I'm not sure what Mr Hartl is trying to say here.

This is an article which was written by Vietnamese that I took it on Internet. Then I translated into English and certainly Mr Hartl didn't say that!
Please help me correct all of message! Thanks a lot!

Sorry, there are too many places where I don't know what you're trying to say. Perhaps a translation like that is overambitious at this stage?

You are translating more specialised English, so a cross reference is helpful from a page written in English on the same subject. This link will give a written English version similar to your original text (if the moderators will allow this, since it's appropriate to the nature of your question.)
