ELECTRE方法是建立在级别高于关系基础之上一种关系模型，级别高于关系是该方法的核心思想。
The ELECTRE method is a relation model based on outranking relation, which is the key of this method.
在不同的ELECTRE方法中，这些级别高于关系往往是针对特定的问题背景构造和提出来的，因此具有不同的表达形式。
In different ELECTRE methods the outranking relations are frequently constructed and proposed to some specific problems; therefore they have different forms.
马氏体钢抗杆式模拟弹防护系数随着强度的提高而提高，呈线性关系，含氮奥氏体钢穿甲防护系数远远高于同一强度级别的马氏体钢。
For mass efficiency of penetration, martensite steel increases in line with strength, and nitrogen alloyed austenitic steel is much higher than that of the same strength martensite steel.
