金属材料的重量计算经常会遇到,一般是在相应的手册中,通过查表的方法直接查出。例如在实用五金手册及其他机械加工手册中,均有根据金属的尺寸换算出重量的表。但在查表时,往往需要花费很多时间,尤其在资料缺乏的条件下,重量的计算就感到不便和困难。我根据多年来的工作经验,找出列表换算的规律,归纳成利用经验公式计算的方法。只要记住公式和系 The weight of metal materials often encountered, usually in the corresponding manual, through the method of table lookup directly. For example, in the practical hardware manual and other machining manuals, there is a table that converts the weight according to the size of the metal. However, when looking up a watch, it often takes a lot of time. Especially in the absence of information, weight calculation is inconvenient and difficult. I based on years of work experience, to find out the rules of the list conversion, summarized into the use of empirical formula method. Just remember formulas and lines
