The plane elasticity theory of two-dimensional octagonal quasicrystals is developed in this paper. The plane elasticity problem of quasicrystals is reduced to
通过对长江口邻近海域表层沉积物中正构烷烃(n-alkanes)的含量进行调查,结果表明:沉积物中烷烃的含量范围介于17.3×10-9~2132.3×10-9之间,平均值821.2×10-9。靠近长江口附
By solving the extended Boltzmann equation and the electron number balance equation,we obtained the electron energy distribution functions(EEDFs)and the electro
The magnetic force images and surface topography images of sputtered Co/Au multilayer films in remnant state were measured by magnetic force microscopy. From th
A novel read-only super-resolution optical disc structure (substrate/mask layer/dielectric layer) is proposed in this paper. By using a Si thin film as the mask
We studied the temperature-dependent steady-state and time-resolved fluorescence properties of very small (1-2 nm) ZnO, CdO, and PbO amorphous nanoclusters prep
We calculate the light curve and phase-resolved spectra of Geminga in a three-dimensional pulsar magnetosphere model. The light curve of gamma-rays is consisten
The photorefractive effects of the as-grown and proton-implanted KNbO3 crystals were studied by two-wave mixing at 62.2 μW/cm2 illumination.At this pump power
The homogeneous balance method is extended to seek for B(a)cklund transformation, Lax pairs, non-local symmetries of variable coefficient KdV equation (VCKd VE)
随着水稻基因组测序的逐渐完成,基因库的不断完善,水稻也成为了研究单子叶植物和禾本科的模式生物。近年来,许多与抗旱性,花期,育性等农艺性状相关的重要基因被成功克隆。水稻的花期,也称抽穗期,是营养生长向生殖生长过渡的重要阶段。所以对调控水稻开花相关基因的克隆,对研究水稻花期有着深远的意义,有助于完善整个调控开花基因的体系,同时,对育种工作也有着遗传学的指导作用。本文通过过量表达技术(OverExpre
