【Abstract】 By the method of Knopp-Kojima,the growths of the Dirichlet series of the exponential order in the right half plane are studied.The results of the connection between the coefficients of the Dirichlet series and the exponential order growth are obtained.(i) If a zero order series over σ>0 has exponential order μ,then limσ→0+——ln+u(σ) ln1 σv=μv=limn→+∞——ln+n(lnn)v=limn→+∞——ln+nk(lnnk)v,where nk is the main index sequence,0<μv<+∞,v>1;(ii) If σu=0 and a zero order series over σ>0 has exponential order τ,then lim——σ→0+ln+u(σ) ln1 σv=τv=lim——n→+∞ln+cn(lnn)v,where 0<μv<+∞,v>1.更多还原
