我们推导了与重力非最小耦合的混沌膨胀模型的一致性关系。对于小非最小耦合参数限制下的二次势和不假设小的四次势，我们给出了谱指数、张量比和谱指数运行之间的一致性关系。我们发现，不像，不太敏感。如果，则将其限制为四次势。对于一般的单项式势， 被限制在 asif 的范围内。
We derive the consistency relations for a chaotic inflation model with a non-minimal coupling to gravity. For a quadratic potential in the limit of a small non-minimal coupling parameterand for a quartic potential without assuming small, we give the consistency relations among the spectral index, the tensor-to-scalar ratio, and the running of the spectral index. We find that, unlike,is less sensitive to. If, thenis constrained toandis predicted to befor a quartic potential. For a general monomial potential,is constrained in the rangeas long asif.
