  1. There was double - logarithmic linear correlation significantly between specific weight metabolic rate and temperature in each of weight groups. temperature exponent ( b ) in the regression equation increased with weight increasing. the covariance analysis showed that the difference between the every two temperature exponents in the equations was significant

    ( 2 )特定體重代謝率隨溫度的上升而上升,各體重組的代謝率與溫度之間均呈顯著的雙對數直線相關;溫度指數( b )隨體重的增加呈現上升的趨勢,協方差分析表明,回歸方程的溫度指數( b )間差異顯著。
  2. In this paper, some characteristics of flow movement and sediment transport are analyzed by using the flume experiment data. the cross section of compound channel can be divided into four regions : the undisturbed region in main channel, the interactive region between channel and plain, the undisturbed region in flood plain and the boundary region. in the undisturbed regions, the distribution of longitudinal velocity along the depth has the feature of lograithmic. whereas, in the interactive region, the longitudinal velocity does not obey the logarithmic distribution law, but it can expressed as a revised logarithmic function by using a wake function. on the basis of the kinematic equation the velocity distribution of transverse velocity is obtained. in the boundary region, the longitudinal velocity obeys the law of parabolic distribution. furthermore, according to the simplified diffusion equation, the transverse distribution of sediment concentration in the interactive region is deduced. the analysis is in good agreement with the measured data

    本文根據漫灘水流的運動特點,將漫灘水流的復式斷面分為主槽平衡區、灘槽交互區、灘地平衡區及邊壁區等4個區,並給出了各區寬度的經驗公式.根據灘槽交互區垂線流速分佈的變化特點,提出了附加尾流函數的對數流速分佈公式.在簡化水流運動方程和泥沙擴散方程的基礎上,對灘槽交互區內垂線平均流速及含沙量沿橫向分佈進行了理論分析,提出了反映灘槽水流動量交換強度的橫向渦量粘性系數及橫向擴散系數的表達式,得到了漫灘水流垂線平均流速及含沙量沿橫向分佈的解析解,並與實測資料吻合較好
  3. Global existence and quenching for parabolic equation with logarithmic singularity

    含有對數奇異項的拋物方程解的整體存在性與猝滅性
  4. The linear regression models and the non - linear regression models are established respectively, which can be used in monitoring the grassland biomass based on the vegetation indices. finally, in order to establish the grassland biomass monitoring models with higher accuracy the different forms of the non - linear regression model were established respectively, including the quadric equation, the cubic equation, the logarithmic equation, and the exponential equation. the repeated tests indicated that the cubic equation is the best one in terms of the suitability of use in the study area

    建立遙感植被指數和草地生物量的一元線性回歸模型和非線性回歸模型,通過反復分析論證得出,非線性回歸模型相對於一元線性回歸模型與實測生物量更為符合;通過分析植被指數與實測生物量的不同非線性回歸模型的結果,表明三次方程y = - 18 . 626rvi ~ 3 + 220 . 317rvi ~ 2 - 648 . 271rvi + 691 . 093是最適用於監測研究區草地生物量的非線性模型。
