2000年6月13日晚，我们的钠激光雷达在中国武汉（31°N, 114°E）上空观测到一个双钠层（DSL）结构。该DSL的独特之处在于，在80 ~ 105 km高度的正常钠层伴随在105 ~ 125 km高度的次级钠层，持续约2小时。介绍了激光雷达的观测结果以及附近的电离空探空仪和地磁设备的观测结果。虽然这种DSL形成的确切机制尚不清楚，但本文讨论了一些可能的解释和相应的观测证据。
A double sodium layer (DSL) structure was observed during the night of June 13, 2000 over Wuhan, China (31°N, 114°E) by our Na lidar. The unique feature of this DSL is that a normal sodium layer at altitudes of 80 ∼ 105 km was accompanied by a secondary sodium layer at altitudes of 105 ∼ 125 km for about 2 hours. The lidar observation result together with that obtained from the nearby ionosonde and geomagnetic equipments are presented. While the exact mechanism responsible for this DSL formation is still unclear, some possible explanations and corresponding observation evidences are discussed.
