利用实时全息干涉计量摄影装置记录有机玻璃板微破裂过程中应力（场）的变化，讨论了微破裂的丛集过程及其与应力（场）的关系，宏观裂缝的分叉和延伸规律，大破裂与微破裂的关系。研究结果表明，大破裂发生前微破裂有丛集（成核）现象，微破裂的丛集与局部应力集中有关，大破裂（宏观裂缝）延伸方向是应力场高梯度变化方向，大破裂的发生位置与微破裂的丛集无明显关系。
The changes of stress (field) during the micro-rupture of the plexiglass plate were recorded by real-time holographic interference photogrammetry equipment. The micro-rupture cluster process and its relationship with stress (field) were discussed. The rupture and extension of macroscopic fracture, Relationship with micro-rupture. The results show that the micro-bursts have cluster (nucleation) phenomena before the occurrence of macro-rupture. The micro-bursts are related to the local stress concentration. The direction of the macro-cracks is the direction of the high-gradient of stress field. The location of the macro- There was no significant correlation between micro-ruptured clusters.
