模块四PLC应用指令的应用任务一8盏流水灯控制程序思考和练习1.什么是位元件？什么是字元件？两者有什么区别？答：只具有接通（ON或1）或断开（OFF或0）两种状态的元件称为位元件。

将多个位元件按一定的规律组合起来就称为字元件，也称位组件。

位元件只能单个取用，而字元件是位元件的组合所以只用一条指令即可同时对多个字元件进行操作。

2.位元件如何组成字元件？请举例说明。

答：位元件组合以KnP的形式表示，每组由4个连续的位元件组成，称为位元件，其中P 为位元件的首地址，n为组数（n＝1～8）。

4个单元K4组成16位操作数，如K4M10表示由M25~ M10组成的16位数据。

3.数据寄存器有哪些类型?具有什么特点?试简要说明。

32位数据寄存器如何组成？答：数据寄存器可分为：通用数据寄存器、锁存数据寄存器、文件寄存器、特殊数据寄存器、变址寄存器。

锁存数据寄存器有断电保持功能，文件寄存器只能用外部设备进行写入操作，特殊数据寄存器用来监控PLC内部的各种工作方式和元件，例如电池电压、扫描时间等，变址寄存器（V、Z）除了和普通的数据寄存器有相同的使用方法外，还常用于修改器件的地址编号。

32位数据寄存器由两个16为数据寄存器组成。

4.应用指令的组成要素有几个？其执行方式有几种？其操作数有几类？答：应用指令的组成要素共有五个（1）应用指令编号（2）助记符（3）数据长度（4）执行形式（5）操作数。

应用指令有脉冲执行型和连续执行型两种。

操作数分为源操作数、目标操作数和其它操作数。

5. 试问如下软元件为何种软元件？由几位组成？X1、D20、S20、K4X0、V2、X10、K2Y0、M19答：X1、S20、X10、M19是位元件；D20、K4X0、V2、K2Y0是字元件；D20、V2是16位数据寄存器，K4X0是16位、K2Y0是8位。

6.执行指令语句“MOV K5 K1Y0”后，Y0～Y3的位状态是什么？答：Y0~Y3的状态是“0101”7.执行指令语句“DMOV H5AA55 D0”后，D0、D1中存储的数据各是多少？答：D1存储的数据是（0000 0000 0000 0101），D0存储的数据是（1010 1010 0101 0101）8.试用MOV指令编写电动机Y-△降压起动程序。

When comparison is made between different aspects of the same object or between different aspects of different objects, the clause does not usually allow ellipsis: Mary is cleverer than Jane is pretty. (The degree of cleverness is greater than that of prettiness) The house is taller than it is wide. (The height is greater than its width)。

《机械制造技术基础》部分习题参考解答第四章机械加工质量及其控制4-1什么是主轴回转精度？为什么外圆磨床头夹中的顶尖不随工件一起回转，而车床主轴箱中的顶尖则是随工件一起回转的？解：主轴回转精度——主轴实际回转轴线与理想回转轴线的差值表示主轴回转精度，它分为主轴径向圆跳动、轴向圆跳动和角度摆动。

车床主轴顶尖随工件回转是因为车床加工精度比磨床要求低，随工件回转可减小摩擦力；外圆磨床头夹中的顶尖不随工件一起回转是因为磨床加工精度要求高，顶尖不转可消除主轴回转产生的误差。

4-2 在镗床上镗孔时（刀具作旋转主运动，工件作进给运动），试分析加工表面产生椭圆形误差的原因。

答：在镗床上镗孔时，由于切削力F的作用方向随主轴的回转而回转，在F作用下，主轴总是以支承轴颈某一部位与轴承内表面接触，轴承内表面圆度误差将反映为主轴径向圆跳动，轴承内表面若为椭圆则镗削的工件表面就会产生椭圆误差。

4-3为什么卧式车床床身导轨在水平面内的直线度要求高于垂直面内的直线度要求？答：导轨在水平面方向是误差敏感方向，导轨垂直面是误差不敏感方向，故水平面内的直线度要求高于垂直面内的直线度要求。

4-4某车床导轨在水平面内的直线度误差为0.015/1000mm，在垂直面内的直线度误差为0.025/1000mm，欲在此车床上车削直径为φ60mm、长度为150mm的工件，试计算被加工工件由导轨几何误差引起的圆柱度误差。

解：根据p152关于机床导轨误差的分析，可知在机床导轨水平面是误差敏感方向，导轨垂直面是误差不敏感方向。

水平面内：0.0151500.002251000R y∆=∆=⨯=mm；垂直面内：227()0.025150/60 2.341021000zRR-∆⎛⎫∆==⨯=⨯⎪⎝⎭mm，非常小可忽略不计。

所以，该工件由导轨几何误差引起的圆柱度误差0.00225R∆=mm。

4-5 在车床上精车一批直径为φ60mm、长为1200mm的长轴外圆。

已知：工件材料为45钢；切削用量为：v c=120m/min，a p=0.4mm, f =0.2mm/r; 刀具材料为YT15。

第一章思考题1． 试用简练的语言说明导热、对流换热及辐射换热三种热传递方式之间的联系和区别。

答：导热和对流的区别在于：物体内部依靠微观粒子的热运动而产生的热量传递现象，称为导热；对流则是流体各部分之间发生宏观相对位移及冷热流体的相互掺混。

联系是：在发生对流换热的同时必然伴生有导热。

导热、对流这两种热量传递方式，只有在物质存在的条件下才能实现，而辐射可以在真空中传播，辐射换热时不仅有能量的转移还伴有能量形式的转换。

2． 以热流密度表示的傅立叶定律、牛顿冷却公式及斯忒藩－玻耳兹曼定律是应当熟记的传热学公式。

试写出这三个公式并说明其中每一个符号及其意义。

答：① 傅立叶定律：dx dtq λ-=，其中，q －热流密度；λ－导热系数；dx dt －沿x 方向的温度变化率，“－”表示热量传递的方向是沿着温度降低的方向。

② 牛顿冷却公式：)(f w t t h q -=，其中，q －热流密度；h －表面传热系数；w t －固体表面温度；f t －流体的温度。

③ 斯忒藩－玻耳兹曼定律：4T q σ=，其中，q －热流密度；σ－斯忒藩－玻耳兹曼常数；T －辐射物体的热力学温度。

3． 导热系数、表面传热系数及传热系数的单位各是什么？哪些是物性参数，哪些与过程有关？答：① 导热系数的单位是：W/(m.K)；② 表面传热系数的单位是：W/(m 2.K)；③ 传热系数的单位是：W/(m 2.K)。

这三个参数中，只有导热系数是物性参数，其它均与过程有关。

4． 当热量从壁面一侧的流体穿过壁面传给另一侧的流体时，冷、热流体之间的换热量可以通过其中任何一个环节来计算（过程是稳态的），但本章中又引入了传热方程式，并说它是“换热器热工计算的基本公式”。

试分析引入传热方程式的工程实用意义。

答：因为在许多工业换热设备中，进行热量交换的冷、热流体也常处于固体壁面的两侧，是工程技术中经常遇到的一种典型热量传递过程。

5． 用铝制的水壶烧开水时，尽管炉火很旺，但水壶仍然安然无恙。
