标题: 一段英文求翻译 [打印本页] 作者: 从不用刀 时间: 2011-10-10 16:38 标题: 一段英文求翻译 the umbilical gulcose uptake is approximately 5 mg/kg/min at normal maternal arterial plasma glucose concentration.because the umbilical glucose-oxygen quotient varies from approximately 0.5 in sheep to 0.8 in human fetuses during labor,it must be assumed that substrates other than glucose(e.g.,lactate,amino acids) fuel a significant amount of fetal oxidative metabolism. Lactate and amino acids may each account for approximately 25% of total fetal VO2.作者: xgw1968 时间: 2012-2-23 20:50
你应该提供原文的复制版本，标点符号也很重要的。看了一下的你文献葡萄糖是Glucose,可惜都写成gulcose了。句子的大意：在孕妇动脉血浆葡萄糖浓度正常时，脐带以大约5mg/kg.min的速度摄取葡萄糖。因为分娩时脐带糖-氧比例不同，大约羊0.5到人类胎儿的0.8，所以必须假定不同于糖（如：乳酸，氨基酸）的底物提供了胎儿氧化代谢很大一部分能量。乳酸和氨基酸也许各自提供总氧供的约25%。
