　　For friends who love to travel and explore, having a clear and detailed map of China is indispensable. Maps not only help with itinerary planning, but also give you a deeper understanding of the culture and landscapes of each place. So, how to download the China map HD version of the large map tourist map?

井下无线传感节点能量有限,可利用能量收集技术将井下环境能量转换为电能为传感节点供电,从而延长无线传感节点生命周期.测试并分析了井下巷道弱光环境下光照强度,结果表明距光源1～2 m范围内,光照强度为50～170 Lux,符合非晶硅、钙钛矿等光电材料工作范围,因此将井下弱光能量转换为电能具有可行性.采用30 cm×40 cm非晶硅光伏电池板、BQ25505型电源管理芯片和锂电池设计了一种井下微能量收集装置,可将井下弱光能量转换为电能并存储.针对井下…City navigation map
