permanence

Even the permanence of America’s success in Iraq is far from guaranteed..甚至美国在伊拉克的成功的持久性也远未得到保证。

Because, despite the fleeting nature of most of my encounters, and despite my own role in their short duration, I think what I have been seeking in some form from all of these men is permanence..因为，即使大多数和我邂逅的男人们同我只是保持了非常短暂的关系，也无论我在与他们短暂的关系中扮演着什么样的角色，我始终觉得我渴望在这些男人身上得到的是一份持久的关系。

When new or difficult material is presented, almost all listeners are faced with a challenge because human speech lacks the stability and permanence of the printed word..当面对新资料或难度较大的资料时，几乎所有的听众都会面临挑战，因为人类口语缺乏书面文字的稳定性和永久性。
