We find that the tone-on-tone effects of the medullated and dead wool to the normal wool is good.

实验证明此工艺可以明显改善粗腔毛、死毛与正常羊毛的染色同色性，取得较好的染色效果。

The article introduces the factors of the medullated and dead wool and the effects for dyeing gets.

文章介绍了粗腔毛、死毛的成因及影响其染色性能的机理。

Observation with transmission electron microscope: There were regeneration medullated nerve fibers in myoblast group and extracellular matrix gel group.

透射电镜观察：成肌细胞组和细胞外基质凝胶组均见再生的有髓神经纤维。

Result:The regenerated nerves of decimeter wave sides had more medullated fibers, larger mean axons diameters and thicker myelin sheath than those of control sides.

结果：与对照组相比，实验组再生有髓神经纤维数目较多、轴突较粗且髓鞘较厚。
