For example, traditionally most museums have had permanent collections built around a specific theme. But very often their artifacts are far removed from their places of origin, cutting off their connection to their original environment, thereby obscuring much of their contextual meaning.
譬如，大多數的博物館均根據其特性選擇永久性的藏品，卻往往把文物帶離它們的原產地，以致割斷了它們與環境的關係，和它在環境中的意義。
