For probing the isospin dependence of the medium correction of two-body cross sections, the results show that the behavior of the excitation function of stopping for medium size nuclear collisions can provide clearer information than that for heavier systems.

我们的结果还表明测量中等大小质量的系统在中能重离子碰撞中的核阻止本领激发函数比测量重的系统能提供更为确切的有关两体截面介质修正的信息。

We consider that the better system of measuring for the size of granular mixtures may be the number of elements. So we designed another kind of large system experiment, the experiment of Tokamak plasma system with the characteristic of jillion element. Under the condition of Ohmic heating and Low confinement mode, the interaction among elements will increase with the debasement of plasma confinement, causing SOC.It validates the assumption that SOC mostly depends on the mechanism of interaction among elements in a large system, in other way.
