We used a concept called nutrient density to determine which foods have the highest nutritional value.
我们用一个叫做营养物浓度的概念来衡量最具营养价值的食物。
Foods with a high nutrient density are foods that contribute a high percentage of the nutrients In relation to the calories provided.
高营养密度食物提供营养素的百分率比能量供给百分率高。
Phosphorus is the first limiting nutrient density to the algae populations, and therefore control the eutrophication, may depend on the phosphorus control measures.
磷是水体中藻类种群和密度的第一限制性营养元素，因此在水体富营养化的治理上，可能取决于对磷的控制措施。
It is also important to note that, unless a high nutrient density diet is fed post-weaning, the benefits that arise from having a heavy pig at birth are lost (Lawlor et al., 2002a).
同样重要的是要注意，除非在断奶后饲喂高营养密度的日粮，初生重大的优势可能会丢失(劳勒等人，2002年)。
The results showed: the nutrient cycling was different among the different planting density of C. cajan, but the efficiency of nutrient utilization was same among the different planting densities .
结果表明，不同种植密度下林分的营养循环表现出了一定的差异性，而养分的利用效率则一样。
The standing nutrient accumulation in whole stand increased with the increase of density.
林分营养元素积累量随林分密度的增加而增加；
The standing nutrient accumulation in whole stand increased with the increase of density.
