a λθλ∴=⨯=⨯,半波带数目N = 4. [ C ]2、(基础训练5)一单色平行光束垂直照射在宽度为1.0 mm 的单缝上,在缝后放一焦距为2.0 m的会聚透镜。
已知位于透镜焦平面处的屏幕上的中央明条纹宽度为2.0 mm ,则入射光波长约为(A )100 nm (B )400 nm (C )500 nm (D )600 nm 【答】中央明条纹宽度为2, 5002x ax fnm afλλ∆⋅∆≈∴== [ B ]3、(基础训练6)一束平行单色光垂直入射在光栅上,当光栅常数(a + b )为下列哪种情况时(a代表每条缝的宽度),k =3、6、9 等级次的主极大均不出现?(A )a +b =2 a (B )a +b =3 a (C )a +b =4 a (A )a +b =6 a【答】光栅缺级:()sin sin 'a b k a k θλθλ+=⎧⎨=⎩,缺级的主极大的级次为',2,3,...a b a b a b a bk k a a a a++++==,k 应为整数,依题意,k=3,6,9缺级,所以a+b=3a 符合。
[ D ]4、(基础训练10)孔径相同的微波望远镜和光学望远镜相比较,前者分辨本领较小的原因是 (A ) 星体发出的微波能量比可见光能量小 (B ) 微波更易被大气所吸收 (C ) 大气对微波的折射率较小 (D ) 微波波长比可见光波长大 【答】分辨本领为11.22RdR θλ==,孔径d 相同时,R 与波长λ成反比关系。
微波波长比可见光波长大,所以微波望远镜分辨本领较小。

In the villages of Scotland, barrels of tar (沥青) are set on fire. It represents that the old year is burned up and the new one is allowed to enter.New Year’s Day is also the Festival of Saint Basil in Canada. Children leave their sh oes by the fireside on New Year’s Day with the hope that Saint Basil, who is famous for his kindness, will come and fill their shoes with gifts.The Jewish New Year is called Rosh Hashanah.

第八讲练习题一、概念解释1.道德与品德:道德是由社会舆论和内心驱使来支持的、反映一定群体共同价值的社会行为规范的总和。
品德,即道德品质,也称德性或品性,是个体依据一定的道德行为准则行动时表现出来的稳固的倾向与特征。
2.道德认识:道德认识指对社会道德规范及其执行意义的认识。
3.道德情感:道德情感是人的道德需要是否得到满足而引起的一种内心体验。
4.道德意志:道德意志是个人在道德情境中,自觉地调节行为,克服内外困难,实现道德目的的心理过程。
5.道德行为:道德行为指在道德意向支配下表现出来的符合社会道德规范的行为。
6.品德心理结构:生成结构、执行结构和定型结构。
7.他律道德:道德判断具有强烈的尊重准则的倾向,这些准则都是权威人物制定的,是不可改变的,如同自然法则,这是一种“道德实在论”。
8.自律道德:社会准则是共同约定的,并不是绝对的,这是一种道德相对论。
9.前习俗水平:该水平的道德推理关注行为引起的结果,着眼于行为的具体后果和自身利害关系来判断是非,儿童无内在的道德标准。
判断一种行为是否适当,主要是看其能否使自己免于受罚,或让自己感到满意。
这个水平包含两个阶段:惩罚与服从取向和相对功利取向。
10.习俗水平:不再根据直接的具体结果来看待行为,而能考虑到更多的社会性因素来作出道德问题的决定,该水平的道德推理包括两个阶段:寻求认可取向和遵守法规取向。
11.后习俗水平:此阶段的青少年能够依据自己选定并遵循的伦理原则和价值观进行道德判断,认为不违背多数人的意愿、不损害多数人的幸福、不违背普遍的道德原则的行为就是最好的行为。
处于后习俗水平的青少年,已经超越现实道德规范的约束,达到完全自律的境界。
该水平由两个阶段组成:社会契约取向和普遍伦理取向。
二、单项选择题(在每小题给出的四个选项中,选出一项最符合题目要求的选项)1.道德认识只有转化为(D),才能够真正支配个体的道德行为。
A.道德认识 B.道德情感 C.道德价值 D.道德观念2.(B )是人的道德需要是否得到满足而引起的一种内心体验。
A.道德认识 B.道德情感 C.道德行为 D.道德观念3.根据行为造成的客观损失后果的大小来判断行为错误的严重程度属于(A)的道德判断。

2.品德的心理结构主要包括道德认识、道德情感、道德意志、道德行为。
3.品德形成的一般条件包括一般认知能力、交往需要与合作经验个人原有的信念社会道德环境强化与惩罚等。
4.皮亚杰将儿童的道德认知发展分为自我中心阶段、权威阶段、可逆性阶段和公正阶段四个阶段。
5.科尔伯格将习俗水平的道德判断分为_寻求认可取向_和遵守法规取向两个个阶段。
四、判断正误1.道德是品德的表现形式(×)2.品德是道德认识、道德情感、道德意志、道德行为的组合。
(×)3.道德教育应该依据道德认识、道德情感、道德意志、道德行为顺序而展开。
(×)4.儿童的道德认知发展是从自律走向他律。
(√)5.青少年的知、情、意、行是统一的。
(×)五、简答题1.什么品德?心理结构有哪些方面?答:品德,即道德品质,也称德性或品性,是个体依据一定的道德行为准则行动时表现出来的稳固的倾向与特征品德的心理结构涉及品德所包含的心理成分及其相互联系和制约的模式。
探讨品德的心理结构不但可以深化对品德本质的认识,更能对儿童、青少年的品德培养提供依据。
目前对这一问题的研究有两种思路:一是探讨品德的因素结构,侧重查明品德是由哪几种相互联系的因素或成分构成的;二是探讨品德的功能结构,侧重查明品德的各种成分如何生成以及如何在各种内外条件的作用下完成道德决策和行为的。
2.品德形成的实质、过程与一般条件是什么?答:实质:人类个体品德的形成过程即品德学习的过程,亦即社会规范学习的过程,其实质是个人在社会生活实践过程中,在家庭教育、学校教育以及社会道德舆论的影响下,内化社会道德规范和道德价值,形成个人社会行为的心理调节机制的过程。
过程:品德的形成就是内化社会道德规范、道德价值,确立社会规范的遵从态度的过程。
这一过程是逐步完成的,按内化水平不同,分为三个层次或阶段:对社会规范的依从、对社会规范的认同和对社会规范的信奉。
这些阶段的实现依赖于不同的条件。
一般条件:品德形成的不同阶段有着不同的制约条件,对于品德心理结构的不同成分的形成有着不同的影响因素。
这里我们先讨论影响个人品德发展的一般的条件,包括主观条件和社会环境条件。
内部主观条件有认知能力、交往的需要与合作经验、已有信念等,外部的环境条件有社会环境的影响、社会反馈与强化等。
(1)一般认知能力认知心理学家认为,儿童逻辑推理能力是其道德判断能力发展的基础。
儿童从单方面服从权威的他律道德转向双方互相尊重的自律道德,与其思维去中心化能力的发展有关。
个人道德成熟要依据公正、平等、人的价值等抽象的道德原则,而不是依据具体的道德律令进行道德判断的水平,显然要以其抽象逻辑思维的发展为基础。
(2)交往需要与合作经验交往需要、归属需要是人的基本社会性需要。
个人交往要获得成功,得到他人的认可和团体的接纳,就必须学习和遵循道德规范。
在与成人、同伴合作的过程中,儿童增加了解他人的观点和感受,减少了自我中心倾向,提高了角色采择能力;同时也有机会获得对自己行动的反馈,增强自己对道德准则的意义的理解。
与和成人的交往相比,同伴互动更有可能促进儿童道德发展。
(3)个人原有的信念就像认知领域的学习需要一定的知识基础一样,品德学习也需要已有的信念为基础。
已有信念决定一个人在道德情境中选择什么信息,如何解释道德事件。
已有信念与个人过去生活经历、替代经验、社会评价的一致性等有关。
(4)社会道德环境社会道德环境、社会风气、日常生活中发生的道德事件及舆论对个体的评价,都对个体品德的形成和发展产生直接的影响。
其中榜样人物的行为及后果对儿童青少年的道德发展有着重要影响。
可以作为榜样的人物首先是父母、教师、同伴,此外,社会精英人物、社会公众人物、文艺作品的主人翁、社会传媒所宣传的人物等,他们的言行都会对青少年潜移默化地产生示范作用。
其中有些人及其积极的或消极的行为,并非是有意作为榜样呈现的,但同样可能被观察者当作示范来仿效。
榜样示范作用的大小,一是取决于榜样及其示范行为的特点,如榜样人物的地位、人格吸引力、与观察者主客观条件的相似性,以及示范行为的鲜明性、可行性、可信性等;二是榜样行为的后果,即示范行为是否受到奖励、是否受到集体或全社会的推崇。
(5)强化与惩罚班杜拉谈到社会行为的直接强化、替代强化和自我强化。
无论是亲历学习,还是观察学习,强化与惩罚都会对人的社会规范学习及其行为表现产生影响。
3.如何培养与提高青少年的道德认识?答:为了促进学生道德观念的形成,在德育过程中应注意:将抽象道理与具体事例相结合;在列举道德实例时要运用变式,使学生更好地理解道德观念的实质;通过提供榜样,提高学生的道德判断和推理水平;运用强化手段促进道德认识的发展;运用假想的,或真实的道德两难情境,或组织学生针对社会上发生的道德事件进行讨论和辩论,提高道德推理水平。
当社会道德规范内化为个人行动的指南时,就成为个人的道德信念。
道德信念的确立是道德品质形成的心理实质。
道德信念的特点是其原则性、动力性、坚定性和情绪色彩。
有了道德信念的人,对道德规范及其意义具有概括的认识,赋予社会道德规范以价值,坚信其正确性,并愿意在行动上加以贯彻,甚至当社会反馈 (奖励与惩罚力与其道德信念不一致时,仍能按照道德信念行事。
道德认识转化成道德信念有赖于多种条件。
第一,教育者的言行一致。
教育者的行为就是其向学生讲解道德规范的意义的最好例证。
教育者言行一致,使学生认识到,按照道德规范去行动是值得的,是正当的;反之,教育者言行不一致,就会使学生对道德规范产生质疑。
第二,在道德实践中获得与道德规范要求相符合的道德经验。
学生在道德实践中可以加深对道德规范及其意义的认识;亲眼看到自己的道德行为带来有益于他人或集体的积极后果,不仅能获得生动的道德情感体验,而且因道德知识一再被道德实践所证实,从而更加相信道德规范的正确性,这就为道德信念的建立打下了经验基础。
第三,培养学生道德判断能力,引导学生对自己和他人的行为做出道德评价。
结合具体的道德情境,对照道德准则的要求,对自己和他人的行为做出评价和反思,有利于道德经验得到概括和整合,从而增强道德观念对自己今后行为的支配力。
第四,获得社会反馈。
学生在集体中的行为经常会受到舆论的褒贬和教育者的奖惩,这种社会反馈一方面激发了学生按道德准则行动的动机;另一方面又不断向学生传递了关于道德行为价值的信息。
当学生看到自己因做出利他行为而赢得全班的尊重时,他就会对执行道德规范的必要性深信不疑。
为了形成道德信念,社会反馈的一致性非常重要。
如果对待学生的同一行为,社会反馈信息不一致,诸如学校的看法与家长的看法不一致,教师的观点与某些学生的观点不一致,就会给学生对道德知识的确证带来困难。
4.如何培养青少年的道德情感?答:第一,将学生的道德观念与一定的情绪体验结合起来。
这就要求教师在讲解道德知识时,要注意运用具体、典型的实例,以生动的、带有情绪色彩的言语表述,使学生在领会道德要求的同时,产生情绪体验。
第二,引导学生将道德认识付诸行动,从事道德实践。
如帮助社区的孤寡老人解决生活困难,与贫困地区学校学生开展心连心协作活动,从中获得直接的道德情感体验。
第三,利用优秀文艺作品,如故事、小说、戏剧、影视作品等引起学生情感的共鸣。
第四,引导学生对道德情境做出正确评价。
现代情绪心理学的研究表明,情绪是通过对刺激因素、认知因素和生理因素三方面信息的整合而产生的。
因此,在道德教育中,提供有关的背景信息,帮助学生对道德情境、人物、事件做出解释和评价,可以影响其道德情绪体验。
第五,重视教师的情绪感化作用。
教师对学生的爱是学生获得积极情感体验的源泉。
如果一个教师对一名后进生的错误行为进行严厉批评的同时,能对该学生在生活上给予关心,在学习上进行切实的帮助,对他所表现出的微小进步感到由衷的喜悦。
当学生认识到老师的善良愿望后,就会产生温暖、感激、信任等积极情感体验。
第六,开展移情训练,增强道德敏感性。
针对初二和高一学生,实施移情训练,所采取的“移情训练系列法”包括情绪追忆、情感换位、作品深化和作品评析四个方法。
结果表明该项训练能明显提高青少年学生的移情能力;青少年移情能力与其亲社会行为呈显著的正相关。
5.如何培养青少年的道德意志与道德行为?答:道德行为的形成涉及特定情境中行为动机的产生、道德行为方式的掌握、道德习惯的养成等多方面内容。
