abstract = {<p style="text-align: justify;">Aiming at the isoparametric bilinear finite
volume element scheme, we initially derive an asymptotic expansion
and a high accuracy &nbsp;combination formula of the derivatives in the
sense of pointwise by employing the energy-embedded method on
uniform grids. Furthermore, we prove that the approximate
derivatives are convergent of order two. Finally, numerical examples
verify the theoretical results.</p>},
