, 2007 农村能源问题的实质是能源公平问题,向农村持续提供高品位的能源服务不仅是农村发展的需要,更是农村居民的基本需求和基本权力。改革开放以来,中国农村能源政策经历了从解决农村居民生活用能、到保障能源可持续发展、再到提高减缓和适应气候变化能力的目标演进。当前,政策的关键是按照公共服务均等化原则,促进经济发展过程中的能源公平,并在农村可再生能源的开发利用过程中保障农民的交易权力,提高农民的就业机会 ...

智能科学与技术学报, 2021 针对多光谱行人检测系统存在特征融合质量低、模型超参数多且锚框匹配算法复杂等问题，提出了一种基于差分特征注意力机制的无锚框多光谱行人检测算法。该算法首先采用差分特征感知融合方法挖掘多模态特征间的互补信息来优化通道特征；然后利用具有高效无锚框机制的CenterNet检测框架大大降低了模型计算复杂度，从而提升检测速度；最后引入差分特征注意力机制，改善特征融合质量，进一步提升检测精度。在KAIST、CVC14和FLIR这3个公开数据集上的实验结果表明，提出的算法和其他先进方法相比，能够同时有效提升检测精度和速度，

Functional Ecology, Volume 39, Issue 8, Page 1957-1971, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Many studies have focussed on niche differentiation at the population level to explain the coexistence of similar species. However, information on how individual‐level processes across multidimensional niches shape community dynamics and species coexistence, especially ...

Guangtongxin yanjiu, 2021 天线在通信系统中起着关键作用，但单一频段的天线已经无法满足如今的需求，因此多频天线的研究非常必要。文章提出了一种基于共面波导馈电的多频微带天线。该微带天线将刻蚀在基板导电表面的环形缝隙作为初始结构，之后在基板的不同位置加载电偶极子、超材料互补开口谐振环（CSRR）、交指电容加载环型谐振器（IDCLLR）及U形槽，从而实现微带天线的多频谐振。研究结果表明，天线能够同时在无线局域网（WLAN）波段（2.42~2.51 GHz）、全球微波互联网（WIMAX）波段（3.63~3.74、5.45~5.66 GHz）
