  1. 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。
  2. Higher - order statistics can deal with either colored noise, non - gaussian, nonlinearities or nonminimum phase, whereas second - order statistics can not. so these methods based higher - order statistics are wide applicable in signal process and system identifications. this paper describes the basic theory and methods based higher - order statistics in applicability of system identification and signal process, introduces and analyses the theoretical and algorithmic results of identifying non - gaussian arma process during recent years

    當基於2階統計量（如功率譜、相關函數）的經典辨識方法無法滿足有色噪聲、非高斯、非線性以及非最小相位系統的要求時，基於高階統計量方法越來越受到人們的重視，已經成為系統辨識和信號處理等領域的研究熱點之一。
  3. Similarity coefficient and genetic distances between two arbitrary individuals were caculated according to the data of experiments, the pedigree was constructed by two means ( they were upgma and parsimony ), and genetic diversity was discussedbased on selecting the best conditions of pcr with opg and opa primers from operon company, we obtained 163 bands using 24 random primers. in other words, 163 sites in crested ibis " genome were detected. the bands from 23 primers showed polymorphism. minimurn of polymorphic ratio was 0, maximum was 85. 71 %, and average was 48. 99 %. in the population which was composed by 37 individuals, most of genetic distances between two arbitrary individuals were less than 0. 1. the results showed that the degree of similarity among crested ibises was high while genetic diversity in the population was low accordingly

    我們在對operon公司opg系列和opa系列引物進行優化篩選的基礎上，用24條隨機引物共擴增出163條譜帶，即檢測了朱?基因組中的163個位點，其中23條引物的擴增結果具有多態性；譜帶的多態比率最小為0 ，最大為85 . 71 ，平均為48 . 99 ；在由37隻朱?組成的種群中，任意兩個個體之間的遺傳距離絕大多數在0 . 1以下。這些結果表明，目前朱?個體間的相似程度很高，種群的遺傳多樣性水平較低。
