摘要：

The main goal of this paper is to derive the primordial power spectrum for the scalar perturbations generated as a result of quantum fluctuations during an inflationary period by an alternative approach of field quantization, i.e. Krein space quantization (Gazeau et al. in Class. Quantum Gravity 17:1415, 2000; Takook in Int. J. Mod. Phys. 11:509, 2002; Rouhani and Takook in Int. J. Theor. Phys. 48:2740, 2009). The spectrum of scalar curvature perturbations are calculated in the slow roll approximation.
