1甘肃河东玉米种植区春夏气象干旱时空变化特征及其与环流因子关系显示文摘甘肃河东玉米种植区属于旱作雨养农业区,农作物生长主要依靠自然降水来维持,春夏干旱是影响该区玉米生长发育的关键因素。利用河东地区13个气象站点1957—2012年气象资料,基于标准化降水蒸散指数从干旱趋势、周期、空间特征及其与环流因子关系方面探讨近56 a来河东玉米种植区春夏干旱演变特征。结果表明:近56 a河东玉米种植区春夏两季均呈干旱化趋势,并自20世纪90年代中期以后,干旱呈加重趋势。干旱变化共经历了3个气候阶段,20世纪80年代之前,春夏旱情较轻;80年代—90年代,夏旱较春旱严重;2000年以后,春旱较夏旱严重。干旱周期变化,春夏干旱周期分别为20 a和14 a,干旱周期性变化主要是受太阳黑子活动影响。春夏干旱发生频率在突变前后差异显著,低频区在突变后转为高频区,易旱区呈扩大状态。ENSO事件是影响该区春夏干旱发生的主要环流因子,尤其对夏旱影响最为显著。近20 a来ENSO事件增强是该区干旱事件不断加重的原因,ENSO暖事件爆发时,该区春夏趋于干旱,由湿向干转变;ENSO冷事件爆发,干旱则有所缓解,由干向湿转变。季定民 张勃 王东 马琼 张耀宗 赵一飞 Yousif Elnour Yagoub 2015自然资源学报2015,30,9:17
2POLYMER-CLAY NANOCOMPOSITES:CHEMICAL GRAFTING OF POLYSTYRENE ONTO CLOISITE 20A显示文摘准备聚苯乙烯(PS ) 的实验的一篇报道通过 grafting 的 nanocomposites 聚合物到 organophilic 上, montmorillonite 被报导。Cloisite 20A 与 vinyltrichlorosilane 被反应用乙烯基一半代替泥土的边氢氧根组。因为反应可以解放 HCl,与 H+ 离子阻止第四级的 alkylammonium 阳离子的交换面对钠 hydrogencarbonate 被执行。泥土的边上的仅仅 silanol 组与 vinyltrichlorosilane 反应。有乙烯基单体导致 PS 的化学 grafting 到 montmorillonite 表面上的苯乙烯的产品的激进的聚合。在聚合期间形成的 homopolymer 被 Soxhlet 抽取与 grafted organoclay 分开。聚合物的化学 grafting 被红外线的光谱学证实到 Cloisite 20A 上。准备 nanocomposite 材料和 grafted nano 粒子被 XRD 学习。Exfoliated nanocomposites 可以为 0.5 wt%1 wt% 泥土内容被获得。nanocomposites 被 thermogravimertic 分析(TGA ) 学习动态热分析(DTA ) 和动态机械分析(DMTA ) 。Yagoub Mansoori Khadijeh Roojaei Mohammad RezaZamanloo Gholamhassan Imanzadeh 2012Chinese Journal of Polymer Science2012,30,6:4
