  1. Therefore, based on the key project ? esearch on some basic problems on quality control and source tracing in modern manufacture ? ( no. 59735120 ) sponsored by national natural science foundation, a deep research is made in this dissertation its branch subject ? the theory and technology of zero - waste control. the main work and achievements are as follows : 1. on the basis of the introduction of common quality control methods, some key problems about statistical quality control are elaborately discussed ; a method to decide the quality control line is developed ; a mathematical model based on the sampling plan of multi - variation of product quality is set up ; the process manufacturing condition of quality control chart is discriminated using the theory of fuzzy diagnosis

    為此，本文基於國家自然科學基金重點資助項目「現代製造質量控制、溯源若干基礎問題的研究」 （項目編號： 59375254 ） ，重點對其中的子課題? ?零廢品控制理論和技術進行了深入的研究。論文的主要工作和取得的成果如下： 1在介紹了常用質量控制方法的基礎上，對統計質量控制的幾個關鍵問題進行了詳盡的討論，提出了質量控制界限的確定方法，建立了基於產品質量多變異的抽樣方案的數學模型，利用模糊識別理論對質量控制圖工序加工狀況進行了判別。
  2. The chinese word wuli was first examined in literature of the warring states period. according to its wide use in ancient china, the word refers in general to the principle of all objects or the natural laws. in ancient times the meaning of wuli is similar to physics in the west. the translation of the english word physics was made some alterations in the introduction of western science during the ming and qing dynasties. from the 17th to the early 19th century, some chinese books on physics translated by protestant missionnaries were annotated and translated in japan. after the sino - japanese war reversed the flow of knowledge between china and japan. from the second half of the 19th century to the early years of the 20th century, the translation of the english word physics was defined early or late in japan and china. now the range and object of physical research are continually changing along with the rapid development of modern physics

    「物理」一詞，在中國古代最早見于戰國，此後在各種典籍中被廣泛使用，其含義泛指萬物之理與自然規律，這種含義與西方古代「物理」一詞的含義相近.明清時期西學東漸， 「物理」一詞的翻譯幾經變化.古代日本的科學在相當程度上受到中國的影響， 17世紀至19世紀上半葉來華傳教士譯述的物理書籍也在日本被注釋翻譯.甲午戰爭后，中日兩國之間科技交流的態勢發生了逆轉. 19世紀下半葉至20世紀初，日中兩國「物理」一詞的譯名先後確定.隨著現代物理學的迅速發展，物理學研究的范圍和對象又在不斷地變化
  3. Thanks to the support of the national natural science foundation of china under grand no. 50277036 for " the pulse electromagnetic fields and system - level em radiation of electric vehicles ", this thesis concentrated on the design of the variable voltage and variable frequency ( vvvf ) system and the development of a genetic algorithm for vector optimal design problems. the work includes mainly four parts : a brief introduction of the frequency - converter, the emc design of the vvvf system and the national standard of the electromagnetic interference of the vvvf system, the study of global search optimization algorithms, and an improved genetic algorithm called emigration genetic algorithm for multi - objective optimal problems

    在國家自然科學基金資助項目《電動汽車脈沖電磁場與系統級輻射的研究》的工作基礎上，本文對電動車電磁輻射關鍵部分? ?變頻調速系統的電磁兼容性設計以及在電磁兼容性設計中涉及到的電磁系統的多目標優化方法進行了系統的分析和研究，其核心內容包括：變頻器工作原理；變頻調速系統電磁兼容性設計及變頻調速系統電磁兼容標準；隨機類全局優化演算法研究；提出了一種改進的遺傳演算法命名為遷徙遺傳演算法。
