主　　题：soil steam disinfection steam capillary diameter steam capillary vent soil temperature soil water content 

摘      要：The soil steam injection method is one of the most effective disinfection methods,and the determination of the steam pipe structure parameters is very *** steam capillary diameter(SCD)affects the steam flow field in each pipe,which in turn affects the steam changes in the soil flow range and soil temperature(ST).Larger SCD would make lower ST in clay loam,silt loam,and sandy clay *** effectiveness of an SCD of 10 mm was verified by a mobile disinfection test at walking speeds of 10 cm/min and 30 cm/min under soil water content(SWC)of 15%and 35%,*** results showed that when the walking speed was 10 cm/min,the initial SWC was proportional to the ***,when the walking speed was 30 cm/min,the law was exactly the opposite;that is,the initial water content is inversely proportional to the *** research can provide a theoretical research foundation for increasing soil temperature for efficient soil steam disinfection.
