shock front

基本解释

Its strong stellar wind precedes it, compressing and heating the dusty interstellar material and shaping the curved shock front.
強烈的恒星風壓縮加熱了星際塵埃，竝在前方形成弧形的震蕩波。
Indeed, Cheng expects that the energy of the shock front at the galactic centre is nearly 100 times greater than that created by a supernova explosion.
確實，Cheng預計銀河中心激震前沿的能量將近是超新星爆發産生的能量的一百倍。
This interstellar "bullet," traveling over three million miles per hour (5 million km), is just catching up with the shock front, which has been slowed by plowing into interstellar material.
這個藍色的“子彈”每小時飛行500萬公裡（300萬英裡），恰好能趕上激震前沿，此時沖擊波因爲星際物質的阻擋已經減速。

In front of him lies an Israel in shock, dazed and confused by the Barak paradox.

Once you've come down from the initial shock, HTC's subtle flairs begin to peek out, like the solid colored speaker grill that serves to break the front face's expanse of glass with a shock of vibrancy.

The Rolls-Royce Ghost rides on a sophisticated double wishbone suspension up front with a multi-link array at the rear and automatic damping height-adjustable shock absorbers at all four corners.
