Abstract: Under the Hartree mean-field approximaion and the high-temperature approximation,we established the mapping relation between some types of the special solutions of the φ4 model and the nontopological soliton bag model.From the mapping relation we see that nonspherical topological kink and antikink of φ4 model are paired to form bound state——the nonspherical nontopological soliton solution of the nontopological soliton bag model.The symmetry restoration phase transition of the φ4 model occurs when the topological kink and antikink disappear; And the deconfinement phase transition of the nontopological soliton bag model occurs when the bound state of the topological kind and antikink (nontopological soliton) vanishes.
