摘要Testing the so-called consistency relations plays an important role in distinguishing the different classes of inflation models. In this paper, we investigate the possible testing for various single-field inflation models based on the potential future observations of the cosmic microwave background (CMB) radiation, including the planned CMBPol mission and the ideal CMB experiment where only the reduced cosmic weak lensing contamination for the B-mode polarization is considered. We find that for the canonical single-field inflation, the phantom inflation and the potential-driven G-inflation, the consistency relations are quite hard to be tested: the testing is possible only if r > 0.14 for the CMBPol mission, and r > 0.06 for the ideal experiment. However, the situation could become much more optimistic for the general Lorentz-invariant single-field inflation model with large non-local non-Gaussian signal. We find that testing the latter class of inflation is possible if r greater than or similar to 10(-2) or even smaller for both CMBPol and ideal CMB experiments.
