Both a reversion and an increase of the absolute value of specific rotation in the transformation from MALM to PMALM- b -PSF- b -PMALM were observed,which were probably caused by some kind of stereostructure of the main chain formed during the polymerization due to the intermolecular hydrogen-bonding.

Results: 1. A collarless press fit canine femoral stem of CFRPSF composite (elastic modulus was 40 GPa, containing carbon fiber 30%) using HA (50%) and PSF (50%) composite for surface coating was made. Directions of carbon fiber in the stem were similar to the arrangement of trabeculae of proximal femur.

It is revealed that both the roasting and cooling air flow run radially at inlets and then run slantingly upwards or downwards into roasting-preheating zone inside IVAC. And the gas flow in the whole soaking zone is weakened. There are possibly three gas flow patterns in PSF, which are mainly dependent on the ratio of inflow, i.e., the greater the ratio is, the higher the downward roasting air flowrate and the lower the upward air flowrate will be. The critical ratio of inflow mainly depends on the constructional parameters and packed bed conditions of PSF.
