载能体

氢是理想的载能体，是用于燃料电池和内燃机的理想清洁燃料。

Hydrogen is an ideal energy carrier that can be used as an essential clean fuel form .

氢是一种十分理想的载能体，它具有能量密度高，热转化效率高，清洁无污染等优点。

As an ideal energy carrier , Hydrogen has advantages of high energy density , high convert efficiency and cleanness .

随着全球大气温室效应问题日益严峻，在未来的可持续能源系统中，氢有望成为重要的载能体。

With the problem of greenhouse effect becoming serious , hydrogen is hoped to be an important carrier of energy in the future continuable energy system .

但随着载能体概念的提出，以及系统节能技术的推广使用，人们感到用产品能耗指标来评价钢铁生产过程用能的合理程度似乎更具有科学性。

With emerging of the idea of energy carrier and extended application of systematical energy-saving technology , however , people become aware that it seems more scientific using product energy consumption indexes to appraise reasonable level of energy use in iron and steel production .
