In this paper we introduce an image-based virtual exhibition system especially for clothing product. It can provide a powerful material substitution function, which is very useful for customization clothing-built. A novel color substitution algorithm and two texture morphing methods are designed to ensure realistic substitution result. To extend it to 3D, we need to do the model reconstruction based on photos. Thus we present an improved method for modeling human body. It deforms a generic model with shape details extracted from pictures to generate a new model. Our method begins with model image generation followed by silhouette extraction and segmentation. Then it builds a mapping between pixels inside every pair of silhouette segments in the model image and in the picture. Our mapping algorithm is based on a slice space representation that conforms to the natural features of human body.

在4 mg kg^(-1)的镉污染条件下,设置不同的外源硫和硅供应水平,对辽星1号和沈农315两个品种的水稻进行了土培实验,在分蘖期对辽星1号水稻进行了亚细胞分析,观察在不同条件下重金属镉的亚细胞分布;并在分蘖期测定植株茎叶部分的非蛋白巯基(NPT)含量,研究不同硫硅配比对水稻吸收分配重金属的机理。结果表明,沈农315号水稻叶当中的NPT含量高于辽星1号,外源硫可以提升两个品种水稻叶中的NPT含量,增强对重金属的耐性,同时增加镉在包括液泡在内的细胞可溶部分的分布;施硅可以强化细胞壁,随着施硅量的提升,根茎叶细胞壁中的镉分布均显著提升,并且根细胞壁中的提升幅度大于茎,说明施硅不仅可钝化土壤中的镉,并且在植物体内,加强根细胞壁对镉的固化是硅增强植物体重金属抗性的主要途径。

We calculate the three-dimensional potential energy surface(PES)for the fission of the compound nucleus^(236)U using covariant density functional theory with constraints on the axial quadrupole and octupole deformations(β_(2),β_(3))coexistence of the elongated and compact fission modes is predicted for comes shallow across a large range of quadrupole and octupole deformations for small scission line in the(β_(2),β_(3))plane extends to a shallow band,leading to fluctuations of several to ten MeV in the estimated total kinetic energies and of several to approximately ten nucleons in the fragment masses.

研究37℃条件下不同浓度纳米和非纳米氧化镁对单核细胞增生李斯特菌的抑制作用,以及低温(4和-18℃)对纳米氧化镁抑菌作用的影响,并通过扫描电子显微镜(SEM)观察了37℃条件下纳米氧化镁处理前后单核细胞增生李斯特菌细胞形态的变化。结果表明,37℃条件下,纳米氧化镁对单核细胞增生李斯特菌的生长具有明显的抑制作用,且抑菌效果随着纳米氧化镁浓度的增加而增大。在中性缓冲溶液中纳米氧化镁仍具有抑菌效果,但同浓度的非纳米氧化镁以及与纳米氧化镁同pH的碱性条件对单核细胞增生李斯特菌均无显著的抑制作用,因而推测纳米氧化镁的纳米材料特性是其抑菌的主要因素。在低温条件下,对照组单核细胞增生李斯特菌在4℃条件下能缓慢生长,-18℃条件下呈现下降趋势,添加纳米氧化镁后单核细胞增生李斯特菌的生长均受到显著抑制。37℃条件下的扫描电镜结果显示,1.5 mg/m L纳米氧化镁处理后单核细胞增生李斯特菌的菌体有所变长。
