Some of the highly compressed material at the center of the impact site springs outward, once the impacting body either ricochets or disintegrates.

在那个撞击点中心的一些被高速压扁的物质向外弹出，一旦撞击，要么弹起、要么粉碎。

So, that's an extreme example, going from a slightly compressed JPEG to a highly compressed one, one-eighth the original file size.

He suggested that the universe began in a state of highly compressed hot plasma – a sort of hot soup of elementary particles.

他认为宇宙起源于 一种高度压缩的热等离子体——一种 基本粒子的热汤。

They have a crust, probably a few centimeters thick, made of highly compressed but more or less normal matter, squeezed into a kind of highly stiffened crystal state.

它们也有地壳，可能有几厘米厚，或多或少是由正常物质构成的，它们经过了高度压缩，被挤压成一种高度硬化的晶体状态。

When the core collapses down to about 20 km in diameter, it's essentially a ball of neutrons with some protons and electrons here and there that survived, and a crust of normal but highly compressed matter on top.

当核坍塌到直径约20公里时，它基本上就是一个中子球，还含有一些幸存下来的质子和电子，以及一层十分普通但高度压缩的物质外壳。
