为评价管材拉拔中的不均匀变形，提出用管材拉拔前后截面形状变化指数Q描述截面变形的不均匀性。

It is put forward in this article that the cross section deformation index Q can be used to evaluate the inhomogeneity of deformation in tube drawing.

它着眼于地震灾害危害性在一个城市内空间分布上的不均匀性，以综合的、层次的指数体系来揭示出城市内各局部区域间危害性的相对水平及其形成原因。

This composite and hierarchical index focuses on the spatial imbalance of the earthquake disaster risk within a megacity, and gives the relative risk level among the local areas of the city.

介绍了衡量套管不均匀变形程度的指标一截面形状变化指数，并用试验数据对该指标的应用进行了检验。

The section form variation coefficient which is the judgment of non-uniform deformation degree index of casing is introduced. And the application of the index is examined by the test data.
