摘要(Abstract)：

在一次爆破加载同时得到爆破模型动态等差线与等和线条纹图的基础上 ,采用部分改变物光光程的方法求得等和条纹的级数。为检验尚有争议的动态等差条纹级数判据 ,利用设计的一种应力波在边界反射后的爆破实验模型进行研究 ,解决了复杂条纹图的判读问题
The transient isopachic and isochromatic fringe patterns for explosive model are acquired at the same time in one blasting loading run. On the basis of changing part object optical path ,it is used in the judgement isopachic fringe order of the blast loading. For proving the method which is used to identify isochromatic fringe orders, the experimental model is devised when stress wave is reflected at the free boundary of the hole. Identification of the fringe patterns in which stress waves are reflected and interfered is solved.
