在足够高的密度和/或温度下，普通物质经历转变为类等离子体相，由夸克和胶子组成，而不是由单独的强子组成。由于渐近自由，这类物质的渐近性质可以用微扰计算，而在讨论相变时，人们应该集中在非微扰效应上。本文综述了这一理论的最新进展及其在强子结构、中子星、强子高能碰撞等问题上的应用。
At high enough density and/or temperature ordinary matter undergoes a transition into a plasma-like phase, consisting of quarks and gluons rather than of separate hadrons. Due to asymptotic freedom, the asymptotic properties of such matter can be calculated perturbatively, while in the discussion of phase transitions one should concentrate on nonperturbative effects. Recent progress in this theory is reviewed, as well as its applications to such topics as hadronic structure, neutron stars, high energy collisions of hadrons, etc.
