碳素有效率,Available ratio of soil carbon
effectiveness of soil potassium钾素有效率
3)effective carbon number有效碳数
4)rate of carburization增碳效率
1.Results from tests on carburization in steelmaking indicate that therate of carburization for coal based carhuretant is equal to that for the asphalt based carburetant and substitution of the former for the latter which is widely used will not only have little influence on steel quality, but can also bring noticeable economical benefits to the enterprise.通过炼钢增碳试验表明:煤基增碳剂的增碳效率与沥青基增碳剂相当,用其代替目前普遍使用的沥青基增碳剂炼钢增碳不影响钢的质量,同时可提高企业经济效益。
5)de-carbon-dioxide efficiency除碳效率
6)Carbon humification efficiency投碳效率

配置效率和生产效率在经济学上，经济发展的动力，或者说效率的来源，分为两类：一类是配置效率，二是生产效率。所谓配置效率，是指给定资源和技术的条件下，怎么样使资源从边际生产率低的地方流向边际生产率高的地方，从而使得资源和利用更合理、社会总价值达到最大;而生产效率是指如何通过技术进步提高每一种资源的生产率，也就是把社会的生产可行性边界向外移。
