计算尺是现实被广泛应用的一种快速计算工具。随着工业生产的发展,金属材料试验的专业计算工作就越来越繁重起来。而当前金属材料试验还一直都借用其它类型专业计算尺。因此在算尺板面内容和尺度的安排上都远远不能满足材料试验计算的需要。为此我们按金属材料试验专业计算工作实际所需,试制了“金属材 Slide rule is a fast calculation tool widely used in reality. With the development of industrial production, the professional calculation of metal material testing becomes more and more complicated. The current metal materials test has always been to borrow other types of professional slide rule. Therefore, in terms of the content of the scale board and the scale of the arrangements are far from meeting the needs of material testing calculations. To this end, we calculate the actual work required by the metal material test professional calculations, trial production of "metal
