摘要 A mono-component spherical system has been studied under various initial conditions,and an analytic representative p(r=0,t)=p_(0)(1-(D,t)^(2))of the density at the center of the system has beenfound under the condition that the initial radius of the system r0】Dr The theoretical characteristic constants,the critical radius D^(-1)_(r)=(3kT/4πm^(2)n_(0)G)^(1/2)and the gestation D^(-1)_(r)=(3/4πmn_(0)G)^(1/2)exp(l:24),are dependent on the initial density p0=mn0t and the initial absolute temperature T at the center of the system These theoretical values accord with the corresponding values of astronomy.These results are helpful lor solving the problem of how stars were formed in the universe.
