不过我确实觉得，钙含量的一点点改变就能给我的身体和精神造成如此巨大的影响，实在是不可思议。

But I find it remarkable that a small change in calcium could have such a big effect on my body and my mind.

我注射了两剂双磷酸盐，但是我血液中的钙含量在注射完几周后就开始反弹。

I had two doses of this - delivered directly into my vein, but after each treatment my calcium levels started to rise again within weeks.

肾结石通常由钙质形成，测试表明我血液中的钙含量严重超标。

Kidney stones are most often formed from calcium - indeed, tests showed the levels of calcium in my blood were far higher than normal.

So what we know is that these 3 d orbitals are higher in energy than 4 s orbitals, so I've written the energy of the orbital here for potassium and for calcium.

我们所知道的是,3d轨道能量,比4s轨道能量高，所以我写出了,钾和钙的轨道能量。
