Lift-off is the moment a rocket or spacecraft leaves the ground and starts to rise. Mission control counts down to it; news clips freeze on that second, when the vehicle is no longer sitting on Earth. As a noun it often keeps the : lift-off. Planes more often take off; rockets lift off — though people mix the two, and you will hear both. We also stretch it: a plan, a product, or a career can ‘reach lift-off’ when it finally starts moving. That is space talk borrowed for ordinary life, a little dramatic on purpose.
升空；發射離地（火箭、太空船）
組成A noun made from the phrasal verb lift off (the rocket lifts off). That kind of shift — verb pair to thing-name — is called a deverbal.
