学自动化的

解题思路：首先对物体进行受力分析，看物体受到几个力的作用，然后根据力的示意图的定义，将物体所受力的方向、作用点表示出来即可．

物体受到重力和支持力作用，由于物体沿水平向右做加速运动，物体相对于传送带有向左的运动趋势，所以物体受到向右的摩擦力，所以物体共受三个力作用：重力、支持力和摩擦力；
重力方向竖直向下，作用点在重心，支持力方向竖直向上，作用点也画在重心上，摩擦力方向水平向右，作用点也画在重心上，故工件受到的重力、支持力和摩擦力的示意图如图：

点评：
本题考点： 力的示意图；力与运动的关系．

考点点评： 画力的示意图，就是用一条带箭头线段表示出力的三要素，所以要先正确分析力的大小、方向和作用点，再根据力的示意图的要求作出力的示意图．

解题思路：找中位数要把数据按从小到大的顺序排列，位于最中间的一个数或两个数的平均数为中位数．

题目中数据共有12个，
故中位数是按从小到大排列后第6，第7两个数的平均数作为中位数，
故这组数据的中位数是[1/2]×（28+28）=28．
故填28．

点评：
本题考点： 中位数．

考点点评： 本题属于基础题，考查了确定一组数据的中位数的能力．
中位数是将一组数据从小到大（或从大到小）重新排列后，最中间的那个数（或最中间两个数的平均数），叫做这组数据的中位数．
注意：找中位数的时候一定要先排好顺序，然后再根据奇数和偶数个来确定中位数，如果数据有奇数个，则正中间的数字即为所求．如果是偶数个则找中间两位数的平均数．

顾名思义,类似于词缀的用途的几个字符
词缀有前缀,后缀.
最好提供几个例子
很惭愧,词法方面我是外行.
看了这些例子谈点我的感受吧：这些词是复合词,词缀类似于英语的后缀-ize/ization,-ist,-er,
以 工业化 为例(同举例中所有其他的词一样),可作为名词,工业 修饰 化 这一动作/状态,如同定语修饰主语,化 才是词的中心；还可作动词,仍旧是 工业 修饰 化 这一动作过程,如同状语修饰谓语.
这样看来 类词缀 可能指那些形式上是词缀,意义上却是词的中心,可单独成词.
不好意思,确实班门弄斧了.
找到定义了!类词缀：位置基本固定,意义正在类化,读音保持不变的词缀,它是由词根向词缀真词缀的转化的中间过度形式.

办公自动化（OA:Office Automation）是在企业或其他机构内部为提高工作效率而应用的一种应用软件.
办公自动化主要面向企业或机构的办公应用,基于Internet/Intranet,由组织内部人员共同使用.
办公自动化系统(企业OA)通常包括以下主要部分：工作流、协同工作、知识管理、公文处理、行政办公等.
目前的办公自动化已经普遍采用浏览器/服务器方式(B/S).其采用的典型技术有ASP、.NET、JAVA、Domino等.
Office automation refers to the varied computer machinery and software used to digitally create,collect,store,manipulate,and relay office information needed for accomplishing basic tasks and goals.Raw data storage,electronic transfer,and the management of electronic business information comprise the basic activities of an office automation system.Office Automation helps in optimise or automate existing office procedures.
The backbone of office automation is a LAN,which allows users to transmit data,mail and even voice across the network.All office functions,including dictation,typing,filing,copying,fax,Telex,microfilm and records management,telephone and telephone switchboard operations,fall into this category.Office automation was a popular term in the 1970s and 1980s as the desktop computer exploded onto the scene.

解题思路：根据极差的定义，找出最大值与最小值即可求得．

由题意可知，极差为24-18=6．
故答案为：6．

点评：
本题考点： 极差．

考点点评： 此题主要考查了极差的计算，极差反映了一组数据变化范围的大小，求极差的方法是用一组数据中的最大值减去最小值．

（z）∵P=UI
∴路灯正常工作图电流为I=[P/U]=[4它z/22它V]≈它.z少A；
（2）查表可知，当光照度为z5勒克斯时，光敏电阻R₂图阻值为2它Ω
电路电流为I=
U2
R2=[3V/2它Ω]=它.z5A，
定值电阻两端电压为U_z=U-U₂=4.5V-3V=z.5V
定值电阻阻值为R_z=
Uz
I=[z.5V/它.z5A]=z它Ω；
（3）因为电池组电压下降会导致光敏电阻两端电压下降，串联电路中R_z阻值不变，要使光敏电阻R₂两端电压达到3伏，光敏电阻R₂图阻值必须增大，所以要在光照度更小时才能实现．
故答案为：
（z）它.z少；
（2）z它Ω；
（3）因为电池组电压下降会导致光敏电阻两端电压下降，串联电路中R_z阻值不变，要使光敏电阻R₂两端电压达到3伏，光敏电阻R₂图阻值必须增大，所以要在光照度更小时才能实现．

解题思路：（1）力臂是从支点到力的作用线的距离，由支点向力的作用线引垂线，垂线段的长度即为力臂；盖对起子的力即为阻力．
（2）首先对工件进行受力分析，因为工件与传送带一起匀速运动，所以它们之间没有发生相对运动，是相对静止的，则没有摩擦力的作用，工件只受重力和传送带的支持力的作用．
（3）物体对斜面的压力，作用在斜面上，作用点就画在斜面上，方向是垂直斜面并且指向斜面内部；
（4）漂浮的小球在水中受重力与浮力的作用，重力的方向竖直向下，浮力的方向竖直向上，并且二力是一对平衡力．

（1）首先在F₁的方向上做出力F₁的作用线，然后从支点O向F₁的作用线引垂线，垂线段的长度即为力臂L₁．
F₁使起子沿逆时针转动，其中盖对起子的力阻碍了起子的转动，所以是阻力F₂，方向竖直向下，如下图所示：

（2）工件受到自身重力G和传送带的支持力的作用，二者大小相等、方向相反，是一对平衡力，作用点都选择在物体的重心，如图所示．

（3）物体对斜面的压力的作用点在物体与斜面接触面的中点处，过此点与斜面垂直向下的力，即为压力，如下图：

（4）过球心分别沿竖直向下和竖直向上的方向画一条带箭头的线段，用符号G和F_浮表示，如图所示：

点评：
本题考点： 力臂的画法；力的示意图．

考点点评： 画力的示意图时，重点是判断出物体受力的三要素，还要考虑物体所处的运动状态，当物体静止或做匀速直线运动时，受到的力是平衡力．本题中第二问，工件受到了重力与支持力的作用，比较容易确定，难点在于要通过工件所处的运动状态，分析其是否受到摩擦力的作用，这是本题的难点和易错点，应引起我们的注意．

3(2)正确(1)、(3)、(4)不清楚。

（1）根据安全用电的原则可知，当灯泡不工作时其两端应无电，故A是火线、B是零线；
（2）天暗时自动电灯亮说明此时照明电路闭合即衔铁断开，由图可知此时电磁铁的磁性减弱即电路中的电流变小，根据R=[U/I]可知电路中的电阻变大即此时光敏电阻的阻值变大；反之，天亮时光敏电阻的阻值变小，所以他选择的光敏电阻阻值大小应随光照强度的增加而减小．
（3）当滑片位于b端时，电路为光敏电阻的简单电路，电压表测电源的电压，由图可知电源的电压U=12V；
当滑片位于a端时滑动变阻器与光敏电阻串联，电压表测光敏电阻两端的电压，电流表测电路中的电流，
由表可知，I=0.1A，U_光敏=2V，
则电路中的总电阻R_总=[U/I]=[12V/0.1A]=120Ω，
光敏电阻的阻值R_光敏=
U光敏
I=[2V/0.1A]=20Ω，
滑动变阻器的最大阻值R_ab=R_总-R_光敏=120Ω-20Ω=100Ω．
故答案为：A；减小；100．

A control system is designed to control the dynamic behavior( the time response) of a plant subject to commands or disturbances. The designer should be fully aware, however, of the role of the steady equations and errors in the overall process, as well as their influence on the dynamic behavior of the plant.
控制系统设计就是使装置在有指令信号或者干扰时有满意的行为（时域响应）.设计者必须清楚地知道整个过程的稳态方程和误差,以及他们对装置的动态性能的影响.
An accuracy of a system is a measure of how well it follows commands. It is an important performance criterion; a guidance system that cannot place spacecraft on a suitable trajectory is obviously useless no matter how well-behaved its transient response.
衡量系统的精度之一,就是其如何跟踪给定命令.这是一项重要的性能指标.一个导航系统如果不能将飞行器置于合适的轨迹,那么无论有多好的动态性能,都是没有用.
Actual system are also subjected to undesirable inputs, such as noise in command inputs and disturbances arising from changes in the plant parameters or changes in the environment in which the plant is operating. Noise inputs that enter the system with the command input require filtering techniques to remove or suppress them without affecting the command input itself. We shall limit our discussion to disturbance inputs which enter the system at the plant rather than at the controller.
实际系统总是容易受到不希望的输入干扰,例如, 命令输入中的噪声以及由于参数改变在被控对象中产生的干扰或者被控对象工作环境变化产生的干扰.随着命令输入进入系统的噪声输入需要滤波器进行驱除或者抑制并不对输入信号产生影响.我们将限于讨论通过被控对象进行系统的噪声而不讨论通过控制器进入系统的噪声.
It is often difficult to minimize both components of the error simultaneously. Obviously, it is necessary to have some knowledge as to the nature of probable disturbance inputs. Both error terms of Eq.(2-2B-7) can be set equal to zero by introducing an integrator into the controller. This additional integrator increases the type of the system ( from 1 to 2, for example) , thus eliminating the velocity error, and by being introduced ahead of the point of entry of the disturbance into the system, eliminates the steady-state error resulting from a step in the disturbance input. This additional integrator must be accompanied by at least one zero if the system is to remain stable.
通常同时将误差的两个部分最小化是困难的.很明显,具有适当的干扰输入特性的一些知识是很有必要的.方程2-2B-7的两个误差项都能通过在控制器中加入积分器而消除.这些附加的积分器增加了系统的型（例如,从1型系统变为2型系统）,因此可以消除速度误差,并通过在系统扰动进入点之前引入积分环节,可以消除由输入信号中包含的阶跃扰动引起的稳态误差.如果要保持系统稳定该附加的积分器必须相应增加至少一个零点.
