專業(yè)釋義

化學

• 取代度

  The behaviour of starch is different even if it has the same resources and the same modified methods when its degree of substitution is different .
  大量的研究表明；淀粉的來源不同，使用相同的變性方法，淀粉的性質不同；而且淀粉的來源相同，變性方法也相同，但取代度不同，其性質也將會千差萬別；至于變性方法不同，變性的物質不同那就更不言而語了。

  機械工程

• 取代度

  After OSA modification,the degree of substitution was 0.012 40.019 4. Photomicrographs by scanning electron microscopy revealed that OSA groups acted by attacking the surface and some hollows formed.
  該工藝所制備的小麥辛烯基琥珀酸淀粉酯的取代度為0.012 40.019 4。
