Notes. (a) tcold, twarmup, and Tmax are time spans of the cold and warm-up phases and maximum temperature that are used in the evolving physical models. (b) Tgas and Tdust are gas and dust temperatures that are used in the static models. (c) χ and G0 are used to calculate the rate coefficients of photodissociation and photodesorption induced by UV photons, respectively. (d) ζCR and 
are used to calculate the rate coefficients of photodissociation and photodesorption induced by cosmic ray particles, respectively.
(e) Boldface indicates the fiducial values adopted in our simulations.
