摘　　要：研究了相对论能量下EOS实验碰撞中的末态质子的流角和"流"值，在以流方向为z轴的质心坐标系中研究了质子的极角分布，得到了不同入射束能量下质子的极角分布宽度。The flow angles and the flow values of the final state protons from Ni+cu collisions at relativistic energy were measured. By studying the polar angle distribution of the protons in the center-of-mass coordinate systems with the z axis rotated to the flow angle,the widths of the polar angle distribution around the flow direction were obtained.

关 键 词：侧向流 反应平面 流角 Ni+Cu碰撞
