摘要：

We calculate Lambda and (Lambda) over bar hadron production cross sections in charged lepton semi-inclusive deep-inelastic scattering off nuclear target (A, using iron Fe as an example) and deuteron (D) target. The results show that the ratio ((Lambda) over bar (A)/Lambda(A))/(Lambda) over bar (D)/Lambda(D)) is sensitive to the sea quark content of the nucleus. We adopt three different models to take the nuclear EMC effect into account. The ratio ((Lambda) over bar (A)/Lambda(A))/((Lambda) over bar (D)/Lambda(D)) is predicted to be different by these different models.
