Simulation shows that the inhomogeneity of electric field reduces the oscillations in photodetachment cross section and its corresponding modulation function.
This method can avoid the repetition and pretermission of integrating interval (or summarizing interval), especially in the convolution computation of multi-partition function.
Axisymmetric elasticity problem of cubic quasicrystal is reduced to a solution of a partial differential equation with higher-order by introducing displacement function.
