as的特殊用法

Many firms ,for instance ,have great difficult in obtaining technical or scientific books from libraries because they are unwilling to have their names entered as having taken out such and such a book
请问as后面加的动名词完成式是什么意思!1起什么作用

1. 这段话本身就有问题.

2. AS 在这里可以理解为 as soon as 或者 when. 后面的从句是主语省略, 变动名词. ... as/when they have taken out such a book. 因为前面主句的主语they 与从句的一样, 在从句里主语(和谓语)就可以省略, 这在语法中叫做 "主谓省略" 或"人称省略".

和前面的unwilling to have their names entered是并列关系 作谓语动词
