Abstract：
In this letter we give another representation of the βform 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 βforms are consistent with the results that appear in literature. The βform is essential for the calculation of the D-brane domain wall tension, and a convenient choice of βforms should simplify the calculation. The freedom of the choice of βforms shows some symmetries in Calabi-Yau space.
