Acquisition of the fuse alarm digital variables : during idle , repeat acquired the 120 routes 48 analog data , process sample statistic for each rote acquired active - high 熔絲報警開關量信息的采集:在idle時候循環(huán)采集120路開入數(shù)據(jù),對各路采到的實時高電平次數(shù)進行樣本統(tǒng)計。
After explaining the both at hone and abroad relevant results of study , the whole paper . taking the approaches of sample statistics , comparison study , and many other approaches of prediction , has carried on the deep discussion on how to establish the relationship between quantity aid quality in the development of higher education , how to establish the scientific view of higher education in quality , how to construct the rational structure of higher education , and how to raise the efficiency in school management of higher educatin and realize that the scale , quality , structure , effectiveness of higher education develop harmoniously and allsidedly 本文就湖北省高等教育大眾化的規(guī)模、結構、質量和效益問題進行了全面系統(tǒng)的分析。全文采取了抽樣統(tǒng)計法、比較研究法、以及多種預測的研究方法,對國內外有關的研究結果進行闡述后,對如何確立高等教育發(fā)展中數(shù)量與質量的關系、如何確立科學的高等教育質量觀、如何構建合理的高等教育結構、以及如何提高高等教育辦學效益,實現(xiàn)高等教育規(guī)模、質量、結構、效益全面協(xié)調發(fā)展等問題,進行了深入的探討。
In this paper , taking one of the special processes - chromic acids anodizing for example , such administration methods as the key points control and the quality performance administration system for surface treatment process have been setup by process analysis and key points seeking . as for the complicacy of the quality control on metallurgical special processes and the huge statistic data , the quality information system of surface treatment have been established on the bases of computer database . this paper brings out the systematic evaluation way to setup reception test items by taking the reception test results as evaluation basis and sampling statistics as rules 本文以鉻酸陽極氧化表面處理工藝為研究對象,通過工藝技術分析、尋找關鍵特性、建立對關鍵特性的控制等工作,研究建立了表面處理工藝動態(tài)質量管理系統(tǒng);針對冶金特種工藝質量控制的復雜性及統(tǒng)計數(shù)據(jù)量大等特點,建立了以計算機數(shù)據(jù)庫管理為基礎的表面處理信息及處理系統(tǒng);為解決冶金特種工藝原材料入廠復驗任務重的困難,建立了以原材料入廠復驗的試驗結果為評價基礎,以抽樣統(tǒng)計方法為依據(jù)的原材料入廠復驗項目優(yōu)選系統(tǒng)等。
Being different from traditional neural network or nn , nn is based on traditional statistics , which provides conclusion only for the situation where sample size is tending to infinity , while svm is based on statistical learning theory or slt , which is a small - sample statistics and concerns mainly the statistic principles when sample are limited , especially the properties of learning procedure 支持向量機( svm )是九十年代中期發(fā)展起來的新的機器學習技術,與傳統(tǒng)的神經網絡( nn )技術不同, svm是以統(tǒng)計學習理論( slt )為基礎, nn是以傳統(tǒng)統(tǒng)計學理論為基礎。傳統(tǒng)統(tǒng)計學的前提條件是要有足夠多的樣本,而統(tǒng)計學習理論是著重研究小樣本條件下的統(tǒng)計規(guī)律和學習方法的,它為機器學習問題建立了一個很好的理論框架。
