电池电流

This battery can supply a current of 4 mA.

这个电池能提供 4 毫安的电流。

But does this work in the case of a voltaic battery?

但是伏打电池中的电流是否也是这样流动的呢？

This model couples the conservation of mass, momentum and species equations as well as water transport equation in the membrane.

刚ler研究了质子交换膜内水、温度和电流密度的分布。wangls和You[6] 分别对PEM燃料电池阴极内的汽液两相传质进行了不同侧重的研究。

Their electrochemical properties were investigated by charge-discharge of constant current, cyclic voltammogram, impedance spectrum and so on.

因其兼备传统电容器功率密度高和二次电池能量密度高的优点，以及可实现瞬间大电流放电，充电时间短、效率高，使用寿命长，无记忆效应以及基本无需维护等非常独特的性质而倍受关注，特别是在信息技术、电动汽车、航天航空和国防科技等方面有广阔的应用前景而受到广泛的研究[1-3]。

The sling attaches to bone around the eye.

眼皮吊粘附于眼睛周围的骨骼，而后它被连到一个静电聚合物上，这种聚合物通常是一块可以通过电压变化来控制其扩张或收缩的弹性塑料，隐藏在太阳穴内空洞部位的一块微型电池为这种聚合物提供动力，当电流存在时，眼皮吊肌肉会收缩，眼睛保持睁开状态，一旦电流消失眼皮就会合上。

The sling attaches to bone around the eye. It's then linked to an electrostatic polymer—basically a piece of flexible plastic that expands or contracts via voltage change. A tiny battery hidden in a natural hollow in the temple powers the polymer. Electrical current keeps the muscles contracted and the eyes open. Kill the current and the lid closes.
