| 摘 要： | 论述了灼烧恒质在饲料粗灰分测定中的作用和影响，饲料只有在灼烧至恒质时，才能将饲料中的有机成分完全氧化为无机灰分，从而加以准确测定。此外，也研究了灼烧温度、灼烧时间、灼烧坩埚大小、饲料样品的称样量对饲料粗灰分测定的影响。

| Abstract: | Effect and influence of ignition to constant weight on the determination of feed crude ash was discussed.Only when feed ignited to constant weight,could the organic ingredient oxidate completely into inorganic ash,and so the exact result could be got.Moreover,the influence of many factors on the determination of the feed crush ash,such as ignition temperature,ignition time,the size of the crucible and weight of the feed sample was studied. |
