摘要：

We show two analytical solutions of the tachyon inflation for which the spectrum of curvature (density) perturbations can be calculated exactly to linear order, ignoring both gravity and the self-interactions of the tachyon field. The main feature of these solutions is that the spectral indices are independent of scale.
