Surprisingly, this is computationally tractable, because our energy functions are sums over pairs of interactions.(令人惊奇的是，这在计算上是易进行的，因为我们的能量函数是很多对相互作用的总和。)
To make both problems tractable, we have the assumption that each sensor node keeps working since it turns on.(为了使问题可解，我们假定每个节点在开启后将一直保持工作状态。)
Let us see, those who have families must be tractable, and shake hands with us and take themselves off, and leave us here alone to attend to this affair.(那些有家室的人要发发善心，乖乖地来和我们握手，然后离开这里，让我们安心工作。)

It is now accepted that the tree of life is something we impose on nature in an attempt to make the task of understanding it more tractable.(现在大家认为，生命之树是人类试图使理解大自然这件差事更易驾驭而强加给自然界的有价值的事物。)
Finally, there is the delight of working in such a tractable medium.(最后，乐趣还来自于工作在如此易于驾驭的介质上。)
Typically, decision problems require making some sorts of assumptions about the state of the world to be at all tractable.(通常来说，决策问题需要根据世界的状态作出一些假设，并使它们易于处理。)
