A Study of Quasi-Exactly Solvable Models within the Quantum   Hamilton-Jacobi Method
  A few quasi-exactly solvable models are studied within the quantum Hamilton-Jacobi formalism. By assuming a simple singularity structure of the quantum momentum function, we show that the exact quantization condition leads to the condition for quasi-exact solvability.
