| Abstract: | The reaction diffusion equation is generalized in gravitational and nonisothermal system.Because the new equation contains gravitation and temprature gradient,there is not homogeneous stationary state solution of it.The stable condition of CON cycle in reference(4)has been changed into D,K~2-B:(r)>0.This shows it has been strenthened by gravitation. when condition Vg/g=VT/T is satisfied and VT considered constant,the generalized equation has the homogeneous stationary state solution and stability conclusion of the reference(4)is not changed. |
