中文摘要：
在分析组织结构并测定脂肪含量的基础上，利用现代制革鞣制工艺对一头小布氏鲸（Balaenoptera edeni）的皮作了脱脂效果研究。在控制好对皮肤整体质量影响最小的情况下，本文设计了一套工艺流程，将脱脂操作贯穿到整个皮张的鞣制过程中。经组织切片和氯仿甲醇法检验，胸部和腹部真皮的脂肪体积比，由31．78％±2．69％和44．80％±3．74％下降至4．28％和6．83％；含脂量下降至4．04％和5．57％，脱脂率达到了86．24％和84．90％，基本满足了标本制作的脱脂要求。
英文摘要：
The degreasing effect of leather tanning process on one Bryde＇ s Whale, Balaenoptera edeni, skin was evaluated by the adipose content and histological structure. The thiekness of derma was varied from 15 to 35 mm at different part with 2.3 times between most and least thickness. The tail contained a few elastic fibers, while the rest of derma were constructed with collagen fiber at 1.08 ± 0.25 μm （ n = 180） in diameter and those collagen fiber was arranged in a loose reticulation. Adipose cell filled between the collagen fibers and the contents of skin adipose in throat, chest, abdomen and tail were 19.42% , 29.36% , 36.89% and 13.06% , respectively and showed a significant difference （P 〈 0.01 ） between different parts. In this study the leather was treated throughout a special designed tanning process of degreasing operation at the requirement of minimizing impacts on the skin＇ s quality. The volume proportion of skin adipose in chest and abdomen was reduced from 31.78% ± 2.69% and 44.80% ± 3.74% to 4.28% and 6. 83% measured by chloroform- methanol method; adipose contents in chest and abdomen were reduced to 4.04% and 5.57%. The overall degreasing rates were up to 86.24% and 84.90% , which was fit with the requirement of making a specimen.
