Finally, optical fiber lifetime is estimated and the lifetime design picture of optical fiber which passed three-grades proof testing strain is given.

最后，对筛选试验后的光纤寿命进行了估算，给出了光纤经三个等级的筛选应变后的寿命设计图。

The bottom line here is the more fiber you eat, perhaps, a lower level of hormone in your body, and therefore, a lower lifetime risk of developing breast cancer.

在这里最重要的一点是，你吃的纤维越多，可能你体内的激素水平就越低，因此一生当中患乳腺癌的风险就越低。

The analysis shows that it is important to obtain stable self—pulses by changing the photon lifetime of two orthogonal polarization modes in the erbium —doped fiber laser.

结果表明，掺铒光纤激光器中两正交偏振模光子寿命的调节对获得稳定的自脉冲有着十分重要的作用。
