英文摘要：

The progress on reseanch of CO2 induced corrosion is reviewed in this paper. The corrosion mechanism and the main factors controlling the corrosion process were also summerized. Temperature, partial presssure of CO2, pH, film of corrosion product and flow rate etc. are important factors to the CO2 induced corrosion. The relevant protection measures are also introduced in this paper which are the use of inhibitors and selectors of material.
