在我们选择了帆船模型的图纸和类型以后,必然要选择模型的比例。众所周知,船模的比例,其实质就是你所建造的船模比真船缩小的程度。举例来说,1:50的比例意味着模型的尺度只有真船的五十分之一。图纸比例和模型比例的概念是一个分数的概念,其含义在工程技术上是约定俗成的,并为各国的国家标准和国际标准所明文规定了的。 After we have selected the drawings and types of sailing model, we must choose the proportion of the model. As we all know, the proportion of ship models, in essence, is the extent to which you build a ship model that is smaller than a real ship. For example, a 1:50 ratio means that the scale of the model is only one-fiftieth the size of a real ship. The notion of drawing proportions and model proportions is a concept of fractions whose meaning is conventionally established in engineering technology and which is expressly set forth for national and international standards in various countries.
