我们可以使用相同的标记读出时间(比如说，这样可以将“11：30”识别为“half past eleven”，而不是纯粹的数字)。
You can apply the same tag to speak the time (which will make it identify times such as 11:30 as "half past eleven", rather than just bare Numbers).
但是如果用纳米孔，实质上就不需要化学与处理和“放大”，取而代之的是，可以一次一个碱基对地读出单条dna链，也不用标记。
With nanopores, however, virtually no chemical pre-processing is required and no amplification. Instead a single strand of DNA can be read, one base pair at a time, and without the need for labelling.
可以使用 XML 解析器读出 标记，但在本例中使用一个正则表达式会更为容易。
You could use an XML parser to read out the tags, but it's easier in this case to use a regular expression.
