Since the molecule is easily ionized, voltage drops across the nanopore help "pull" the DNA through.

由于分子很容易被电离，通过纳米孔的电压落差有助于牵引dna穿过微孔。

When the AC voltage drops to zero and begins to increase in the negative direction, the SCR remains turned off.

当AC电压下降到零，并开始增加在负方向上，这个SCR仍然关闭。

When distribution system voltage drops, dynamic voltage restorer (DVR) can maintain the sensitive load side voltage stability.

配电系统电压跌落时，动态电压调节器可以维持敏感性设备的电压稳定。
