分别计算两种情况下的数据传输效率。
（知识点在：P33）解：长度为8B的应用层数据的数据传输效率：8/(8+20+60+18) ×100%=8/106×100%=7.55%长度为536B的应用层数据的数据传输效率：536/(536+20+60+18) ×100%=536/634×100%=84.54%8. 计算发送延时与传播延时。

语法和语法单位
第四章语法P86一、语法和语法单位1、语法规则P87-88 是指大家说话的时候必须遵守的习惯，是用词造句的规则，包括语法的组合规则和聚合规则。
（1）组合规则：是语法单位一个接着一个组合起来的规则（即谴词造句的规则），它是现实的，存在于话语中。
（2）聚合规则：指语法上能够出现在某个位置中的词形成一个聚合，即语法单位的归类规则（词类）。
它是潜在的，储存于人们的头脑中。
汉语中，有两大词类：实词：是能独立充当句法成分的词，意义比较实在，大多具有词汇意义，包括名词、动词、形容词、数词、量词、副词、代词七类；虚词：是不能独立充当句法成分的词，意义比较虚化，大多只有语法意义，表示结构、语气、链接等，包括介词、连词、语气词、助词、叹词、象声词六类。
2、语法单位P90 指能在组合的某一位置上被替换下来的片段，包括句子、词组（短语）、词、语素。
（1）语素：P92 是语言中最小的音义结合体。
其作用主要是构词。
根据语素在词中的不同作用把语素分成三类：***注意：词缀只能粘附在词根上构成新词，本身不能单独构成词。
（2）词P91 是造句时候能够独立运用的最小单位。
其主要作用是造句。
现代汉语中的词有两大词类。
（3）词组P91 是词的组合，他是句子里面作用相当于词而本身又是由词语构成的大于词的单位。
也叫短语。
词组可以分成两类：自由词组：即根据表达的需要临时作出的词语的组合。
固定词组：即词语的固定的组合，汉语中包括成语、谚语、歇后语、俗语等。
（4）句子P92 是语言中最大的语法单位，是交际中基本的表述单位。
从形式上看，其最大的特点是有一个完整的语调，按其语气可分为陈述、疑问、祈使、感叹等四种句型。
二、组合规则P941、语法的组合规则包括两个规则：词法：指语素组合成词的规则和词语的变化规则；句法：指词语组合成句子的规则。
2、词的基本组合关系P95（1）派生词的派生构词法：由词根语素和词缀语素相组合的构词规则。
（2）复合词的基本组合关系：3、语法结构的意义和形式P98（《学习指导书》P70）（1）词汇意义：是指词语的意义的总和；语法意义：是指词进入语法组合之后由语法结构所赋予的词义之外的意义。
计算机组成原理(第三版)课后答案
计算机是一种能自动地、高速地对各种数字化信息进行运算处理的电子设备。
1．2冯诺依曼计算机体系结构的基本思想是存储程序，也就是将用指令序列描述的解题程序与原始数据一起存储到计算机中。
计算机只要一启动，就能自动地取出一条条指令并执行之，直至程序执行完毕，得到计算结果为止。
按此思想设计的计算机硬件系统包含：运算器、控制器、存储器、输入设备和输出设备。

语法练习参考答案
倒装【答案解析】1. B. 因为以否定词或半否定词开头的句子，要用部分倒装，排除A和D。
另外，no sooner…than…(一…就…)是固定答搭配，且no sooner分句中的谓语通常用过去完成时，而than分句中的谓语用一般过去时。
2. B. 因为由前句判现在还没有去舞会，是将来时态；又因为在条件状语从句中要用一般现在时代替一般将来时，所以正确答案是B。
If she does, so will mine. =If she goes to the ball, my girl friend will go, too.3. D. 当not only…but also…不是连接两个不同的主语时，以not only开头的句子要用部分倒装，排除A和C。
又因为it is necessary后的that从句一般要用should +动词原形，所以只有D正确。
4. A. 主句是名词时，其后要倒装，但是代词时不用倒装。
5. A. 因为是nowhere否定词，以否定词开头的句子，要用部分否定。
6. A. 因为以否定词not until开头的句子要用部分倒装，排除B和D；又因为2003年12月是过去时间，用一般过去时，所以选A。
7. A. 因为“only+状语”放在句首时，句子要用部分倒装；但这个“状语”是从句时，从句不要倒装，所以只有A正确。
8. D. 因为“nor +情态动词、助动词或be+主语”表示“…也不”之意，又由前文的saw可知hear 也是一般过去时态，所以用助动词did。
10. C. 因为以here, there, up, down, in, out, now, then, away, off等副词开头时，常用完全倒装。
句意是：我们要坐的公共汽车走了，我们将不得不等下一辆。
11. B. 因为这里不是表示“…也一样”，而是对对方所言表示赞同：“的确如此”，所以不用倒装。
12. D. 句子以副词down开头，本来应该要用完全倒装，但由于主语为代词，所以不用倒装。

汽轮机原理(热工机械)课后习题及答案
汽轮机原理(热工机械)课后习题及答案绪论1.汽轮机的工作单元由哪些部件组成？喷嘴，动叶。
2.何为纯冲动级？反动级？带反动度的冲动级？复速级？蒸汽在纯冲动级、反动级、复速级流通部分内压力和速度如何变化？纯冲动级：?m?0 p1?p2w1?w2?hb?0?hn??ht**反动级：蒸汽在级中的理想焓降平均分配到喷嘴和动叶中级。
p1?p2?h??hb?*n?ht2* ?m?0.5?hn??hb带反动度的冲动级：具有一定反动度的冲动级，简称冲动级 ?m?0.05~0.20 p1?p2复速级：只有一列喷嘴，后面有若干列动叶的级称为速度级，两列动叶的双列速度级纯冲动级反动级复速级动叶不变喷嘴动叶喷嘴动叶喷嘴压力减小不变减小减小减小速度增大减小增大减小增大减-不变-减 3.级的反动度如何定义？如何根据反动度进行级的划分？级的反动度表示蒸汽在动叶通道内膨胀程度大小的指标；蒸汽在动叶通道内的理想焓降与喷嘴滞止理想焓降和动叶通道内的理想焓降之和的比值。
根据蒸汽在汽轮机内能量转换的特点，可将汽轮机的级分为纯冲动级、反动级、带反动度的冲动级和复速级等几种。
4.在动叶上如果只存在反动作用力，冲动作用力不存在能实现吗？为什么？不能。
冲动-反冲第一章1.（1）当蒸汽在喷嘴中流动时，为了使喷嘴出口速度进一步提高直到获得超音速汽流，不能采用缩小流通孔道截面积的方法？dAA??dCC(1?M) M?2Ca（M>1时，A,C同方向增减）当地速度低于音速时，M <1，面积减小则速度增大，压强减小；面积增大则速度减小压强增大；当地速度高于音速时，M >1，面积减小则速度减小，压强增大；面积增大则速度增大压强减小；超音速条件下，密度下降比速度增大快（2）蒸汽在喷嘴中流动时，对于亚音速和超音速汽流，当速度降低时，压力都将升高？是。
伯努利方程，动量方程。
2.什么是喷嘴的速度系数？它与哪些因素有关？喷嘴的最小高度是多少？为什么？ ??C1C1t，喷嘴出口实际速度与理想速度比值。
