Forgings yield parts that have high strength to weight ratio, thus are often used in the design of aircraft frame members.

锻造生产的零件具有较高的强度重量比，所以常被用在飞机结构零件的设计中。

Based on which we find that although the yield strength of 93w increases as the shock pressure increases, but the ratio of the yield strength to the shock pressure decreases.

得到了93 W合金在高压下材料屈服强度随冲击压力的增大而增大，但其与冲击压力的比值则随冲击压力的增加而减小的变化规律。

The yield strength, yield tensile ratio and toughness are major quality indexes of steel pipe (board). However, it is quite difficult to determine them reasonably.

屈服强度、屈强比、韧性等是钢管(板)的主要质量指标，合理确定这些指标的数值有相当难度。
