Since replacing chloride doesn't really work, the other option would be to replace the positive ion, sodium.

由于替代氯化物并没有真正起作用，因此另一种选择是更换正离子，也就是钠。

They're compounds made up of positive and negative ions, usually formed when an acid reacts with a base.

它们是由正离子和负离子组成的化合物，通常在酸与碱反应时形成。

Positive ions move to one electrode and negative ions onto the other.

正离子移动到一个电极， 负离子移动到另一个电极。

While the electrons move toward the middle, the positive gas ions head the other way.

当电子向中间移动时， 正气体离子向另一方向移动。

Alkali metals want nothing more than to dump off an electron and form a positive ion, or cation.

碱金属只想释放电子并形成正离子或阳离子。

This includes antacids that contain aluminum, calcium, or magnesium, all of which are positive ions that can bind with the negatively charged phosphate and block absorption.

这包括含有铝、钙或镁的抗酸剂，它们都是阳离子，可以与带负电荷的磷酸盐结合并阻碍其吸收。

When the eel is ready to strike, channels on one side of the cell open and positive ions rush in generating a current and zap!

当鳗鱼准备攻击时，细胞一侧的通道打开，正离子涌入产生电流并击打！

Individuals will also have a high anion gap, which reflects a large difference in the unmeasured negative and positive ions in the serum, largely due to this build up of ketoacids.

患者也会有阴离子间隙偏高，指的是血浆中未测定的阴阳离子浓度差值高，主要原因是酮酸的积累。
