在静电分选海棠花粉的实验基础上，从花粉细胞膜电位和花粉在电场中荷电的角度出发，作了花粉在静电场中的受力及运动分析，研究了２ｎ 花粉的分选机理，从而得出了２ｎ 花粉在极板上的位置比ｎ 花粉位置要靠下的结论。
Based on the experiments of electrostatic separation of Begonia pollen, the pollen cell membrane potential and the charge of pollen in the electric field were used to analyze the force and movement of pollen in the electrostatic field. The mechanism of pollen sorting was studied. The conclusion is that the position of 2n pollen on the plate is lower than that of n pollen.
