In this paper, we mainly employed the idea of the previous paper [34] to study the sharp uniform class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0022039616301632&_mathId=si1.gif&_user=111111111&_pii=S0022039616301632&_rdoc=1&_issn=00220396&md5=2eaaf4d4f987be7a25867ef83e8360c9" title="Click to view the MathML source">W1,pclass="mathContainer hidden">class="mathCode"> estimates with class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0022039616301632&_mathId=si2.gif&_user=111111111&_pii=S0022039616301632&_rdoc=1&_issn=00220396&md5=83d257e85eeb91a3785fdd4186e771f3" title="Click to view the MathML source">1<p≤∞class="mathContainer hidden">class="mathCode"> for more general elliptic systems with the Neumann boundary condition on a bounded class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0022039616301632&_mathId=si3.gif&_user=111111111&_pii=S0022039616301632&_rdoc=1&_issn=00220396&md5=fd3110bac11d9a19374414395b666eb4" title="Click to view the MathML source">C1,ηclass="mathContainer hidden">class="mathCode"> domain, arising in homogenization theory.
