Ooooooooooops, I got through it, thanks for you help! You are right! No further questions at all...

Thanks for your reply.^^ You mean like this? But it's not the original equation. I know that the commutator of position and Hamiltonian is equal to velocity multiplies by i and hbar(positive or negative sign added). But what I want to know is how to transform the position operator "itself"...

By the way, I don't know how to show the pics directly, sorry about that.
