ABSTRACT: First, Schrödinger equation and its some applications in DNA, etc., are studied. Second, we research the energy-momentum representation and basic equations, and which are applied to the lifetimes formulas of hyperons. Third, we search possible unified equations of fermions and bosons, both correspond to j+(1/2) order Bessel equation in spherical coordinates, and m order Bessel equation in column coordinates. Finally, we discuss possible 16 type developments of quantum equations.
