Core Viewpoint - The article highlights the festive preparations and operations of the lighting team in Beijing, specifically focusing on the decoration of Chang'an Avenue with traditional Chinese lanterns and decorations for the Spring Festival, showcasing the dedication and efforts of the "lamp keepers" who ensure the lights are maintained and operational during this important cultural celebration [1][10]. Group 1: Lighting Preparations - On February 6, the Spring Festival lighting decorations along Chang'an Avenue were fully set up, featuring 242 red lanterns and 862 Chinese knot lights, marking the beginning of the "Spring Festival mode" [1][3]. - The lighting team, known as "lamp keepers," is responsible for the installation and maintenance of these decorations, ensuring they shine brightly throughout the festival [3][10]. Group 2: Maintenance Operations - The maintenance team conducts inspections day and night, with each member responsible for checking the functionality and brightness of every lantern, ensuring a uniform display of red lights along the 13-kilometer stretch of Chang'an Avenue [4][8]. - The team utilizes specialized equipment, including temperature measuring devices and high-altitude work platforms, to safely perform maintenance tasks on the lanterns [6][10]. Group 3: Technological Integration - The lighting management system has been upgraded to include a new monitoring system capable of capturing real-time data from over 6,000 light sources, enhancing the team's ability to quickly identify and address any issues [10][11]. - Despite technological advancements, the experience and vigilance of the "lamp keepers" remain irreplaceable, as personal inspections are still necessary to ensure the quality of the lighting [11].

央视网消息：青藏高原，地球第三极。这里的冰川储存着亚洲1/3的淡水资源，却正经历着超常变暖的冲击。这座重要的"固体水库"正在 发生着怎样的变化？近年来，中国在青藏高原又开展了哪些科考工作？系列报道《跨越60年：雪域新画卷》我们跟随中国科研团队，探秘青藏 高原综合科考。 来古冰川地处青藏高原东部。数千万年间，板块碰撞挤压，群山不断隆起。眼前这条"没有路的路"布满碎石，平均坡度超过70度，到达冰 川就用了2个多小时。踏上冰面，眼前的一幕令人震撼。 邬光剑称："你看，现在这个地方反映的是冰川垮塌的一个过程，我们可以看到地下实际上是空的。这都是近年以来才发生的一些冰川的 快速变化，主要表现在消融上面，而且整个冰体的温度也是在升高的。" 冰温升高是影响冰川变化的重要因素。这次科研团队要从冰面向下钻探超过100米，测量冰川内部温度。 邬光剑称："这个孔打到了105米，现在是把钻和热水管往外提，然后我们就可以放测温仪了。" 冰川占地球陆地面积的10%左右，却储存着全球近70%的淡水资源。在全球气候超常变暖的背景下，青藏高原的冰川正在发生着哪些变 化？中国科研人员在世界三大冰川之一的来古冰川展开了一场探秘行动。 中国科学院青 ...
