by-time

The mass was calculated by timing the orbit of Eris' moon Dysnomia.

通过对厄里斯卫星--戴丝诺米娅运行轨道计时后计算出了厄里斯质量。

"A digital watch shows the time by electronically lit up numbers, e.g. 1021."

"手表是用电子显来表时间,1021。"

I passed the time by counting the cars that drove past the school.

我用驶过学校小汽车来消磨时间。

Your patience is tested by time.

时间将考验你耐心。
