We must not only focus on the construction of energy-efficient to reduce energy use, but also must consider as a low quality (moronity value of the conversion rate) energy.

建筑节能不仅要着眼于减少能源的使用，也必须考虑尽量采用低品质(低能值转换率)的能源。

The improved frequency conversion timing system not only reduces working strength of the labor and improves timing accuracy, but also reduces failure rate and energy consummation.

改造后的变频调速系统不仅减轻了工人的劳动强度，提高了调速精度，而且故障率低，降低了能耗。

The results indicate that the growth rate of perturbation is proportional to that of the energy conversion.

结果表明，扰动的增长率正比于基本流与扰动间的动能转换率。

Most of the challenge, as we often see for solar cells, is just a matter of improving the energy conversion rate.

ENGADGET: All-carbon solar cell draws power from near-infrared light, our energy future is literally that much brighter
