摘要：

We present the order alpha(s)2 correction to the deep inelastic Wilson coefficient receiving contributions from all parton subprocesses with a gluon in the initial state. Together with the (non-)singlet part calculated previously, the Wilson coefficient for the process e + p --> e + "anything" is now completely known up to order alpha(s)2. Its effect on the deep inelastic structure function F2(x, Q2) is studied. It turns out that the order alpha(s)2 corrections are appreciable (about 10%) in the large as well as in the small x region.
