,which 语法but not that porosity is not the same as the permeability,which measures the ease with which water can flow through a material.能不能讲解一下这句which修饰那个,怎么理解,是什么句式啊?
The proportion of empty space in a rock is known as its porosity. But note that porosity is not the same as permeability, which measures the ease with which water can flow through a material; this depends on the sizes of the individual cavities and the crevices linking them.
空隙在岩石中所占的比率称孔隙率.但要注意孔隙率和渗透性不是同一概念,后者用来测量水流经某材料时的容易度,这取决于单个腔体和连接它们的缝隙的大小.
析：第一个which是关系代词,指代的先行词是permeability, 引导非限制性定语从句（至material), 对permeability进行解释（定义）.而with which 是引导限制性定语从句的介词+关系代词, which指代的是the ease,

注：porosity
The ratio of the volume of all the pores in a material to the volume of the whole.
孔隙率：一材料中孔隙的总体积与整个材料的体积之间的比率
permeability,
1.
The property or condition of being permeable.
渗透,渗透性：可渗透的特质或状态
2.
The rate of flow of a liquid or gas through a porous material.
渗透度,渗透率：液体或气体通过渗透材料流的量度

PS:你的note误打成not,引起理解句意的困难.

两个都是which引导的定语从句
第一个which修饰permeability
第二个是with+which修饰ease

是which引导的非限制性定语从句，修饰permeability

翻译：最终他被允许可以发一份传真来告诉编辑他已经被捕了。用IN主要是要看从句中的意思，WHICH这里指代的是FAX里讲的内容，如果把WHICH　去掉，我们可以看从句如下：in　the　fax　he　informed　the　editor◆hat　he　had　been　arrested．　这里用　IN主要是指代的是FAX的内容，比如我们常说in　the　news　paper－新闻报纸里报道．．．．－－而不用其他的介词搭配628《这里一般会让人联想到另外一个语法的：IN　THE　PAPER（指纸里面写的内容）　和　ON　THE　PAPER　（指放在纸上面的东西）的区别》这类由IN　WHICH49　ON　WHICH173　BY　WHICH从句的搭配关系5173主要是要看从句的谓语和介词的搭配或状语里的介词和名词搭配cgk　其实我觉得所有的从句，无论是主语从句，定语从句，宾语从句还是状语从句，其实都是一样的，主要是从句在主句里的位置不同而叫法不同而已nr从句跟主句之间的介代词搭配主要还是看从句。有的复杂的句子有好几个从句，其实做法也简单，把他们按不同的从句分开，然后再逐一分析，解决起来也就容易多了。以上是我的理解，　希望对你有帮助。
