Dear Prof. Baroni:
    Thank you for your kind attention!
    Yes, I totally agree with you. But the coordinates for the "quantum tunneling" are different from that for the
 adiabatic diffusion, and it seems not easy to find to fulfil the realistic processes. So what I need now is well accepted model to find this kind of coordinates. I have found some papers related to quantum tunneling, but I am still wondering: are there some widely accepted model to find the configurations for quantum tunneling? Could you please introduce me some good papers related or expertise advice? 
Thank you very much!
Best Wishes!
Yours Sincerely
L. F. Huang
