In this letter we give another representation of the beta form in the inhomogeneous Picard-Fuchs equation for open topological string for some one-parameter Calabi-Yau hypersurfaces in weighted projective spaces. Furthermore, the corresponding domain wall tensions calculated by using these beta forms are consistent with the results that appear in literature. The beta form is essential for the calculation of the D-brane domain wall tension, and a convenient choice of beta forms should simplify the calculation. The freedom of the choice of beta forms shows some symmetries in Calabi-Yau space.
