摘要：Sodium ions(Na+) and ether electrolyte coinserted graphite possesses a considerable volume expansion effect. However, the mechanism fails to clearly explain its stability. In response to this deficiency, the co-inserted reaction is proposed, which is affected by the Lorentz force of the applied electric field under the high-current condition. The Na^(+) ions are separated out, while the ethylene glycol dimethyl ether molecules remain between the graphite layers. This insight provides a reasonable explanation for the extraordinary stability of this material. In situ X-ray diffraction and density functional theory calculations confirm the separation and release of Na+. On the basis of this result, unmodified commercial graphite was stably cycled 6400 times at a current density of up to 10 A g^(-1), and the capacity retention rate was as high as 97.2%. The full battery assembled in the laboratory has a maximum output power of 14,846 W kg^(-1)and an output energy density of 103 W h kg^(-1)(relative to the weight of anodic and cathodic active materials). The new mechanism provides innovative ideas for the design of large-scale energy storage devices.

摘要：目的 将皮影艺术与现代游戏产品相结合,吸引更多年轻人对皮影艺术的关注,增强皮影艺术的传承性与活跃度,强化现代游戏产品设计中的文化内涵。方法 以游戏产品作为皮影艺术活态传承与流变再现的载体,通过用户调研对皮影游戏产品的用户需求与设计要素进行提取分析与转化修正。引入层次分析法(Analytic Hierarchy Process,AHP)构建决策目标方案模型,运用数学公式计算与评估各设计要素的权重系数,进而确定设计要素目标,得出皮影游戏产品的创新设计方案。最后通过七点量表与NPS(Net Promoter Score,净推荐值)评分来验证该设计方法的科学性与有效性。结果 AHP方法的运用,避免了用户需求提取时的主观片面性,明确了皮影游戏产品的设计要素与设计目标。结论 以桌面化小型皮影游戏产品设计为例,将AHP方法应用于传统皮影艺术与现代游戏产品相结合的设计中,验证了设计方法的适用性,为同类产品的设计研究提供了一定的参考。

摘要：结合某垂直起降无人机对螺旋桨的总体设计要求,分析了同时满足两个设计点的螺旋桨设计难点,完成了对所设计螺旋桨性能要求的验证,探究了两个设计点对螺旋桨设计性能的影响及影响因素,获得对设计的指导性结论.通过CFX软件进行悬停和巡航状态下的数值计算,并与其车载试验结果进行对比,结果表明:设计螺旋桨可满足设计要求,且数值模拟与车载试验结果基本吻合,误差不超过11%.将设计螺旋桨与单个设计点的旋翼或巡航螺旋桨进行对比,分析影响因素,发现两个设计点将会降低螺旋桨在每个单独设计点的工作性能,且通过减小起飞总质量和巡航速度、增加动力系统个数和功率来缩小设计点间差异可降低设计难度和性能损失.

摘要：镀膜玻璃可见光透射比是其光学特性的重要指标之一。本文提出一种玻璃透射比光电积分测量法。与传统光电积分法相比,该方法一次性解决了实验光源与CIE标准照明体、光探测器的光谱灵敏度与CIE光谱光视函数不匹配的问题。给出了该方法中设计校正滤色器光谱透射比的基本算式,并用相对误差最小对校正滤色器进行优化设计,得到了较为满意的结果。实验表明,该方法测量误差为±1%,小于国标标准要求的±2%。利用该方法所设计的测量装置结构简单,测量速度快,开发成本低,有可能应用于在线快速的质量检测。

摘要：提出了基于知识参照求隐藏元素的算法,隐藏元素的推理就是通过对立体图中含有隐藏边的点进行推理,参照其相邻边、过相邻点的边的方向和长度推理出可能的隐藏点集,然后根据重合性及连边规则对可能的隐藏点集进一步求解,得到隐藏元素的坐标信息和连边规则,图样的隐藏信息已得到恢复。三维推理就是用点的坐标信息和边的长度、角度信息推理每个点、边的深度。经过两步推理就实现了立体图的拓扑信息和深度信息的恢复。用一个原型系统进行验证,证明该算法对平面立体的隐藏元素推理十分有效。
