amplitude fluctuation meaning in Chinese

振幅摆动
振幅波动
振幅起伏

The amplitude fluctuation and according system performance degradation induced by xpm is also studied through numerical simulation . the timing jitter caused by xpm can also have great impact on system performance . by employing lagrangian variational method and statistical method , the timing jitter caused by xpm in strong dispersion managed rz systems is studied in chapter 3
通过仿真也研究了波分复用系统中由于交叉相位调制效应引起的幅度抖动从而导致系统性能的恶化；交叉相位调制引起的时间抖动对系统性能也有较大影响，利用拉格朗日变分方法和统计分析的方法，第三章讨论了强色散管理归零码系统中交叉相位调制引起的时间抖动。
Meeting to the demand of linear power amplifier ( lpa ) compensation technology in the modern communication , this thesis presents a reflection adjustable phase shifter using the reflection theory , realizing phase adjust in a wide range with a little amplitude fluctuation and discussing the principle and experimental results
摘要针对现代通信中线性功率放大器的补偿要求，介绍一种利用反射理论设计可调移相器，实现大范围移相，同时幅度波动很小，并详细讨论了它的工作原理和实验结果。
