摘要: A complex network with an exponential distribution p(k)\propto\e{-\frac{k}{k_{c}}}with k c =3.50±0.02 is introduced and found to have assortative correlation k i nn =B+qk i (q>0) from numerical simulation.

Abstract: A complex network with an exponential distribution $p(k)\propto {\rm e}^{-\frac{k}{k_c}}$ with kc=3.50±0.02 is introduced and found to have assortative correlation $\langle k_i^{nn}\rangle$ =B+qki (q>0) from numerical simulation.

Key words: network, degree correlation
