In this paper, we extend the uniform regularity estimates obtained by M. Avellaneda and F. Lin in [3] and [6] to the more general second order elliptic systems in divergence form class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0022247X16001359&_mathId=si1.gif&_user=111111111&_pii=S0022247X16001359&_rdoc=1&_issn=0022247X&md5=709b099b895908631f5de423771d9fdf" title="Click to view the MathML source">{Lε,ε>0}class="mathContainer hidden">class="mathCode">, with rapidly oscillating periodic coefficients.

We remark that the well known compactness methods are not employed here, instead we construct the transformations (1.11) to make full use of the results in [3] and [6].
