  1. Regarding the serious smoke ejection of 75 diesel engine series, this paper points out that this problem could be solved by modifying certain parameters and employing gyrating regression design. the actual experiment on 375 diesel engine series shows that, after innovation, the maximum of smoke ejection of gyrating moment falls by 24. 2 percent, and then the rating is demarcated, the smoke ejection falls by 53. 8 percent

    本文針對75系列柴油機排煙嚴重的問題,通過改變噴油嘴及調整參數,利用多因素正旋轉回歸設計安排試驗,取得了較好效果.在375柴油機上的實驗結果明:進行優化匹調整后,最大扭矩點煙度下降24 . 2 ,標定工況時煙度下降53 . 8
  2. 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)製完全雙列雜組合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.具體現在產量性狀上,親本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)所組合沒有超過高親的.這明親本差異小、親源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.分析明了仍然存在嚴重的品質與產量的負,遺傳改良的難度較大
  3. Knowledge value chain describes new ways of envisioning the strategic process, which states that business strategies cannot be effectively shaped without a deep understanding of the knowledge capability interdependencies between core activities along the value chain as a core capability of innovation, new product development ( npd ) always makes great contribution to organizational performance. this dissertation proposes a framework of the link between km process capabilities and npd performance aiming at identifying the key facilitators of npd and enabling companies to launch their products into market more successfully than their competitors. attempts are made to measure km capabilities in terms of knowledge acquisition and dissemination and to use the results of empirical study for leveraging an organization against its competitors in the context of npd

  4. In the study, six different ecotype varieties of common wheat and f1 derived from 6 6 complete diallel crossing system were selected for the research on the characteristics and heterosis of spike differentiation. the results showed that heterosis existed in most key spike differentiation phases and varied with different ecotype varieties. heterosis of spike differentiation was positively correlated with heterosis of hybrid yield. finally, the author concluded that it was the best way to produce strong heterosis combination by selecting the mode of “ spring wheat winter wheat ” in huanghuai winter wheat region
