波美度糖度比重?fù)Q算表

1、相對(duì)密度和波美度的測(cè)定相對(duì)密度是液體一個(gè)重要的物理常數(shù)。利用密度的測(cè)定可以區(qū)分化學(xué)組成相類似而密 度不同的液體化合物、鑒定液體化合物的純度以及定量分析溶液的濃度。由于測(cè)定密度比較麻煩，也不易準(zhǔn)確。因而常采用測(cè)定相對(duì)密度予以代替。波美度是量度液體相對(duì)密度的另一種標(biāo)度，符號(hào)為oBeo由18世紀(jì)法國(guó)科學(xué)家波美所 創(chuàng)制的，因此這種比重計(jì)叫做波美比重計(jì)。波美比重計(jì)有重表和輕表兩種。重表刻度的方法是把15oC的純水的相對(duì)密度作為0oBeo 0%食鹽水溶液的相對(duì)密度作為10oBe波美度與比重?fù)Q算方法:波美度=144.3-（144.3/比重）;比重=144.3/（144.3- 波美度）對(duì)于比水輕的：比重=14
