在工作或学习中,常常会碰到一些科技名词或术语使你困惑。有些名词尽管常见、常写,或知道其中的大概,但细究起来却又茫然。例如,在建筑材料行业中,什么是“水泥”、“胶凝材料”、“胶结料”、“水泥熟料”,你能说出它们确切的科学定义吗?什么叫“粉尘”、“烟尘”、“微尘”、“飘尘”,你能说出区别它们的界限吗?因此,不论是谁,要想把工作做好,就必须随时翻阅一些书籍,而辞典是一种解惑释疑的最好的工具书之一。 When working or studying, you often encounter technical terms or terminology that puzzle you. Although some nouns are common, often written, or they are known to some extent, they have been evasive when examined in detail. For example, in the building materials industry, what are the “cement”, “gelling material”, “binder”, and “cement clinker”. Can you name their exact scientific definition? What is “dust” and “smoke? ”Dust,“ ”flying dust," can you tell the difference between them? Therefore, regardless of whoever wants to do a good job, you must always read a few books, and the dictionary is a solution to doubts and doubts. One of the best tool books.
