Thanks all. I found a tutorial at <a href="https://www.youtube.com/watch?v=KRkx8kjmXZw" target="_top" rel="nofollow" link="external">here</a> and followed its instructions. However, I couldn't get an ideal result when I do that with my PNG.

My original PNG is <a href="https://dl.dropboxusercontent.com/u/53704642/temp/cogs.png" target="_top" rel="nofollow" link="external">this one</a>.

The result I got is <a href="https://dl.dropboxusercontent.com/u/53704642/temp/cogs.svg" target="_top" rel="nofollow" link="external">this one</a>.

As you can see, the edge of the result became too smooth. I tried playing with other options in Trace Bitmap panel, but I still couldn't get the result I want. Is there a particular reason that my PNG couldn't be ideally converted?
