1. The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company.
这些关系的复杂性使得进口救济法体系不能满足相同母公司下所有子公司的的战略需求。
2. Our first studies sought to determine whether the increase in serotonin observed in rats given a large injection of the amino acid tryptophan might also occur after rats ate meals that change tryptophan levels in the blood.
据留学360介绍，在我们的第一个研究中，我们给老鼠注射了大剂量的aat物质后，发现它的s物质含量上升了。我们想确定如果给老鼠吃那些能够改变其血液中的t物质含量的食物，同样的现象是否会出现。
3. The more protein in the meal, the lower is the ratio of the resulting blood-tryptophan concentration to the concentration of competing amino acids, and the more slowly is tryptophan provided to the brain. Thus the more protein in a meal, the less serotonin subsequently produced and released.
食物中的P越多，血液中t的浓度和aa的浓度比越低，t被供给大脑的速度也就越慢。所以，食物中的P越多，S的产生和释放的就越少。
4. The explanation they consider most plausible is behavioral differences between extinct and present-day carnivores—in particular, more contact between the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct species.
据留学360介绍，他们认为最合理的解释就是灭绝的食肉动物和现今的食肉动物之间的行为差异，即捕食者的牙齿和猎物骨头之间的接触，因为捕食者要将猎物吃的很干净。
