1)  energy and nitrogen balance
能氮平衡
2)  rumen energy-nitrogen balance
瘤胃能氮平衡
1.
The rumen energy-nitrogen balance principle was briefly introduced and the rumen energy-nitrogen balance situations under condition of typical “straw plus mixed meal” ration in our countryside were analyzed.
简介了瘤胃能氮平衡原理,分析了我国农村典型的“秸秆杂粕”日粮条件下的瘤胃能氮平衡状况,认为瘤胃能量供应不足,即瘤胃能氮负平衡是影响此种日粮条件下泌乳牛生产性能的限制因素。

6)  Ammonia nitrogen balance
氨氮平衡
补充资料:氨合成平衡速率氨平衡合成率
分子式:
CAS号:

性质:又称氨合成平衡速率氨平衡合成率。在不同的催化反应条件下,氨合成反应达到一定程度的化学平衡时氨合成的反应率或合成率。在实际氨合成生产中,不可能达到平衡氨合成率,在工业上设计氨合成塔时,就必须着眼于它的运行能最大限度地接近平衡氨合成率。
