It is proposed that mean stress effect should be divided into two aspects, i. e. static effect and dynamic effect for fatigue under complex loading.
对于复杂载荷下的疲劳问题，应该把平均应力效应分为“静态效应”和“动态效应”两个方面。
Static coefficients are defined to describe the static effect of wind on bridge, and the aerodynamic derivatives are used to describe the aerodynamic effect.
静力三分力系数用于描述风对桥梁的静力作用，气动导数是颤振和抖振分析方法的核心。
At present, compaction machinery products include:frog tap machine, type roll road, static effect roll road, vibratory roller and walk-behind vibratory roller, etc.
蛙式打夯机、轮胎压路机、静作用光轮压路机、振动压路机和手扶振动压路机等是国内压实机械的主要产品。

浇注的聚氨酯层粘接牢固、耐磨，不容易脱落、损坏，防静电效果好，整体结实、美观。
The static effect affects only ultimate fracture condition (the critical residual strength), while the dynamic effect affects damage evolution and residual strength degradation rate.
静态效应只影响最终断裂条件，而动态效应影响疲劳过程中的损伤演化规律和强度退化速率。
