能帮忙翻译一下意思吗？我看不太懂。。

ahasusanna

sunspot cycle太阳黑子周期
the rate at which trees grow  is believed to be among the surest indications on Earth of sunspot cycles
是为了让 their trunks指代没有歧义才把the rate at which trees grow放在后面的
人们相信，树木生长的速度是地球上最确定的太阳黑子周期的征兆之一，这可以从树干横截面上可见的年轮看出来
不知道我有没有说清楚

as seen in the 的as是怎么个用法？

个人意见：
seen in...过去分词作定语，非限定性的修饰前面的主语rate，as在其前面做副词，表示“像。。一样”，连起来就是像在。。中看到的一样
举个有道里的例句：Thelaw ，as seen intheOld Testament ，oftenleavesus with a feeling of guiltandfailure.——旧约的律法只会让我们停留在罪咎和失败中。
原谅我之前的乱七八糟的什么方式状语从句省略的解释吧。。已经编辑掉了。。是我大半夜犯迷糊了。。
