The traditional method of designing radiation part is to determine the different angle and depth of the gap corresponds to the conductance through experiments.
设计辐射波导，传统的方法是通过实验来确定不同倾角和不同切口深度的缝隙对应的电导数据。

These, say the researchers, correspond to drops in conductance when DNA strands slide across the gap via a biochemical process known as translocation.
