The container loading problem occurring in on the spot freight production is often with several constraints and objectives, I.
现场集装箱装载问题多为多目标、多约束优化的复杂问题。
This paper discussed the fatigue strength of single-spot-welded joints under constant and variable amplitude loading. The fracture mechanics was also used to analyse the experimental results.
讨论了恒幅及变幅载荷作用下，拉剪点焊接头的疲劳性能，并应用断裂力学对实验结果进行了分析和整理。
