| Abstract: | It is recommended that Cr_m/r_c)~2- 1] can be used to express the denseness of the structure of precipitation fibres. The reliability of this method is confirmed by means of the measurement of swelling degree and stress-strain and SEM. The best composition of coagulation bath with DMSO-H_2O is revealed. |
