2. A method of how to measure the signal's phase noise by spectrum analyzer is introduced. 本文介绍利用频谱分析仪测量信号相位噪声的方法。
3. In normal cells, cohesin can connect sister chromatids only in S phase, even though newly synthesized cohesin complexes can associate with DNA in the subsequent G phase (5, 6). 在正常细胞中,内聚力只在细胞分裂的S期联合染色体,尽管新合成的内聚力联合体能在G期联合DNA(5,6)。
