歼-20战机模型、鲁班机器人、垂直起降无人机，深圳市青少年活动中心正举行一场免费科技展，欢迎大小朋友前往参观。请看本报昨日的报道：

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.

报道中的VTOL 全称是vertical take-off and landing，即“垂直起飞、升空、降落”，是一种常用于直升机和战斗机的技术。

VTOL technology means aircraft can theoretically take off and land almost anywhere, making them far more flexible.

垂直起降技术意味着飞机理论上几乎可以在任何地方起飞降落，使其更加灵活。
