The results show that the main factors influenced structural earthquake are earth damage degree , fault length stress and an angle between extend stress axes and fault strike
研究结果表明，地壳损伤程度、断层长度、应力及拉应力轴与断层走向之间的夹角是影响构造地震的主要因素。
The stress and working pressure on teeth of the staged nut in screw presses has been studied by fem method which proves that using staged nut in screw presses is helpful for improving the non - uniform distribution of stress and working pressure on the teeth and extending the working life of the screw
摘要采用了有限元法对滑动螺旋压力机的阶梯式螺母进行了受力分析，研究了螺母螺牙应力及螺牙工作面的接触压力，并将阶梯式螺母与普通螺母进行对比，认为螺旋压力机中使用阶梯式螺母有利于改善螺牙牙根应力轴向应力分布不均和螺牙工作面的接触压力分布不均的情况，从而提高螺旋工作寿命。
