宏观经济学思考题及参考答案

宏观经济学思考题及参考答案(1) 第四章 基本概念:潜在GDP,总供给,总需求,AS曲线,AD曲线。 思考题 1、宏观经济学的主要目标是什么?写出每个主要目标的简短定义。请详细解释 为什么每一个目标都十分重要。 答:宏观经济学目标主要有四个:充分就业、物价稳定、经济增长和国际收支平衡。 (1)充分就业的本义是指所有资源得到充分利用,目前主要用人力资源作为充分就业的标准;充分就业本不是指百分之百的就业,一般地说充分就业允许的失业范畴为4%。只有经济实现了充分就业,一国经济才能生产出潜在的GDP,从而使一国拥有更多的收入用于提高一国的福利水平。 (2)物价稳定,即把通胀率维持在低而稳定的水平上。物价稳定是指一般物价水平(即总物价水平)的稳定;物价稳定并不是指通货膨胀率为零的状态,而是维持一种能为社会所接受的低而稳定的通货膨胀率的经济状态,一般指通货膨胀率为百分之十以下。物价稳定可以防止经济的剧烈波动,防止各种扭曲对经济造成负面影响。 (3)经济增长是指保持合意的经济增长率。经济增长是指单纯的生产增长,经济增长率并不是越高越好,经济增长的同时必须带来经济发展;经济增长率一般是用实际国民生产总值的年平均增长率来衡量的。只有经济不断的增长,才能满足人类无限的欲望。 (4)国际收支平衡是指国际收支既无赤字又无盈余的状态。国际收支平衡是一国对外经济目标,必须注意和国内目标的配合使用;正确处理国内目标与国际目标的矛盾。在开放经济下,一国与他国来往日益密切,保持国际收支的基本平衡,才能使一国避免受到他国经济波动带来的负面影响。 3,题略 答:a.石油价格大幅度上涨,作为一种不利的供给冲击,将会使增加企业的生产成本,从而使总供给减少,总供给曲线AS将向左上方移动。 b.一项削减国防开支的裁军协议,而与此同时,政府没有采取减税或者增加政府支出的政策,则将减少一国的总需求水平,从而使总需求曲线AD向左下方移动。 c.潜在产出水平的增加,将有效提高一国所能生产出的商品和劳务水平,从而使总供给曲线AS向右下方移动。 d.放松银根使得利率降低,这将有效刺激经济中的投资需求等,从而使总需求增加,总需求曲线AD向右上方移动。 第五章 基本概念:GDP,名义GDP,实际GDP,NDP,DI,CPI,PPI。 思考题: 5.为什么下列各项不被计入美国的GDP之中? a优秀的厨师在自己家里烹制膳食; b购买一块土地; c购买一幅伦勃朗的绘画真品; d某人在2009年播放一张2005年录制的CD所获得的价值; e电力公司排放的污染物对房屋和庄稼的损害;

思考题与习题答案

思考题与习题 1 1- 1 回答以下问题: ( 1)半导体材料具有哪些主要特性? (2) 分析杂质半导体中多数载流子和少数载流子的来源; (3) P 型半导体中空穴的数量远多于自由电子, N 型半 导体中自由电子的数量远多于空穴, 为什么它们对外却都呈电中性? (4) 已知温度为15C 时,PN 结的反向饱和电流 I s 10 A 。当温度为35 C 时,该PN 结 的反向饱和 电流I s 大约为多大? ( 5)试比较二极管在 Q 点处直流电阻和交流电阻的大小。 解: ( 1)半导体的导电能力会随着温度、光照的变化或掺入杂质浓度的多少而发生显着改变, 即半导体具 有热敏特性、光敏特性和掺杂特性。 ( 2)杂质半导体中的多数载流子是由杂质原子提供的,例如 供一个自由电子,P 型半导体中一个杂质原子提供一个空穴, 浓度;少数载流子则是由热激发产生的。 (3) 尽管P 型半导体中空穴浓度远大于自由电子浓度,但 P 型半导体中,掺杂的杂质原子因获得一个价电子而变成带负电的杂 质离子(但不能移动),价 电子离开后的空位变成了空穴,两者的电量相互抵消,杂质半导体从总体上来说仍是电中性的。 同理, N 型半导体中虽然自由电子浓度远大于空穴浓度,但 N 型半导体也是电中性的。 (4) 由于温度每升高10 C ,PN 结的反向饱和电流约增大 1倍,因此温度为 35C 时,反向 饱和电流为 (5) 二极管在 Q 点处的直流电阻为 交流电阻为 式中U D 为二极管两端的直流电压, U D U on ,I D 为二极管上流过的直流电流, U T 为温度的 电压当量,常温下 U T 26mV ,可见 r d R D 。 1- 2 理想二极管组成的电路如题 1- 2图所示。试判断图中二极管是导通还是截止,并确定 各电路的输 出电压。 解 理想二极管导通时的正向压降为零, 截止时的反向电流为零。 本题应首先判断二极管的工 作状 态,再进一步求解输出电压。二极管工作状态的一般判断方法是:断开二极管, 求解其端口 电压;若该电压使二极管正偏, 则导通; 若反偏, 则截止。 当电路中有两只或两只以上二极管时, 可分别应用该方法判断每只二极管的工作状态。 需要注意的是, 当多只二极管的阳极相连 (共阳 极接法)时,阴极电位最低的管子将优先导通;同理,当多只二极管的阴极相连(共阴极接法) 时,阳极电位最高的管子将优先导通。 (a) 断开二极管 D ,阳极电位为12V ,阴极电位为6V ,故导通。输岀电压 U O 12V 。 (b) 断开二极管 D 1、D 2, D 1、D 2为共阴极接法,其阴极电位均为 6V ,而D 1的阳极电位 为9V , D 2的阳极电位为5V ,故D 1优先导通,将 D 2的阴极电位钳制在 7.5V ,D 2因反向偏置而 截止。输岀电压 U O 7.5V 。 N 型半导体中一个杂质原子提 因此 多子浓度约等于所掺入的杂质 P 型半导体本身不带电。因为在

第三章思考题及答案

第三章思考题 刚体一般是由n (n 是一个很大得数目)个质点组成。为什么刚体的独立变量却不是3n 而是6或者更少 何谓物体的重心他和重心是不是 总是重合在一起的 试讨论图形的几何中心,质心和重心重合在一起的条件。 简化中心改变时,主矢和主矩是不是也随着改变如果要改变,会不会影响刚体的运动 已知一匀质棒,当它绕过其一端并垂直于棒的轴转动时,转动惯量为23 1 ml ,m 为棒的质量,l 为棒长。 问此棒绕通过离棒端为l 41且与上述轴线平行的另一轴线转动时,转动惯量是不是等于2 24131?? ? ??+l m ml 为什么 如果两条平行线中没有一条是通过质心的,那么平行轴定理式(3.5.12)能否应用如不能,可否加以修改后再用 在平面平行运动中,基点既然可以任意选择,你觉得选择那些特殊点作为基点比较好好处在哪里又在(3.7.1)及()两式中,哪些量与基点有关哪些量与基点无关 转动瞬心在无穷远处,意味着什么 刚体做平面平行运动时,能否对转动瞬心应用动量矩定理写出它的动力学方程为什么 当圆柱体以匀加速度自斜面滚下时,为什么用机械能守恒定律不能求出圆柱体和斜面之间的反作用力此时摩擦阻力所做的功为什么不列入是不是我们必须假定没有摩擦力没有摩擦力,圆柱体能不能滚 圆柱体沿斜面无滑动滚下时,它的线加速度与圆柱体的转动惯量有关,这是为什么但圆柱体沿斜面既滚且滑向下运动时,它的线加速度则与转动惯量无关这又是为什么 刚体做怎样的运动时,刚体内任一点的线速度才可以写为r ω?这时r 是不是等于该质点到转动轴的垂直距离为什么 刚体绕固定点转动时,r ω ?dt d 为什么叫转动加速度而不叫切向加速度又()r ωω??为什么叫向轴加速度而不叫向心加速度 在欧勒动力学方程中,既然坐标轴是固定在刚体上,随着刚体一起转动,为什么我们还可以用这种坐标系来研究刚体的运动 欧勒动力学方程中的第二项()21I I -y x ωω等是怎样产生的它的物理意义又是什么 第三章思考题解答 答:确定一质点在空间中得位置需要3个独立变量,只要确定了不共线三点的位置刚体的位置也就确定了,故须九个独立变量,但刚体不变形,此三点中人二点的连线长度不变,即有三个约束方程,所以
