运用“灰色系统”理论的关联分析法对Wel-ten80c 80kg级低合金高强钢焊接过热区韧性的变化规律进行了分析。采用关联度(R)的概念较科学地确定了最佳工艺参数t_(3/5)。
The relationship between the toughness and the toughness of Wel-ten80c 80 kg low-alloy high-strength steel in the over-heating zone was analyzed by using the “gray system” theory. The concept of relevance (R) was used to determine the optimal process parameters t_ (3/5) scientifically.
