容若№棲的回答：

convincing  主语为物 (没有生命)

e.g. His explanation was too pat to be convincing.

convinced   主语为人 (有生命)

e.g.  I'm convinced that the only thing that kept me going was that I loved what I did.

上面的一对词例子很多，比如: interesting/interested; exciting/excited; exhausting/exhausted

 

convincible  表示"具备…能力"

e.g. It would be more convincible if your paper include some quantitative simulations or statistical analysis.
