This research work emphasizes the capability of delivering optically shaped targets through the interaction of nanosecond laser pulses with high-density gas-jet profiles,and explores proton acceleration in the near-critical density regime via magnetic vortex acceleration(MVA).Multiple blast waves(BWs)are generated by laser pulses that compress the gas-jet into near-critical steep gradient slabs of a few micrometres *** alternatives for delivering the laser pulses into the gas target are explored to efficiently control the characteristics of the density *** shock front collisions of the generated BWs are computationally studied by 3D magnetohydrodynamic *** efficiency of the proposed target shaping method for MVA is demonstrated for TW-class lasers by a particle-in-cell simulation.

黄土高原地质历史时期不同时间尺度上的植被演化规律与气候环境影响因素,以及植被替代性指标的解译等问题还值得进一步研究.本工作拟通过对灵台黄土剖面450ka以来黄土-古土壤样品总有机碳同位素(δ^(13)CTOC)和正构烷烃含量组合参数如C31/C27进行综合对比研究,从而为明晰这些问题提供一些新的讨论和证据.结果表明,450ka以来黄土高原中部C_3、C_4植物混生,以C_3植物为主;按生活型则草本、木本混生,以草本植物为主.在黄土高原气候较温暖湿润的mis9(S3时期),mis5(S1时期)阶段,可能出现过C_3木本植物的短暂增多,但总体上不存在大面积的森林.在阶段性变化上,黄土高原130ka以来草本植物总体增多,可能与区域性气候干旱化有关.在轨道尺度上,全新世较末次冰期,mis11(S4时期)较mis12(L5时期)C_3草本植物减少;在其他几个冰期旋回,间冰期较相应冰期C_3草本植物增多.植被替代性指标与建群种蒿属孢粉量的变化吻合较好,其变化可能与冰期旋回上水热配置有关.mis1(S0时期)与mis11(S4时期)气候相似,但全新世时期松属乔木的大量增多,暗示了人类活动和生态因子火活动的影响.

北美五大湖区的安大略湖北岸Don Valley Brickyard、Scarborough Bluffs、Bowmanville Bluffs剖面共同构成了北美东北部最长也是最厚的陆地第四纪沉积记录,较完整地记录了晚更新世劳伦泰德冰盖(the Laurentide ice Sheet)的演化.晚更新世劳伦泰德冰盖演化的重建有赖于这些经典剖面中重要沉积地层单元的准确年代学控制.传统的地层年代学主要是依靠少量14C年代,将主要的混杂堆积单元(diamicton)解释为气候变冷环境下的冰川扩张,并与指示全球冰量变化的深海氧同位素曲线一一比对建立起来的.这样建立起来的年代学存在很大的不确定性.20世纪80-90年代的少量热释光年代也不相吻合,最近的13个长石红外释光定年则只集中于Bowmanville Bluffs的一个分层,并未建立整个剖面的地层年代学,使这些经典沉积剖面的年代学一直没有得到系统的建立.应用石英光释光SAR-SGC法测试了Bow manville Bluffs剖面Glaciofluvial Sand单元的2个冰水沉积样品,年代结果分别为(41.6±3.8)ka、(48.1±4.4)ka,分析表明这一年代结果偏老,石英颗粒可能晒褪不完全.由于大测片无法识别晒褪不完全的颗粒,因此,测试更多的剖面序列的光释光年代并尝试采用粗颗粒小测片或单颗粒技术解决样品颗粒晒褪不完全的问题将是必要的.
