用指数函数对波浪和海冰作用下平台构件的疲劳应力、应力循环次数和环境参数的关系进行了拟合，拟合精度很好。
The exponential functions were used to reflect the relationship among fatigue stress, number of stress cycles and environmental parameters. The fitting precision of the functions was relatively high.
应力越高，在可以预料的破坏之前循环次数就越少。
The higher the stress the fewer will be the cycles before failure can be expected.
当应力大于应力阈值时，氢化物应力再取向程度随着与应力、温度循环次数增加而增大。
When applied stress is higher than the threshold stress, the level of hydride reorientation increases with the increase of stress and the number of temperature cycling.
