与一般干涉仪相比该系统也因相位压缩而使工作的线性范围扩大了220倍。
Compared with common interferometers, the linearity range of this system was enlarged by 220 times for phase compress.
相位基本与其它观测结果相符，而变化幅度大1倍，我们的结果更接近于理论估计结果（0.17%）。
The phase accords with other observation results basically, while the amplitude of variation is double. Our result of the amplitude is more close to the theory value (0.17%).
研究结果表明，群速度失配会导致二倍频光脉冲宽度的增大和转换效率的降低，非线性相位调制使二倍频光脉冲形状发生畸变，降低转换效率。
The results show that group-velocity mismatching is the main reason of the broadening of the second harmonic pulse and could lead to the decrement of conversion efficiency.
