  1. But because of an indeterminate flexible structure with many degree of redundancy, its variant inner force under dead - loading, nonlinear behavior and the correlation between construction method and completed structure, especially incessant conversion of system in construction method, these must bring many complicated change to construction internal force and displacement. these main factors resulting in construction control analysis become more important in the design of cable - stayed bridge

    但由於它屬于高次超靜定的柔性結構，恆載內力狀態具有多樣性、結構狀態呈非線性、施工過程與成橋狀態具有相關性，特別是在施工階段結構體系的不斷轉換，必然給橋梁結構帶來較復雜的內力和位移變化，這些特點使得斜拉橋的施工控制分析成為突出的研究課題。
  2. The result of blastx shows that one orf is extracellular serine protease precursor gene ; 3 orfs function as regulatory genes ; 5 orfs are involved in secretion pathway ; 2 orfs are related to production of lps ; and the annotation functions of the other 3 orfs are not clearly related to extracellular protease prouduction. marker exchange method was used to study the relationship between the production of protease and the 3 orfs. a deletion mutant of xcc _ 4463 was constructed successfully

    Orf注釋表明，共中一個基因為胞外蛋白酶結構基因， 3個基因與合成調控有關， 5個與轉運分泌有關， 2個與lps合成有關，其餘3個orf的注釋功能與胞外蛋白酶的關系未見報道，為研究這3個orf與胞外蛋白酶產生的關系，採用同源雙交換orf缺失法進行了進一步驗證，成功地構建了xcc _ 4463缺失突變體，所得缺失突變體經檢測胞外蛋白酶減少，在寄主上致病性降低。
  3. Fault feature in stator current is extracted by singularity detection of signals with half - complex wavelet transform and it can be helpful to the real - time detection of motor fault. harmonics caused by the fault of motor is detected accurately with real - time harmonics cancellation method. steady state current and starting current in stator are analyzed with real - time harmonics cancellation method and the improved harmonic wavelet separately, after that the feature component of rotor fault can be detected successfully

    採用半復小波變換對電機定子電流進行奇異性檢測，提取故障突變信號，有助於電機故障的實時診斷；通過實時諧波消去法檢測定子故障引起的高次諧波電流；採用改進的實時諧波消去法精確提取電機穩態電流中的轉子斷條故障特徵分量；為了進一步提高轉子斷條故障診斷精度，利用改進的諧波小波對電機起動電流進行時頻分析，提取轉子斷條故障特徵。
  4. The results showed : ( 1 ) in the d - loop of mtdna genome from 18 individuals, there were only transition and transversion, were not insertion and deletion, and the frequency of transition was higher than transversion ; ( 2 ) and nucleotide diversity was 0. 0011, the sequence divergence values among haplotypes was 0. 005

    研究結果顯示： （ 1 ） 18隻大鴇的301bp - 330bpmtdna控制區序列的突變只有轉換和顛換，無插入和缺失，且轉換的頻率高於顛換； （ 2 ）核苷酸多態性只有0 . 0011 ，不同單元型間的序列差異值為0 . 5 。
