单词	depolarize
释义	depolarize /diːˈpəʊlərʌɪz / (also depolarise) verb [with object] Physics Reduce or remove the polarization of: the threshold necessary to depolarize the membrane... Light passing through such a liquid crystal can be polarized and depolarized by changing the field and has led to the liquid crystal displays we see in watches, microwaves, and laptop computers today. The positive charge that they carry produces a further membrane depolarization, which activates additional sodium channels, so depolarizing the membrane even further. The ability of the plasma membrane to depolarize remains functional in the rho cells as evidenced by the release of insulin with the depolarizing agent KCl. Derivatives depolarization /diːˌpəʊlərʌɪˈzeɪʃ(ə)n / noun ... Whereas increasing temperature accelerated fluorescence depolarization, increasing solvent viscosity slowed the process down. As the channel opens upon a depolarization, the trapped ion can escape to the intracellular medium increasing the stability of the bound toxin. Polarization or depolarization of the membrane voltage opens the gate subunits and permits a flood of calcium ions through the cell membrane.
