【摘要】 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。更多还原

【Abstract】 Based on the test of electrostatic separation of Mallus spectabilis pollen,starting from pollen cell membrane potential and the charge of pollen in electrostatic field, in this paper the force and movement of pollen in an electrostatic field was analysed. The theory of electrostatic separation 2n pollen was studied and consequently an conclusion was drawn that the location of 2n pollen on the electrostatic field plate is lower than n pollen.更多还原
