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And typical super heterodyne structure in rereiver part. this scheme benefited to reduce frequency error and phase error, and had the advantages of good dynamic range and selectivity, short exploitation cycle and small venture in the given performance demand, etc. this system implemented a six - layer hoard rf handset model together with baseband by using advanced eda tool veribest 2000
系統設計應用hd155131的gsm900 dcs1800雙頻解決方案，發射機部分主要採用offsetpll方案，該方案有利於減小系統的頻率誤差和相位誤差；接收機部分採用典型的超外差式結構，它具有優良的動態范圍和選擇性，在給定的性能要求下具有開發周期短、風險小等特點。The main work of this paper was as fellows : ( 1 ) generalized the development of pre - stressed steel structure in our nation and abroad, and pointed out the main problem in practice ; ( 2 ) presented the mechanism of pre - stressed steel structure and revealed its applicable range ; ( 3 ) established the optimization design model for pre - stressed steel structure, which accounts for constraints on stresses and displacements of structure ; ( 4 ) brought forward the optimization design method, which combined linear programming and the principle of full restriction, through which we can obtain the magnitude of each time pre - stress and the optimized sections of each members of structure ; ( 5 ) analyzed the best times of pre - stress and pointed out that 2 ~ 3 times is preferable ; ( 6 ) conducted optimization design on large - space steel roof, horizontal parallel steel truss with local cables, horizontal parallel steel truss with global cable, and ultra - static steel truss, the result of which indicated that the multiple pre - stress structure is very economic ; ( 7 ) compared different schemes of cable placement for horizontal parallel steel truss, and the results showed that the local cable only unloaded the second girders, but had no response on the first girders and stomach poles, while global cable could unload the second girders and the stomach poles outside of turning point of cable, thus proving that global cable is more economic than local - cable
本文的主要工作是：對國內外預應力鋼結構的發展歷史及現狀作了綜述和總結，指出當前預應力鋼結構工程實踐中存在的主要問題；闡述了預應力鋼結構的受力機理，並指出預應力鋼結構的適用范圍和特點；在考慮結構應力和變位約束的條件下，建立預應力鋼結構優化設計模型；提出多次預應力鋼結構優化設計方法和步驟，採用線性規劃和滿約束準則相結合的優化方法，可優化設計出施加的每一級預應力的大小，並得到結構各部分的優化截面；對多次預應力最佳的施加次數作了分析，並建議以2 3次為宜；為驗證文中理論和方法，分別對大跨多次預應力鋼屋架、局部布索的水平平行弦鋼桁架、整體布索的水平平行弦鋼桁架和局部布索的超靜定鋼桁架等算例進行了優化設計，經濟效益明顯；對水平平行弦鋼桁架的幾種施加預應力的方案進行比較，對于局部布索，預應力只對下弦起到卸載作用，對上弦和腹桿基本不起作用；而整體布索預應力除對下弦卸載外，對索折點以外部分腹桿也起到卸載作用，經濟效益好於局部布索。Super - large and large deposits, with medium and small deposits, make up a organic whole. the deposit clusters are our research objects. from the total distribution, controlling regularity of metallogenic factor association, and each other restricting functions between them can be studied
