Results showed that shoot biomass of H. annuus was significantly higher than that of R. acetosa and R. hastatus; among three plant species, 134Cs specific activity in shoots was the highest in H. annuus after 50 d-treatment, however after 70 d-treatment, that in R. acetosa was the highest. Bioaccumulation ratio reached 1.5, 1.4 and 1.3 in R. acetosa, R. hastatus and H. annuus after 70 d-treatment, and the former two plants kept with trend of continuously increasing. Three plants were resistant to 134Cs contaminated soil and capable of translocating 134Cs from soil to plants. Among them, H. annuus removed greatest 134Cs amount in the aboveground part during the experiment period, and R. acetosa, R.

The results show that the CNTs are dispersed effectively by bell jar immersing precast block casting. The maximal tensile strength and the elongation of the AZ31/CNTs composites are enhanced by 41.3% and 119.4%, respectively, and the elastic modulus and micro-hardness are also raised by 67.8% and 66.9%, respectively, when compared with those of the as-cast AZ31 Mg alloys. The CNTs can greatly refine the grains of the composites, playing a good role in reinforcing the matrixes of AZ31 Mg alloy. The fracture sections of the composites mainly consist of dimples and prisms, which demonstrates quasicleavage fracture modes.

Based on the relevant movement between hard shaper cutter and grinding wheel, the movements of grinding wheel are studied. The shaping grinding point and the shaping grinding edge are made up with. In order to easily compare when shaping errors and cutting edge"s angles are the most excellent, uniform expressions for convex curved rake face of hard shaping cutter and spatial cutting edge curve are separately developed. The distributions of new profiling cutter"s shaping errors and cutting edges angles are analyzed. The relevant grinding wheel and cam are designed. Due to this paper, a new profiling hard shaping cutter has been manufactured successfully. At last experiments are made to test the performance of hard shaping cutter and all kinds of precision of hard gear.
