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.

題目描述 某人寫了n封信,同時(shí)為每一封信寫1個(gè)信封,共n個(gè)信封。如果把所有的信都裝錯(cuò)了信封,問共有多少種?(這是組合數(shù)學(xué)中有名的錯(cuò)位問題。著名數(shù)學(xué)家伯努利(Bernoulli)曾最先考慮此題。后來,歐拉對此題產(chǎn)生了興趣,稱此題是“組合理論的一個(gè)妙題”,獨(dú)立地解出了此題) 試編程求出完全裝錯(cuò)情形的所有方式及其總量s。例如,輸入n=3,即有3封信需要裝入信封,完全裝錯(cuò)的一種方式可以表示為312,表示第1封信裝入第3個(gè)信封,第2封信裝入第1個(gè)信封,第3封信裝入第2個(gè)信封。對于n=3,完全裝錯(cuò)的方式共有2種,分別是312和231. 輸入 輸入一個(gè)正整數(shù)n(2<=n<=6) 輸出 輸出完全裝錯(cuò)情形的所有方式以及裝錯(cuò)方式的總量s (每行輸出5種方式,一行中的相鄰兩種方式之間用1個(gè)空格隔開。裝錯(cuò)方式輸出時(shí),從小到大排列,見輸出樣例)。 樣例輸入 4 樣例輸出 2143 2341 2413 3142 3412 3421 4123 4312 4321 s=9

針對目前MSP430單片機(jī)實(shí)驗(yàn)裝置較少、實(shí)驗(yàn)內(nèi)容少,而且無MSP430高端產(chǎn)品的實(shí)驗(yàn)裝置,研制了基于MSP430F5529單片機(jī)的綜合實(shí)驗(yàn)裝置,主要包括MSP430 Launch Pad和母板兩部分。較傳統(tǒng)的單片機(jī)實(shí)驗(yàn)裝置增加了模擬電路的設(shè)置,設(shè)計(jì)的實(shí)驗(yàn)?zāi)軌蚶脝纹瑱C(jī)的所有外設(shè),可進(jìn)行模塊基礎(chǔ)實(shí)驗(yàn)和綜合實(shí)驗(yàn)兩大類實(shí)驗(yàn),非常適合自動(dòng)化和電氣信息類大學(xué)生學(xué)習(xí)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.
