For example, he says, when rescue teams in American cities arrive at a collapsed building, at the touch of a computer key they can consult the building's complete structural drawings, and see exactly where the bedrooms, stairwells and service ducts are, to assist their search.
他舉例，美國城市搜救隊每到達一棟倒塌建築時，只要在電腦上按一個鍵，就可以調閱出這棟建築完整的結構圖，那裡是臥室、樓梯間、管線間，一目了然，方便搜救。
