【Abstract】 This article deals with the basic principles of dielectric separation of tree seeds. The ideal seed model and mathematical model of dielectric separation are established. The process of seed polarization and moving condition in the electric field are developed. The polarization force is calculated while its way of forming analyzed. The main factors to affect polarization force are discussed. Based on the mathematical model, the separation parameters are discussed and their effect on seed dielectric separation are pointed out.更多还原
