[求助] 请帮助翻译一小段英语

这是一篇英文文献中的一段关于数据分析的,自己看起来很生涩难懂,请高人翻译成比较容易明白的中文。谢谢
  Statistical Evaluations.:A MIXED procedure of the SAS system
was used to analyze data from the storage studies (21). Means were separated using the p-diff test. For each treatment, two or three separate reactions were examined during storage. Because a subsample was removed from each reaction vessel at each time point, repeated measures were used. Analysis of repeated measures data requires special attention to the covariance structure due to the sequential nature of the data on each experimental unit 。The mixed model allows the capability to address the issue directly by modeling the covariance structure. The variation between separate vessels within a treatment is specified by a
“random” statement in the model. The covariation within a vessel is specified by a “repeated” statement in the model. The covariance structure that was fitted in the model was the spatial power matrix. This was used because the distance between each time point assayed was in some cases not equivalent. Standard deviations are reported。

统计评价: SAS系统的混合过程。被用来分析存储研究的数据(21) 。使用P- diff的测试手段进行分离。每次处理,研究了贮存过程中的两个或三个分离反应。因为一个子样本是在每个时间点从每个的反应容器中取的,且重复测试。分析重复测量的数据,需要特别注意由于各试验单位的数据的连续性引起的协方差结构。混合模型有能力直接解决问题通过协方差结构建模。在一个处理期内,单独的容量之间的变异是通过一个    确定的模型中的“随机”的声明。模型中的“反复”声明的是指定的范围内的容量共变。模型中安装的协方差结构是空间功率矩阵。这是用来检测各时间点之间的距离,因为在某些情况下,他们不相标准偏差已报告。

不专业的翻译,给你参考一下句型结构吧。嘿嘿
如若这般,当初又为了什么?
