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.

探讨了采用硫酸钡共沉淀法去除甲磺酸(MSA)镀锡液中铅杂质的可行性,重点研究了沉淀剂(Ba(OH)_2·8H_2O)的投入量、反应时间及沉降时间对除铅效果的影响。使用扫描电镜(SEM)、能谱(EDS)、X射线衍射(XRD)、激光粒度分析等方法对共沉淀物进行表征。结果表明,当Ba^(2+)/Pb^(2+)摩尔比为25,反应时间为30 min时,所得共沉淀的粒度最大,镀液中的铅含量从16.11 mg/L降至0.70mg/L,而延长沉降时间有利于进一步降低镀液中的铅含量。共沉淀物主要为(Ba_(0.69)Pb_(0.31))SO_4。
