  3. Twenty f1 combinations crossed among 5 varieties and strains different in fiber properties according to complete diallel crossing design were used to evaluate the heterosis and gene action of boll weight and lint percentage in high quality fiber property varieties in upland cotton in 1998 1999 for two year successively at nanjing. it was indicated that there existed small interactions with the environmental factors without maternal effects and the additive gene effect was in chief, attaining to 51. 2 % and 65. 4 % respectively for boll weight and lint percentage. the dominant effect was also in higher rate, 32. 6 % and 16. 8 % respectively. the population mean heterosis of boll weight and lint percentage over the mid - parental mean were relatively prominent 13. 3 % and 3. 5 % respectively in extreme significance. however, boll weight showed no significantly surpassing parental f1 heterosis over the better parent based on population mean ( 2. 0 % ) ; while the lint percentage expressed significant negative heterosis value ( - 2. 1 % ). the gene actions were in conformity with the heterosis expression. it was shown clearly that the f1 combinations crossed between parents with similar performances had relatively high dominant effects and significant positive f1 surpassing parental heterosis ( f1 heterosis over the better parent ) ; while no f1 combination crossed between the parents with prominent mutual difference surpassed the higher parent in yield components, which indicated that among those parents with less difference and close relationships, there still existed sufficient genetic variation or certain mechanism for creating variation and achieving greater advances in breeding. correlation analyses also indicated that there still existed severely undesirable negative correlation between yield and fiber properties as well as the difficulties for their simultaneous improvements

    利用5個具有不同纖維品質性狀的品種（系）配製完全雙列雜交組合20個，通過親本和f1的2年隨機區組試驗發現產量性狀的鈴重和衣分與環境的互作效應小，不存在母體效應，並以加性遺傳效應為主，分別占表型方差的51 . 2 %和65 . 4 % ;顯性遺傳效應所佔的比率也較高，分別為32 . 6 %和16 . 8 % .鈴重和衣分的群體平均優勢較大，分別為13 . 3 %和3 . 5 % ，達到了極顯著;鈴重的超親優勢為2 . 0 % ，不顯著;衣分為顯著的負值（ - 2 . 1 % ） .遺傳分析與雜種優勢結果一致.具體表現在產量性狀上，親本相當配製的組合雜合顯性較高，其超親優勢正向顯著，而極值親本（差異較大）所配組合沒有超過高親的.這表明親本差異小、親源關系較近的親本中仍然存在足夠的遺傳變異或某種機制以創造變異使育種取得更大的進展.相關分析表明了仍然存在嚴重的品質與產量的負相關，遺傳改良的難度較大
  4. It requires compatible part and support materials, subject to the constraints of the deposition and removal processes. the constraints on part and sacrificial support materials were identified and a compatible material combination was developed : unsaturated polyester and wax. some other investigation is conduct, such as the effect of additive on the cure of polyester, the effect of the filling on strength and shrinkage. the part strength is determined both by the bulk material properties of the part materials and by their interlayer bonding

    從分析材料的選擇機制出發，本文經過大量的實驗分析，選擇了一組較好的材料組合：不飽和聚酯樹脂與蠟的組合，通過實驗分析了引發劑、促進劑對其固化過程的影響以及填料對其強度和收縮率的影響，通過測試，分析了材料的粘接強度，為工藝實現提供重要依據。
  5. It can be concluded after analysis that the speech distortion and the residual noise can be approximately regarded as multiplicative noise and additive noise, respectively. thus, we use a parallel model combination ( pmc ) algorithm, which is deployed in model space, to adapt the parameters of speech models to compensate the residual noise, or we use a cepstral mean normalization ( cmn ) algorithm in feature space to compensate both the speech distortion and the residual noise

    分析表明，語音失真和剩餘噪聲可近似看作乘性噪聲和加性噪聲，因此可在模型空間利用并行模型合併（ pmc ）演算法通過調整模型參數對剩餘噪聲進行補償，或者在特徵空間利用倒譜均值歸一化（ cmn ）演算法對語音失真和剩餘噪聲同時進行補償。
