1) water supply efficiency
供水效率
1.
The results show that,as for the same irrigation amount,tuber initiation and bulking stages are the stages of complementary irrigation with the most yield increase and water supply efficiency;using different irrigation amount at the tuber initiation stage,both the yield and water supply efficiency are the largest under the irrigation amount of 3 or 4kg per time per plant.
结果表明:以相同补水量在不同生育时期实施补灌,以块茎形成期和块茎增长期供水效率和产量最大;在块茎形成期以不同补水量实施补灌,在同时满足供水效率最高和产量最大的前提下,以3~4 kg/株的补灌量较适宜。

实验研究了高温空气燃烧系统使用的蜂巢蓄热体热回收率、最佳换向时间、流动阻力等性能参数及其随几何尺寸的变化规律;提出供风效率的概念,表征流经蓄热体的实际供风量与总供风量的差别,并对热回收率进行了修正。
补充资料：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。
