Shown are different results for different methods of calculating the scalar index ns.

These were calculated for the 3 example potentials mentioned in Table 2. The first is the numerical result. Next is the standard Stewart & Lyth expression Eq (B:45). Another result is given by using (14), without substituting potential and derivative expressions for slow roll parameters. Finally we use Eqs (B:40,36,42), to accurately assess the scalar index.以下结果均针对表2中提及的3个示例势场（potentials）计算得出。第一项为数值计算结果；第二项为标准的Stewart与Lyth表达式（式B:45）；第三项结果通过采用式(14)得到，且未将势场及其导数表达式代入慢滚参数（slow roll parameters）；最后一项则通过采用式B:40、式B:36与式B:42进行计算，以精确求解标量谱指数（scalar index）。
