The BESIII experiment functions as an electron-positron collider in the tau-charm energy region, dedicated to investigating various physics objectives related to charm, charmonium, and light hadron decays. Within these goals, the accurate identification of particles plays a pivotal role, ensuring both high efficiency and minimal systematic uncertainty. In the context of the BESIII experiment, the particle identification performance heavily depends on two key measurements: the energy deposition per unit length (dE/dx) acquired from the main drift chamber sub-detector and the time-of-flight measurement from the time-of-flight sub-detector. This paper specifically delves into the dE/dx aspect, presenting a comprehensive overview of the dE/dx software utilized in the BESIII experiment, encompassing simulation, correction, calibration, and reconstruction processes.
