在60岁左右,“肌肉真的开始分解,”一位研究衰老的研究员凯瑟琳·斯塔尔说,“也正因为如此,老年人对蛋白质的需求实际上增加了。”
At around age 60, "muscles really start to break down," say Kathryn Starr, an aging researcher, "and because of that, the protein needs of an older adult actually increase."
您现在可以使用流程分解结构来驱动需求指定的方式。
You can now use the process decomposition structure to drive how requirements are specified.
