我用google搜寻summary、summation的差异

但这段还是看不太懂：
As nouns the difference between summary and summation is that summary is an
abstract or a condensed presentation of the substance of a body of material
while summation is a summarization.
As nouns the difference between summary and summation is that summary is an
abstract or a condensed presentation->到这边都看得懂
of the substance of a body of material->加上这句就看不懂了...
跪求高手解析一下这边一堆of是在of什么== (只知道是在修饰condensed presentation?
summation is a summarization. 这个子句更是看得雾煞煞== 什么叫做总结就是总结?
求好心人解答QQ 100P酬谢

of a body of material 意思是书或文章的正文部分所以of the substance of a body of material 意思就是

一次看一个of就知道他的意思了，只是写得比较囉嗦

书或文章正文的要旨。

summarize表示做结论的动作，而名词化(nominalization)之后就是指这个动作的行为本身(为一个名词)，所以summation就是指做结论的行为本身，不过语俗或我自己也不太会用这边的意思就是了，它也可作抽象/实际的总和

谢谢两位大大，下班再发P币，所以summation跟summarization两个字可以互相替换，一模一样的意思？

summation和 summarization不能替换啊 一个是结论，一个是“下结论”这个动作。舞跟跳舞会一样吗?
