If you or other classmates here want to post your technical writings and ask us for suggestions, I am sure those who are interested will be happy to chip in.
My personal understanding is that technical writing, ultimately, is not too different from our regular writing. In my college years, we had classes on 旅游英语，外贸英语，商业英语，etc. Later I found that those classes just introduced vocabulary/jargon in those fields. The basic grammar and writing style were not so different from what I learned from our basic English or writing class.
As we all are in different fields, when you post your writing, you might want to modify your writing a little bit, so that it won't be too technical or too jargonistic.
