grading matrix造句
例句與造句
- Utilising dissolved gases analysis , a new insulation fault diagnosis method for power transformers is proposed . this method is based on the group grey relational grade analysis method . first , according to the fault type and grey reference sequence structure , some typical fault samples are divided into several sets of grey reference sequences . these sets are structured as one grey reference sequence group . secondly , according to a new calculation method of the grey relational coefficient , the individual relational coefficient and grade are computed . then according to the given calculation method for the group grey relation grade , the group grey relational grade is computed and the group grey relational grade matrix is structured . finally , according to the relational sequence , the insulation fault is identified for power transformers . the results of a large quantity of instant analyses show that the proposed method has higher diagnosis accuracy and reliability than the three - ratio method and the traditional grey relational method . it has good classified diagnosis ability and reliability
基于變壓器油中溶解氣體分析,提出了一種基于群灰色關(guān)聯(lián)度分析的變壓器絕緣故障診斷新方法.首先根據(jù)故障類(lèi)型與灰色參考序列構(gòu)造,選擇變壓器典型故障樣本構(gòu)造多組參考序列,這些參考序列組構(gòu)成一個(gè)灰色參考序列群.其次根據(jù)給出的新的關(guān)聯(lián)系數(shù)計(jì)算方法,計(jì)算個(gè)體關(guān)聯(lián)系數(shù)和關(guān)聯(lián)度.然后根據(jù)給出的群灰色關(guān)聯(lián)度計(jì)算方法,計(jì)算群灰色關(guān)聯(lián)度和構(gòu)造群灰色關(guān)聯(lián)度矩陣.最后根據(jù)關(guān)聯(lián)序識(shí)別變壓器絕緣故障診斷.通過(guò)大量變壓器絕緣故障診斷實(shí)例分析,所提方法診斷準(zhǔn)確性與可靠性?xún)?yōu)于三比值法和傳統(tǒng)的灰色關(guān)聯(lián)分析方法,具有較好的分類(lèi)診斷能力和可靠性 - It's difficult to find grading matrix in a sentence. 用grading matrix造句挺難的
