测量了激光照射后的受拉铝板试件的剩余强度，观察了不同激光照射时间下的裂纹扩展情况，并首次利用高温精细网格技术测量出试件上由激光破坏引起的裂纹尖端的残余变形场，为激光照射金属结构的实时动态变形测量提供了新的手段。
The residual strength of the tensile specimens after laser irradiation was measured. The crack propagation under different laser irradiation time was observed. For the first time, the residual deformation of the crack tip caused by laser damage on the specimen was measured by high-temperature fine grid technique Field, provides a new means for real-time dynamic deformation measurement of laser-irradiated metal structures.
