| 引進(jìn)產(chǎn)品圖樣中英制單位換算問題的探討(36 卷) |
| 英文標(biāo)題 |
| Discussion on the Conversion of British System Measurement Units in the Imported Products’ Designs |
| 摘要 |
| 在技術(shù)引進(jìn)中，對(duì)線性尺寸為英寸表示的產(chǎn)品圖樣，用換算式1 in=25.4 mm換算后，得到的小數(shù)位往往超過原英寸小數(shù)位要求的精確值。為此，就如何解決圖樣中公差尺寸、形位公差尺寸及一般公差尺寸的英寸轉(zhuǎn)換為毫米后的數(shù)值修約問題做一探討。 |
