1. based on the data of analysis, using theories and methods of mathematical statistics, two of interception models by canopy of picea crassifolia are established as follows : the regression model on the relationship between penetration rainfall ( p, ) inside forest and total rainfall ( p ) outside of forest : pj = 0. 8245p - 1. 372 ( r = 0. 99 ) ; the model on the relationship between interception rate ( ir ) and rainfall : ir = - 10. 7111n ( p ). ( r = 0. 7524 ) the results show that penetration rainfall inside forest increases with total rainfall outside of forest in linearity, and to certain extent, penetration rainfall inside by canopy also increases with total rainfall outside ; the correlations of the interception rate to rainfall and intensity of rainfall are significant and the intercepted rate by canopy of picea crassifrlia is diminished with the increase of rainfall and rainfall intensity, and increase with the increase of canopy density
1在利用數理統計原理和方法對實測資料進行綜合分析的基礎上，建立了青海雲杉林林冠截留降水模型：林內透過雨量與降雨量回歸模型： p _ i = 0 . 8245p - 1 . 372 （ r = 0 . 99 ） ；林冠的截留率與降雨量的模型： i _ r = - 10 . 711ln （ p ） （ r = 0 . 7524 ） ；分析模型表明：林內透過雨量與降雨量呈良好的線性關系，在一定的降雨量范圍內，林內透過雨量隨降雨量的增加而增加；林冠截留率與降雨量、降雨強度之間也呈良好的關系，林冠截留率隨降雨量和降雨強度的增大而減小，隨郁閉度的增加而增大。The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
本文主要分析了三偏心蝶閥的結構，給出了三偏心的定義，推導出了蝶板截面的幾何方程及其性質，結果表明，沿蝶板厚度的平行截面輪廓線為標準的橢圓形，進而推導出了蝶板幾個主要截面的幾何參數（長軸、短軸）與三個偏心之間的函數關系；考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉，結合蝶板的啟閉扭矩，確立了三偏心蝶閥回轉中心的適宜區域。
