计量经济学导论:ch07 多元回归分析:虚拟变量
d j系数含义可解释为:保持其他因素不变,信用等级为j
级的城市和信用等级为零级的城市之间在MBR上的差异。 其中,j 1, 2,3, 4。
问题:两种估计方法中,哪种方法更优?

例7.7 相貌吸引力对工资的影响
在劳动力市场中,除了存在性别歧视之外,还 可能存在相貌、身高等歧视。如果将样本相貌 分为三类:一般水平、低于一般水平、高于一 般水平,并以一般水平组作为基组,分别对男 人、女人估计方程得:
y = b0 + d0d + b1x + u
This can be interpreted as an intercept shift
If d = 0, then y = b0 + b1x + u If d = 1, then y = (b0 + d0) + b1x + u
The case of d = 0 is the base/benchmark group
虚拟变量与非虚拟变量之间也有交互作用,使 得出现不同的斜率。
female 0,男性组截距是b0,受教育的斜率是b1; female 1,女性组的截距是b0 d0,受教育的斜率是b1 d1。
24
25
我们关心的两个假设: ➢ 男性和女性受教育的回报是相同的。
H0:d1 0
➢ 受教育水平相同的男性和女性的平均工资相同。
将式7.13中的调整R 平方与把排名作为一个单独变量得到
的调整R 平方比较,前者是0.905,后者是0.836。所以,式
7.13 增加了回归的灵活性。 另外,式 7.13中所有其他变量都变得不显著了,联合显著性

ch07 数字音频工作站、调音台
数字音频技术数字音频工作站、调音台1610639528@文字内容来源于网络,如有侵权请联系邮箱内容概要•数字音频工作站功能与特点构成与分类•概念•数字音频工作站(Digital Audio Workstation,简称DAW)是一种用来处理、交换音频信息的计算机系统。
•它是随着数字音频技术的发展和计算机技术的突飞猛进,将两者相结合的新型设备。
•数字音频工作站的出现,实现了广播系统高质量的节目录制和自动化播出,同时也创造了更加良好高效的工作环境。
•特点•1.DAW在录音制作过程中无需大量模拟输入、输出接口及连线就能实现多轨录音的设想,节省了一些连接线及连接步骤,同时也节省时间,工作效率高。
•特点•2.DAW系统硬盘存取信息快、记录时间长。
•如在采样频率为44.1MHz,量化精度为20bit时,10G 的硬盘可记录20多小时,而DAT(Digital Audio Tape 数码音频磁带技术)记录时间一般为2小时。
•硬盘录音时间只受硬盘本身大小的限制(通常44.1kHz取样频率、16比特精度下1分钟双声道立体声信号需要10MB硬盘存储器)。
•特点•3.采用波形编辑,便于迅速、精确地找到编辑点,对轨道中音频素材的编辑、复制、移动、分割、合成十分方便并准确;•对音乐过度及编辑点能进行交叉淡化处理;•对声音有变速、变调的功能;•对声音进行任意编辑操作而对信号都没有损害。
•特点•4.随机存取编辑。
•因为信号记录在硬盘上,节目中任何点可以随即访问,不论它们以什么顺序纪录。
•无损编辑在丝毫不改变或影响原始录音文件的情况下允许信号片段安排在节目中的任何次序上。
一旦编辑结束,这些片段可以连续重放来产生一个演奏,或者个别的在一个指定的SMPTE时间码地址上重放。
•分类•常规可以分为两种:–专业数字音频工作站–组建数字音频工作站•分类•专业数字音频工作站•专业数字音频工作站是一套集录音机、调音台、和效果、表桥和显示器于一体的完整的音频录音及制作设备。

单片机前四章复习题答案
《单片机原理及应用》习题一、填空题1.单片机与普通计算机的不同之处在于其将_CPU__、存储器和__I/O_3部分集成于一块芯片之上。
2.CPU主要由运算器和控制器组成。
CPU中的布尔处理器用来处理位操作。
3.MSC-51系列单片机中,片内无ROM的机型是 8031 ,有4KB ROM的机型是_8051_,而有4KB EPROM 的机型是 8751 。
4.-32的补码为 B,补码B代表的真值为_-38__D。
5.原码数BFH=_-63_D,原码数6EH=_110_D。
6.100的补码=_64_H,-100的补码= 9C H7.在8031单片机内部,其RAM高端128个字节的地址空间称为特殊功能寄存器或SFR 区,但其中仅有_21_个字节有实际意义。
8.通常单片机上电复位时PC=_0000_H,SP=_07_H,通用寄存器则采用第_0_组,这一组寄存器的地址范围是从_00 H~_07_H。
9.若PSW为18H,则选取的是第_3__组通用寄存器。
10.8031单片机复位后R4所对应的存储单元地址为_04_H,因上电时PSW=_00_H。
11.若A中数据为63H,那么PSW的最低位(即奇偶位P)为_0_。
12.在微机系统中,CPU是按照程序计数器PC 来确定程序的执行顺序的。
13.在8031单片机中,使用P2、P0口传送地址信号,且使用了P0口来传送数据信号,这里采用的是总线复用技术。
14.堆栈遵循先进后出(或后进先出)的数据存储原则,针对堆栈的两种操作为_PUSH_和_POP_。
15.当8051地RST端上保持两个机器周期以上低电平时,8051即发生复位。
16.使用8031单片机时需将EA引脚接_低__电平,因为其片内无程序存储器。
17.8位机中的补码数80H和7EH的真值分别为_-128__和_127 。
18.配合实现“程序存储自动执行”的寄存器是_PC_,对其操作的一个特别之处是每取完一字节指令后PC内容会自动加1 。

错因:丙醛与丙酮互为同分异构体。
(3)欲检验CH2===CH—CHO分子中的官能团,应先检验“”后检验“—CHO”。
错因:检验“”一般用溴水或KMnO4(H+)溶液,而两试剂均可氧化“—CHO”,故应先检验“—CHO”,后检验“”。

中国计算机发展史
1958年,中科院计算所研制成功我国第一台小型电子管通用计算机103机(八一型),标志着我国第一台电子计算机的诞生。
1965年,中科院计算所研制成功第一台大型晶体管计算机109乙,之后推出109丙机,该机为两弹试验中发挥了重要作用;1974年,清华大学等单位联合设计、研制成功采用集成电路的DJS-130小型计算机,运算速度达每秒100万次;1983年,国防科技大学研制成功运算速度每秒上亿次的银河-I巨型机,这是我国高速计算机研制的一个重要里程碑;1985年,电子工业部计算机管理局研制成功与IBM PC机兼容的长城0520CH微机。
1992年,国防科技大学研究出银河-II通用并行巨型机,峰值速度达每秒4亿次浮点运算(相当于每秒10亿次基本运算操作),为共享主存储器的四处理机向量机,其向量中央处理机是采用中小规模集成电路自行设计的,总体上达到80年代中后期国际先进水平。
它主要用于中期天气预报;1993年,国家智能计算机研究开发中心(后成立北京市曙光计算机公司)研制成功曙光一号全对称共享存储多处理机,这是国内首次以基于超大规模集成电路的通用微处理器芯片和标准UNIX操作系统设计开发的并行计算机;1995年,曙光公司又推出了国内第一台具有大规模并行处理机(MPP)结构的并行机曙光1000(含36个处理机),峰值速度每秒25亿次浮点运算,实际运算速度上了每秒10亿次浮点运算这一高性能台阶。
曙光1000与美国Intel公司1990年推出的大规模并行机体系结构与实现技术相近,与国外的差距缩小到5年左右。
1997年,国防科大研制成功银河-III百亿次并行巨型计算机系统,采用可扩展分布共享存储并行处理体系结构,由130多个处理结点组成,峰值性能为每秒130亿次浮点运算,系统综合技术达到90年代中期国际先进水平。
1997至1999年,曙光公司先后在市场上推出具有机群结构(Cluster)的曙光1000A,曙光2000-I,曙光2000-II超级服务器,峰值计算速度已突破每秒1000亿次浮点运算,机器规模已超过160个处理机,1999年,国家并行计算机工程技术研究中心研制的神威I计算机通过了国家级验收,并在国家气象中心投入运行。

7.2.1 外部中断
• 外部中断 • 非屏蔽中断(NMI) • 中断请求信号:NMI线上的信号是边沿有 效的,高电平的有效宽度必须大于两个 时钟周期。 • 中断请求不受标志位IF的影响,立即被 CPU锁存起来。 • 优先权最高 • 当前指令执行完后,CPU立即响应。中断 类型为2 • 不需要中断响应周期INTA
7.2.1 外部中断
• 可屏蔽中断 • INTR线上的中断请求信号是电平有效的, 高电平的有效信号必须保持到当前指令 结束。中断请求信号来自可编程中断控 制器8259A。 • CPU根据IF来决定它是否响应INTR。IF=1, 开放中断;IF=0,关闭中断。 • STI使IF=1,CLI使IF=0
7.1 中断技术概述
• 计算机在执行主程序过程中,当某个 事件发生时,CPU暂时停止正在执行 的程序,而转去执行相应的处理程序, 处理完该事件后,以返回原程序继续 执行,这个过程就叫中断。 • 中断源 • 中断系统功能 • 中断形式

7.2.4 中断响应顺序
• NMI:CPU在当前指令执行完后,检测到NMI信 号有效时,CPU不需要上述两个中断响应总线 周期,而在内部自动产生中断类型2。 • 内部软件中断:中断类型码是规定好的,是 自动形成的。 • INT n:类型码由指令第二字节n 给定。
7.2.4 中断响应顺序
7.3.1 8259A的基本功能(5)
• 工作过程 • 当第一个INTA脉冲到来时,完成下列动作: • 使IRR的锁存功能失效。这样,在IR0-IR7线上的 中断请求信号就不予接收; • 使当前ISR中的相应位置1,以便为判优电路下一 次判优提供依据; • 使IRR相应位复位。 • 第二个INTA脉冲到来时,完成下列动作: • 使IRR的锁存功能有效; • 将中断类型码寄存器中的内容送到数据总线上, 供CPU读取; • 若8259A处于自动结束中断方式,则在该 脉冲结 束时,把当前ISR的相应位复位。
• 响应中断 • 8086在取得中断类型码后的处理过程是相同的,其顺 序为: • 把中断类型码乘4,作为中断矢量表的地址指针; • 把CPU的标志寄存器FR入栈保护(相当于执行指令 PUSHF); • 把陷阱标志TF的状态送到暂存器,接着使IF=0, TF=0,屏蔽新的INTR和单步中断; • 把主程序断点处的CS和IP值推入堆栈保护,先推入CS 值,后推入IP值; • 从中断矢量表中取中断服务程序入口地址的相应值, 先取CS值,后取IP值。 • CPU转向中断服务程序执行之。
