根据一般纤维的Clifford指数，给出了离散有理曲面的斜率不等式.对于Clifford指标为2的离散有理曲面，完全确定了最大秩的Mordell-Weil格.
Slope inequalities are given for fibred rational surfaces according as the Clifford index of a general fibre. For fibred rational surfaces of Clifford index two, the Mordell-Weil lattices of maximal ranks are completely determined.
