脆性材料单次冲击和二次冲击或低负荷压缩冲击性能方面有很大的差别。

There is a distinct difference in the strength characteristic of brittle materials between single impact and double impact or slow compression.

冲击波形成了一个由压缩气体分子构成的圆锥体，它朝四面八方向外和向后移动，一直延伸到地面。

The shock wave forms a cone of pressurized air molecules which move outward and rearward in all directions and extend to the ground.

当高速行进的超新星冲击波与稀薄的星际气体相撞时，气体受到压缩和加热，因此而发光。

As the supernova blast wave slams into tenuous clouds of interstellar gas, the resulting collision heats and compresses the gas, causing it to glow.
