Contour modulation is a technique in which a phase-modulated signal waveform and amplifier output impedance work together to maintain higher efficiency over a sizable output power back-off.

轮廓调制结合了一种相位调制信号的波形和放大器的输出阻抗，可在某个较大型输出电源关闭后保持更高的效率。

In the optimization phase, we develop a predictive model for the system to find useful operating conditions through response surface contour plots and perhaps mathematical optimization.

在优化阶段，我们开发了一个系统的预测模型，通过响应面的等高线图或者数学优化，去寻找合适的操作条件。
