sdq 解釋
長處和困難問卷
  1. In this paper, we study two kinds of error - correcting codes. one kind is cyclic code over finite chain rings, and the other is sdq ( b ) code over finite fields

    本文研究了有限鏈環上的循環碼和有限域上的sd _ q （ b ）碼這兩類糾錯碼。
  2. One of reasons is that there is no topology on closed sets which guarantees the compactness of the minimising sequences and the lower semiconti - nuity of the sdq - 1

    原因之一在於不存在關于閉集的拓撲能夠保證極小化序列的緊性和s _ d ~ （ q - 1 ）的下半連續性。
  3. At present study, by using the sdq ii, the self - concept of secondary schools in guangzhou, china were surveyed

    本研究的目的主要是探討中學生自我概念的群體差異、學業自我概念與學業成就之間的關系。
  4. Quantization reseach depends on sdq and mht questionnaires, which analyses the development of primary students " self - concept and psychological health. the results are shown as following : 1

    量化研究採取了問卷調查法，以sdq和mht問卷為調查工具，分類分析討論了現實條件下小學生自我概念及心理健康的發展情況。
  5. Since 1980 ' s, the research of self - concept has made quiet great progress due to the view of self - concept as a multidimensional and hierarchical structure, the widely use of the sdq ( self description questionnaire ) and the improvement of the statistics

    由於shavelson （提出了多維度層次模型）的開拓性工作， marsh編制的自我描述問卷（簡稱sdq ）的廣泛使用，以及統計技術的發展，使自我概念的研究獲得了新的進展。
  6. Sdq ( b ) codes over finite fields are byte - organized and they can correct any single error and detect all double - ajacent errors in the same byte. for sdq ( b ) codes satisfying q > 3, b > 2 over finite field fq, we give a lower bound than the pairs bound

    有限域上的sd _ q （ b ）碼是一類按位元組組織的，能糾正發生的所有單個錯誤，同時能檢測發生在同一位元組內的兩個相鄰錯誤的糾錯碼；我們對有限域f _ q上sd _ q （ b ）碼的線對界在q 3 ， b 2時給出了一個改進界。
