mass ratio

基本解釋

Of course, the mass ratio comes into it.
,當(dāng)然，質(zhì)量比率包含在其中。
He measured the charge to mass ratio of the electron.
他測量了電子的荷質(zhì)比。
The big question has been whether one grows before the other or if they grow together, maintaining their mass ratio throughout the entire process.
一大問題是，是否一類天體在另一類天體之前形成，或是他們一起形成，在整個過程中兩種天體都保持著這一質(zhì)量比率。

He measured the charge to mass ratio of the electron.
他測量了電子的荷質(zhì)比。
