它们起先是小泡然后变成纤维管。

这样，当有光照射到材料上并激发激子后，所有激子将流向在纤维管的中心并在此集中。

Therefore, when light energy strikes the material, all of the excitons flow to the center of the fiber, where they are concentrated.

用多孔、中空纤维管复合多种细胞外基质和雪旺细胞，有显著促进神经再生作用。

It can be significantly promote nerve regeneration used porous hollow fiber tube composite with various extracellular matrix and Schwann s cells.
