Methods are available for the measurement of absolute velocity constants but they are by no means easy to apply. 虽然某些方法对测定绝对速度常数是合用的，但不容易实施。
Under the same relative velocity, two vehicles with slower absolute velocities have more transient aerodynamic influence on each other during the overtaking process. 在相同的相对速度下，绝对速度较低的两辆车在超车过程中产生的瞬态气动影响更大。
