Abstract：
At Large Hadron-Hadron Collider(LHC), the structure of nucleon at much small x region can be revealed. With the high twist modified AP evolution equation (MDAP equation), the saturation problem of partons at LHC energies is analyzed. It is found that the parton distribution will not be saturated in this region, instead, due to the high twist effects, the parton distribution is obviously suppressed and partial saturation appears. With the MDAP equation, parton distributions at LHC energies are calculated.
