科技写作中经常会用名词来作为形容词使用，如 room temperature, university researchers. 当用一个 名词来修饰另一个名词时， 意义一般都很 清楚 . 但当三个名词 放 在一起， 或两个名词前再加一个形容词时， 就要小心 . 有的情况 下 , 3 个或 3 个 以上的名词放在一起， 表达的意思很清楚， 也是一种很简洁的表达方式 . 如 : blood white cell number, prostate cancer patient, Beijing University medical school student. 但有时会有多种讲法 . Top university researchers 可以是 researchers of (only) top university 也可以是 (all) university researchers who are top. 多个名词排在一起， 即使表达明确， 也给拥挤的感觉 . 应避免使用多个名词的修饰方式 . 最好的办法是用介词或其它方式来把他 们分开 , 以便清楚表达它们的修饰关系 . 多个名词罗列的情况经常发生， 下面 多举一些 例子 .
