习题11. 图论诞生于七桥问题。
出生于瑞士的伟大数学家欧拉(Leonhard Euler ,1707—1783)提出并解决了该问题。
七桥问题是这样描述的:一个人是否能在一次步行中穿越哥尼斯堡(现在叫加里宁格勒,在波罗的海南岸)城中全部的七座桥后回到起点,且每座桥只经过一次,图是这条河以及河上的两个岛和七座桥的草图。
请将该问题的数据模型抽象出来,并判断此问题是否有解。
七桥问题属于一笔画问题。
输入:一个起点输出:相同的点1, 一次步行2, 经过七座桥,且每次只经历过一次3, 回到起点该问题无解:能一笔画的图形只有两类:一类是所有的点都是偶点。
另一类是只有二个奇点的图形。
2.在欧几里德提出的欧几里德算法中(即最初的欧几里德算法)用的不是除法而是减法。
请用伪代码描述这个版本的欧几里德算法=m-n2.循环直到r=0m=nn=rr=m-n3 输出m3.设计算法求数组中相差最小的两个元素(称为最接近数)的差。
要求分别给出伪代码和C++描述。
编写程序,求n 至少为多大时,n 个“1”组成的整数能被2013整除。
#include<iostream>using namespace std;int main(){double value=0;图 七桥问题for(int n=1;n<=10000 ;++n){value=value*10+1;if(value%2013==0){cout<<"n至少为:"<<n<<endl;break;}}计算π值的问题能精确求解吗?编写程序,求解满足给定精度要求的π值#include <iostream>using namespace std;int main (){double a,b;double arctan(double x);圣经上说:神6天创造天地万有,第7日安歇。
为什么是6天呢?任何一个自然数的因数中都有1和它本身,所有小于它本身的因数称为这个数的真因数,如果一个自然数的真因数之和等于它本身,这个自然数称为完美数。

– 1 –– 2 – – 3 –P/N: 1802071100114UC-7112 Plus/7112/7110 Quick Installation GuideFifth Edition, January 20141. OverviewThe Moxa UC-7112 Plus, UC-7112, and UC-7110 are mini size RISC-based ready-to-run embedded computers that feature dual 10/100 Mbps Ethernet ports and two RS-232/422/485 serial ports in a built-in µClinux ARM9 box. In addition, the UC-7112 provides an internal SD socket for storage expansion, to offer highperformance communication and unlimited storage in a super compact, palm-size box. The UC-7112 Plus, UC-7112, andUC-7110 are the right solutions for embedded applications that use a lot of memory, but that must be housed in a small physical space without sacrificing performance.2. Package ChecklistBefore installing the UC-7112 Plus/7112/7110, verify that the package contains the following items: • 1 UC-7112 Plus, UC-7112,or UC-7110 • Quick Installation Guide • Document & Software CD• Cross-over Ethernet cable: RJ45 to RJ45, 100 cm • Console port cable: CBL-4PINDB9F-100(4-pin header to female DB9 cable, 100 cm) • Universal Power Adaptor•Product Warranty StatementOptional Accessories •DK-35ADIN-Rail Mounting Kit (35 mm)NOTE: Please notify your sales representative if any of the above items are missing or damaged.3. Hardware IntroductionLED IndicatorsThe following LED indicators are located on the top panel of the UC-7112 Plus/7112/7110.UC-7112 Plus/7112/7110 Top ViewThe top view of the UC-7112 is shown in the following figure. The UC-7112 Plus and UC-7110 look similar, except that the UC-7110 does not have an internal SD slot.UC-7112 Plus/7112/7110 DimensionsThe dimensions of the three products are shown in the following figure.4. Hardware Installation ProcedureSTEP 1: Remove the UC from the box and attach the poweradaptor.STEP 2: Connect the UC’s serial console cable to your PC’s RS-232COM port for initial setup through the console terminal.STEP 3: Connect the UC to a network. Use a standardstraight-through Ethernet cable to connect to a hub or switch. When setting up or testing the UC, you might find it convenient to connect directly to your computer’s Ethernet port. In this case, use a cross-over Ethernet cable.STEP 4: Install Secure Digital (SD) Memory Card (UC-7112and UC-7112 Plus only)To install an additional SD card, you must first remove the UC-7112’s outer cover to access the slot. The internal SD socket is located at the back side of the UC-7112 on the bottom board; you can find the SD socket on the right, a little lower than the cover screw. Plug the SD card directly into the socket. To remove the card, press it in first, and then remove your finger. The card will pop out enough to allow you to remove it.STEP 5: Placement OptionsIn addition to placing the UC on a desktop or other horizontal surface, you may also make use of the DIN-Rail or Wall Mount options, as illustrated here.Wall MountDIN-Rail5. Software Installation ProcedureSTEP 1: Insert the UC’s CD-ROM into your Windows or Linux PC,and then use Acrobat Reader to read the UC-7112/7110 Series User’s Manual.STEP 2: Install the UC’s tool chain, which is on the CD-ROM. Thetool chain consists of the following components:1. UC Finder: Broadcast search for the UC’s IP address on your LAN. The UC supports both Windows and Linux environments.2. Cross Compiler: Arm-elf-gcc for µClinux platforms (UC-7112/7110), and Arm-linux-gcc for embedded Linux platform (UC-7112 Plus). Both options are C/C++ PC cross compilers, which are gcc compilers that run on an x86 PC, but create an execution file for Arm-based platforms, such as the UC-7112/7110.– 4 – – 5 – – 6 –/supportThe Americas: +1-714-528-6777 (toll-free: 1-888-669-2872)Europe: +49-89-3 70 03 99-0 Asia-Pacific: +886-2-8919-1230China: +86-21-5258-9955 (toll-free: 800-820-5036)2014 Moxa Inc.

imei第十五位计算
![imei第十五位计算](https://img.taocdn.com/s3/m/e69ec71b59fb770bf78a6529647d27284a73375e.png)
imei第十五位计算IMEI(International Mobile Equipment Identity)是指手机的国际移动设备识别码。
它由15位数字组成,用于唯一标识每台移动设备,包括手机和其他通信设备。
IMEI中的第15位被称为“检验位”,它主要用于验证IMEI的正确性。
在本文中,我们将详细解释第15位检验位的计算方法。
Luhn算法的计算步骤如下:1.从IMEI的倒数第二位开始,将每个数字乘以2,从而使得偶数位(从右数起的第2位、第4位等)变为奇数位。
2.如果乘以2的结果大于9,则将其减去93.将所有加上的数字相加。
4.将上一步骤的结果与下一个整十数比较。
a.如果结果等于下一个整十数,则检验位为0。
b.如果结果小于下一个整十数,则检验位为下一个整十数减去结果。
示例:1.从倒数第二位开始,将数字乘以2:1×2+5×2+3×2+3×2+2×2+0×2+4×2+1×2+9×2+5×2+4×2+0×2+ 4×2+9×2=87Luhn算法的目的是检测录入错误或转化错误,以及防止非法复制。
它对于验证IMEI的正确性非常有用,因为它可以捕获由人为或计算错误导致的输入错误。
需要注意的是,IMEI号码的计算方法可能会因各地的规定而有所不同。
此外,有些手机可能会使用MEID(Mobile Equipment Identifier),它的计算方法也会略有不同。
总结:IMEI号码由15位数字组成,其中第15位为检验位。
检验位的计算使用Luhn算法,它用于验证IMEI的正确性。
Luhn算法的计算步骤主要包括将偶数位乘以2,并将加上的数字相加。
通过将上一步骤的结果与下一个整十数进行比较,可以确定检验位的值。
苹果和三星的对比
![苹果和三星的对比](https://img.taocdn.com/s3/m/efa6eb21647d27284b735131.png)
从上表,我们可以清楚的看到,两者之间的差距,个人感觉IPAD2就像是放大版本的ITOUCH,毫无新意。
而三星P7500的硬件配置,个人感觉还是比较实在的,比较符合现在主流需求,无论是从硬件,系统来说,三星P7500要比IPAD2实用性要强很多。
在看看两者的外观设计,多图,多个角度细细的观察吧,我就不多说了,个人不太擅长分析这个外观,感觉两者掂在手里都是挺舒服的。
虽然三星P7500尺寸要比IPAD2要小,重量要轻,但是那个仅差0.3mm,重量相差35g,真的还感觉不到。
不过,既然是平板,我比较在意的还是屏幕分辨率,ipad2刚出来时候,感觉真的很不错,但是自从看了三星P7500之后,突然的发现IPAD2粗糙了很多。
三星P7500显示不仅细腻,色彩艳丽,还原真实,虽然不是三星引以为傲的super AMOled plus,但是三星的屏幕还是无可挑剔的,也不是苹果1024的普屏所能相比的。
而且三星P7500的屏幕是现在主流的宽屏16:10黄金比列设计,无论是网页,文档还是视频电影,视觉效果都是让人十分满意。
IPAD2是普通的4:3的设计,很多情况下,在浏览一些网页都会有一些问题,因为有些网站的通知,侧边栏快捷键都是放在了两边不会挡住中间的内容,但是在IPAD2中显示则会挡住中间的页面内容。
同时,IPAD2在欣赏宽屏电影时候,缺点尤为明显,因为9.7寸的显示屏比10.1小不了多少,但是,你会发现,ipad2显示的画面明显要比P7500少了一大截,就是因为IPAD2为了适应宽屏,不得不缩小视频的尺寸。
关于摄像头:三星P7500后置320W的像素虽然相比现在手机动辄500W 来说比较低了,但是这个300W加上LED闪光灯,自动对焦,那效果还是不错的,比之一些500W,800W来说,只是尺寸小了点,质量什么的并没有缩水,而且可以录制720P的高清视频。
前置200W的摄像头更是让人感到欣喜,效果真的很不错,想来现在3G了,还是30W的话就有点寒碜了。

三星有着自己庞大的数码掌上设备产品线,包括MID产品和此前发布的旗舰级智能平板电脑手机GaIaxy Tab P1000,GaIaxy TabP1000这款在海内外广受好评的机型,以7英寸超大屏幕,良好的抓握手感以及功能全面的Android应用,获得了苹果iPad最强竞争对手的“美誉”。
今天到来的这款GaIaxy TabP1010,实际上便是一款去掉3G功能的P1000,更加合适的价格和更加单一的用户诉求,会不会让它更加成功呢?和cross电脑、手机两大领域的GALAXY Tab前代产品不同,新的GALAXY Tab P1010是一款非常单纯的新产品,三星称之为智能平板电脑。
这款7英寸的产品和我们本期专题中其他的几款7英寸产品的类MID矩形设计有所不同,沿袭GALAXYTab P1000的外形设计的它类似一本非常适合拿在手上的“电子书”,正面纯黑色的设计是一块平板,而白色烤漆的背面则稍稍有些曲面,同时它的长宽比不大,所以整体拿在手上非常舒服(手较小的用户会觉得单手抓住稍有困难),总体来看,GALAXY Tab P1010具备了7英寸平板的一个最符合人体工学和平板使用习惯的外形特质。
一台随心所欲的平板试用GALAXY Tab P1010的最大感受体会就是随心所欲,可以拿着这台380g重的平板边走边用,也可以轻而易举将其放入裤袋或者背包之中,虽然它不具备手机通讯的功能,但是整机的各种按键设计和细节设计几乎都是把这款机型当做大屏幕通讯器在使用。
GALAXY Tab P1010的按键设计非常合理,用起来非常顺手正面下方是Android系统手机常见的力反馈触摸式控制键――对应菜单、主页、返回和搜索四大功能,而仅有的两个控制键(开关电源和音量调节按键)则均分布于机身一侧,无论采用哪种持握方式,都能很方便的控制屏幕。
GALAXY Tab P1010也配备了两个摄像头,虽然它不支持3G网络通话功能,不过这一设计依然很适合那些喜欢用后背摄像头拍摄微博照片,而后前置摄像头参与IM聊天软件的年轻用户。

Fuel consumption and CO2 emissions are specified for a vehicle variant and not for a single car. The applied standard test procedure enables comparison between different vehicle types and different manufacturers. In addition to the fuel efficiency of a car, driving behaviour as well as other non-technical factors play a role in determining a car's fuel consumption and CO2 emissions. CO2 is the main greenhouse gas responsible for global warming. Results in MPG also correspond to this European drive cycle and are stated in imperial gallons. The results may differ from fuel economy figures in other regions of the world due to the different drive cycles and regulations used in those markets.Note: The data information in this press release reflects preliminary specifications and was correct at the time of going to print.

The energy absorbedis determined from the subsequent rise of the pendulum.The satisfactory operation of a pendulum impact testing machine is dependent on factorswhich include the design, the foundation, the accuracy of construction of machinecomponents, the degree of wear, and the friction-free movement of the pendulum.During a test, all the absorbed energy indicated by the machine is attributed to thefracturing of the test piece. However, it is known that there are other mechanisms by whichsmall amounts of energy may be absorbed. It is suspected that items such as test piecesupports, the machine foundation and frame work, the pendulum and striker, ejection anddrag of the broken test piece cause some degree of energy absorption. This energy is notdetermined, as suitable methods and apparatus have not yet been developed for measuringenergy absorption by these individual items.L i c e n s e d t o C o l i n M .

Under certain circumstances, charpy machines meeting the requirements of ASTM E23 shall be deemed to comply with this Standard. Machines that have been calibrated to ASTM E23 may be used for testing with this Standard provided that the minimum specified energy is equal to or less than 100 joules. NOTE: Machines complying with this Standard and that have been calibrated to AS 1544.4 do not meet the requirements of ASTM E23. 4.2 Installation, calibration and maintenance The machine shall be installed and calibrated in accordance with Paragraphs A1 and A2 of Appendix A. It shall be recalibrated periodically, and when otherwise necessary, in accordance with Paragraph A2 of Appendix A. The machine should be maintained in satisfactory working order and condition in the intervals between successive recalibrations, in accordance with Paragraph A3 of Appendix A. 4.3 Test piece supports The test piece supports consist of two mutually perpendicular surfaces extending on each side of, and normal to, the plane of swing of the pendulum. Essentially, one of these divided surfaces supports the weight of the test piece and the other takes the reaction from the impact blow on the test piece. The corresponding parts of the divided surfaces are coplanar. The level of the supports shall be such that the longitudinal axis of a supported test piece is parallel within 2:1000 to the reference surface of the machine. The supports shall be of hardened steel. They shall be attached rigidly to the frame of the machine and shall satisfy the following conditions (see Figure 1): (a)Distance between supports ................................................................40 +0.5,−0 mm. (b) Radius of curvature......................................................................1.0 mm to 1.5 mm.L i c e n s e d t o C o l i n M .

(d) Angle of supports (see Note 2).........................................................90 ±0.1 degrees.NOTES:1 Ma chines ma nufa ctured with supports ha ving a n included a ngle of 78 degrees to80 degrees are acceptable.2 A relieving recess is provided at the junction of the two support surfaces.4.4 StrikerThe striker and its components shall comply with the following requirements:(a) The striker shall be of hardened steel.(b) The striker shall be attached rigidly to the pendulum and shall satisfy the followingconditions (see Figure 1):(i)Included angle of striker.............................................................30 ±1 degrees. (ii) Radius of curvature of striking edge.....................................2.0 mm to 2.5 mm. (iii) Maximum width of striker.....................................................................18 mm. NOTE: The ma ximum width requirement a pplies to a ny pa rt of the pendulum which pa sses between the supports for a dista nce of 7.5 mm from the centre of a supported sta ndard test piece in a direction pa ra llel to the striking edge. For rea sons outlined in Clause 4.5, widths less than 18 mm are desirable to ensure that adequate clearance can be maintained. (c) The striking edge shall be rounded with a smooth profile blending with the faces of the striker. (d) The plane of swing of the striking edge shall be within 0.5 mm of the centre of the gap between the supports. It shall also be vertical and normal to the supports. (e) When the striking edge is 10 mm away from the plane of the reaction surface of the supports, it shall be parallel within 0.03 mm in 10 mm to this plane. (f) When the striking edge makes contact with the test piece, the line of contact shall be perpendicular within 2 degrees to the longitudinal axis of the test piece. In addition, the striker shall be symmetrical about the plane of the swing of the striking edge. 4.5 Test piece clearance The requirements for the geometry of the test piece, test piece supports and striker at the instant of impact are such as to ensure clearance between the striker, the broken halves of the test piece and the supports, during the test. However, this clearance can be lost as a result of asymmetry of the striker or a change in alignment of the pendulum. The clearance between the supports and striker, or any adjacent part of the pendulum which passes between the supports, shall be not less than 10.5 mm. The broken test piece should be free to leave the machine with the minimum of interference, and should not rebound into the pendulum. Any end stop used for locating the test piece in the supports shall be retracted in order that it does not impede the movement of the test piece during the test. NOTE: Clea ra nce of 13 mm should be used to ensure the specimen does not interfere with the striker. 4.6 Centre of percussion The distance of the centre of percussion from the axis of rotation shall be equal to the length of the pendulum, ±1 percent.L i c e n s e d t o C o l i n M .

The length of the smallest scale mark should not be less than 2.5 mm. 4.9 Zero reading When the machine is operated normally but without a test piece in position, the reading indicated by the pointer is the zero reading. This reading shall not exceed ±0.5 percent of the nominal initial potential energy (see Paragraph A3.4 of Appendix A). 4.10 Friction losses Energy is absorbed by friction, including air resistance, bearing friction and friction of the pointer. The total losses by friction for one swing shall not exceed 0.5 percent of the initial potential energy (see Paragraph A3.5 of Appendix A).L i c e n s e d t o C o l i n M .

CONSTITUTION:Revolution detector 17 is installed on rotating shaft 16 driven by motor 13 through fly-wheel 14 and clutch 15, and output of detector 17, namely, number of revolution is compared with the set value through the comparator. In this case, contact point of comparator (for instance, it turns ON or OFF when the number of revolution is larger or smaller than the set value, respectively) 19 and the contact point of rotary cam 18 which is set so as to output the working signal at 20 deg. and 2 deg., respectively, are connected in series to form the circuit. Moreover, this circuit is formed so as to output the signal to solenoid valve 8 at 20 deg. when the number of revolution is smaller than the set value, and at 2 deg. when the number of revolution is larger than the set value. By the above mentioned constitution, the timing of working starting is set by the number of revolution of the press, and the cycle time is reduced to improve productivity.

附注
1、指标解释
固定资产投资(不含农户):是以货币形式表现的在一定时期内完成的建造和购置固定资产的工作量以及与此有关的费用的总称。
到位资金:是指固定资产投资单位在报告期内收到的,用于固定资产投资的各种货币资金,包括国家预算资金、国内贷款、利用外资、自筹资金和其他资金。
新开工项目:是指报告期内所有新开工的建设项目。
国有及国有控股:在企业的全部实收资本中,国有经济成分的出资人拥有的实收资本(股本)所占企业全部实收资本(股本)的比例大于50%的国有绝对控股。
在企业的全部实收资本中,国有经济成分的出资人拥有的实收资本(股本)所占比例虽未大于50%,但相对大于其他任何一方经济成分的出资人所占比例的国有相对控股;或者虽不大于其他经济成分,但根据协议规定拥有企业实际控制权的国有协议控股。
投资双方各占50%,且未明确由谁绝对控股的企业,若其中一方为国有经济成分的,一律按国有控股处理。
行政和事业单位的投资项目都属于国有控股。
登记注册类型:划分企业登记注册类型的依据是工商行政管理部门对企业登记注册的类型,按照国家统计局、国家工商行政管理总局联合印发《关于划分企业登记注册类型的规定》的通知(国统字〔2011〕86号)执行。
划分个体经营登记注册类型是依据国家统计局相关规定,按照国家统计局《关于“个体经营”登记注册类型分类及代码的通知》(国统办字〔1999〕2号)执行。
固定资产投资统计报表制度规定,基层统计单位均要填报登记注册类型。
登记注册类型由从事固定资产投资活动的企业或个体经营单位填报。
已在工商行政管理部门登记的,按登记注册类型填报,未登记的,按投资者的登记注册类型或有关文件的规定填报。
其中内资企业包括国有企业、集体企业、股份合作企业、联营企业、有限责任公司、股份有限公司、私营企业和其他企业。
港澳台商投资企业包括合资经营企业、合作经营企业、港澳台商独资经营企业、港澳台商投资股份有限公司和其他港澳台商投资企业。
外商投资企业包括中外合资经营企业、中外合作经营企业、外资企业、外商投资股份有限公司和其他外商投资企业。
2、统计范围
计划总投资 500万元以上的固定资产项目投资及所有房地产开发项目投资。
3、调查方法
固定资产投资统计报表按月进行全面调查(1月份数据免报)。
4、东、中、西部地区划分
东部地区包括北京、天津、河北、辽宁、上海、江苏、浙江、福建、山东、广东、海南11个省(市);中部地区包括山西、吉林、黑龙江、安徽、江西、河南、湖北、湖南8个省;西部地区包括内蒙古、广西、重庆、四川、贵州、云南、西藏、陕西、甘肃、青海、宁夏、新疆12个省(市、自治区)。
5、行业分类标准
2012年起,国家统计局执行新的国民经济行业分类标准(GB/T 4754-2011),具体请参见/tjsj/tjbz/hyflbz.
6、增长速度计算
固定资产投资增长速度为名义增速,由于固定资产投资价格指数按季进行计算,除1-3月、1-6月、1-9月、1-12月可计算固定资产投资实际增速外,其他月份只计算名义增速。
7、环比数据修订
根据季节调整模型自动修正程序,对2013年5月份以来的固定资产投资(不含农户)环比增速进行修订。
修订结果及2014年5月份环比数据如下:
年度月份环比增速(%)
2013年5月 1.32
6月 1.25 7月 1.37 8月 1.41 9月 1.26 10月 1.33 11月 1.35 12月 1.34
2014年1月 1.39 2月 1.28 3月 1.33 4月 1.34 5月 1.32。
