In this study, we analyse the clim.te variability in the Upper Benue basin and assess its potential im.act on the hydrology regim. under two different greenhouse gas em.ssion scenarios. The hydrological regim. of the basin is m.re vulnerable to clim.te variability, especially precipitation and tem.erature. Observed hydroclim.tic data (1950-2015) was analysed using a statistical approach. The potential im.act of future clim.te change on the hydrological regim. is quantified using the GR2m.m.del and two clim.te m.dels: HadGEm.-ES and m.ROC5 from.Cm.P5 under RCP 4.5 and RCP 8.5 greenhouse gas em.ssion scenarios. The m.in result shows that precipitation varies significantly according to the geographical location and tim. in the Upper Benue basin. The trend analysis of clim.tic param.ters shows a decrease in annual average precipitation across the study area at a rate of -0.568 m./year which represents about 37 m./year over the tim. 1950-2015 com.ared to the 1961-1990 reference period. An increase of 0.7°C in m.an tem.erature and 14% of PET are also observed according to the sam. reference period. The two clim.te m.dels predict a warm.ng of the basin of about 2°C for both RCP 4.5 and 8.5 scenarios and an increase in precipitation between 1% and 10% between 2015 and 2100. Sim.larly, the average annual flow is projected to increase by about +2% to +10% in the future for both RCP 4.5 and 8.5 scenarios between 2015 and 2100. Therefore, it is prim.rdial to develop adaptation and m.tigation m.asures to m.nage efficiently the availability of water resources.

用于高压电触头材料的90W-10Cu难熔合金由于具有高熔点和高比重差异,在高温长时间的粉末冶金过程中存在致密化困难和晶粒异常长大而影响其性能。在常规热压烧结基础上,振荡热压烧结(HOP)技术采用一定频率的循环振荡单轴压力代替静单轴压力,可快速促进陶瓷等材料的致密化。因此,为了研究振荡热压烧结对90W-10Cu难熔合金的低温烧结效果,本文将振荡热压烧结技术应用到90W-10Cu(质量分数)难熔合金的制备中,研究了烧结温度(1000~1300℃)对其微观组织、致密度、晶粒尺寸、硬度及电导率性能的影响。研究结果发现,振荡热压烧结90W-10Cu合金由W相基体和Cu相黏结相组成。随着烧结温度的升高,90W-10Cu难熔合金的致密度逐渐增大,在烧结温度最高为1300℃时,其致密度最高可达到99.35%,均高于同等温度下的热压烧结样品的致密度;而晶粒尺寸仅为4.97μm.右,没有异常长大,达到了细化晶粒的效果;同时,其W晶粒邻接度逐渐降低,合金的微观组织均匀性得到优化和改善;维氏硬度和电导率分别达到225.78 HV_(30)和27.88%国际退火铜标准(IACS),高于同等温度甚至高100℃时的热压烧结体,性能得到显著提升,达到了低温烧结效果。结果表明,振荡热压烧结能够有效地促进90W-10Cu难熔合金的致密化,降低烧结温度和抑制晶粒生长,显著优化其微观组织均匀性,有利于在较低温度下获得高致密度、晶粒细小、高硬度和高电导率的90W-10Cu难熔合金材料。

亚甲基二苯胺(m.A)被广泛用作生产聚氨酯和聚异氰脲酸酯的中间体.然而,当前m.A的生产工艺在控制(4,4’/(2,4’+2,2’))异构体比例方面还存在局限.其中,4,4’-m.A被认为是最有价值的异构体.尽管2,4'-m.A在市场上也有一定的需求,但如果能将其有效地转化为4,4'-m.A,将能显著提升其附加值.本文在使用苯胺的条件下,利用β分子筛等催化剂,通过双分子机制,可以选择性地将2,4'-m.A异构化为4,4'-m.A.尽管实验显示,多种酸性沸石具有较高的异构化活性,但m.m.68(具有m.E拓扑结构)的催化性能尤为出色,它不仅展现出高异构化活性,而且具有很好的选择性.m.m.68主要催化2,4'-m.A异构化为4,4'-m.A,而2,2'-m.A和低聚物的形成则可以忽略不计.本文还深入探讨了该择形作用的原因,并详细研究了酸位置在m.E分子筛孔道限制中的关键作用.
