摘要
为了对熟练地应用工程参数,引入优先数系的有关知识,给出了常用公称尺寸系列的内在关系,通过首数与系数的数学关系,即可快速算出参数序列,这些参数就会"存储"在我们的大脑中,方便了设计中的应用。
In order to apply skillfully engineering parameters, the priority number system knowledge is draw-in, inherent relationship of engineering parameter is given, numerical series can be calculated though relationship between the first and the coefficient, engineering parameter may be saved easily in our brain, the application in designing process will be convenient.
