摘　　要：The Skyrme parameter sets were widely used in nuclear structure calculations which did notThe Skyrme parameter sets were widely used in nuclear structure calculations which did not include the sensor contribution. Until recently, some attentions have been paid to study the effects of the tensor force on the evolution of the shell structure of atomic nuclei. In an attempt to reach a global view of the effects of the tensor interaction on single-particle states in nuclei, we analyze the role of the zero-range tensor associated with a Skyrme-type effective force on the spin-orbit splitting in Ca isotopes and in the N=28 isotones. The role of the surface and volume pairing forces are discussed. The different role of the triplet-even and triplet-odd tensor forces is pointed out by analyzing the spin-orbit splitting in these nuclei.
