This book is based on a Ph.D. research that has been conducted at the Delft University of Technology in the Netherlands in collaboration with Dutch Electricity & Gas Distribution Network Operator, Stedin. This book was written as a result of wider interest that was shown by different industry groups on this topic after its public defence. This inspired the author to modify and publish a practical version of the research for a greater international audience. Therefore, the content of this book is intended for a double audience, on the one hand for those interested in the organisational and management aspects of maintenance.

题目描述 某人写了n封信,同时为每一封信写1个信封,共n个信封。如果把所有的信都装错了信封,问共有多少种?(这是组合数学中有名的错位问题。著名数学家伯努利(Bernoulli)曾最先考虑此题。后来,欧拉对此题产生了兴趣,称此题是“组合理论的一个妙题”,独立地解出了此题) 试编程求出完全装错情形的所有方式及其总量s。例如,输入n=3,即有3封信需要装入信封,完全装错的一种方式可以表示为312,表示第1封信装入第3个信封,第2封信装入第1个信封,第3封信装入第2个信封。对于n=3,完全装错的方式共有2种,分别是312和231. 输入 输入一个正整数n(2<=n<=6) 输出 输出完全装错情形的所有方式以及装错方式的总量s (每行输出5种方式,一行中的相邻两种方式之间用1个空格隔开。装错方式输出时,从小到大排列,见输出样例)。 样例输入 4 样例输出 2143 2341 2413 3142 3412 3421 4123 4312 4321 s=9

LED 线阵显示装置, 分为 LED 线性旋转显示主机和图文录入器两部分。主机用直流电机带动由红绿 LED 组成的线阵旋转, 同时线阵按照时序依次切换显示状态, 在固定区域利用视觉暂留效果形成 16×16 点阵, 用以显示图文;图文录入器用 HMI 触控屏作为人机交互界面, 实现图文录入和回放功能。主机与图文录入器通过无线通信方式进行信息交互,可由图文录入器控制主机切换不同工作任务, 以及改变线阵显示内容。The LED linear array display device is divided into two parts:the one is the main unit used to display content,and the other one is used to input the contents.The main unit is driven by a DC motor to rotate the linear array composed by red and green light emitting diodes.At the same time,the 16×16 dot matrix that switching the display state according to the time sequence on the main unit displays pictures and texts in the fixed area,by using the visual temporary effect.The HMI touch screen is used as human machine interface to realize the function that input and playback pictures and texts.The two parts of the device communicate with each other through wireless communication.The image and text input controller can control the main unit to switch different tasks and change the content of linear array displayed.

针对目前MSP430单片机实验装置较少、实验内容少,而且无MSP430高端产品的实验装置,研制了基于MSP430F5529单片机的综合实验装置,主要包括MSP430 Launch Pad和母板两部分。较传统的单片机实验装置增加了模拟电路的设置,设计的实验能够利用单片机的所有外设,可进行模块基础实验和综合实验两大类实验,非常适合自动化和电气信息类大学生学习使用。Concerning with the lack of experimental equipment and content based on MSP430,and especially,the experimental equipment of MSP430 senior products,an experimental equipment based on MSP430F5529 microcontroller is developed. It mainly consists of two parts: MSP430 Launch Pad and main board. Compared with traditional microcontroller experiment equipment,a few analog circuits were added. The experiment we set up takes advantage of all microcontroller peripherals. Students can do two kinds of experiments: module experiment and complex experiment.Therefore it fits university students in automation and electrical major very well.
