It is the bas of pa that using the spatial variable information of field to bear on decisions associated with agricultural production “精細(xì)農(nóng)業(yè)”技術(shù)思想的核心是根據(jù)農(nóng)田小區(qū)的實(shí)際需求實(shí)施定位調(diào)控的“處方農(nóng)作” 。
Assume that material constants exponential functions or power functions of spatial variable , the related bending fracture models are set , i . e . a series of boundary value problems of partial differential equations are established 再將材料常數(shù)依次設(shè)為空間變量的指數(shù)函數(shù)和冪函數(shù),建立了相應(yīng)的彎曲斷裂模型,即一系列相關(guān)的偏微分方程的邊值問題。
At present , most studies are linked to the semi - discrete scheme and the one - dimensional spatial variable . but there are very few studies about the full - discrete scheme and the higher dimensional spatial variable . furthermore , the former ca n ' t be extended directly to the latter 目前,大多數(shù)科研成果只限于對(duì)原方程是半離散和空間變量是一維的情況,對(duì)全離散格式和高維情況研究甚少,而后者并不是前者的平行推廣。
In section 4 , by making use of the fourier transformation for spatial variables and starting from the nonparaxial propagating equation of ultrashort pulsed beam in temporal frequency domain , the nonparaxial solution basing on the paraxial propagating solution was derived , which come to exact solution by iterative of the paraxial integral solution 在第四節(jié)里,通過采用空間變量的傅立葉變換和利用時(shí)間頻率域下的非傍軸傳輸方程,我們得出了超短脈沖光束傳輸?shù)姆前S的修正方法。
