功率放大器两个基本要求：一是输出信号变化能够与输入信号的变化相一致，即：系统失真小：二是整个功率放大器的损耗低，即：系统效率高。

The requirements are: the change of output signal is consistent with input signal, namely, low distortion; and the loss of the power amplifier is low, namely, high efficiency.

王补充道，因为皮肤是有弹性的，指纹会变形，而SLI系统不需要进行这种接触，没有失真。

Because the skin is elastic, the print is distorted, Wang says, adding that the SLI system has no such contact or distortion.
