The method uses a fictitious acoustic sensor technique, and, with fewer acoustic sensors, can realize the same location performance as that obtained by using a primaryaccessory square array.

该方法采用虚拟传声器技术，用较少的传声器能达到主 从式正四方形阵的定位效果，从而解决了单四方形阵不能远距离定位的问题。

Well, turns out that with arrays, not to make this too trippy too soon, but Arg V bracket something is a string, you can also use square bracket notation to go to a specific letter in a string, because little teaser a string is just an array.

好的，结果用那个数组，不要使这个很快引起幻觉，但是Argv什么的，是一个字符串，你也可以用方括号定位到,字符串中的一个特定的字母，因为一个字符串只是一个数组。
