normal energy level

基本解釋

The experimental mice did not eat the full amount presented to them yet their energy expenditure remained at a normal level.
實驗組小鼠沒有吃光提供給它們的全部食物，但它們的能量消耗仍處于正常水平。
Under normal conditions, atoms contain two electrons per energy level surrounding their protons, with the electrons spinning in opposite directions.
在正常條件下，原子含有每周圍的質(zhì)子能級兩個電子，與紡紗在相反方向上的電子。
The aim of both teams is to tap into high-altitude wind, which is an energy source that is more abundant and reliable than the ground-level wind on which normal turbines depend.
兩個研究小組的目的是一致的：利用更加豐富、穩(wěn)定的高海拔風(fēng)能發(fā)電，而普通的渦輪發(fā)電機(jī)則依賴于地表風(fēng)能。
