The allowable stress number, load, geometry parameters and life have the most significant effects on pitting resistance rating results; 试验齿轮的应力修正系数、载荷和几何参数对弯曲强度计算结果的影响较大。
It was shown that the cumulative plastic strain depended not only on the applied cyclic stress and number of cycles, but also on the initial static deviatoric stress level. 在上海地区典型饱和软粘土不排水循环三轴试验的基础上,分析了影响软粘土塑性累积变形的主要因素:循环荷载的作用次数,初始静偏应力和循环加载动偏应力。
The concepts of stress complex number and strain complex number and inertia complex number are presented in this paper. 文章提出应力复数、应变复数和惯性复数的概念,得到一个复数方程式,即复数莫尔圆方程。
This paper has put forward the new method determining the design criterions of en - closed gear drive by equal stress tooth number and solved the question without repeating design. 提出了按等强齿数确定闭式齿轮传动设计准则的新方法.解决了齿轮传动设计的试算问题;
Feulgen staining showed that under low-phosphorus stress the number of lateral root primordia was significantly reduced; and statistical results showed that the treatment of low phosphorus decreased the number of lateral roots. 福尔根染色表明低磷胁迫下齐319侧根原基数目显著减少;低磷处理下齐319侧根数目也明显少于对照。
