空间伸展结构是一种最基本的可展开折叠单元,广泛应用于大型展开天线、太阳帆板以及空间机械臂等航天领域,针对此类结构服役状态的智能辨识对于目前开展高轨深空探测研究具有重要意义。为此,提出一种基于准分布式光纤传感器的空间伸展结构变形与振动实时监测技术。借助***/Nastran有限元分析方法,数值模拟得到碳纤维复合材料柔性空间伸展结构在不同载荷作用下的应变、位移响应规律以及振动模态特征。分别研究了基于曲率和弧长信息曲线重构的结构变形反演算法,光纤光栅中心波长偏移量与振动特征关系解析模型,计算得到空间伸展结构沿展开方向不同位置的坐标信息。在此基础上,通过在柔性复合材料伸展结构展向布设离散光纤光栅传感器,实时采集应变分布与变化信息,进而推导相应位置曲率特征,实现不同加载模式下的伸展结构形态重构,变形反演相对误差约为2.5%。此外,借助准分布式光纤传感器不仅可以得到伸展结构对应的变形实时响应曲线,同时还能够获取其前三阶固有模态和振型特征,所测频率与仿真结果吻合度较好,平均误差约为0.67%。研究结果表明,所提方法具有非视觉测量、实时性好以及多种功能复用等优点,能够为未来及时准确获取空间伸展结构姿态,实现空间形态自适应调节与在轨振动主动控制提供有力保障。

大脑的发育、生理功能和病理与神经元和不同类型的神经胶质细胞(如星形胶质细胞、小胶质细胞、少突胶质细胞和少突胶质细胞的前体细胞等)之间的相互作用密切相关。研究脑功能及其功能障碍,除了神经元之外,还需要对不同类型的神经胶质细胞进行研究。近年来,多项技术突破使“神经胶质科学家”能够解决新的具有挑战性的生物学问题。这些技术发展使得以中/高含量工作流研究特定细胞类型的作用成为可能,并在保存完好的环境中对其相互作用进行精细的分析。本综述阐明了几种可能揭示神经胶质细胞在特定脑功能或疾病中作用的尖端实验方法。这些实验方法包括高级细胞培养,诱导多能干细胞(iPSC)衍生的人神经胶质细胞,病毒载体,原位胶质细胞成像,光学遗传学和化学遗传学方法,以及高内涵分子分析。本文还阐述了某些技术的临床转化,通过特定的脑成像方法以监控患者的神经胶质细胞。本文亦讨论了每种技术的优点,缺陷和未来发展,并提供了选定的示例以说明现在如何可以解决特定的“胶质生物学”问题。
