“发射角”常见的英文表达是 "launch angle" 或 "firing angle"。
launch angle:在航天、导弹发射、体育(如棒球、高尔夫球等运动中球的发射角度)等领域常用。例如:The launch angle of the rocket was carefully calculated to ensure it entered the correct orbit.(火箭的发射角经过精确计算,以确保其进入正确的轨道。 )
firing angle:多用于与火炮、枪械等武器发射相关的场景。例如:The soldiers adjusted the firing angle of the artillery to hit the target accurately.(士兵们调整了火炮的发射角,以准确击中目标。 )
