  3. Based on tanner graph, the representation and construction of ldpc codes are addressed, and the two decoding algorithm for ldpc codes, i. e, bit - flipping algorithm and sum - product algorithm, are discussed. from two aspects - minimum distance and the failure of independence assumption, the impacts of cycles to the performance of ldpc codes are analyzed. 2

    基於tanner圖模型,詳細介紹了ldpc碼的表示和構造;介紹了ldpc碼的硬判決譯碼(比特翻轉演算法)和軟判決迭代譯碼(和積演算法) ;從最小距離和獨立性假設失效兩個方面分析了環的存在對ldpc碼譯碼性能的影響; 2
  4. Zhang liji ( material physics and chemistry ) directed by professor xie xiaoming this paper is intended to solve problems for those who are designing, using pbgas. failure mechanism, as well as cycles to failure of two groups of pbga samples ( with / without underfill ) for thermal cycling conditions in the range of - 40 ~ 125, were presented. the experiment shows that solder ball in the samples without underfill cracked after 500 times cycle, no crack was found in the underfilled samples even after 2700 cycles

    通過一系列的實驗,得到以下實驗結果: ?在本論文設定的溫度循環條件下,未充膠pbga樣品的熱疲勞品壽命在500周左右,充膠樣品的焊點壽命高於2700周; ?對于未充膠器件,中心距( dnp )是決定焊點應力、應變大小的最主要因素,裂紋總是從中心距較大處萌生並向中心處擴展; ?溫度循環的過程中焊盤附近焊料組織明顯粗化。
  5. Thus, for any given stress, the number of expected cycles to failure can be found.

    因此,對于任何一個給定的應力,就可以求出發出破壞的預定的循環次數。
  6. In practical application, it is subjected to local plastic strain cycles due to the power fluctuations during reactor operation ; extremely, this power fluctuations could lead fatigue failure

    在反應堆運行過程中,堆功率的波動和水冷卻介質的流動會導致燃料元件包殼局部承受反復的循環變形,極端情況下會導致疲勞失效。
