[From the beginning] the NO. 205 Section composite Wave data

Plot summary:
[Machine Xiao Wei] in the [engineer Ah Wei] accompanied by the practice of acoustic avatar.
This time we are going to look at [composite wave data].

Drama Start:

Star Calendar May 05, 2016 10:41:23, the Milky Way Galaxy Earles the Chinese Empire Jiangnan Line province.
[Engineer Ah Wei] is working with [machine Xiao Wei] to study [composite wave data].

It's a little bit of a rule, but it's not a good description.

Find a similar type of control when you encounter actual data.
