为解决反导拦截弹道快速规划问题,依据椭圆弹道理论与二体理论提出一种弹道导弹中段拦截弹道规划模型。在获取目标弹道某一时刻初始位置和速度状态信息基础上,利用椭圆弹道理论建立目标飞行位置与飞行时间的关系,实现对遭遇点位置信息的预测;根据拦截弹发射点位置以及预测遭遇点位置,利用Lambert方程在飞行时间的约束下解算拦截弹的状态信息,从而建立拦截弹的弹道规划模型;使用MATLAB软件仿真验证拦截弹规划模型的有效性。该模型为中段拦截弹道规划设计提供了一种思路和方法,并且在相应的约束条件下规划的拦截弹道在理论上能够满足中段反导拦截作战要求。

Enhancing the quality of junctions is crucial for optimizing carrier extraction and suppressing recombination in semiconductor devices. In recent years, metal halide perovskite has emerged as the most promising next-generation material for optoelectronic devices. However, the construction of high-quality perovskite junctions, as well as characterization and understanding of their carrier polarity and density,remains a challenge. In this study, using combined electrical and spectroscopic characterization techniques,we investigate the doping characteristics of perovskite films by remote molecules, which is corroborated by our theoretical simulations indicating Schottky defects consisting of double ions as effective charge *** a post-treatment process involving a combination of biammonium and monoammonium molecules, we create a surface layer of n-type low-dimensional perovskite. This surface layer forms a heterojunction with the underlying 3D perovskite film, resulting in a favorable doping profile that enhances carrier extraction. The fabricated device exhibits an outstanding open-circuit voltage(VOC) up to 1.34 V and achieves a certified efficiency of 19.31% for single-junction wide-bandgap（1.77 eV） perovskite solar cells, together with significantly enhanced operational stability, thanks to the improved separation of carriers. Furthermore, we demonstrate the potential of this wide-bandgap device by achieving a certified efficiency of 27.04% and a VOCof 2.12 V in a perovskite/perovskite tandem solar cell configuration.
