最后给出基于建立信号模型和互功率谱相位的时延估计方法。该方法对噪声和混响均具有很强的鲁棒性。
A time delay estimation method based on onset signal and CSP is proposed, it's robust to noise and reverberation.
既然慢生根瘤菌也会生成根瘤从而建立共生关系，它们一定使用了不同的信号分子来实现这个目的。
Since the Bradyrhizobium strains still form nodules to establish symbiosis, they must be using different signalling molecules to do so.
