But after the X-ray pulse passes through, the cloud fades to its normal brightness.

但当X射线脉冲通过后星云就暗淡下来回到通常的亮度。

The electrochemical behavior of this system was studied by the methods of normal pulse polarography, linear sweep and cyclic voltammetry.

用常规脉冲极谱法、线性扫描和循环伏安法等研究该体系的电化学行为。

Do the movement several times, and at the same time, lift lower limbs gradually to straight position until pulse regains the normal condition before the race.

如此反复几次，同时上肢慢慢抬起、直立，直至脉搏恢复至运动前正常脉搏。

If the X7500 "Athena" somehow managed to fail to attract your attention and you found the Vox, Libra, Love, and Cavailer positively forgettable, first verify that you have a pulse (because we really don't think that's normal) then check this out: HTC's 2007 arsenal is shaping up to be a doozy, with several previously-unknown models stepping into the spotlight.
