Test results show that the nonlinearitydistortion of the testing method is smaller than 5?%.
测试结果表明：该检测方法的非线性可以控制在5%以内。

The distortion mainly comes from two mechanisms: the nonlinearity of the lattice potential and the interaction between the ultrasonic waves and dislocations.
波形畸变主要来自两个方面：固体中晶格原子之间作用力的非线性以及固体中位错和超声的非线性相互作用。

The distortion introduced by switching power amplifier is typically larger than in their liner counterparts due to intrinsic nonlinearity of switching converter.
