飞行器弹道重建方法改进

基于飞行器的惯性测量数据,根据运动动方程,对弹道进行重建。为进一步限制误差的传播,利用遥测记录的时间步长较大的弹道数据,采用正向配点法和反向配点法进行弹道重建,并在重建弹道数据和遥测弹道数据的相关性的基础上,对正向配点法和反向配点法的计算结果进行加权平均。仿真结果表明,加权改进的方法精度更高。     

基于时间切片的通信计划合规性评估模型

针对体系作战背景下通信计划规划任务多线性和关系复杂的问题,提出了一种通信计划合规性评估模型。该模型通过构建计划时间切片,描述了多个通信保障任务主线在各阶段的全局关系视图,并定义了通信链路连接矩阵、电磁频谱三级规划和指控系统命名类量化,描述了通信计划的基本内容,同时定义了3类评估规则和3种评估运算法则,形成了完整的合规性评估体系。最后,通过实例分析验证了模型有效性,结果表明,评估模型能够较好地区分不同信息需求下的通信计划合理程度。     

Cell-type continuous electromagnetic radiation system generating millimeter waves for active denial system applications

The cell-type continuous electromagnetic radiation system is a demonstration device capable of generating high-power millimeter electromagnetic waves of a specific wavelength and observing their effects on living organisms. It irradiates a biological sample placed in a 30 × 30 × 50 cm³ cell with electromagnetic waves in the 3.15-mm-wavelength region (with an output of ≥1 W) and analyzes the temperature change of the sample. A vacuum electronic device-based coupled-cavity backward-wave oscillator converts the electron energy of the electron beam into radiofrequency (RF) energy and radiates it to the target through an antenna, increasing the temperature through the absorption of RF energy in the skin. The system causes pain and ultimately reduces combat power. A cell-type continuous electromagnetic radiation system consisting of four parts—an electromagnetic-wave generator, a high-voltage power supply, a test cell, and a system controller—generates an RF signal of ≥1 W in a continuous waveform at a 95-GHz center frequency, as well as a chemical solution with a dielectric constant similar to that of the skin of a living organism. An increase of 5 °C lasting approximately 10 s was confirmed through an experiment.     

黑腿星翅蝗（Calliptamusbarbarus）消化道组织结构观察

应用常规石蜡切片法，H·E染色，在光学显微镜下对黑腿星翅蝗（Calliptamusbarbarus）消化道组织结构进行了观察。结果表明，黑腿星翅蝗消化道壁由内向外的组织结构是：最内层为几丁质内膜或围食膜，然后依次为上皮层（肠壁细胞层）、基膜、环肌层、纵肌束和围膜。其中前肠和直肠的最内层具有非细胞结构的几丁质内膜，中肠则具有非细胞结构的围食膜，直肠部位具有6个直肠垫。消化道的组织学结构与蝗虫的一般结构相似。
