    "abstract": "We carry out a detail study of elliptic flows in Au-Au collisions at 200 AGeV\nin a quark combination model. We find that elliptic flow data for a variety of\nhadrons can be well reproduced except pions if constituent quarks with equal\nparallel transverse momenta combine into initially produced hadrons. In a\ncombination mechanism where initial hadrons are formed by quarks with unequal\nparallel transverse momenta, theoretical predictions agree with data for all\navailable hadrons including pions. The mass hierarchy at low transverse momenta\nin elliptic flows can be understood in the same quark combination mechanism as\nin the mediate range of transverse momenta.",
