The results showed that tensile strength, tensile yield stress and tensile breakingstress were increased with the increase of bore distance;
结果表明，随筛板孔距的增加，其拉伸强度、拉伸屈服应力及拉伸断裂应力均提高；

All things being equal, which they rarely are, the higher the cyclical stress level on an aircraft structure, the fewer the number of reversals it can withstand before breaking.
所有的事情很少是平等的，飞机结构上的周期性压力水平更高，破碎前它可以承受倒转的数字就更少些。

When he plugged that wind-force equation into his model and assumed that the probability of a branch breaking due to wind stress is constant, he came up with Leonardo's rule.
