摘要：
通过要求反弹是非奇异的，并且扰动在任何时候都表现良好，我们缩小了具有一个自由度的可能模型的范围，该模型可以在没有空间曲率的情况下描述反弹。我们计算的传输矩阵的扰动通过反弹的一般性质，并表明，光谱扭曲的Barnesian潜在的$Φ$一般只产生的小波长，虽然长波长的曲率扰动产生的光谱收缩阶段得到传播不受影响通过这样的反弹。
英文摘要：
By demanding that a bounce is nonsingular and that perturbations are well-behaved at all times, we narrow the scope of possible models with one degree of freedom that can describe a bounce in the absence of spatial curvature. We compute the general properties of the transfer matrix of perturbations through the bounce, and show that spectral distortions of the Bardeen potential $Φ$ are generically produced only for the small wavelengths, although the spectrum of long wavelength curvature perturbations produced in a contracting phase gets propagated unaffected through such a bounce.
