对额尔齐斯河支流哈巴河河谷林植物物种组成、多样性特征进行调查,并基于龄级结构评价了乔木物种的生存现状。结果表明:哈巴河河谷林共有维管植物30科70属86种,包括蕨类植物1科1属4种,被子植物29科69属82种。其中,国家二级重点保护野生植物2种,濒危种1种,渐危种1种,新疆特有种5种;菊科(Asteraceae)属数和种数均最多,为第1大科,其次是豆科(Fabaceae)和杨柳科(Salicaceae)。乔木优势种为垂枝桦(Betula pendula Roth.),灌木优势种为疏花蔷薇(Rosa laxa Retz.),草本优势种为草地早熟禾(Poa pratensis Linn.)。草本的Margalef丰富度指数、Shannon-Wiener指数、Simpson指数和Pielou均匀度指数总体大于灌木和乔木;草本的Margalef丰富度指数、Shannon-Wiener指数、Simpson指数和Pielou均匀度指数在海拔389~435 m间总体随海拔升高而升高,在海拔435~585 m间总体随海拔升高而降低。垂枝桦的幼苗〔Ⅰ级,胸径(DBH)≤5.0 cm〕、幼树(Ⅱ级,5.0 cm30.0 cm);苦杨(Populus laurifolia Ledeb.)和银白杨(Populus alba Linn.)的幼苗数量虽然较多,但各径级分布不均匀且壮树和老树较少;白柳(Salix alba Linn.)、黑杨(Populus nigra Linn.)、额河杨〔Populus×berolinensis ***(***)***〕、银灰杨〔Populus canescens(Ait.)Smith.〕和柔毛杨(Populus pilosa Rehd.)数量较少且各径级分布不均匀。总体上看,哈巴河河谷林植物资源丰富,草本物种丰富度最高,且分布相对均匀,对稳定哈巴河河谷林植物多样性有重要作用。哈巴河河谷林各乔木种群均存在一定程度的衰退风险,可从调整河流水量和放牧等方面加强哈巴河河谷林区域的生态保护,尤其是包含较多珍稀物种和新疆特有种的杨柳科。

随着对血液微流动过程的不断探索,红细胞在微通道中的运动微观特性备受关注,利用流体力学特性的低损伤手段调控细胞体积并完成跨膜传药也逐渐成为研究热点.为了分析红细胞在微通道中的传质和力学特性及其影响因素,采用浸入式边界法研究细胞穿越狭窄通道的整个运动过程,并考虑细胞膜表面透水传质效应,完成细胞跨膜传质过程的数值建模,实现对狭窄通道中红细胞跨膜传质过程微观的传质特性数值分析.研究表明,细胞在挤入、排出狭缝的运动过程中,体积先损失、后恢复,在这个过程中,细胞头部和尾部以向外的渗透流出为主,中间部位则以向内的渗透流入为主.文章的研究进一步表明,狭缝挤压过程中的体积净变化是由向内和向外渗透速度的大小差异引起的,而与向内和向外渗透的膜面积差异并无明显关系.对体积变化的影响因素探究后发现,更狭窄的通道和更大的入口出口角均会引起细胞发生更多的体积损失和体积恢复,且出口角的变化会引起细胞体积恢复后所达到的体积稳定值:在固定入口角时,狭缝出口角越大,细胞离开狭缝后的稳定体积越小;细胞的硬度越大、细胞膜通透性(渗透系数)越大,细胞在狭缝中运动过程中的体积损失和体积恢复程度越高.
