  1. Field germination, nodulation status and physical growth parameters of seedlings ( shoot and root length, vigor index, collar diameter, leaf number, fresh and dry weight of shoot and root and total dry biomass increment ) were recorded after three and six months of seed sowing

    播種的3和6月後，記錄幼苗大田發芽、分枝狀況和其他物理生長參數（枝條或根長、活力指數、莖直徑、葉片數、分枝或根鮮重和干重、總的生物量干重增長）等。
  2. Based on many references, a evaluating function is proposed with performance index of hall call waiting time ( hwt ), people number in a car, energy consuming. the statistic approximation algorithm for hwt is introduced, based on the analysis of elevator traffic state, the calculation of traveling distance and stop number is explained in detail in the thesis. according to the characteristics of the elevator, a group of elevator teaching signals are constructed, by which the weight coefficients are trained according to the widrow - hoff rule

    本文在借鑒了大量的文獻基礎上，提出以平均等候時間、轎廂人數、能源消耗為性能指標的評價函數；詳細介紹了乘客待梯時間hwt的統計近似演算法；基於對電梯交通狀況的分析，對停層次數和運行距離這兩個重要參數的計算進行了詳盡的介紹；依據電梯運行特性參數，構造一組電梯運行教師信號，並採用神經網路的widrow - hoff學習規則訓練權系數。
  3. Fifty nine accessions of soybean [ glycine max ( l. ) merr. ] of 301 ones from huanghuaihai and middle - lower changjiang valleys were tested at seedling stage in two years for their drought tolerance by using the mean membership index value averaged over those of plant height, leaf number, root dry weight, stem and leaf dry weight. 4 tolerant accessions ( rank 1 ) and 2 sensitive ones ( rank 5 ) were identified

    摘要從301份大豆品種中按根系類型選取黃淮海和長江中下游地區代表性材料59份，在苗期乾旱脅迫和非脅迫條件下對地上部和地下部性狀進行2年重復鑒定，發現材料間性狀隸屬函數值具有豐富遺傳變異，以株高、葉齡、根干重和莖葉干重隸屬函數的算術平均數為抗旱綜合指標，從中篩選出漢中八月黃、晉豆14 、科豐1號、圓黑豆等強耐旱型（ 1級）材料和臨河大粉青、寧海晚黃豆等乾旱敏感型（ 5級）材料。
  4. Using the f - ahp model algorithms that based on fuzzy number and interval arithmetic solve the multi - attributes and fuzzy problems of agricultural project appraisal. using entropy weight ranking of f - ahp is more efficiency. using a - cut and index of optimism x. estimate the uncertainty and preference of decision makers

    用基於模糊數、區間數運演算法則的f - ahp模型解決了農業項目投資評估的多屬性及模糊性問題；採用熵權使得排序更加科學；通過置信度與樂觀指數考慮了不確定性及決策者的風險態度。
  5. When the number of observation is small the order index for initial selection should be unit weighted rms ; the weight should be take into account ; the unit weighted rms correlated to gross error determination standard should adopt empirical value

    當觀測值較少時，初選之前觀測值的排序指標宜採用單位權中誤差進行；粗差的判別和復選之前的排序都應該考慮權重的影響；判別準則中的單位權中誤差應該採用先驗值。
