Under lower cyclic stresses, the fatigue cyclestofailure in vacuum is increased 2 or 3 times.
在低循环应力时,真空环境中的疲劳断裂次数可比室温大气环境中的多2至3倍。

Under lower cyclic stresses, the fatigue cyclestofailure in vacuum is increased approximately 4 times than in air.
在低循环应力时,真空环境中的疲劳断裂次数可比室温大气环境中的高近4倍。

And the range of cyclic loads that single bucket foundation can be subjected has been determined under certain static loads for 1000 number of cyclestofailure.
