The earth has more mass and so part of this density is attributable to gravitational compression.
地球有更多的质量和密度，使这部分是由于引力压缩。
The other two, Primary (P) or compression waves and Secondary (S) or shear waves, penetrate the interior of the Earth.
另外两种，P或者“压缩波”以及S“剧烈波”，穿透地球内部。
The results show that a certain amount of the mixed rare earth oxide content in the batch can increase the cold compression strength and the thermal shock resistance of the bricks.
试验结果表明，在配料中加入适量混合稀土氧化物对提高耐火制品的常温耐压强度和热震稳定性能是有益的。
Shock compression has become an important method to advance our understanding of the deep Earth's interior, and has played an important role in the research of solid Earth science.
冲击波动态高压技术已成为人们研究、认识地球内部物质组成、状态及其性质的重要手段和方法之一，在固体地球科学研究中发挥着重要作用。
