The basic idea is this: As the remnant of a dead star hurtles through space at up to 30 million kilometers per hour, it creates a shock wave as it interacts with the so-called interstellar medium.

基本观点是这样的：由于死亡恒星的残骸在太空急速飞驰，速度高达每小时3，000万公里，当它跟所谓的星际介质之间发生相互作用时，就会产生激波。

Shortly after, the shock wave pierces the star's surface, blasting it apart and strewing its luminous debris across light-years of space.

片刻之后，震波穿过恒星的表面，将其震碎，并使其仍旧发光的残骸散播至数光年之外的空间（请看有关的超新星残骸图片

The exponential regularity of the shock wave attenuation coefficient versus the charge diameter in PMMA was obtained by fitting experimental data.

利用锰铜压阻传感器法测量了某聚奥传爆药在不同直径下的小尺寸装药爆轰输出冲击波经不同厚度有机玻璃隔板衰减后的冲击波压力，通过对实验数据进行拟合，得到了有机玻璃介质中冲击波衰减系数与装药直径的指数型关系。

Powerful shock wave will break down the primary crystal and the growing dendrite, making them particle crystal. With the stirring of acoustic streaming, particle crystal is dispersed in melt, as is equal to increase the number of external nucleus.

强烈的冲击波会击碎初生晶体，使之成为破碎的晶核，在声流的搅拌作用下，又使其弥散地分布于熔池中，相当于增加了外来核心，因而使晶粒得到细化。

A method and apparatus for increasing the propelling force of pulse engine features that the fuel nozzle of pulse explosion engine is arranged in combustion chamber to close jet tube exit, and the fuel is reversely sprayed out to generate a shock wave barrier near the jet tube for preventing the airflow from flowing out of the combustion chamber, resulting in raising the pressure in combustion chamber and in turn increasing the propelling force.

本发明公开了一种提高脉冲发动机推力的方法和装置，它是通过将脉冲爆轰发动机的燃料嘴置放在燃烧室中靠近喷管出口附近，并使燃料逆向喷出，在燃烧室内靠近喷管附近形成一道阻止气流流出燃烧室的激波，激波的作用是使燃烧室压力升高，从而的到较大的推力。同时由于本发明的结构特别的简单，所以实现非常容易，并且工作效果十分显著。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
