摘要：Owing to the excellent redox reversibility and structural diversity,polytriphenylamine(PTPAn)has been regarded as one of the promising cathode candidates for sodium-ion ***,it still suffers from the bulk aggregation and low operating capacity in practical *** by the in-situ polymerization,leaf-like PTPAn nanosheets are uniformly introduced on the surface of carbon nanofibers(CNFs)to form the free-standing CNF@PTPAn composite ***,the formation mechanism of the leaf-on-branch structure of CNF@PTPAn composites is systematically explored,confirming that the controlling of oxidation rate and growth degree plays crucial roles in tuning the morphology and active material content of the composite *** by the capacity-cutting analysis,the effective coupling between the active PTPAn and conductive CNFs can provide fast electron/ion-shuttling channels and deepen the electrochemical reaction *** 50mAg^(-1),the capacity of the optimized CNF@PTPAn composite can reach 105mAh g^(-1),with a stable rate capability of 78mAh g^(-1)even at 400mAg^(-1)after 500 cycles in a half *** detailed kinetic analysis confirms that the ion-storage behaviors in the lowvoltage region can be tailored for the improved capacitive contribution and diffusion ***,the flexible CNF-based full cell with CNF@PTPAn as the cathode and CNFs as the anode exhibits a high energy density of 60Wh kg^(-1)at 938Wkg^(-1).Based on this,the rational design is expected to provide more possibilities to obtain advanced freestanding electrode systems.

摘要：针对局部战争中对作战细节可视化的迫切需求,为实现全方位监视雷达视野中目标的表现姿态和运动情况,弥补传统雷达显示终端对三维空间信息表现不直观,画面单一等缺点,研究雷达信息的三维可视化显示,模拟真实的战场环境。提出利用OSG渲染引擎,以三维场景态势的构建和管理为核心,对目标模型动态加载、地面火力攻击显示以及空中目标实时变换、多样化视点等关键技术进行优化,设计和实现一种跟踪雷达三维场景显示系统。系统运行结果表明其具有良好的性能,能根据雷达信息完整地模拟出实时、逼真的三维场景显示效果。
