The compression test on TC21 titanium alloy was carried out in the temperature range of 860~940oC and the strain rate range of 0.01~10s-1 on Gleeble-1500D hot simulation machine. And the hot deformation behavior was studied. The processing map was calculated and analyzed according the dynamic materials model. It is found that the flow stress of TC21 decreases with the increasing of the temperature and the decreasing of the strain rate. The flow stress curves are characterized by steady state at low strain rate( s-1）but discontinuous yield at high strain rate( s-1). The processing map established at the true strain of 0.4 shows that there are three regions, instability and safe and peak region, and the efficiencies of power dissipation are 0~25%，31%~37% and 43%~49% respectively. The peak region is the optimum hot working zone of TC21 titanium alloy.

The X-ray responses of the very radiosensitive S/S variant of the L5178Y murine leukaemic lymphoblast have been studied at different phases of the cell cycle. Throughout G 1 and the first half of S, survival was constant; then it rose to a maximum 8 h after mid-G 1 before falling back to the preceding (plateau) level. Although the variation in chromosomal aberration frequency through the cycle mirrored the survival response, the death of only one S/S cell in three was attributable to chromosomal aberrations. Since normally radiosensitive cells exhibit a second peak of survival in G 1 , the response of the S/S variant permitted an experimental precision not available previously for examination of the survival curves of a mammalian cell line and the extant theories concerning them. In the plateau region of cycle response, the survival curve was linear at all doses; in the peak region, however, the survival curve was linear at low doses, then it curved downward until it became linear again at high doses. Throughout the plateau region of cycle response, the survival of the S/S cells was not altered by dose fractionation, but it was increased by post-irradiation hypothermia; in the peak region of cycle response, the converse was true. That behaviour can be explained if, at all phases of the cell cycle, the survival curve of the S/S variant is determined by metabolism, presumably DNA repair, rather than by patterns of primary radiochemical damage.
