Abstract:An indoor experimental simulation system was home-designed and fabricated to study moisture transport mechanism in soil at different temperatures.By using water bath heating instead of resistance wire heating directly,the puzzle of uneven and uneasy temperature controlling was solved.In order to control and acquire temperature data automatically,Serial Communication Interface Technology was adopted to link intelligent temperature control instrument with PC.It took nearly one year to carry out 7 groups of experiment.Results show that this experimental system is stable and compatible;the temperature fluctuation range is within ±1℃ during 30 days.So this experimental system can be used to simulate moisture transfer process in soil under temperature effect.
Keywords:moisture transport  temperature effect  test system
