| 摘 要： | 在一次加载同时得到爆破模型的动态等差线与等和线条纹的基础上，采用部分改变物光光程的方法求得等和条纹的级次，它对今后的爆破条纹判读具有重要意义；并以此为据证实了目前采用的爆破等差条纹判读方法的正确性；发现在两种条纹图上存在着特殊的条纹对应区域，它有益于更方便地进行几种条纹图的判读。

| Abstract: | In this paper, the transient isopachic and isochromatic fringe patterns are acquired at a first time in an explosive load. On the basis of changing part object optical path, it is used in the judgement for dynamic isopachic fringe order of the blast loading. Accordingly, it is proved that the methods which are used to identify isochromatic fringe orders are correct, the auther finds out that there are paritcular responding regions in two kinds of fringe patterns. This method will be a great help for judging orders to different kinds of fringe patterns. |
