Normally, cells then briefly hyperpolarize: they become strongly negative on the inside relative to the outside by allowing potassium ions to rush out. 正常状况下，细胞接著会出现短暂过极化：因为太多钾离子涌出细胞，使得细胞内部变成带有相对较高的负电。
It is a drastic means to relax blood vessel and lower blood pressure by activating K+ channel and making cell membrane hyperpolarize. 通过激活K+通道使细胞膜超极化是一种强有力的松弛血管、降低血压的方法。
Active proton pump on the pollen grain membrane drives H+ efflux, hyperpolarize the membrane and triggers signaling transduction. 花粉细胞质膜上存在质子泵,由其活化导致的H+外流可以影响细胞膜电位,引发一系列信号转导过程。
