英文摘要	In this letter we present a new inflationary model composed of multiple scalar fields where each of them has its own dbi action. we show that the dependence of the e-folding number and of the curvature perturbation on the number of fields changes compared with the normal n-flation model. our model is also quite different from the usual dbi n-flation which is still based on one dbi action but involves many moduli components. some specific examples of our model hive been analyzed.
