The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.

为了实现对材料内部较深层缺陷的大小和深度的检测,采用弹性理论分析并结合离面位移数字散斑干涉实验的方法,分析了含内部缺陷试件的离面位移分布,并给出了理论解。同时用数字散斑干涉和数值仿真得出试件的离面位移,将3种方法得到的离面位移及其1阶导数的分布做了对比,由对比结果可知,理论、实验及仿真得到的结果非常吻合,并对误差做了分析。从实验得到离面位移的1阶导数可获得缺陷的大小,结合理论计算出缺陷的深度,二者的误差都在允许范围之内。结果表明,利用离面位移数字散斑干涉系统测量材料内部较深层缺陷具有很高的准确性。
