利用一个相对论性强子输运模型，我们研究了椭圆流激发函数作为核物质刚度以及在AGS能量1 < E束流 < 11 AGeV下可能的夸克 - 胶子等离子体（QGP）相变起始的探测手段的效用。激发函数显示出对核态方程的强烈依赖性，并呈现出可能标志着向QGP相变起始的特征迹象。
Using a relativistic hadron transport model, we investigate the utility of the elliptic flow excitation function as a probe for the stiffness of nuclear matter and for the onset of a possible quark-gluon-plasma (QGP) phasetransition at AGS energies 1 < EBeam < 11 AGeV. The excitation function shows a strong dependence on the nuclear equation of state, and exhibits characteristic signatures which could signal the onset of a phase transition to the QGP.
