The issue involves two aspects: the extraction of characteristics, and the measurement of the distance between two characteristics vectors, i. e. the problem of characteristic match.

这就涉及两个方面问题，一、如何提取特征，二、特征向量间距离如何测量，也就是特征如何匹配的问题。

Analyses show that the characteristic factor for oxide integrity E , i. e. the number of elements per defect, can be calculated from oxide capacitor leak current yield curves.

分析表明，从多个子列的氧化层电容漏电合格率的曲线可以求出氧化层完整性的表征因子E 值（每个缺陷包含的单元数）。

The dynamic characteristic of interbedded soil is similar to that of soft soil; and this property is caused by its special conformation, i. e. the feeble horizontal joint planes are overgrown.

初步分析结果表明：互层土具有软土的动力特性，这主要是由互层土的特殊物理构造造成的，即在互层土中存在很密的水平薄弱面。
