殲-20戰(zhàn)機模型、魯班機器人、垂直起降無人機，深圳市青少年活動中心正舉行一場免費科技展，歡迎大小朋友前往參觀。請看本報昨日的報道： A dazzling J-20 fighter jet model, a cool vertical take-off and landing (VTOL) air taxi, an endearing bionic pet, and a versatile robot barista — these cutting-edge exhibits are on display at an exhibition at the Shenzhen Youth Activity Center, located near Hongling Metro Station. 報道中的VTOL 全稱是vertical take-off and landing，即“垂直起飛、升空、降落”，是一種常用于直升機和戰(zhàn)斗機的技術(shù)。 VTOL technology means aircraft can theoretically take off and land almost anywhere, making them far more flexible. 垂直起降技術(shù)意味著飛機理論上幾乎可以在任何地方起飛降落，使其更加靈活。 |
