如果将关注食物链顶端和底端的方法同时应用到全球性数据上,那么,科学家们得出的结论是,过去10年的工业捕渔更偏向捕食低食物链鱼类,而对高食物链等级的鱼类而言,它们的食物总量减少了将近一半,倘若按照食物链理论的逻辑,现存高食物链等级的鱼类总数是增加了而不是减少了,因此,不能够简单地认为,工业“捕渔”导致鱼类总体的数量减少。
Applying both methods to worldwide data, the scientists say industrial fishing over the past decades has not simply worked its way downwards from the top of the food chain -- it has gone upwards, too.
要完成这项任务,我们将取得在一个时间间隔中使用的总体CPU时间,然后用该时间间隔中15分钟活动用户总数除以它。
To do this, we will take the total CPU used in an interval and divide it by the total active 15-minutes users in that interval.
方法和结果: 基于2002-2004英国实践研究总数据库(GPRD)的总体性队列研究, 其中包括首次AMI后生存90天病人…
Methods and results: Population-based, cohort study, from 2002 through 2004 in the United Kingdom General Practice Research Database (GPRD), involving patients surviving 90 days after their first AMI.
