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.
强烈的恒星风压缩加热了星际尘埃，并在前方形成弧形的震荡波。
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.
确实，Cheng预计银河中心激震前沿的能量将近是超新星爆发产生的能量的一百倍。
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.
这个蓝色的“子弹”每小时飞行500万公里（300万英里），恰好能赶上激震前沿，此时冲击波因为星际物质的阻挡已经减速。

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.
