They work because certain materials, such as bismuth telluride, generate an electrical potential difference within themselves if one part is hotter than another.

它们之所以能起作用是因为一般的材料，比如碲化铋，如果其中一部分比另一部分热，内部就会产生电位差。

Gastric mucosal blood flow (GMBF), electrical potential difference across gastric mucosa (PD), ulcer index (UI) and other indexes were measured, respectively.

分别测定胃粘膜血流量(GMBF)、胃粘膜跨膜电位(PD)、损伤指数(UI)等多项指标。

And the electrical energy is the product of the charge on the electron times the voltage which is the potential difference through which the electron was accelerated. And so this allows me to, by increasing the voltage, increase the energy on the electron.

电子能量是电子上的电荷数,乘以电压的结果,这是种内在的差距,通过它电子运动得以加速，这也让我，通过增强电压，来增加电子能量。

They could also provide an atmospheric electrical potential difference, which otherwise might not exist, to achieve precisely aimed and timed lightning strikes.

In the brain, the signals travelling through the synapses rely on action potential, which is the electrical energy created by the difference in concentrations of charged atoms (ions) on the inside and outside of neuron, which move back and forth through ion channels.
