定语从句 什么时候可以省略先行词
The mathematical model 【which was】recommended by Britain’s National Radiological Protection Board (NRPB) predicted that the screening programme would cause 36 cancers per 100,000 women,18 of them fatal
我知道指代宾语的关系代词可以省略,但像上句中【】里也可以省略,我就看不懂了,不知道什么时候可以省略关系代词(副词)?

这里不是定语从句,而是:过去分词作定语
单个过去分词作定语,通常前置,具有被动和完成的意思
例:the broken cup = the cup which is broken
一个摔破的杯子
过去分词短语作定语,通常后置,作用相当于定语从句
例:The cup broken by him had been used for 10 years.
他打碎的那个杯子已经用了10年了.
这里它同样指代宾语,只是从句部分用了被动句形势,我想你可能以为它指代的是主语了。
所以说指代宾语的关系代词可以省略
关系代词在定语从句中做宾语时可以省略,但这不是定语从句而是过去分词短语作后置定语,作用相当于一个定语从句。
