摘　　要：本文应用影像云纹法、频率编码法对短圆柱组合薄壳的屈曲现象进行了研究,给出数字化的初始曲面和屈曲模态图象,将现代光力学法用于快堆主容器结构稳定性模拟体分析实验研究,取得较好的实验结果。本项目的研究成果,为我国制定快堆主结构的安全性评估提供科学依据。The buckling mode is studied by photomechanical measurement in which shadow moire interfer-ometry and profilometry are employed by a shor cylindrical sectioned thin shell. The digital images relation of contour line that can be readily processed to surface shape of the object, namely buckling mode. The bucking experiments of the model shells are well done, and some constructive achievements are obtained.
