The vegetaive organs of Hippophae rhamnoies were studied The results showed that the primary xylem of its stem ane leaf has shield-like hair, The small leaf and thick cuticle have close relation with its drought-resistant.

Advances on conversion of lignocellulosic biomass to ethanol by SSF process.;

The properties of as-spun fibers and precursors were decreased when those parameters were lower or higher than the .

The results showed that the coagulation bath composition had little influence on the size of the internal micropores in the fibers, and the fibrillation of as-spun fibers occurred in a slight degree during the spinning process.

The effects of acid content of coagulation bath and PANI content of spin dope on the morphology and structure of as-spun fibers were studied by SEM.

Discussion of influential factors on the orientation and properties of PAN nascent fibers

The paper was mainly studied the effect of coagulation bath drawing action on the solvent diffusion coeffecient and property of nascent fibers during the polyacrylonitrile wet spinning.
