It is shown that deformation temperature is the main factor that influences the static recrystallization behavior. Carbonitride precipitation inhibits recrystallization and causes a plateau in the softening ratio curve. The static recrystallization activation energy of X80 pipeline steel was regressed and calculated to be 380 kJmol^(-1), and its rationality was also discussed according to previous references and investigations.

Temperature, clone and their interaction influenced significantly the neonate starvation, and body, egg and neonate volumes in the offspring of B. calyciflorus. The neonate starvation times of all the thirteen clones were curvilinearly correlated with temperature. The neonate starvation times of Clone SP1 was negatively correlated with body volumes. The neonate starvation times of Clone SP2 was negatively correlated with neonate volumes, but that of Clone SU1, SU3 and SU7 were positively correlated with neonate volumes.

The results manifest that the concentration of glycocholic acid has satisfactory linear correlation whith peak area, regression equation: Y= 39579X + 57823,R2=0.9984;The lowest detected concentration is 0.02μg/mL with S/N=3 ; Average recovery rate is 98.49%; RSD为0.52%～2.00%in day, RSD为0.74%～4.98%between days;The average recovery rate is 99.35%, RSD is 2.24% in the first team, and it is 100.87%, RSD is 4.73% in the second team at the stability test. When the concentration of glycocholic acid was detected in the liver, kidney and brain tissue, corresponding tissue concentration was calculated by preparing the standard curve with the glycocholic acid standard preparation in vitro, but the result can only reflect the relative chang law of the concentration of glycocholic acid in tissue but not in real tissue. The result of tissue stability experiment is consistent with that of the serum experiment.
