thank you very much!

I donot know other function fields not RationalFunctionField,cound give more?

Real Field is not a RationalFunctionField? is there a polynomial?

F[RR](t},even F[CC](t} is RationalFunctionField.like p-adic,whether F(Qp)(t) is a RationalFunctionField?

there a word name totally_positive in Real Field ,and there a function named is_totally_positive() in Global Number Fields,the same meaning?

thank you very much!
