１．１８重离子碰撞中的集体流卢兆启，李祝霞在重离子碰撞过程中，由于入射核和靶核之间的高速相对运动，在碰撞区产生强大压力，而垂直于束流方向的压力却小得多，因而产生横向集体流，所以横向集体流的产生标志着高压核物质的形成，研究集体流成为探测核物质状态方程的... 1.18 Collective flow in heavy ion collision LU Zhaoqi, LI Zhuxia In the process of heavy ion collision, due to the high-speed relative movement between the incident nuclear and the target nucleus, strong pressure is generated in the collision zone and the pressure perpendicular to the beam direction is small Resulting in a horizontal collective flow, so the emergence of a horizontal collective flow marks the formation of high-pressure nuclear matter and the study of collective flow as a state equation for the detection of nuclear matter ...
