The non-linearity increases with the increase of the frequency change rate, which does not depend on the thickness of the resonant beam.

频率相对变化量与梁的厚度无关，增加频率的相对变化量也同时增加了输出信号的非线性度。

As the shear rate rises, the amplitude of pressure oscillation reduces, whereas the slide velocity, critical slide length and the frequency increase.

随剪切速率的增加，压力振荡的振幅减小，而滑移速率、临界外推滑移长度及振荡频率均有提高。

The results showed that on the yielding plateau, the internal friction did not change with the strain, but increased linearly with the increase of strain rate and varied inversely with frequency.

所得结果表明，在屈服平台上，范性形变过程中内耗基本不变，且其值随范性形变速率的增加和测量频率倒数的增加而线性增加。
