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。

Using servo control system, the length and width of cloth to 1 mm with absolute precision square shape is more perfect, sealing side, the efficiency is greatly improved.

使用伺服控制系统， 布料宽度与长度的到达1毫米的精确与外形绝对的四方形﹑封边更完美﹑效率大大提高。

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。
