其次，化学家想要将他们的环形聚合物与带电原子结合，例如钾离子和锂离子。

Next, the chemists would like to bind their rings to other charged atoms, such as ions of potassium and lithium.

例如，奶酪、加工过的肉、面包、汤、快餐和糕点通常含有较多的钠而不是钾。

For example, cheese, processed meats, breads, soups, fast foods, and pastries tend to have more sodium than potassium.

例如，钾离子通道在基底神经节上广泛表达并在帕金森症中也起到关键作用。

For example, potassium channels are widely expressed in basal-ganglia neurons and play crucial roles in Parkinson's disease.

In addition, the kidney controls the composition of your body of many important ions, sodium bicarbonate which is important in pH balance, potassium.

此外肾脏还能控制,体内很多重要离子的浓度,例如碳酸氢钠,它对于酸碱平衡十分重要,还有钾离子

So, for example, here we're showing rubidium and potassium and sodium plotted where we're plotting the frequency -- that's the frequency of that light that's coming into the metal versus the kinetic energy of the electron that's ejected from the surface of the metal.

让大家看来都是可以理解的事情,就是把不同金属的观测结果,画到一张图里面来，例如这里,我们展示的是钠，钾,铷的频率-这是照射金属的光的频率,和金属表面出射电子动能的关系。
