在低能或中能核-核碰撞中,因有效相空间体积较小故泡利阻塞效应很重要。不过相对论性核-核碰撞中由于动量相空间体积很大,而且95%以上的产生粒子是玻色子,所以泡利效应通常被忽略。我们认识到:虽然产生粒子,如π和k等是玻色子但它们的上一代粒子,即u、d和s夸克则是费米子,它们 In low-energy or medium-energy nuclear-nuclear collisions, the bald blocking effect is important because of the small effective phase space volume. However, the relativistic nuclear-nuclear collision due to the large volume of momentum phase space, and more than 95% of the particles are produced boson, so Pauli effect is usually ignored. We recognize that although particles such as π and k are bosons, their previous generation of particles, u, d and s, are fermions, and they
