velocity fluctuation的用法和樣例：
例句
- The application of a pressure difference across an injector does not cause an immediate velocity response of the liquid propellant.
經過噴注器的壓降發生變化時並不馬上引起液體推進劑速度變化。 - The correction of an excessive velocity variation is not as serious a problem as the correction of excessive angular variation.
對速度變化過大時的修正問題不象對偏角變化過大時的修正那樣重要。
