摘要：

We discuss corrections to the leading-log Q2 relationships between the gluon density g(x, Q2) and F(L)(x,Q2), partial derivative F(T)(x, Q2)/partial derivative log Q2 in the HERA range of large 1/x. We find that the above quantities probe the gluon density g(x, Q(T,L)2)) at Q(T,L)2 = C(T,L)Q2, with the Q2-rescaling factors C(T) almost-equal-to 2.2 and C(L) almost-equal-to 0.42. The possibility of treating charm as an active flavour is critically re-examined.
