Actual problems, as they present themselves to the decision-maker, are always concerned with relative efficiencies, and no measure of absolute efficiency is needed.

现实问题，就像是它们呈现在决策制定者面前的那样，总是与相对效率有关，而并不需要对绝对效率的度量。

We also found that the fed-batch can enhance the concentration of thalli and increase the efficiency and the absolute value of transferring se.

实验还表明，分批补料培养可以提高菌体浓度，可使转硒效率和绝对量增加。

In other words, it is a full Systems Approach to earthly resource management, production and distribution, with the goal of absolute efficiency, conservation and sustainability.

换句话说，对于地球资源的管理、生产和分配、伴随着绝对的效率、维护保存和可持续性等，这是一个完整的系统性方式。

In principle, this value, this efficiency, can approach 1 as the low temperature approaches absolute zero.

这个值，效率，当低温热源的温度1,是据对零度时可以达到一。
