The mechanism of shock formation apparently changes, too, at these altitudes so that the scaling laws are no longer applicable.
在这个高度下，冲击形成的机制也有很明显的改变，所以递增公式也就不再适用了。
Noise measurements obtained over 30 years ago with scale models and their full-size prototypes are shown to verify the scaling laws proposed for predicting cavitation noise levels and spectra.
卅多年前，用比例模型及其全尺寸原型所获得的噪声测量，证实了为预报空泡噪声级和频谱所提出的尺度定律。
