Hockney的用法和樣例：
例句
用作名詞 (n.)
- My finding about the unlikely focal length of the putative projection mirror has a second implication, even more constraining to the Hockney theory.
既然設想中投射鏡的焦距不太可能實現，我的發現還延伸出第二個推論，更使霍克尼的理論受限。 - Given the surviving records for all manner of other optical systems and mechanical drawing aids, the absence of evidence for the Hockney projector is difficult to explain.
其他光學系統與繪圖輔助工具的記錄，到今天都還留存了不少，為何唯獨缺乏霍克尼投影設備的證據，顯然很難解釋。
