The definition of Q rates of convergence in iterative algorithms is extened and the efficiency measure is developed.

推广了迭代算法收敛分析中的Q 收敛阶的概念，据此给出了算法效率的一种一般的度量。

Outfitting the apartment building with a solar thermal system of ten vacuum-tube collectors for the central domestic water supply is an additional energy efficiency measure.

舾装公寓大楼和一个太阳能热系统的真空管集热器十中央家庭供水是一个额外的能量效率的措施。

And then we're going to turn to the question of efficiency. How do we measure efficiency of algorithms? Which is going to be a really important thing that we want to deal with, and we'll start it today, it's undoubtedly going to take us a couple more lectures to finish it off.

然后我们会回头继续讨论效率问题,我们如何计算算法的效率？,我们处理这些问题的时候,最重要的事情是什么？,我们今天要去讨论这个问题，毫无疑问我们要用,挺多节课来学习这个。

OK. So to do this, we need a little more abstract way of talking about efficiency, and so, the question is, how do we think about efficiency? Typically there's two things we want to measure.

好，为了达到这个目的,我们需要用一种有点，抽象的方式去讨论效率，这衍生出来,一个问题，我们该怎么去认识效率？,主要来说我们有两个要量化的东西。

Because the drive generates this power at a time distinct from when the motor is running, it should not be considered an energy efficiency measure.

Ofgem said two separate schemes ensured that more than 3.9 million lofts and 2.5 million cavity walls were insulated, and 150, 000 vulnerable households received at least one energy efficiency measure by the end of 2012.

Portman said he finds it hard to believe that a couple of "rogue agents" in Cincinnati were responsible for the conservative targeting and that it was done as an efficiency measure to handle a large number of applications, as was initially suggested.
