四倍地

On the top500.org list of the world's fastest computers, the bottom-ranked machine has a performance of 851 gigaflops.

这个星期讨论的原型细胞芯片的主频将高达256G，比现在最快的桌面台式机性能高出十倍左右，因此细胞芯片被广泛地称为&芯片上的超级计算机&，这么说有点夸张，但不算过分，在top500.org世界最快计算机名单上，最慢的计算机的性能是851G，由仅仅四个细胞芯片构成的计算机的性能将轻易超过这台机器。

The prototype Cell being discussed this week runs at 256 gigaflops (a flop—one "floating-point" operation per second—is a measure of how fast a processor can perform the individual operations of digital arithmetic that all computing ultimately boils down to). A speed of 256 gigaflops is around ten times the performance of the chips found in the fastest desktop PCs today; the Cell is thus widely referred to as a "supercomputer on a chip", which is an exaggeration, but not much of one. On the top500.org list of the world's fastest computers, the bottom-ranked machine has a performance of 851 gigaflops. A machine based on only four Cell chips would easily outrank this.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
