求老师帮忙回复一句专家审稿意见

　　求老师帮忙回复一句专家审稿意见。were taken randomly every 6 days (from each temperature?)
What does it mean?

其中(from each temperature?)是在论文写作时候导师自己加进去问我的，结果我的时候没发现就没删除投出去了，现在审稿人问(from each temperature?)是什么意思，我该如何回复呢？英语不太好，求高人帮忙写一两句，谢谢！！！
===有问必答===
改成for
解释就说是每个温度都是这样的

或者去掉这个，就说是笔误

楼主有做温度梯度吧，导师的本意是每个温度梯度都取样么，去了或者充实写清楚

This phrase should be deleted form the manuscript. Im sorry for the mistake and thanks for your patience.
