Of course, not every cluster covers a major part of a particular value chain or is characterized by a sound, self-sustained institutional basis.

当然，不是每一个集群都包含特殊价值链的主要部分或者有健全的、自我维持的制度基础的特征。

Also, it's totally self-sustained, thanks to a solar energy and hydrogen fuel cell combo, and it doesn't require any kind of input from the ground.

此外，由于有太阳能电源以及氢能源电池组，它完全能够自给自足而不需要任何形式的地面电能补给。

While housing markets continue to lag, providing one of the largest obstacles for a self-sustained economic recovery, The Home Depot, one of the largest home repair retailers, posted a 12% surge in profits despite falling sales.

And with recent natural catastrophes proving atomic energy isn't what you'd call 'safe, ' it's a good thing the researchers down at the RMIT University in Melbourne have been hard at work figuring out how to turn you into a self-sustained energy source.

And that way the expansion then becomes more self-generating and sustained, and perhaps to some extent makes believers out of even those who sort of argued against the fact that it would continue, and certainly, I think, put to rest any talk of double dips.
