Liu, Wei et Zhang, Xian Ke, Parametrization of the quadratic function fields whose divisor class numbers are divisible by three, Acta mathematica Sinica. English series (Print) , 25(4), 2009, pp. 593-596
A parametrization of quadratic function fields whose divisor class numbers are divisible by 3 is obtained by using free parameters when the characteristics of the fields are not 3.
