本文仅涉及地震波传播及爆破方法选择两个课题，研究表明：在这类课题中，利用动态光弹性法有其优越性。
This paper only involves selection of detonating methods and propagation of earthquake waves. The study shows the superiority of using dynamic photoelasticity in the research area.
爆破与高速冲击载荷产生的应力波在弹性结构物中的传播，在理论分析上极为困难，但这类问题可以用动态光弹性法进行分析。
Stress wave propagating in elastic structures under impact or explosive loading is a very difficult problem analytically. But the problem could be analysed by dynamic photoelasticity.
