Abstract：
By using the distribution functions of the valence stratons with definite helici-ties, the differential cross sections and asymmetries of 1. the deep inelastic scatteringprocesses of electrons on polarized protons, polarized neutrons and polarized nucleons,and 2. the process p+N→μ⁺μ^-+X (where the p and N are polarized) are comput-ed. From the kinematics, it is shown that no polarization effects exist in the process π(K) +N→μ⁺μ^- + X (where N is polarized). Also from the parton model it isshown that no polarized effects exist in the process P + N→μ⁺μ^- + X (where P and N are polarized).
