The tests first flow water or other inert substances through the laser to verify its integrity. Next, the laser\'s chemicals flow through the laser to confirm sequencing and control.

测试首先将水或其他惰性物质通过激光以验证其完整性，随后激光器的化学流通过激光以确保序列和控制。

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。

The control flow (i.e., the sequencing of these invocations) is implicit and emerges as the rules fire off.

控制流(例如这些调用的顺序)是隐式的，并在规则触发时显现出来。

And in the past week, two groups of geneticists, one at the Michael Smith Genome Sciences Centre in Vancouver, British Columbia, and the other at the Centres for Disease Control and Prevention in Atlanta, Georgia, have succeeded in sequencing the genomes of coronaviruses isolated from patients in Toronto and Asia.

In the work of NCBI Staff Scientist and genomics expert Martin Shumway, distilling these large volumes of raw sequencing data requires more sophisticated computing algorithms, intensive quality control and indexing for online searchability by the science community.
