Query: Generalized Steiner's Problem and its Solution with the Concepts in
  Field Thoery   We generalized the Steiner's shortest line problem and found its connection
with the concepts in classical field theory. We solved the generalized
Steiner's problem by introducing a conservative potential and a dissipative
force in the field and gave a computing method by using a testing point and a
corresponding iterative curve.
