请帮我分析一下以下这个句子的结构.
we first verify the clinical efficacy of 补肾祛毒汤.and then certify the mechanism,by the modern research methods that observing the treatment effect of curing the CRF rats modeled-by-adenine with 补肾祛毒汤.
其中“,by the modern research methods that observing the treatment effect of curing the CRF rats modeled-by-adenine with 补肾祛毒汤.” 是什么结构?“observing”的时态在这里用的对吗,为什么?

by the modern research methods that observing the treatment effect of curing the CRF rats modeled-by-adenine with 补肾祛毒汤 (补肾祛毒汤?什么东东?)
首先,by在这里引导的是一个方式状语,其中又包含了一个由that引导的定语从句.
其次,“observing”的时态在这里用的不对.that在这里指代的是前面的 the modern research methods ,后面的从句需要是个完整的句子.所以这里应该用动词原型observe,
that后面跟个动名词,我觉得不对啊
肯定不是时态,因为缺少be。
把 that observing改成 that observe或者observing,就对了
1.做状语
2.用法对
