Dear authors and readers,The idea of space tethers was first proposed to connect two or more orbital objects and has since been further developed into a variety of configurations,including innovative uses such as the E-sail,to meet the needs of on-orbit services,space exploration,and debris *** with other concepts or technologies,space tethers have the advantages of being low mass,compact,propellant-free,and easy to use,making them a major research *** merits are particularly appealing for the future use of micro/nanosatellites,which represent one of the main streams of future space missions.

科学合理地获取资源性收益对优化地方财力结构、提升资源配置效率具有重要意义。本文结合我国自然资源要素市场化改革,以矿业权改革为准自然实验,基于2015—2021年282个地级市的面板数据,使用双重差分模型实证分析了市场化改革对地方财力结构的优化效应。研究发现:矿业权改革对矿业权出让收益占比具有显著的正向影响,即矿业权改革能够优化地方财力结构,经过DID估计有效性检验和一系列稳健性检验后,该影响依然存在。异质性分析结果表明,矿业权改革对地方财力结构的优化效应在低纵向财政失衡度、高财政压力、高城投债风险和土地财政不可持续性的地区更大。机制分析结果表明,矿业权改革通过增加矿业权交易面积、提高矿业权交易价款,进而优化了地方财力结构。本文为有序增加资源性收益、优化地方财力结构提供了决策依据。

目前,建筑物中的暖通中央空调系统基本上是根据行业准则设置的,然而,多项研究表明,由于用户的偏好、姿态和需求各异,这种传统做法不太可能满足大多数用户的热量需求。为了更精准地满足用户热量需求,使得基于用户行为模式来针对性提高热舒适性成为可能。文中采用深度强化学习的方法实现智能化暖通空调智能送风策略,该策略能够根据环境和用户行为模式动态地确定最佳暖通空调设置(温度设置和送风设置),从而极大提高用户的热舒适度,同时,实验结果还表明该智能调控策略相比传统固定值控制策略具有一定的节能效果。

目的:探讨镜下椎间盘染色技术在腰椎内镜中的临床应用价值。方法:选取2021年1月—2023年2月拟行侧后路椎间孔镜手术治疗的腰椎间盘突出症(LDH)患者50例,按随机数字表法分为观察组与对照组,每组25例。观察组行镜下椎间盘染色,对照组不实施镜下椎间盘染色。对比两组围术期指标、疼痛程度、腰椎功能、并发症。结果:观察组手术时间短于对照组,术中髓核取出量多于对照组,有效透视次数少于对照组,差异均有统计学意义(P0.05)。结论:侧后路椎间孔镜手术中使用镜下椎间盘染色技术能够有效缩短手术时间,减少透视次数,提高髓核取出量,减轻患者疼痛程度,更好地改善腰椎功能。
