| 摘 要： | 提出从全场等差条纹图中的可靠数据点上测取数据，进而求出材料条纹值的一种新方法，这种方法与传统方法相比，可提高材料条纹值的精确度，且可采用有缺陷的试件（如有气泡）进行测定，此法同样适用于等厚材料条纹值及冻结的材料条纹值的测定。

| Abstract: | A new method is present for measLiring material fringe value from wolde-field isochromatic fringe pattern and the data can be taken at locations having fullconfidence. Compared with the traditional method, greater accuracy is obtained.Airregular spedmen(for example having bubbles on the surface) is employed also formeasurement. The method holds good also for measuring material fringe value ofisopachic and frozen speciment. |
