研究了修正的波恩夸克模型中的相结构和相变。描述粒子-空洞型相互作用的力强度依赖于夸克数，即夸克数密度。结果表明，随着密度的增加，发生了从作为核子的夸克三重态到作为色超导的夸克对态的相变。
A phase structure and phase transitions are investigated in the modified Bonn quark model. The force strength, which represents the particle-hole type interaction, is devised so as to depend on the quark number, namely quark number density. As a result, it is shown that the phase transition from the quark-triplet state as a nucleon to the quark-pair state as a color-superconducting state occurs as the density increases.
