permanence

永久, 持久中释n

1 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。

2 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。

3 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。
