reduce cell membrane charge difference
When a nerve or muscle cell depolarizes, the electrical difference across its membrane becomes smaller.
Mẫu sử dụng:
[a neuron/cell/membrane] depolarizes; depolarize [a neuron/cell/membrane]
Lỗi thường gặp:
In physiology, depolarize is not the same as repolarize; repolarize means to return toward the resting electrical state after depolarization.
Từ đồng nghĩa
excite (broader term; suggests making a nerve or muscle cell active)
|
activate (less technically precise; means to cause activity)
Từ trái nghĩa
hyperpolarize (means to increase the electrical charge difference across a cell membrane)
|
repolarize (means to restore the membrane toward its resting polarized state)

3
remove physical polarization
To make polarized light, radiation, or a signal no longer strongly polarized.
Mẫu sử dụng:
depolarize [light/radiation/a signal/a material]
Lỗi thường gặp:
This technical sense is usually about polarization as a physical property, not about political disagreement.
Từ đồng nghĩa
unpolarize (rare and less common; means remove polarization)
|
randomize polarization (more explicit technical phrase, especially for light)
Từ trái nghĩa
polarize (means to give light, radiation, or a material a particular polarization)

reduce electrode or battery polarization
To reduce a chemical or electrical effect that makes an electrode or battery work less efficiently.
Mẫu sử dụng:
depolarize [an electrode/a cell/a battery]
Lỗi thường gặp:
This sense is mainly technical and is different from depolarizing people or opinions.
Từ đồng nghĩa
reduce polarization (clearer descriptive phrase used in technical explanation)
|
counteract polarization (emphasizes opposing the unwanted effect)
Từ trái nghĩa
polarize (means to produce polarization at an electrode or in a cell)
