Consequently the academic base of strategic management accounting comes from the theory of strategic management, the theory of competitive advantage and farther application of the last word in management accounting including economic idea and the theory of management. basic methods of strategic management accounting not only comprise traditional analyse means, decision making means, control means, but also comprise new methods such as activity - based costing, target cost, value chain anahce, produce life cycle cost, the balanced scorecard ( economic value added ) in field of management accountingo this thesis introduces these new methods in three aspects in detail, those are programming in prophase, contro ] of proc ess and value of achievement
正因為如此，戰略管理會計的理論基礎不僅直接源於戰略管理理論，尤其是競爭優勢論，還體現了經濟思想、管理理論的最新成果在管理會計中的應用，其基本方法既包括傳統的分析方法、決策方法、控制方法，又包括了作業成本計算、目標成本計算、企業價值鏈分析、產品壽命周期成本計算、平衡計分卡（包括經濟增加值的計算）等管理會計新方法。 -
The first part of the paper is designing the testing project for grounding resistance and insulation resistance in a new way. using 16bits ad converter with programmable control amplifier replaced the way which used changing resistance to change measure range. lt is not only improved testing precision and develop the system expediently, but also reduced the area of the circuit boardwith the new way. in order to make the electric implement safety testing system have upstanding expansibility, the software and hardware of the system adopted the modularization design. adopted mcu atmegal28 as a master mcu which control mmi, realtime clock and communication with slaver mcu. atemga8 as the slaver mcu to realize testing function. so it is easy to add or reduce the testing project. the testing implement system has been developed successfully, and the comments for the system is that it has high precision, high expansibility and easy maintain. but considering the electric implement system should have intelligence and humanity abi lity. so this paper bring forward a scheme of electric equipment safety testing embedded system with speech control. after introduce the basic theory of speech recognition, the paper expatiate the characters of this system. the system is a noise conditon, not special people, small glossary, insulation word system. with these characters design the speech recognition as fellow. utilizing cross zero ratio and short energy to ensure jumping - off point and end point ; adopting mfcc as the character parameters of speech recognition ; the character parameters than be recognized by dtw. in order to ensure the credibility of this project, first realized by matlab in computer
在介紹了語音識別的基本原理后，闡述了本系統的特點：本系統是一個噪聲環境下非特定人、小詞匯量、孤立詞的語音識別系統。根據本系統的這些特點設計了如下語音識別方案：利用過零率和短時能量相結合的方式確定語音端點；採用mel頻率倒譜系數（ mfcc ）作為語音識別的特徵參數；得到的特徵參數最後通過動態時間規整（ dtw ）的模式識別方法進行識別。為了確保本系統實現方案的可靠性，首先通過計算機利用matlab軟體來模擬，在演算法模擬實現后又進一步增加環境的復雜性：加上較大的環境噪聲、突發性的噪聲等，再通過修改參數、修改參考模板、兩級識別等各種提高語音識別精度的方法來提廣東工業大學工學碩士學位論文高識別率。
