Popis: We obtain spin-dependent singlet, nonsinglet, and gluon structure functions by solving Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equations in leading order and next-to-leading order at low $x$. The Taylor series expansion method is used to solve the evolution equations. We also calculated $t$ evolution of longitudinally polarized proton and neutron structure functions ${g}_{1}^{p}$ and ${g}_{1}^{n}$, respectively, and the results are compared with SLAC E143 data.
