It is well known that the rain-drops on the roof are smaller than those that fall on the street.
正如我们所知道的，落在屋顶的雨滴比落在街上的雨滴要小一些。
These, say the researchers, correspond to drops in conductance when DNA strands slide across the gap via a biochemical process known as translocation.
研究人员认为这是由于DNA链通过时产生了一种叫做易位的生化过程，使得石墨舟的电导发生了下降。
