Roughly around under the surface ECG identified two bypass, bypass atrial fibrillation by alternating two downstream, suggesting that AV conduction block in the right way there.
大致可根据体表心电图确定有左右两条旁路，经两条旁路快速房颤交替下传，提示传导阻滞在房室正道中存在。

The study of NMR showed that every block of polymer I has alternating structure.
NMR研究表明该嵌段聚合物各段都具有交替结构。
