Abstract: In quantum field theory, elemental particles are assumed to be pointparticles. As a result, the loop integrals are divergent in many cases.Regularization and renormalization are necessary in order to get the physicalfinite results from the infinite, divergent loop integrations. We propose newquantization conditions for non-point particles. With this solid quantization,divergence could be treated systematically. This method is useful for effectivefield theory which is on hadron degrees of freedom. The elemental particlescould also be non-point ones. They can be studied in this approach as well.
