  1. This study was conducted to examine the interrelationship of 10 seed vigor traits in 12 wheat genotypes through variance, co - variance and path coefficient analysis, to determine broad - sense heritability, and to estimate genetic advance under selection. the genotypes showed significant difference for all traits, except for percentage of normal seedling. genetic correlation between conversion efficiency of seed reserve, electrical conductivity with other traits were not significant, showed that selection for any of them might be possible without hampering any other traits. however path coefficient analysis indicated that conversion efficiency of seed reserve, seed reserve utilization ratio have strong direct effect in affecting seedling weight, and that mean germination time has significantly negatively correlated in affecting gi. moderate to high estimates of broad - sense heritability, genetic coefficient of variation and expected genetic advance were obtained for electrical conductivity, germination index, mean germination time, seed dry weigh, seedling dry weigh, seed reserve depletion ratio indicating the possibility for improving these traits

    本研究利用12個普通小麥品種對10個種子活力性狀的遺傳變異和相關研究,表明除正常幼苗百分率外,其餘種子活力性狀在品種間均存在顯著的差異.種子貯藏物質轉換效率、電導率兩個性狀間及與其它性狀均無顯著的遺傳相關,因此對他們的選擇不會影響到其它性狀.通徑分析表明幼苗干重主要取決于種子貯藏物質轉換效率、種子貯藏物質利用速率;發芽指數主要由平均發芽時間決定.電導率、發芽勢、幼苗干重、種子干重、發芽指數、種子貯藏物質消耗比率6個性狀表現中到高的遺傳力、遺傳變異系數和相對遺傳進展,指明通過遺傳育種手段改良這些性狀是可能的
  2. By constructing approximate functions and using prior estimate and conversion of variable, it is proved that the inverse problem has weak solution for given initial value, boundary value and the oil output

    通過變量和函數變換,作逼近函數和估計等方法,證明了對給定的初邊值和石油產量,此反問題存在弱解。
  3. Wood. estimate of the conversion volume of standing trees

  4. This paper considers decision - making process of rural - urban land conversion under irreversibility and uncertainty, then use the contingent valuation method ( cvm ) to estimate the non - market value of fannland at the urban fringe of hongshan district of wuhan. benefit - costs analysis technique has been adopted to evaluate the net profit of land conversion, based upon arrow and fisher ' s models on decision - making of resource develop / preservation, we build the model of decision - making on land conversions at the urban fringe. at last, we extend our concern and make exploration on the practical use of this theoretical model

    本文考慮了農地流轉過程中的不確定性和不可逆性,運用意願調查法估計農戶和市民對農地非市場價值的支付意願,通過嚴格的成本效益分析方法,借鑒arrow和fisher對資源開發轉用決策的開創性研究方法,建立了武漢市洪山區城市邊緣區農地城市流轉決策模型,並對模型在實踐中的應用進行了討論。
  5. Moreover, the data processing method of accelerated life test is used to solve the problem of the reliability data conversion under different operating status to liquid rocket engine. and the counter power law model is introduced as the relation model between the characteristic life and the combustion chamber pressure, the accelerated life equation of the constant stress accelerated life test for the weibull distribution is obtained, through the accelerated life equation, the reliability estimate of different combustion chamber pressure is calculated
