The “weightless“ condition of astronauts in orbit about the earth arises from just this cancellation of inertial and gravitational forces . 在圍繞地球運轉的軌道中,宇航員的“失重”狀態就是慣性力與引力相互抵消的結果。

It is in this sense that an astronaut orbiting the earth in a space capsule is said to be “weightless“ . 就在這種意義上,宇宙飛行員在宇宙密閉小艙里,環繞地球飛行時被說成是“失重”了。
