摘要
根据细胞双电层模型和电学原理,推出了植物细胞膜上电荷产生的细胞内压力的计算公式。利用该公式分析了植物细胞膜上电荷产生的电场力对细胞内压力的影响。得出了细胞的实际内压力和植物体的实际刚度比只考虑机械压力的理论结果要大些,细胞的实际破裂情况比只考虑机械压力时的理论分析结果要容易些三点结论。
A formula about cellular pressure produced by the el ec tricity on the plant cell membrane was deduced by the double electric al layer model of cell membrane and electrical theory. The effect on cellular pressure, which was given by the electric field force produc ed by electric charge on the plant cell membrane, was analysed throug h this formula. The results showed that the actual cellular pressure and the actual plant body stiffness were more than the theoretic valu es, and the actual rupture of cell was easier than that of the theo retic analysis when the mechanical pressure was only taken into accoun t.
