随着无人机和智能弹药协同的兴起,进行高效的火力分配成为研究重点。传统的数学模型过于单一,不满足空对地合理分配需求;目前常用的元启发算法迭代较慢且容易陷入局部最优解。为了解决火力分配问题,提出了一种新的数学模型和改进离散狼群算法。模型兼顾摧毁目标价值最大化、己方损耗最小化、弹药协同打击;引入莱维飞行策略、汉明距离和编码段替换改进狼群算法中的智能行为。通过对比仿真,验证了新算法的高效性和可行性。

Throughout years,the two-step spin-coating process is the most common method to prepare organic lead halide perovskite ***,the short reaction time of dropping the solution at the second step means that PbI2 cannot be completely transformed into perovskite *** solve this problem,we report the introduction of glycine hydrochloride(GlyHCl)into the second step of the two-step spin-coating process to prepare a FA_(0.9)MA_(0.1)PbI_(3-x)%-GlyHCl perovskite material(namely FAMA-x%-GlyHCl,where FA=formamidinium,MA=methylammonium,and x%stands for the molar ratio of GlyHCl added in FA iodide/MA iodide(FAI/MAI)precursor solution).The Cl−ion in GlyHCl assists the formation ofα-phase perovskite,and the-COO−group coordinates with Pb2+cation in a bridging way,making up for the anion vacancy in perovskite lattice and resulting in high absorption *** perovskite solar cells(PSCs)based on FAMA-9%-GlyHCl achieve a long carrier lifetime(527.0 ns),a photoelectric conversion efficiency(PCE)of 19.40%and good thermal stability,maintaining 85.8%of the initial PCE after being continuously heated at 60℃for 500 *** study helps to solve the problem of incomplete reaction in the two-step spin-coating process and puts forward a new solution for preparing high coverage perovskite films with large grain size.

在道德需求持续攀升的今天,追求美德是去向至善的动力,是培育时代新人的基本条件。马克思主义道德观作为衡量道德的评判标准,是公民社会公德进一步发展的认识过程,是促进社会和谐发展的有力武器,是建设社会主义现代化强国的必然要求,更是公民个人品德建设的不二法宝。新时代公民道德建设面临新机遇新挑战,要从公民现实需求出发,自觉投身道德实践探索,夯实公民道德认知,提升公民道德水准,建构与新时代相适应的社会道德场景,使多媒体技术与公民道德建设有效衔接。

Metal oxide charge transport materials are preferable for realizing long-term stable and potentially low-cost perovskite solar cells(PSCs).However,due to some technical difficulties(e.g.,intricate fabrication protocols,high-temperature heating process,incompatible solvents,etc.),it is still challenging to achieve efficient and reliable all-metal-oxide-based ***,we developed efficient inverted PSCs(IPSCs)based on solution-processed nickel oxide(NiO_(x))and tin oxide(SnO_(2))nanoparticles,working as hole and electron transport materials respectively,enabling a fast and balanced charge transfer for photogenerated charge *** further understanding and optimizing the perovskite/metal oxide interfaces,we have realized an outstanding power conversion efficiency(PCE)of 23.5%(the bandgap of the perovskite is 1.62 eV),which is the highest efficiency among IPSCs based on all-metal-oxide charge transport *** to these stable metal oxides and improved interface properties,ambient stability(retaining 95%of initial PCE after 1 month),thermal stability(retaining 80%of initial PCE after 2 weeks)and light stability(retaining 90%of initial PCE after 1000 hours aging)of resultant devices are enhanced *** addition,owing to the low-temperature fabrication procedures of the entire device,we have obtained a PCE of over 21%for flexible IPSCs with enhanced operational stability.
