摘要：A new mathematical model is developed for peristaltic transport in the esophagus. Manometric measurements of luminal pressure have been obtained in the esophagus and interpreted both biological and mechanical point of view. Biological data analysis pointed out that pressure distribution has a polynomial form along the esophagus. However, it has been considered as sinusoidal in calculations by scientists. Therefore, a mathematical result does not possibly fit same form with biological data. The developed model is calculated successfully with pressure distribution along the esophagus. The model is applied to a single contraction wave of normal swallowing in the esophagus. Analytical calculation from the new model on pressure distribution is in qualitative agreement with experimental observations.
