  1. Serious cross reation existed between v. albo - atrum and mv2, mv3, mv4. the other pathogen isolates v31 and v32 also had cross reactions, but the reaction was not serious. because limited number of pathogen isolates were selected, it could not prove that the selected immunogen was widely presentative, more pathogens isolates should be tested to verify the acquired hybridomas cells

    5株瘤細胞中沒有株具有種或屬的異性,其中mv2在棉花黃萎病菌若干菌系間的檢測表明其能夠區分不同的致病類型; mv1和mv4組合檢測的結果基本上能將棉花大麗輪枝菌鑒到種;黑白輪枝菌與mv2 , mv3 , mv4的叉反應比較強烈,其他菌株v3 , v32有個別的叉反應,但不強烈
  2. In order to select male nucleo - sterile new genotype, a tentative idea was put forward for the nucleo - male sterility to attach a tps ( thermo - photoperiod sensitivity ) and a selection strategy of combination of selection and identification, at the same time, the spring and summer sowing method were used to provide different environment conditions of appraising sterility and tps. the results indicated that ( 1 ) sterility could be appraised under the spring sowing environment and tps could be appraised under summer sowing environment. ( 2 ) under spring sowing environment, sterility could be selected, but not maintained. thereby, lines selected could only be selected as recorded selection method in the experiment. ( 3 ) and then, selection was carried out from spring sowing line selected into summer sowing in same line with tps to select plants. these plants through the intercrossing selection had been combined with sterility and tps. in this way, a new selection protocol for selection sterile line with tps was formed. it mainly involves the spring and summer sowing method, recorded selection method and the intercrossing selection method

    為了選育新類型玉米雄性核不育系,提出了為玉米核不育性添加溫光敏感性的設想和選擇與鑒相結合的策略,同時應用分期播種的方法為作物提供不同的生長和發育的環境條件,以鑒玉米雄穗的育性變化和對不同環境條件溫光的反應.研究結果表明,春播環境下可鑒和選擇玉米的不育性,夏播環境下可鑒和選擇其溫光敏感性.針對玉米核不育性難以找到保持系的性,結合兩種播期選擇兩種性狀.但春播環境下選擇的不育性群體難以通過選擇株來保持其不育性,為記錄性群體選擇.通過從春播入選的合不育性優良株系群體轉移到其對應的夏播溫光敏感性入選的同優良群體中進行優良株選擇,能逐漸使不育性和溫光敏感性相結合而選育出純合溫光敏不育系.這種新的選擇程序主要包括應用分期播種法、記錄性選擇法和春夏兩季叉式選擇法,使含有不育基因的可育株系逐步累積不育基因並增加了溫光敏感性而育成玉米溫光敏不育系
  3. As one of the main participators on the internet, the digital archives are in the center of the contradiction all along. moreover, because of the special status of archive information and all the national archives, this conflict tends towards complication : different copyright conditions of holdings, obscure attribution to the digitization right and the network transmission right, weak protection for the archive databases, immature of the copyright collective administration organization, high - degree flexibility of the " fair use " in the network, inconsistent of the terms in the relevant legislations or regulations, etc, all the difficult points turn up

    數字檔案館作為網路的參與主體之,也直處于這矛盾漩渦的中心,並且由於它所提供的內容涉及檔案這殊信息形式,以及檔案館作為國家文化事業位的地位,其著作權問題更趨復化:館藏檔案著作權狀態不、數字化權與網路傳播權歸屬不明、檔案數據庫的弱保護、著作權集體管理組織尚未成熟、網路合理使用范圍高度彈性化、相關法律法規限內容互有叉,等等,各種難點紛至沓來。
  4. Finally, genetic optimization research is summarized on several typical production scheduling problems. after expounding the general idea of genetic algorithm, the comparative advantages in contrast to the traditional algorithm, the basic characteristics of genetic algorithm and its theoretical base, the paper puts emphasis on the efficiency of genetic algorithm in the scheduling of flow shop, and puts forward an improving genetic algorithm : the ordinal genetic algorithm based on the heuristic rules. the new algorithm introduces into the initial group the solution of heuristic algorithm, and in the group structure adopts a strategy of first ordering according to the priority of the adaptive solution, and then defining a new way of choosing probability by segments, which provides more hybridizing opportunity for optimized individuals, and designs variation - control rule to prevent single population and partial optimal solution

    在論述了遺傳演算法的思想、與傳統搜索演算法的比較優勢、遺傳演算法的基本徵和遺傳演算法的理論基礎(包括模式理、隱含并行性、基因塊假設、欺騙問題和收斂性理)后,重點探討了遺傳演算法在flowshop調度問題中的潛力和有效性;結合啟發式規則,提出了個改進的遺傳演算法?基於啟發式規則的有序遺傳演算法,新演算法在初始種群中引入了啟發式演算法的解,在種群結構上採用了先按適應值優劣排序再分段確選擇概率的新策略,使優質個體有更多的機會,在變異中設計了變異控制規則,以防種群化,而陷入局部優化解。
