For periodic smooth solutions, we justify an asymptotic expansion in a time interval independent of the Debye length. This implies the convergence of the equations to compressible Euler equations. The proof is based on energy estimates for symmetrizable hyperbolic equations and on the exploration of the coupling between the Euler equations and the Poisson equation. <\/jats:p>","DOI":"10.3233\/asy-131177","type":"journal-article","created":{"date-parts":[[2019,11,30]],"date-time":"2019-11-30T00:30:09Z","timestamp":1575073809000},"page":"125-148","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["From two-fluid Euler\u2013Poisson equations to one-fluid Euler equations"],"prefix":"10.1177","volume":"85","author":[{"given":"Yachun","family":"Li","sequence":"first","affiliation":[{"name":"Department of Mathematics and MOE-LSC, Shanghai Jiao Tong University, Shanghai, China.
