It is the bas of pa that using the spatial variable information of field to bear on decisions associated with agricultural production “精细农业”技术思想的核心是根据农田小区的实际需求实施定位调控的“处方农作” 。
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 再将材料常数依次设为空间变量的指数函数和幂函数,建立了相应的弯曲断裂模型,即一系列相关的偏微分方程的边值问题。
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,大多数科研成果只限于对原方程是半离散和空间变量是一维的情况,对全离散格式和高维情况研究甚少,而后者并不是前者的平行推广。
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 在第四节里,通过采用空间变量的傅立叶变换和利用时间频率域下的非傍轴传输方程,我们得出了超短脉冲光束传输的非傍轴的修正方法。
