The reaction mechanism and vibrational excitation effect in $\mathbf{H}$ + $\mathbf{CH}$ $\to$ $\mathbf{C}$ + ${\mathbf{H}}_{\mathbf{2}}$ reaction is analyzed in detail by utilizing quasi-classical trajectory method. The capture time, vibrational excitation effect for the total integral cross sections (ICSs), rate constants, and rovibrational state resolved ICSs are studied. Results show that with the collision energy increasing, the direct mechanism is becoming increasingly important, but, the indirect mechanism is still important and even dominant. The analysis of the ICSs according to the maximum impact parameter and probability lets us to get a deep insight into the effect of vibration excitation on reaction.
