We present a fast Galerkin spectral method to solve logarithmic singular equations on segments.The proposed method uses weighted first-kind Chebyshev polynomial
共生固氮结瘤是豆科植物与根瘤菌两者相互作用的结果。从根瘤菌接触根毛至形成成熟根瘤的过程,其实就是根瘤菌和宿主植物的有关基因的表达及其基因表达产物之间相互作用的过
我县属温带半干旱大陆性气候,年降水量较少,蒸发量大,干旱严重地限制了玉米产量的提高。经多次试验测得:1千克干沙土吸水达饱和时可吸水2.5升,而1千克泥炭吸水达饱和时较沙
In this note,we extend the algorithms Extra [13] and subgradient-push [10] to a new algorithm ExtraPush for consensus optimization with convex differentiable ob
In this paper,a novel class of exponential Fourier collocation methods (EFCMs) is presented for solving systems of first-order ordinary differential equations.T
本课题在已有研究基础上,选择具有一定代表性的五个品种、四个杂交组合,研究NaCl胁迫对菠菜发芽特性以及苗期生理生化特性的影响,以期为菠菜耐盐品种选育和盐碱地菠菜栽培提
