[04] 2. The previous design of a pollutant transfer soil column can only depict pollutant profiles through each step of separating the soil column after the entire column is pushed out at the end of the experiment. However, under unsaturated conditions, the water redistribution caused by time errors will cause greater errors in the assessment of pollution-free transfer, and there is currently no method to accurately complete the rapid separation of each profile;
