Several comparable cases have been reported.But isolated examples do not give an impression of size of the problem-something that can come only from studies of the use or avoidance of foreign-language materials and contacts in different communicative situations.In the English-speaking scientific world,for example,surveys of books and documents consults in libraries and other information agencies have shown that very little foreign-language material is ever consulted.Library requests in the field of science and technology showed that only 13 percent were for foreign language periodicals lead to a similar concussion; the use of foreign-language sources is often found to be as low as 10 percent

有几个类似的案例已经被报道过了.但相互独立的案例并不能说明问题的大小,而只能通过对外语资料使用或避免状况的研究以及对不同交流环境的综合考虑来实现.例如,在使用英语的科学界,调查发现在图书馆和其他信息机构里被查阅的外文书籍和文档非常有限,而图书馆里科学技术类的借书请求里只有13%是针对外文期刊的现象也指向了相同的结论：对于外文资源的使用常常被发现低至10%.
语言障碍范围的证据来自于对科学界所使用的书籍、期刊等材料的 _____ .
PS:原文有些错误,例如最后一排的concussion应该是conclusion.
