The finite growth of Escherichia coli was studied by using a LKB 2277 BioActivityMollitor. We found that the finite growth is a nonliear dynanic process. The nonlinear dynamicbehaviour in the finite growth process and the monlinear dymanic models describing the processwere discovered and established. The curve of logistic map corresponding to the finite growththermogram of Escherichia coli was obtained and the nonilnear dynamin parameters were calculated by means of a computer. Moreover. we also discussed the nonlinear dynamic characters ofEscherichia colt in its finite growth process.
The thermal denaturation of the rice mitochondrial DNA in different solutions have been studied by using ultraviolet absorption spectrometry at 50 ℃, and their kinetic behaviour of the thermal denaturation has been discussed. The kinetic curves of the thermal denaturation of rice mitochondrial DNA in different solutions have been obtained, and the kinetic parameters and models have been calculated and established respectively.
