This nanopore-based sequencer is one 10,000th the size of your traditional genome sequencer.

这个纳米孔测序仪只有传统基因序列测定仪的万分之一大小。

Other labs have experimented with similar nanopore-based approaches to sequencing but have found it difficult to control how quickly the DNA strand feeds through the nanoscale hole.

其他实验室已经试验过类似的纳米孔测序方法，但研究人员发现，很难控制DNA链穿过纳米孔的速度。
