The influences of the calcination temperature and time , the concentration ratio of deionized distilled water to c - v _ 2o _ 5 and the agitation time on the synthesis of a - v _ 2o _ 5 were studied by orthogonal array design and the interactions between the parameters were considered . so the optimum experimental factors were obtained . lithium rechargeable battery positive electrodes based on these optimum conditions could lead to experimental cells with large discharge specific capacity and good cycling performance 用正交實(shí)驗(yàn)研究了煅燒溫度、煅燒時間、去離子水與晶態(tài)v _ 2o _ 5 ( c - v _ 2o _ 5 )的濃度比和陳化時間對合成a - v _ 2o _ 5的影響,討論了這些參數(shù)間的交互作用,并獲得了最優(yōu)試驗(yàn)參數(shù),以該最優(yōu)試驗(yàn)參數(shù)所制備的a - v _ 2o _ 5為可充鋰電池正極的實(shí)驗(yàn)電池,具有較大的放電比容量和較好的循環(huán)壽命。
Orthogonal arrays are essential in statistics and they are used in computer science arid cryptography - in statistics , they are primarily used in designing experiments , which simply means that they are immensely important in all areas of human investigation : for example , industry , agriculture , quality control and product improvement 正交表在統(tǒng)計(jì)上是必不可少的,而且被用于計(jì)算機(jī)科學(xué)和密碼學(xué)。正交表在統(tǒng)計(jì)上主要用于試驗(yàn)設(shè)計(jì),這意味著正交表在人類研究的各個領(lǐng)域都非常重要。例如工業(yè)、農(nóng)業(yè)、質(zhì)量控制和產(chǎn)品改進(jìn)。
However , when the size of image increases , the speed of this process drops obviously . in order to overcome this shortage , a new intelligent genetic algorithm ( iga ) , which applies an intelligent crossover ( ic ) based on orthogonal arrays ( oas ) , is proposed to search the optimal combination of the thresholding that is finally used to segment the image 但是當(dāng)圖像的尺寸增加的時候,該方法處理速度明顯下降,為了克服這一點(diǎn),本文采用基于正交數(shù)組的智能交叉( ic )的智能遺傳算法( iga )尋找最優(yōu)解,從而實(shí)現(xiàn)了圖像分割。
By using matrix theory and the theory of finite fields , we study the applications of projection matrix , permutation matrix , difference matrix , hadamard product , the generalized hadarnard product , kronecker product , kronecker sum and the generalized kronecker sum to construction of orthogonal arrays 本文利用矩陣?yán)碚摵陀邢抻蚶碚摚芯苛送队熬仃?、置換矩陣、差集矩陣、 hadamard積、廣義的hadamard積、 kronecker積, kronecker和、廣義的kronecker和在構(gòu)造正交表方面的應(yīng)用。
We also use the matter - elements concept , dependent function in extension theory etc . to do the process conditions with quantitativechange degree function optimization investigation , by the taguchi - method ’ s orthogonal array with least experiments to request processparmeter optimization to obtain various fields of applications 并運(yùn)用物元觀念、關(guān)聯(lián)函數(shù)等可拓理論來做制程條件質(zhì)變的最佳探討,藉著田口實(shí)驗(yàn)法中的直交表在最少實(shí)驗(yàn)次數(shù)下,求出最佳制程參數(shù),使其能獲得更廣泛的應(yīng)用。
